1 General

What is ShareWaste? ShareWaste is an international grassroots volunteer-run initiative founded and managed by Eliska Bramborova and Tomas Brambora. Our aim is to encourage people to see their organic waste as a valuable resource and help them turn their waste into new soil and fertiliser by connecting them with other community members. We help people connect through our free app. ShareWaste does not manage any composting sites – all locations on our map are in private, council or commercial hands. Each site is registered by an individual or a coordinator who is responsible for that compost site.

Where is ShareWaste available? ShareWaste app has a grxowing user base all over the world - new users register every day. Anybody can download the free ShareWaste app, sign up and start using it.

I want ShareWaste in my town / neighbourhood / area. What can I do? Thanks to our online platform and mobile apps, ShareWaste works anywhere where people decide to use it. ShareWaste can even be beneficial in areas that already have kerbside organic waste collection - there is much lower risk of contamination and it is a great feeling to know and see what your kitchen scraps contribute to!

The best way to bring ShareWaste to your town or neighbourhood is to register and spread the word about us there. Everywhere.

Do you have apps for smartphones? Yes, of course. :) You can download them for free here:

How can I receive organic waste? Depending on who you are you can register as an individual compost host or a community garden. After you have registered and filled out a short form, you will have a marker on the ShareWaste map. Registered donors will be able to send you a message to start donating their organic waste.

How can I donate my organic waste? You can register as an organic waste donor or a cafe (hospitality business). Cafes can connect with their community to donate their spent coffee grounds, food waste or other organic matter.

What is a drop-off/hand over? A drop off/hand over is a previously arranged visit when a donor comes to the host's location and delivers a batch of their waste. We recommend the hosts to be present at least for the first drop-off of every new donor to show them everything, explain how composting works, what items are acceptable and how the processed waste will be used.

What happens to the donated waste? The waste is recycled and the host usually uses the final products (compost, worm juice or other) in their garden or farm.

2 Registration and Verification

How do I register a cafe? Sign up, open https://sharewaste.com/entity/create?type=coffeePlace and fill out a short form. And that's it. :)

I haven't received a verification email Please give it some time. It can take up to 15 minutes for the email to arrive in some cases - email can be slow. If you have already waited long enough and still can’t find the email, check your spam/junk/promotions email folder. If you don't find the email there, go to your profile page in ShareWaste and hit “resend verification email”. Please mind that due to security reasons, only the link in last sent verification email will work. If none of this helps, send us an email and we can verify you manually.

I want to change my email address You can change your email address from your profile page. Please note that at the moment you cannot change your email address if you have signed up with Google social login (i.e., via the Google button). If you have signed up with Google, please email us and we can help you change the address.

I wanted to register as a host/donor but it seems I got that wrong? Not to worry. If you registered as a donor but you want to be a host, simply add a listing to your profile from the profile page (in the "Add map listing” section) and you’re all sorted. If you have accidentally signed up as a host, simply don’t fill out the new listing form - hosts can still act as donors (i.e., send messages to other hosts) in ShareWaste.

3 My Account

I forgot my password Please use the “I forgot my password” link on the sign in screen to send yourself an email with a link to change your password.

I would like to change my password The best way to change your password is to use the “I forgot my password” link on the sign in screen to send yourself an email with a link to change your password.

How can I change my email? You can change your email from your profile page. If you have signed up with Google login, please send us an email and we can change the address for you.

How can I edit my profile details? You can change your profile details on the Profile page.

I have moved and would like to change my address? You can update your address on your Profile page. If you are a host, you can update the listing address from the listing setting (accessible from the Profile page).

How do I edit the details of my compost listing? You can update the listing address from the listing settings (accessible from the Profile page).

How do I delete my account? There is a “delete account” button at the bottom of your Profile page.

I have accidentally deleted my account. Can I have it reinstated? Send us an email, we can probably help you.

I’m concerned about privacy. What information can other people see about me? If you are a compost host with an active compost, other registered users can see:

  1. A map marker showing the location of your listing and the street name (without street number)
  2. The information you wrote into your public profile and your small profile picture.

If you would like to point the map marker away from your exact location for privacy reasons (e.g. to point it at the street rather at your house), you can do that from your listing settings page (click the "customize marker location" link).

Here is our Privacy Policy in full for you to review.

We use SSL encryption for all data (that means we don’t send anything in plain-text over the Internet). If you have any concerns about your privacy, please contact us on [email protected].

What is the ShareWaste impact tracker and how do I use it? ShareWaste impact tracker is a super easy way to keep track of how much organic waste you have received or donated. You can see it in action at https://sharewaste.com/impact . Every time you donate or receive scraps, you should enter information about the contribution and we’ll keep track of your all time stats. We’ll be adding more features to the tracker, so stay tuned!

4 Map

What do the markers on the map represent? You can click on the question mark button on the ShareWaste map to see the map legend. In short:

  • Green icon of a compost is an active compost host you can reach out to
  • Chicken icon represents a compost host who keeps chickens, other animals and may have a compost bin / worm farm as well.
  • Grey icon is a non-active compost host
  • Orange flower icon stands form community gardens, farms and other community places
  • Coffee bean represents a cafe or another small hospitality business

How do I find the nearest compost bin and contact the owner? First, register as a scraps donor. Once you have verified your account, you can open the map, click on the marker of your chosen compost host and send them a message. If there is no host near you, have a look if there isn't one near another place you visit regularly (your workplace, your children's school or parents' house, gym, etc.).

Why there are none or just a few markers in my area? ShareWaste is a free app and we grow mostly by word-of-mouth fuelled by our users' enthusiasm and interest. The most common reason for there being only a few markers on the map in your area is that people simply don't know ShareWaste exists or nobody has spread the word about it yet. And you can change this!

I can't see any markers on the map First the usual advice: make sure you are connected to the internet, reload the page, use another internet browser (ShareWaste supports all widely used modern browsers). If none of these work, open the app on another device (e.g. your mobile, laptop). If you still can't see any markers, you’ve probably found a serious bug and we would appreciate if you would let us know! :)

Code of Conduct aka Community Ethics ShareWaste as an app and a platform has two main goals:

  1. Divert nutritious organic matter from landfill and turn it into new soil and fertiliser; and
  2. Bring people together.

These two goals are equally important to us so after you have registered, please take a minute to read our Community Ethics:

How to be a good compost host - Be responsive. If you receive a message, try to respond as soon as possible. Somebody has decided to voluntarily collect their organic waste and deliver it to you and we wouldn’t want to risk them losing their “momentum”. Always remember: a "I'm sorry, I can't accept anything at the moment*" reply (even with a month's delay) is a better reply than no response at all.

  • Give enough information. Always provide specific information about what items you accept and what not (in your profile listing and consequently in conversations with new donors). If your location address changes, don't forget to change it in your listing and let your current donors know in advance.

  • Prevent disappointment. If you can't temporarily accept waste, disable your compost. This will save you from unwanted emails or messages and won't lead to sad or disappointed donors.
    If you know you won't be able to accept waste from your current donors, inform them in advance. They need enough time to find an alternative solution; we know from experience it can be heart-breaking to see one’s waste ending up in garbage again after starting to recycle it!

  • Share knowledge and skills. Make sure your donor knows what to expect at the drop-off and always give them correct and complete information. Explain to them how you recycle their waste and use the finished products. Don't be shy to share the skills and knowledge you have – many donors would love to be able to compost themselves one day and grow their own produce. You can be the one who sparks their interest or even helps them get started!

  • Be supportive and show appreciation. Most donors start from scratch and often know little about composting. They had been throwing their organic waste into garbage for a long time and recently decided to change this and start to recycle voluntarily. For most, this is a significant change in their lifestyle, and they need to form new habits around it - which is not easy. Show them you appreciate their efforts and that you are grateful for what they do. Sometimes it makes all the difference.

  • Stay in touch. If you feel comfortable with this, you can exchange email addresses or contact numbers for easier communication. Be a good community member and show interest. If you haven't seen your donor for a while, don't hesitate to get in touch with them to check how they are doing.

How to be a good waste donor - Respect private property. Always contact your chosen host to make sure they are accepting waste at the moment, to find out what items they accept and how the drop-off will work. Never drop off any waste without previous communication with the host and their consent to enter the property if the drop-off spot is located on private property.

  • Follow the host’s rules. Every host has their own rules. Make sure you know them well. Find out what items the host accepts and what not, in what form and how often. Ensure the people you share your household with are aware of this information as well. No host deserves to see plastic in their compost bin, wrong items in the worm farm or leaking paper bags with scraps on their porch. If a hosts asks you to stir the compost/add water/cover the top with mulch etc., always follow the routine to keep the their compost in top condition.

  • Create a routine. Once you've done your first drop-off, find a routine and stick to it so that the host knows when and how often to expect your visit. Connect your regular drop-off with an early morning run, afternoon walk with your dog or a short diversion on your way to pick-up kids from school.

  • Be responsive. If you receive a message, try to respond as soon as possible. If you have contacted a host and decided not to start composting with them, always thank them for replying. “Thank you, I have found a closer host to my home” is always a good reply. We’re building a community network that brings together people who care. Please show that you care and don’t leave the kind hosts hanging.

  • Be polite and show appreciation. Everybody loves to be appreciated - our hosts who often go above and beyond to cater to several waste donors, open their gardens to them and manage waste produced by several families in their own time. So say it and write it: thank you. After all, there is nothing like “too many thank yous”. ;)

  • Stay in touch. If your host feels comfortable with it, you can exchange email addresses or contact numbers for easier communication. Be a person your host will always be happy to see and talk to. Don’t forget to let them know if you are going on holidays and won't come to drop off or if you have found a closer host and won't be contributing to their composting bin any more.

5 For Hosts

Who is a host? A (compost) host is a household, business or a community place that can process excess organic waste. A host registers to receive organic waste from waste donors who contact him via the ShareWaste app. The donors deliver the waste to host’s place (unless agreed otherwise) and the host recycles it in their compost system or uses it to feed their animals . The finished products of composting are used in the host’s garden.

Who can become a host? If you can recycle more organic waste than you are producing you can probably become a ShareWaste host! Hosts are individuals owning worm farms or compost bins, keepers of chickens and other farm animals, community gardens, (city) farms, churches, community centres, businesses (yoga studios, gardening centres, and other), local compost hubs or council run community composting places.

How do I register as a host? Visit sharewaste.com or download our free app to register:

Can I register two or more locations under the same email address? At the moment not. If you wish to add another compost location, please use another email address. If you represent a council and would like to add public compost drop-off points, please contact us on [email protected] .

How do I get contacted by waste donors? Donors who choose you as the most suitable host will send you a message via the app. You will receive the message also by email and if you have downloaded the app and ticked “receive notifications” box, you should see a push notification on your phone too.

Can I contact donors myself? Unless the donor has already contacted you, you can't send them a message.

Can I see donors' locations on the map? No, the map only displays location of compost hosts (so that they are contactable by donors).

What information should I write in my profile? Be specific. All organic waste is compostable so “everything organic” or “compostable” is not a very useful description unless you are ready to receive compostable nappies, cat poo, garden waste etc. If you have a worm farm, say so and let people know what size the scraps roughly should be. If you can't accept e.g. citrus, bokashi/fermented waste or other items, say so. You can communicate more detailed information when arranging the first drop-off with the donor.

What information do I need to share with the donor? For what you can/cannot accept, please see above. When being contacted by a donor for the first time, they will need to know in detail:

  • what you will/will not accept
  • what is your exact location and how to get there (we don't display this information publicly)
  • when they can deliver their waste and in what form

I haven't been contacted by anybody yet
Your first contact may take some time depending on how many donors are active in your area. The best thing you can do (besides waiting) is spreading the word about the app!

Here's a few tips on what you could do:

  • Follow us on Instagram and Facebook
  • Let the local Council / environmental organisations know about us
  • Invite your friends and family to join
  • Spread the word on social media, share us in relevant Facebook groups
  • Write a story about us on your blog or other platform
  • Put a poster on your local community notice boards (you can download it from the main www.sharewaste.com) page

The marker on the map doesn't show my correct location Unless the location is completely off, this is ok. In case of private places the marker is often only approximate. The exact address and how to get to the compost host is something the donor should receive from you (i.e., the host) when arranging the first drop-off.

Some people have contacted me but didn't message me back or have dropped-off only a couple of times and stopped Most donors contact more than one compost host in the area and depending on when they get back to them, pick the most suitable donor. Sometimes people register, give it a go but find it too hard to keep it up. That’s life and nothing to be worried about. If you have been in touch with somebody and haven’t heard from them, feel free to send them a message.

What is the best hand over / drop-off system? The best system is the one that suits both the host and the donor, which means that the best system is customised. The system can vary from host to host but there are two most common practices our compost hosts have in place:

First, the compost host keeps several spare sealable containers at an accessible place. The donor simply swaps their full container for an empty one, which they then take home. It is up to the host, whether they ask the donors to empty their container into their compost or if they prefer to do this themselves.

Second, the donor delivers their waste in a container or a bag, which they leave at a designated place or which they give to their compost host in person at an arranged time.

In case of community gardens and other community places (council run compost hubs and similar) it depends on their internal rules. Usually they have fixed opening hours and times for drop-offs, e.g. synchronised with the days and times of their working bees.

What is bokashi? Bokashi is a Japanese method of recycling organic waste by adding bacteria during an anaerobic process of fermentation. The final product of the bokashi method is fermented waste and bokashi juice. The juice can be used diluted as garden fertiliser whereas the waste should be buried directly underground, e.g. in an unused vegetable patch, or composted. The bokashi method is often used by apartment dwellers who collect their kitchen waste in a bokashi bucket. Many of them don't have an access to a garden a for that reason they contact compost hosts to find a place to dispose of their fermented waste. Bokashi waste produces very strong sour odour but it is full of nutrients and many gardeners claim it breaks down faster in compost/soil than unprocessed food scraps.

Learn more about bokashi here: https://blog.sharewaste.com/why-you-want-to-need-the-bokashi-method/

How shall I best communicate with my donors? ShareWaste is all about building connections and trust and we hope you will become friends with your donors. You can exchange phone numbers to make the future communication easier; however, please use common sense - as you would when you meet someone new. We recommend you meet with each donor in person (unless you have a publicly accessible composting bin system). We also recommend you set clear rules about how a drop-off works to avoid confusion or mistakes.

How do I ensure the donors bring me acceptable items only? Here are a few things you can do to receive the right items only:

Provide enough information

Be specific in your profile details and include items you accept as well as those you don't. Show the donor how composting works and how to manage compost

Meet with your donor

Meet every new donor in person for a friendly chat and to show them how composting works and how to do things right, remind them again what items to include and what not

Show the donor the end product

Make sure your donors know how you plan to use their scraps - this contributes immensely to their motivation and encourages them to treat your compost (or chickens) as their own

Have a management system in place If you have more donors and they drop-off their waste at their convenience, make sure they you've walked them through the whole process and they know what to do even if you're not there (leaving a laminated note with the basic few rules is a good idea).

Be helpful and supportive

Most donors start from scratch - that means that until now they had been throwing all their organic waste into garbage from where a waste truck would deliver it to landfill. Their decision to recycle organic waste is a significant change in their lifestyle, which comes with some new habits they need to get accustomed to. Be kind. Show them that you appreciate their efforts and that you are grateful for what they do.

Stay in touch with your donors

Be a kind and friendly person they can feel comfortable having a chat with. Share useful information. You will probably find that there is more you have in common than an interest in organic waste.

My donor puts in items I can't compost or does something else I'm not happy with The most common reasons for this happening are:

  • The donor doesn’t have detailed enough information on what you can/cannot accept
  • Another family member in their household throws in the wrong things
  • You have several donors and you haven't been in much contact with them or have no management system in place

How to resolve this issue:

  • Get in touch with your donor(s) - best to talk to them in person!
  • Politely explain what happened, why it is harmful to your compost or what issues it’s causing
  • Unless you already know the reason, try finding out why that happened (they didn't know, there was a friend visiting who didn't know etc.)
  • Make sure the donor knows what to do better next time

If this is a reoccurring and upsetting issue, the utmost solution is to inform your donor that you will not accept any more donations from them. Your compost, your rules. Just please remember: no waste donor wants to do things intentionally wrong. There is usually a lack of information or relationship rapport that causes these troubles. It can be fixed.

Can I have more than one donor? Yes, and most people do. Make sure you have a well-functioning management system in place – with more donors and no direct contact with them you could increase the risk of compost contamination or waste overload.

Can I send a message to all my donors? Yes. It is possible on our mobile phones and mobile apps (coming soon on desktop browsers too). You can select multiple recipients from the message page and reply to all of them.

I would like to receive more organic waste Simply say “yes please” to more donors when they reach out to you! If you still want more, you can collect waste from your neighbours, work place, local cafe etc. There is organic waste ending up in landfill on every corner.

My compost is up to capacity, I can’t accept any scraps at the moment If you don't wish to accept more waste, disable your compost listing in your profile details. This way your marker on the map turns grey and new people won't be able to see your profile details and contact you. When you're ready to accept new waste, you can always untick the box in your profile listing and re-enable the map marker. If you know your compost will be soon up to its capacity, please inform your donors in advance so that they have time to find an alternative compost host or solution.

I'm going on holidays / moving / unable to accept waste in future First, disable your compost listing so that new people can't contact. Second, let all your current donors know so they can get themselves organised and find an alternative. It's very disheartening for people who already got into the habit of recycling their scraps when they have no better choice but throw their scraps into garbage again.

I have moved houses Please read the above. If you wish to receive waste in your new location, change your home address in your profile details.

How do I disable my compost listing? Go to your listing details and uncheck the “Accepting waste” checkbox.

My compost listing seems to be disabled, how do I change that? Go to your listing details and check the “Accepting waste” checkbox.

How do I remove my composting space from the map? If you wish to remove your composting space from the map and maintain your ShareWaste account, please contact us.

6 For Donors

Who is a donor? A donor is someone who produces organic waste and makes a decision to donate it to a compost host rather than putting in in garbage (and adding to landfill).

Who can become a donor? A donor can be an individual, a household, a work place, a cafe or other small business producing organic waste suitable for home composting. This includes food waste, egg shells, fruit and vegetable scraps, shredded garden waste, untreated timber waste (mulch, saw dust), spent coffee grounds or grains and other compostable items.

How do I register as a donor? Visit sharewaste.com or download our free app and click on Register as a donor.

How do I get in touch with a compost host?
Open the ShareWaste map (either in the app or at https://sharewaste.com/share-waste). The map should automatically center on your location but you can also use the address bar at the top if it doesn’t. Check to see if there are any markers on the map nearby. Click or tap on any marker to open the listing profile. There’s a “connect with me” button that opens a chat view. You can send a message to the host from here. Introduce yourself briefly and ask if it would be OK to donate your organic waste (it’s always good to mention how much waste you would be donating to make sure the host has enough space for it). When you send he message, the host will receive a message in ShareWaste, an email and (if they use the mobile app) a mobile notification.

I have just registered as a donor what shall I do now? 1. Browse the map to find a suitable nearby host and send them a message to offer them your organic waste. Please note that except for community spaces with public access, all compost locations are on private land and you do not have right to enter them or use the compost bin unless the property owner has allowed you to do so! 1. Find a suitable container to collect your waste in and a good spot to store it
1. If the compost host has already replied, communicate with them what items they can accept, in what form how much and how will the drop-off work
1. If the compost host hasn't replied or wasn't a good match for you, keep contacting other hosts until you find a good fit for you. Please be a good person and always reply back to people even if you are not planning to make another contact with them. We’re building a friendly community.
1. Now you're ready to start collecting your waste
1. Once your container is full, arrange the first drop-off with your host
1. Voilà, you've made it. Now it's all about creating a routine and making this new wonderful habit stick. Well done!

I have contacted a host and haven't received a reply?
Just be patient and give them a few days. People have lives outside their email inboxes. ;) If they don't reply after a few days, we suggest you simply contact another host in the area.

There are no nearby compost hosts in my area ShareWaste does not manage any composting sites – they are all in private, council or commercial hands – and neither we can register any new sites. Every listing is registered by an individual or an administrator who is responsible for that compost site. If there are no sites near you, it probably means the locals don't know about ShareWaste. There are two things you can do to find yourself a donor soon:

What information do I need to share with the host? ShareWaste is about building relationships. Essentially, hosts don't need to know too much information but don’t forget that they are the ones who open their compost bin or garden to you or who come to greet you at the gate. Having a profile picture, which shows you (rather than, say, a cartoon character) and a real name is the first step to getting a positive reply from a host. Also, talk to your host about what type of waste you produce at home and in what quantities, when would it suit you to deliver the waste and how often.

What does a drop-off look like? The drop-off system can vary from host to host but there are two most common practices our compost hosts have in place:

First, the compost host keeps several spare sealable containers at an accessible place. The donor simply swaps their full container for an empty one, which they then take home. It is up to the host, whether they ask the donors to empty their container into their compost or if they prefer to do this themselves.

Second, the donor delivers their waste in a container or a bag, which they leave at a designated place or which they give to their compost host in person at an arranged time.

In case of community gardens and other community places (council run compost hubs and similar) it depends on their internal rules. Usually they have fixed opening hours and times for drop-offs, e.g. synchronised with the days and times of their working bees.

How should I store my scraps? - Chop up your scraps before storing them (they will take less time to decompose) - Put them in a sealed container – a recycled container with a lid works well (we recommend placing a kitchen towel or two on the bottom to absorb moisture) - Store them in fridge, freezer or shady place outside (e.g. balcony) - Add some brown material regularly (e.g. shredded brown bags, egg carton, newspaper) to keep nitrogen and carbon in balance (it is also an efficient odour and flies prevention) - Donate your scraps regularly – if you keep scraps in a sunny spot for 3 weeks, they'll start rotting, get mouldy and stinky

How should I deliver my scraps? The way of delivering your regular batch of waste depends on your arrangement with the host and whether they are going to be present at the drop-off or not.

Find a system that will make regular drop-offs easy. A walk or a bike/scooter ride to your host are preferred to driving a car (driving a two tonne car to drop off a bucket of waste would not be very environment-friendly). If you have to drive, make it a part of a bigger trip so the drop-off is not the primary reason why you have to get in your car. A walk with a dog, stroll with your children, on the way to/from school or work are all great opportunities to swing by your host with a fresh delivery.

What shall I use to deliver my waste in?

Sealable container

A good way to store your scraps is a sealable container. Such a container gets emptied at every drop-off and can be reused over and over. Some hosts have a system where the donor brings their full container, leaves it on the porch or empties it directly in the compost bin and takes a spare empty one to take home, which the host keeps in an accessible spot.

A single use bag

Donors who don't deliver their waste in a reusable container may choose between (brown) paper bags and single use compostable bags. Brown bags are easy to compost but their major pitfall is that they don't last long and leak if the content is wet. Compostable bags can be used as long as they are truly compostable (not only biodegradable) and suitable for home composting (i.e., not just commercial composting). Always discuss with your host what is the best way to deliver your scraps in advance to find a suitable and convenient solution.

My compost host can't accept any waste at the moment/went on holiday/moved away etc. The best way to be ready for this situation is to have an extra host you can always donate your waste to. Rotating hosts is recommended (you also get to meet more nice people this way!). Always keep your host informed about what is happening. If you decide to change hosts or go on a longer holiday, be responsible and inform your host.

May I ask my host for some finished compost or worm juice? Some compost hosts offer finished compost, some don’t. It depends on the size of their composting system, their garden and how they plan to use the resulting product. If you have been already contributing to a compost host for a while and have a nice relationship with them, it is ok to ask them for some finished compost. Just be aware that composting takes time. In summer, when the process is faster, it takes about 3 months (but usually longer, depends on the type of the composting system, the organic matter and temperature). In cooler months and regions it can take anything from 6 months up to a year. So be patient.

7 For community gardens and other community places

How can we register a community garden? Sign up as a host and select “community garden” type when adding the new listing (don’t worry if you make a mistake and select a wrong type, e.g. “individual” - you can always change it later on the listing settings page).

Who can register as a community garden? In general, all city farms, community gardens and places with similar function as community gardens can register as community gardens. One of the conditions is that the place is open to general public and managed by a local council or community.

8 For cafes

Why should we register our cafe? Hospitality businesses produce large amounts of organic waste (including food waste) every day. If the waste is not recycled in a commercial composting facility, it contributes to landfill, loss of valuable resources and methane production - all of which affects climate change.

How does ShareWaste work in cafes? Registering a cafe or another hospitality business is an opportunity to start distributing the waste it produces to local farmers and gardeners and building connections with the local community. It can also be good for business - customers love to get their coffee and meal from a venue they know to be environmentally friendly.

The key to success is to motivate and educate the staff to separate suitable organic waste for recycling. The best way to do so is by separating compostable items into sealable containers, which can be regularly collected by local community members (compost hosts) who will collect the waste and recycle it in their compost bins or feed it to their farm animals.

How to start:

  • Talk to your staff before introducing any changes. Having the staff on your side is the first key to a successful positive change. Explain why they should care.
  • Register your business on ShareWaste Spread the word on social media, let your customers know and promote it publicly in your cafe to attract waste receivers.
  • Introduce a suitable separation, storage and pick-up system based on discussions with the interested compost hosts. We recommend a system of several sealable containers, which the donors can swap for empty ones. These containers can be kept at the back of the cafe or anywhere convenient in the shade to be easily accessible for the compost hosts or the staff.
  • Adjust the system to the needs of particular compost hosts and add carbon material if possible (such as, shredded egg cartons, brown bags, shredded newspaper)
  • Discuss the waste pick-up process with the compost hosts

How to attract and retain hosts:

  • Be a good partner and make things easy for the compost hosts: offer a free waste delivery if they are happy to take larger amounts of waste.
  • Become a place the host will always be happy to visit: why not make them a complimentary coffee when they come to collect a regular batch of food waste

9 Composting, worm-farming, animal feeding

What items can I collect and bring to a compost host? There are some general recommendations but it always depends on several factors, such as who will accept your scraps or whether they have a composter, worm farm, chickens or other animals. Please always check with your compost host before bringing them the first batch. Also, please

always check the local laws and regulations regarding waste management, composting and/or feeding farm animals.

Compost bin

In general, most people will accept fruit and veggie scraps, tea bags, coffee grounds and filters, egg shells, spent grain, dry leaves, tissue paper, peanut shells, wood ashes, withered flowers, shredded newspaper or cardboard, shredded cardboard egg cartons, wood shavings, grass clippings, cotton pads and other items.

People won’t usually accept meat, dairy, bread and pasta, as these attract vermin and in some countries it may be prohibited by law to compost meat or processed food. Dog and cat droppings is also a no-no for most people (they may contain parasites or diseases). Most compost owners won’t accept glossy paper as it takes a long time to break down and might contain heavy metals. Some compost hosts also accept bokashi or other types of fermented waste.

Worm farm

In general, most worm farmers won’t accept citrus peels, onions and garlic (worms don’t like those). They also probably won’t accept dairy products, meat, bones or anything greasy. Worm food needs to be cut up so that the worms can easily process it.


Bokashi is a Japanese method of recycling organic waste by adding bacteria during an anaerobic process of fermentation. The final product of the bokashi method is fermented waste and bokashi juice. The juice can be used diluted as garden fertiliser whereas the waste should be buried underground, e.g. in an unused vegetable patch, or composted. The bokashi method is often used by apartment dwellers who collect their kitchen waste in a bokashi bucket. Many of them don't have an access to a garden a for that reason they contact compost hosts to find a place to dispose of their fermented waste. Bokashi waste can have quite strong sour odour but it is full of nutrients and many gardeners claim it breaks down faster in compost/soil than unprocessed food scraps. Some ShareWaste hosts accept bokashi and some don’t.

Chickens Most chicken keepers will be grateful for egg shells and vegetarian food scraps (not mouldy or decomposing), excluding: potatoes and potato peels, avocado and avocado peels, onion, garlic, citrus, rhubarb (all these items are poisonous for chickens!). Please always check the local legislation on feeding farm animals: in some countries it is illegal to feed meat by-products to chickens and other animals.
