Map to make a Difference

Has the trash near you been mapped yet? No? 
Go out mapping and make a difference! Here’s how.

1. Take picture, choose size

2. Mark type of trash you see

3. Choose accessibility, add note. App ads GPS location.

4. Dump is located

Frequently Asked Questions

Waste mapping gives ground to start finding solutions to a problem where polluting reoccurs. Furthermore, visualizing all the world’s waste together in one platform helps to see a bigger picture of how big the problem actually is.

Mapping can be done all around the year to collect data for a change.

When you coordinate a mapping event then be aware that safety regulations are different in different countries worldwide.

    • Make sure to check with your local government and police if making group events or/and making photographs are allowed in your area.
    • See that mappers are well-hydrated and that area is safe for them. When in doubt, ask them to go out in pairs or groups. Check that kids are not left unattended.
    • Check that you have a basic First Aid Kit with you.
    • Make sure you know the emergency contacts before starting the activity.

The goal is to get all the waste that does not fall under the scope of regular collection services picked up. When mapping for World Cleanup Day the common rule is – map it if you cannot pick it up.

    • Maximum amount: In app, the maximum amount is a “Car needed”. If the waste is scattered around in wider area we recommend to create several trashpoints.
    • Minimum amount: “Fits in a bag” could be used for smaller trash piles. We recommend to clean litter up immediately and not to map it.

Trashout mobile app is available in English, Slovak, Czech, Russian, Spanish, German, French, Italian. Adding additional languages requires certain time and financial resources for implementation. Typically new language is translated by volunteers. If you wish to know conditions and process of adding new language please contact us through: [email protected].

Once we have enough data, we can move forward to questions like: Where is the waste located? What kind of waste? Where could it have come from? That’s why it’s also important to add correct and detailed information when you create a trashpoint. We will model and analyze the data, using rigorous science, to determine the answers to these questions, and subsequently define proposals and strategies to tackle the problem globally, and in every specific situation.

Adding a trashpoint to the map may seem like a small thing, but it is actually also data collection through citizen science (also a community or crowd-sourced science). Citizen science means that everybody can engage in research activities and work side by side with experts, addressing local, national and international issues that need scientific support. By adding a trash point to the map you are contributing with your bit of information to a bigger database.\n\nThere is still very little knowledge about how much mismanaged waste there is, so mapping gives us huge potential to get that data. The more information we have, the better. Every trashpoint counts!

Each mapper should give her/his best to keep the data in good shape. Please add “test” to the Additional Info field of trash points that are not showing real trash. Do not leave any people/car numbers/companies logos (if not included in the trash pile) on the photo. When you choose an area to go mapping, try to do it in a systematic way. Ideally, you should check all dumps reported, then go to the area selected for cleanup and report/update those in the area. Once cleanup is done go through the area again and update dumps as cleaned. This way you will have clear data and proof of your work.

We chose the most common types of waste that can be typically found on illegal dumpsites. If you miss any type of trash you can always add note or let us know.

This makes life of volunteers easier. If it is under water you often need special equipment and same if it is dangerous waste. If there is cleaning event happening for general public it might be safer to choose only those accessible by car.

We require pictures as “proof” of the existence of an illegal dump. The picture should be taken with a mobile phone so we can get exact GPS coordinates of your location thus the location of an illegal dump. Accuracy should be more precise this way, especially when you have a good strength of mobile data and are under a clear sky.

For now you cannot. You can take pictures and report it later via web browser if you go to

Sometimes it can happen that there are more users than we are prepared for, although we are doing our best to fix the situation. First, we advise you to wait a couple of minutes. If the app still does not work then the best is to take a picture of the dump and do a screenshot from the map application (like google maps) from the same place. This way you will always know where the picture was taken and you can add this report later via our web platform from your home.

    • Divide a bigger area into smaller areas!
    • Find a local coordinator to be responsible for each smaller area who can train the users and localize the approach!
    • Localize the materials based on language and culture!
    • Make it fun!
