The careless use of packagings alone results in 32% of the 78 million tonnes of plastic entering the environment (source: WWF). In addition, there are many other non-compostable materials that end up in the oceans, destroying the habitats of animals and plants. Although this problem could be solved by properly collecting, disposing of and recycling waste, there is still too little active willingness in society to do so. There is a lack of easily accessible and state-subsidised resources, tools and incentives that promote collective cooperation and encourage citizens to collect.

With the "Strollect Service", users of different ages can easily borrow the right equipment for litter picking at one station and return it at another. Supported by in-app events organised by local communities or "Strollect" itself, users can make new contacts or meet up with friends to collect rubbish. Each trolley is equipped with two grippers for this purpose. As an additional incentive, the use of the service is rewarded with so-called "Benefit Points", which can be redeemed at regional attractions (e.g. cafés, museums). By collecting your own waste, you can raise your awareness of the sustainable use of resources.
The collected recyclables, which have already been sorted in the trolley by the users through the modular partition walls, are collected by "Strollect" employees with electric transporters. They are then sorted again and passed on to partner companies (like "Terracycle"). The recycled raw materials are used to make spare parts for the trolley and new products.

Furthermore institutions such as research organisations can also benefit from "Strollect" by being able to view the collected data on our website. In this way, conclusions can be drawn about the type of waste and/or major waste producers and the basis for new regulations or laws can be created.
