# Reward4Waste

> Reward4Waste is a blockchain-based incentive system for glass recycling that rewards consumers with digital tokens for returning glass bottles. The system uses IoT sensors and QR codes to register returned bottles and transparently documents the entire recycling cycle on the blockchain. A pilot project in Ireland achieved a 94 percent return rate, demonstrating the potential for higher recycling rates through digital incentives.

## Description

RE:Universe developed Reward4Waste as a token-based incentive system for recycling. The basic principle: users download the app, go to a glass or packaging container, scan a QR code before depositing, and confirm the action. The blockchain immutably records the recycling activity — tokens are only awarded for verified actions.

The core problem with recycling incentives: how do you prove that someone actually deposited glass? Reward4Waste solves this through a combination of geolocation (the user must be at the container), QR code scanning (each container has a unique code), and app confirmation. The blockchain ensures that a deposit cannot be rewarded multiple times and that tokens are only issued for genuine recycling activities. Earned tokens can be exchanged for vouchers, products, or experiences. For manufacturers and retailers, the system provides valuable data: which containers are used, by which target groups, at what times — directly usable for sustainability reports and optimisation of container placement. The concept follows the successful model of Plastic Bank (plastic collection tokens in developing countries) and is adapted for the German market. Germany has one of the highest glass recycling rates worldwide at around 84% — token incentives can further improve purity (sorting) and participation of younger target groups.

## Benefits

- Companies can reduce their raw material costs through greater availability of recycled glass while simultaneously achieving sustainability goals.
- Consumers receive direct financial incentives for environmentally conscious behaviour through redeemable tokens.
- The system can significantly increase the glass recycling rate, as demonstrated by the Irish pilot project with a 94 percent return rate.
- The blockchain documentation creates complete transparency over the entire recycling cycle.
- Token-based incentives motivate consumers towards more sustainable behaviour and strengthen the circular economy.
- Employees benefit from automated processes that reduce physically demanding sorting tasks.

## Challenges

- Companies must adapt existing logistics and management systems to the new blockchain-based infrastructure.
- Implementation requires significant investments in IoT infrastructure and the development of a functioning token ecosystem.
- Integrating various stakeholders from consumers to recycling companies is complex and time-consuming.
- Employees need training to handle new digital technologies and changed workflows.

## Technology foundation

The system is based on blockchain technology for secure and transparent documentation of all recycling transactions. The blockchain is particularly suitable for this use case as it enables immutable records over the entire cycle from collection to recycling.
