Abstract

The majority of countries are currently struggling to achieve sustainable levels of recycling and waste treatment, particularly relating to household waste, and this area is in urgent need of new solutions. In general, the waste management sector has struggled with low consumer trust, fraud, manipulation, significant manual processes, and low levels of information and control. Here we propose a hybrid blockchain solution called a Polkadot parachain. Polkadot is a blockchain technology that allows for the development of a network of blockchains, each called a parachain that can be customised to the business needs of a given application. This solution provides the cost benefits, scalability, and control of a permissioned blockchain while providing the security, verifiability, and trust of a public blockchain. The solution combines three typically separate blockchain use cases: supply chain tracking, incentivisation through a payment system, and gamification to achieve a complete solution for waste management. We provide a detailed discussion on the design of this blockchain solution with the use of blockchain functionality assessed against the criteria and development approaches found in the literature. Finally, we demonstrate how such a blockchain can be implemented with the Substrate blockchain development framework and detail a pilot project where this system will be implemented.
