ABSTRACT
A green economy is an economy that aims to reduce environmental risks and ecological scarcities, and that lines up sustainable development without degrading the environment. Waste can be solid, liquid, or gas and each type has different methods of disposal and management. Since the common principles of management are efficiency and fairness, Blockchain as a peer-to-peer concept with a consensus mechanism is suitable for waste management. The paper presents the first stage of project “Blockchain in solid waste management”. From several points of view a review of solid waste management is performed, in which the blockchain has the major role: (1) problem definition and possible solutions; (2) Blockchain applications in solid waste management; (3) blockchain applications for different solid waste types; (4) blockchain elements for waste management; (5) blockchain in cooperation with other technologies. The author syntheses advanced sorting process, models of Blockchain in solid waste trading, and three use cases with selected granularity. The used design methodology is unified modelling language: activity diagrams and communication diagrams. The author applies the principles of supply and demand. The models are intended for business developers, university professors, and students.
