Circular Biocarbon

Project description

CIRCULAR BIOCARBON is a first-of-its-kind flagship biorefinery conceived to valorise organic fraction of municipal solid waste (OFMSW) into value-added products: diamond-like-carbon coatings, green graphene, tailor-made bio-based fertilisers, or bio-plastic, as well as a variety of intermediate products. In order to maximise replicability and boost potential penetration in the market, the biorefinery will be operated for three years in Spain and Italy, and consistent business and exploitation strategies will be put in place. The CIRCULAR BIOCARBON biorefinery, organised through a pool of cascading technologies, start from anaerobic process steps (after proper pretreatment) of mixed urban waste streams, of which OFMSW is the main one, in order to treat all the biowaste produced by a medium-size city (at the end of the project, a commercial scale biorefinery will be fully operative). The fundamental objective of the CIRCULAR BIOCARBON project is to open up new business frameworks based on a new circular vision of waste treatment in a city towards a sustainable bioeconomy, to which actors leading the territorial waste management schemes and policies will be brought to maximize impact on the market, on policy makers and on society.

Measured, quantitative outcomes / project impact

The CIRCULAR BIOCARBON project is aimed at delivering a number of impacts that will contribute to the wider goals of the BBI-JU. These will include: • Creating up to seven new cross-sector interconnections between the waste management, water utilities, coatings, electronics, chemical, bioplastics and agriculture sectors. • Establishing four new bio-based value chains from the organic fraction of municipal solid waste and sewage sludge. • Producing nine new chemical building blocks based on the organic fraction of municipal solid waste and sewage sludge. • Developing four new bio-based materials. • Demonstrating seven new consumer-oriented products, including decorative coatings, biodegradable and compostable waste bags, biodegradable in soil mulch films, microalgae bio-stimulant liquid fertiliser, solid organ-mineral fertiliser with biostimulant properties, green night vision cameras and green photonic devices for 5G telecom technology.
