Urbiofin

Problem statement

Demonstration of an integrated innovative biorefinery for the transformation of Municipal Solid Waste (MSW) into new biobased products.

Executive summary

URBIOFIN exploits organic urban waste as a raw material according to its nature and composition. To this end, it will define the industrial requirements necessary for the transformation of waste into new bioproducts and the interconnection between them in order to achieve synergies that lead to a versatile and efficient biorefinery.

Value chain description

The organic fraction of urban MSW mainly contains carbohydrates, proteins and lipids, which are all useful raw materials that was converted to valuable products. Its valorization has helped to solve environmental pollution, and also contribute to the transition from a linear to a renewable circular economy. Digestion and composting have contributed to the reduction of the biodegradable fraction of MSW sent to landfill. However, the low economic value of compost and biogas has limited the sustainable implementation of separate sourcing systems. Therefore, the aim of URBIOFIN project was to demonstrate the technoeconomic and environmental feasibility of the conversion at semi-industrial scale of the organic fraction of MSW into: Chemical building blocks (bioethanol, volatile fatty acids, biogas), biopolymers (polyhydroyalkanoate and biocomposites) or additives (bioethylene, microalgae hydrolisated for biofertilisers) which are marketable products for different markets like agriculture and cosmetics. The overall results of this project can be summarized as follows a) Successfully demonstrated conversion of municipal solid waste into bioethanol and bio-ethylene for value added market applications b) They have shown sustainable technologies for combining AD and other fermentation technologies for a new generation of biopolymers aimed at cosmetic and agricultural applications c) Also exhibited PHA production from biogas in wastewater treatment facilities which have helped them to develop Integrated innovative biorefinery for the transformation of municipal solid waste into biobased products, bioenergy and biopolymers.
