Towards a revolution in the valorization of bio-waste
The SCALIBUR (acronym for Scalable Technologies for Bio-Urban waste Recovery) project, comprised 21 partners from 8 European countries of different scope (research centers, universities, local government, waste managers and companies) among which is Aeris Tecnologías Ambientales S.L. After more than four years of intense work, the project has allowed to take a substantial step forward in the transition towards a circular economy in Europe, increasing the technological viability and the industrial applicability in the field of urban organic waste recovery through strategic cooperation between various sectors.
SCALIBUR contributes to two European challenges: reducing landfills and achieving a circular economy by 2030. SCALIBUR has presented an innovative concept for the recovery of three important sources of organic waste: the organic fraction of municipal solid waste collected selectively, organic waste from the HORECA channel and supermarkets and sewage sludge from urban wastewater treatment plants. From these residues bioproducts of high added value have been obtained.
Aeris Tecnologías Ambientales S.L. has been the entity in charge of validating and demonstrating the production of biopesticides using the Solid State Fermentation (SSF) process from the solid fraction obtained by the enzymatic hydrolysis of the organic fraction of municipal solid waste. In collaboration with the GICOM Group of the Universitat Autònoma de Barcelona, laboratory-scale tests have been carried out to optimize the operating conditions in terms of temperature, aeration, homogenization, etc. and thus maximize the production of this biopesticide. These tests will be the basis for the subsequent upscaling of the process.
