Exergy present feasible and cost-effective solutions to produce bioelectricity through microbial fuel cells


Exergy participates in the Agrocycle project which is addressing a wide range of valorisation pathways for agriculture using a circular economy approach, including bio-fuels, high value-added biopolymers, wastewater treatment and microbial fuel cells, among others.

For this project, Exergy is in charge of the demonstration of the technical feasibility of the pyrolysis of forestry residues and the production of bioelectricity by means of Microbial Fuel Cells (MFC), as well as leading the overall biofuels’ production activity where biobutanol, bioethanol, and biogas are also produced.

At the month 18 General Assembly meeting held in Brussels on October 18th, Rocio Roldan and Sara Monasterio, from the Sustainable Processes Department at Exergy, presented the general overview of the actions carried out in terms of biofuels’ production. The MFC activity progress was presented and compared with related activities developed in parallel in Nanjing Uni in China. Exergy showed a feasible and cost-effective solution which has been engineered and designed to produce electricity at a small scale from wastewater treatment activities related to the agri-food waste processing sector.
The MFC results, according to the consortium, “seem to be promising considering the narrow timeframe of the Agrocycle project.”
During the same week, the Agri-Food Waste Day Conference was held on October 17th in Brussels. The conference was a joint initiative between the European projects Agrocycle and No AgroWaste, both of them funded under the same topic Waste-7-2015, with the aim to present current thinking and developments in relation to the Circular Economy applied across the agri-food industry. Different technologies and approaches were presented for the valorisation of agri-food waste in high-value intermediate and final products: biogas, digestate, biomethane, biohythane, bio-oil, bioethanol, biobutanol, syngas, bio-oil, bioethanol, biochar, building blocks, biopolymers, lignocell filters, composites and other chemicals, biofertilisers, nutraceutical, pharma products, wastewater technologies, animal feedstock and bioenergy, where some of them are common in both projects addressed by different technologies. The conference also had a strong focus on the business opportunities around the technologies. A wide range of different stakeholders and organisations both internal and external participated in the event including partners from China and Taiwan.
