Resumen
Anaerobic digestion (AD) of organic matter is a robust technology for biogas synthesis from
different types of waste
(sewage sludge from water treatment, animal slurry, bio-waste, etc.). The main goal of AD is the
production of methane, a renewable energy source that can be used to generate electricity, heat or
as vehicle fuel. Biogas is a mixture of methane (CH4; 55-70% of the total volume), carbon dioxide
(C02; 30-40%) and traces of other gases. In 2018,
EU was the world's largest producer of biomethane, reaching 2,28 bcm. However, from a purely
engineering view, the microbial process underlying methane production is considered to be a black
box: it is subjected to a degree of variability and it is an industrial process with a lot of room
for improvement in the systematic optimisation of (1) yield, (2) quality, (3) speed and (4)
robustness of the process.
MICR04BI0GAS aims to tackle these 4 aspects by integrating, for the first time, the use of
microbial consortia that naturally inhabit anaerobic digesters with synthetic microbial consortia
with improved capabilities, setting the basis for a user-friendly kit for bioaugmentation of biogas
production (activities will be implemented at TRL3 with a TRL target of 5-6).
