AMIU, the plant in the metropolitan city of Bari powered by OFMSW

Owned by AMIU, the municipalised urban hygiene company that manages the waste collection,
processing and disposal activities in the city of Bari (Apulia, Italy), the plant built by BTS Biogas in
2020 has an installed power of 1,200 kW . The site, powered by OFMSW (Organic Fraction of
el
Municipal Solid Waste) mixed with other compostable waste fractions such as pruning cuttings, is
able to produce electrical and thermal energy and soil fertilisers. It is one of the few plants
constructed for the processing of organic waste in a metropolitan city, built to utilise organic waste
and make a virtuous and sustainable waste disposal system available to citizens.
The project involves AMIU collecting and transporting waste to the plant’s delivery areas, where the
quality of the biomass is assessed: that which is not considered suitable is discarded. The plant is
able to produce electricity or heat for self-consumption, with the surplus being sent into the
network.

Demeter Energies, the French plant powered by farm effluents

The Mauzé-sur-le-Mignon plant (France) was built by BTS Biogas in 2016 for Demeter Energies,
the capital of which is held by local dairy cattle, beef cattle and goat breeders and cooperatives and
Sergies, the energy union which holds 20%. This initiative was in response to the demand that
requires French farmers to reconsider their production methods and diversify them to keep the
sector alive.
The plant, with a capacity of 499 kW , is able of processing the effluents of 12 farms located within
el
a radius of less than 8 km, converting them into electricity, heat and natural fertiliser.
The surplus, which corresponds to 1,500 MWh, is channelled into the heating network built by
Demeter Energies in Mauzé-sur-le-Mignone and used by public buildings, saving the equivalent of
15 tonnes of gas for the René Caillié secondary school, 115,800 litres of fuel for the swimming pool
and municipal buildings and 135,000 litres of fuel for the corn and alfalfa dryers. The electricity
produced meets the domestic needs of around 1,300 people. Mauzé-sur-le-Mignon was one of the
first French cities with fewer than 10,000 inhabitants to produce heat and energy from renewable
sources.
