Biomethane from municipal waste

The Organic Fraction of Municipal Solid Wastes (OFMSW) can be processed in industrial anaerobic digesters to produce biogas. The upgrading of the biogas produces the biomethane which, after compression,
can be used as vehicles fuel.
An interesting integrated solution is the utilization of the biomethane for the filling of the municipal or the multi-utilities fleet of vehicles dedicated to the collection of the municipal wastes.

Biomethane from food industry wastes and wastewater treatment sludge

The food industry produces important amounts of organic residues including sewage and slaughtering waste. Typical residues are blood, skin, bones, and entrails from the slaughter-houses and waste from the fishing industry. These biomasses, which are rich in proteins and fats,
are an excellent feed for the anaerobic digesters. The agri-food sector produces enormous amounts of waste and organic residues suitable for the anaerobic digesters. Among them the most utilized are the whey from dairy factories,
which is rich in sugars and proteins; the waste from fruit juices industry, from distilleries and oil production mills. The sludge from the treatment of municipal and industrial wastewater is composed by organic biomass mixed with organic and inorganic inert mass.
The main targets to feed the anaerobic digesters with the wastewater sludge, which yield is rather low, are the stabilization of the organic matrix and the reduction of bacteria content in order to enable a final safe disposal.

Biomethane from agricultural by-products and from sewage

All the agri-livestock industries are producing enormous amounts of by-products which can be profitably used to feed the anaerobic digesters.
An interesting way to close the circular production loop is upgrading the biogas to biomethane for fueling the farm vehicles fleet.

Carbon Dioxide (CO2) for the algae growing

Algae, especially the micro algae, are the new generation source of biofuels like biodiesel and biomethane. The growing of algae depends on the availability of CO2 during the photosynthesis process.
By utilizing the GM upgrading unit it is possible to upgrade the biogas to biome thane and to enhance the algae growing by the total recovery and reutilization of CO2 removed from the biogas.
