Mass and Energy Conservation

The corporate policy of Sostenya Group is then to promote the continuous development and adoption of innovative solutions, in strict collaboration with partners that are able to provide the most advanced technologies available on the market. We are active in this field through one of our subsidiary.


Waste and Organics: Two Sources of Clean Fuels

We believe in the close correlation and synergy between the Environment and Renewable Energy. Through the subsidiaries operating in the environmental sector, Waste Italia extended the concept of waste recovery. Waste to Energy is the process of generating energy from the primary treatment of waste in order to produce biogas, a "green fuel” that can be used to produce electricity and heat.


  • Primary energy resources saved;
  • To avoid the production of greenhouse gas generated by power plants that use fossil fuels;
  • to reduce the number of landfills.

In the case of unselected waste in landfills, the natural degradation process produces gases that are captured, cleaned and burned in dedicated engines in order to produce energy that is locally used to satisfy landfill needs. Food and garden waste (from agro-food industry, farm residual, animal manure) are collected, selected and treated in anaerobic digesters.
The anaerobic digestion is the breakdown of organic materials into methane and carbon dioxide gas; actually, Biogas is the name given to the mixture of gas formed during the anaerobic digestion of organic wastes.
Anaerobic digestion allows the production of a clean energy and has a positive impact on local agriculture and recycling waste. Sostenya Group has a strong record of accomplishment in biogas both from landfills plants and from anaerobic digestion plants in Europe and worldwide through projects and collaborations with dozens of plants designed, constructed and managed.

Bio Methane

Sostenya Group is making a special effort to developing technology to developing new technologies and switch biogas with bio-methane. Bio-methane is produced from “fresh” organic matter; it has a number of environmental benefits, which make it a green source of energy. Bio-methane production eliminates the release of a great deal of methane and other harmful gases into the atmosphere.
This is because its production eliminates exposure of the decomposing organic matter to the air that prevents methane and other gases from escaping into the atmosphere. 

Since bio-methane is chemically identical to natural gas, it can be used for the same applications as natural gas. It can be used for electricity generation, water heating, space heating, cooking as well as to fuel vehicles. Bio-methane offers great potential as an alternative source of energy, especially to fossil fuels.
