The activity based on private capital of Gruppo Serramanna Energia Spa consists in the production of electric energy from renewable energy sources, and in particular from solid biomass.
The power plant, located in Sardinia, in the province of Mediocampidano, eligible to the national incentive program for a period of 20 years, started its first parallel-grid in October 2009 and after a trial period, this became fully operative in 2010.

The activities of Gruppo Serramanna Energia Spa cover multiple fields of the biomass sector. In fact, the Groups stocks up in Italy and abroad, whether directly with its own means and forest operators, and also through a selected number of suppliers who provide finished products to the plant.
The Group’s activities also developed in the agro-energy culture sector, experimenting the most suitable cultures with the best outputs.

Renewable sources are mainly of local origin, and in order to ensure specific average calories in the combustion process, part of them comes from a few tropical countries and from the Mediterranean basin. These sources consist of wooden chips, made of virgin vegetable materials of multiple origin, and boasting the characteristics imposed by the most recent applicable laws, among which silviculture recycled materials, wood chips, maintenance of rural vegetation, maintenance of fireguard areas, agroindustrial recycled material like marc, artichoke stalk, pruning of olive cultivations, olive residues with and without seed, Palm kernel and almond shells and specific cultivations on marginal land unsuitable for food crops.

Our values are based on a shared, dynamic and responsible approach to do business, which combines economic, environmental and social sustainability.

A clear example of social commitment by the Group can be seen from the description of the project in Guinea Bissau, which aims at improving the economic conditions of some villages by supplying machinery to perform production and sale activities of bio-fuels, using palm oil and seed discards (PKS, Palm Kernel Shell) obtained by recycling and transforming production residues. The project was born from the meeting of different stakeholder who deal with the same vegetable product, the PKS, even if with different goals. The stakeholders are Programma Sviluppo 76, the DICAT department of Genoa University, the local partner Amigos da Guiné-Bissau, the Belgian ONG Codeart and company Sardinia Bio Energy.

Gruppo Sardinia Bio Energy, in addition to collaborate with Programma Sviluppo 76 to activate the project in Guinea Bissau, has constantly shown its interests also in purchasing PKS from operators in Guinea Bissau.
The association-enterprise relation aims at an equal economic development that includes profit and non-profit stakeholders, it places the beneficiaries at the same level of donors, and provides them the tools for sustainability. The new established relation turns cooperation into a partnership and no longer as an assistance service.
