We value organic waste
With the term “waste”, we think of something related to the problem of disposal, as nowadays it is increasingly difficult to find spaces where to store the enormous quantity of solid urban waste.
Hence the need to transform this problem into a resource by producing renewable energy.
The organic fraction of urban solid waste, slaughterhouse waste, expired food and everything related to nutrition (milk, fish, sweets, etc.), are extremely effective organic matrices for anaerobic digestion.
Mainly these categories of waste were treated in composting plants, today the optimal solution to arrive at a circular economy model is the construction of a biogas / biomethane plant.
Our waste plant
The biogas / biomethane waste plant can only be built if separate collection is carried out.
In addition to the organic fraction, other types of material can be added, such as sewage sludge, agro-zootechnical and agro-industrial by-products, an integrated solution that guarantees to fully exploit the biomass supplied.
Organic waste cannot be treated as it is, consequently it is subjected to a pre-treatment where two basic steps take place:
- the separation and removal of plastics and other aggregates.
- the shredding of the biomass in order to make it as palatable and homogeneous as possible.
Once this process is complete, the material is introduced via the feed system into the digester.
The anaerobic process is carried out under thermophilic conditions (55 °C) to ensure maximum hygienization of the material and increased biogas yield.
Once the biogas reaches the cogenerator, it is transformed into electric energy, which is fed into the national grid or into thermal energy used to keep the process temperature constant and for district heating.
The material resulting from the anaerobic process (digestate) is then stabilised within a bio-oxidation dynamic process, this is an innovative composting process that is characterised by its simplicity and effectiveness, it uses bio-chemical processes that significantly reduce the environmental impact of the process (especially in terms of odour emissions).
The result is the production of a quality compost, which allows to class the digestate as a highly-agronomic quality fertiliser, declassifying it as waste.
