The plants for the disposal of urban, industrial, zootechnical and agroforestry waste have two common objectives:
– transform waste into a resource
– protect the environment from degradation due to the abandonment or incorrect use of waste
The economic question related to the plants is one of the problems encountered in the first approach with customers. A waste treatment plant must in any case be supported by a cost-benefit analysis that justifies its implementation. This depends on the site’s environmental, economic, legislative and cultural factors. Our staff provides context analysis in order to give adequate solutions to the problem.
An important distinction must be made based on the material to be treated.
For organic waste with an adequate moisture content, the recommended technology is anaerobic digestion through biogas plants. They differ from biomass plants because they act by natural fermentation and not by combustion, they do not emit toxic substances into the environment and they are the ideal plants for the disposal of most organic waste.
Biogas, generated by the treatment of organic waste, is mainly made up of methane (50-70%) and carbon dioxide. Anaerobic digesters dispose of waste, both liquid and solid, and can generate electricity and thermal energy or alternatively can generate biomethane. The inert material, waste from the anaerobic digestion process, can be used as compost fertilizer.
Everything that is an organic waste now becomes a precious source. Each organic waste has its chemical and physical characteristics and consequently has an energy yield different from the other waste.
If the waste to be treated instead includes materials such as plastic, metal, glass, aluminum, paper and cardboard, fabrics and other, the treatment of waste could vary from the production of fuel from high-energy waste to the separation of materials destined for recycling.
Our expertise in the energy sector allows us to sew systems according to the real needs of the customer and not impose pre-dimensioned technologies or systems to which the customer must adapt their resources.
URBAN SOLID WASTE
The accumulation of waste, many times in open-air dumps, represents a serious problem, both for human health, due to the unhealthiness of these areas, and for the environment, due to excessive CO2 emissions and toxic substances.
Transforming municipal solid waste into energy, economy and well-being for citizens is important for us and for future generations.
ZOOTECHNICAL INDUSTRIES WASTE
The waste from these industries today represents both an economic problem, linked to the cost of waste disposal, and environmental problems due to the emissions of waste thrown into the fields as compost before the fermentation process.
Bovine sewage, pig manure, poultry dejection, slaughter waste and other industrial waste can be a source of corporate wealth.
Production of thermal power, electricity, compost and biomethane
For each MWe of power, a biogas plant produces approximately 4.2 million m3 / year of biogas and the entire digestate can be used as compost fertilizer.
The produced biogas can, through a cogenerator, generate electricity equal to approximately 8.5 million KWh / year and thermal energy equal to about 9 million KWh / year. As an alternative, biogas can be further filtered and generate 2.5 million m3 / year of biomethane.
If we start from a non-differentiated collection, all the non-organic material is properly separated, and prepared for a subsequent life cycle or part of it can be used for the energy enrichment of a suitably produced Waste Fuel.
