Biomethane: new development horizons for waste treatment
Tonello Energie carefully valorises and manages the entire waste cycle, starting from the selection and separation phases and proceeding with the treatments necessary for the recycling of the main components. The work of Tonello Energie, however, does not end with the separation phases, but continues with the production of energy directly from the organic component of the waste, using processes of aerobic and anaerobic digestion. Organic waste can therefore be used to produce energy in a green way, thanks to biomethane and compost. These, in fact, are the missing link that allows you to close the chain of "Circular Economy", a path that has long been suggested by the European Union and other major environmental bodies worldwide in the field of sustainable development and that Tonello Energie has chosen to follow. As the term itself shows, we try to eliminate from the equation the term "waste", preferring instead the path of recycling, identifying in each component an added value and a possibility of future reuse. Renewable natural gas, or biomethane, is a type of methane obtained from the decomposition of organic materials of recyclable waste, such as food waste (FORSU), agriculture, SOA and wastewater treatment plants.
Biomethane is an important contribution to the transition from a fossil fuel economy to a more sustainable one. Subject to a purification process, it has the same characteristics as methane, complies with the technical regulations of the sector and is suitable for the subsequent compression phase for the injection of natural gas into the network or distributed directly for transport. The two processes for the treatment of organic waste proposed by Tonello Energie are anaerobic digestion and composting. The first generates biogas, which undergoes an upgrading process that involves the removal of carbon dioxide and harmful elements. At the end of the process there is the biomethane, which can be used for the production of thermal and electrical energy. The waste material from anaerobic digestion is processed and transformed into high quality compost that can be used for soil fertilization instead of chemical fertilizers. Biomethane is an important advantage for:
- the territory: it allows a significant reduction in the volumes of waste sent to landfill
- the environment: since CO2 has been eliminated during the upgrading process, this fuel reduces carbon dioxide emissions into the atmosphere and, unlike other renewable energy sources, its production can be controlled as needed.
- the economy: biomethane allows to reduce the public expenditure for the purchase of natural gas, giving the possibility to invest national resources in an optimal way. At the local level, on the other hand, it allows to reduce the volumes of urban waste, improving the health of citizens and the quality of the surrounding environment.
Tonello Energie follows the customer in all phases, indicating the structure and platforms best suited to its needs and its situation, without overshadowing the needs of the environment. For the treatment of waste, Tonello Energie is inspired by the "Integrated Platform" which provides flexibility, modularity and scalability, three important aspects that allow optimal management of waste, giving the possibility to recycle and reuse larger and larger quantities of waste.
