Why is it so important to extract as much biogas as possible from waste?
Amid the current energy source crisis, it is essential to find an alternative resource base.
Biogas, which has been extracted from organic residues for several years now, is a mixture of methane, carbon dioxide, and other substances from which clean energy can be produced.
It is extracted from waste using conventional methods, that is, by hand and in an inefficient, non-uniform way that is also weather sensitive.
According to data provided by the ISPRA (Higher Institute for Environmental Protection and Research) – Environmental Data Yearbook 2019, No. 89/2020 – landfills are the second largest source of methane emissions into the atmosphere, accounting for nearly one third of all identified sources. In order to optimise the capture of biogas and energy recovery, it is necessary to reduce the ecological footprint and improve air quality and, in doing so, obtain renewable energy from waste.
We need to rethink renewable energy sources in the area in order to produce energy locally and thus reduce transport and supply costs.
More energy and less odour: the case of the Fano landfill
ASET Servizi is the number one user in the world of the innovative Gas Stabiliser technology. At the Monteschiantello landfill in Fano (in the province of Pesaro-Urbino), a 32% increase in the total amount of gas ‘captured’ and sent for energy recovery was achieved.
A special algorithm allows for not only automated remote control and optimised extraction with the added benefit of preventing the spread of odours (emissions into the atmosphere), thereby avoiding fire and explosion risks at storage sites, but also – as the spokesperson for ASET S.p.A. Servizi explains – ‘the adoption of innovative systems such as that of Zero3, which can prevent gas from being released into the atmosphere, turning it into a raw material to produce clean energy. In fact, biogas is made up of 50-60% methane, a greenhouse gas that experts believe is 80 times more polluting than carbon dioxide. Given the current energy crisis, it is worth pointing out that Gas Stabilizer consumes 10 times less than similar plants.’
Gas Stabilizer
Innovative automation system for biogas collection that optimizes the performance of traditional collection systems by increasing extraction efficiency.
• It enables continuous remote monitoring and control, in real time, for each collection line
• It is modular, can be dismantled and can be applied to any type of biogas collection plant, both new and existing
