The organic waste, after having been collected and transported to the facility, undergoes a selection process to eliminate any non-degradable residues. It is then transferred into special containers, the digestors, where the waste decomposes, producing biogas. This gas is purified by means of special biofilters and then piped into the national natural gas grid.
The solid residue from this digestion phase undergoes further processing: it will be mixed with the less processed parts of wood, known as ‘lignocellulose structurant’, and subjected to the injection of air, a process referred to as ‘insufflation’. From this process comes a high-quality compost that is certified in compliance with Italian law.
