The disposal of some waste such as:
• sewage sludge, of both organic and inorganic matrix
• wet fraction of waste coming from canteens, restaurants, supermarkets, etc.
• waste from agri-food production
• cultivation waste
it constitutes an important expense item in the company balance sheet, with costs destined to grow over the years due to increasingly stringent industry regulations.
The presence of water in high quantities in these wastes – although variable according to the specificity of the process that generated the matrix – suggests the opportunity to remove this water. This allows to obtain a substantial reduction of the volumes disposed of or, in some cases, the possibility of re-use of the material obtained, providing for the recovery of material and / or energy.
This obviously requires the optimized use of energy (both electrical and / or thermal) to allow evaporation.
Equally important is to ensure an appropriate stabilization of the product obtained, in order to avoid the generation of odors, an aspect that is one of the most critical elements in the management of organic matrices.
All this at investment and management costs that ensure a quick return on the coherent investment and with maximum simplification of the authorization procedures.
