About this good practice
The company KERNEL EXPORT has built a digester to treat anaerobically their wastes. KERNEL EXPORT is a big company that produces, packages and distributes fruits and vegetables from the Murcia Region for all the Europe. This process needs the application of a cold treatment which requires a high energy consumption, indeed this is the most costly production factor.

Moreover the digestato is concentrated and they get a compost of good qualities as fertilizer and which is applied in their own farmlands.
This process is an example of complete circular economy.
