Anaerobic Digestion processes food waste and converts it into energy and fertiliser. It avoids adding food waste to landfill and saves fossil fuels. it uses bagged food waste such as fruit, vegetables, meat and fish, dairy, perishables, liquid food waste and grease trap contents.
Benefits of using AD bags made from Hydropol™:
EarthPower Technologies is a joint venture between Cleanaway and
Veolia. They convert organic waste material from the industrial, commercial and residential sectors into green energy and nutrient-rich fertiliser.
They filled hot water soluble AD bags made from Hydropol™ and filled them with food waste. This contained the typical organic waste of their customers such as fruit and vegetables, meat and fish, diary, perishables, confectionery and grease trap contents. They also filled one Hydropol™ bag with 12 empty Hydropol™ bags.
The filled bags were put into EarthPower’s Hydro pulper via a pulper screw conveyor. The food waste and Hydropol™ bags were processed in their industrial blender, being pulped with warm water at approximately 45 degrees Centigrade for 10 minutes.
The contents of the pulper was then washed and discharged. As seen in the image below, during examination traditional plastics were still evident however, there were no remains of the Hydropol™ bags.
