Managing Compostable Bags At Anaerobic Digestion Plants
Figure 3. Amounts (percent by weight) in light fraction after dewatering, manual sorting and chloroform extraction with FT-IR analysis

An analysis was performed in Italy to better understand the interaction of compostable bags with hydropulping pretreatment systems in wet AD facilities. Results show further recovery potential for the residues, with optimization of overall system performance.

Plastic Bag Ban And Residential SSO Diversion
Residential source separated organics service is now available to 24 million people in Italy. In 2010, 2.8 million tons of food scraps were collected for composting and anaerobic digestion.

Italy’s nationwide ban on plastic shopping bags in 2011 exempts compostable bags, which has in turn benefited organics diversion.
