The Italian town of Caravaggio, South of Bergamo, offers a 20% waste collection tax rebate for households that have installed a food waste disposer discharging directly into the municipal sewer system.

And in the Macerata province, a field trial was carried out in the mountain village of Gagliole installing FWDs in homes and a school for 67% of the 250 population. The ease of capture of uncontaminated food waste was found to be cost effective in contrast to the high costs of food waste collection and transport to treatment.

Researchers found no problems in sewers, a benefit to wastewater treatment, an increase in biogas production for heat, electricity and fuel, and a payback to the community of only 4-5 years.
