Organics-to-Energy technologies convert source-separated organic materials into electricity and/or thermal energy without direct combustion. Depending on the type of system, additional useful outputs may be produced, such as liquid fertilizer or compost.
The benefits of organics-to-energy facilities can include:
Anaerobic digestion is one example of an organics-to-energy technology. In an anaerobic digester, microorganisms break down organic material in the absence of oxygen to produce methane. The methane can then be used to generate heat or electricity.
Another example of an organics-to-energy technology is composting with heat recovery.
Anaerobic digestion is currently used at several sites in Massachusetts, including farms, food processors, and wastewater treatment plants.
MassCEC supports the development of projects employing these technologies through the Commonwealth Organics-to-Energy program.
