Anaerobic Digestion

While AD technologies are mature in Europe, the application to North America differs. Learn about the three main types of AD technologies and their applicability, and expected outcomes. Hear lessons learned from Lystek’s food waste digestion pilot project at Goleta Sanitary District Water Resource Recovery Facility. This project uses innovative mobile units for testing and education combining depackaging, anaerobic digestion and thermal hydrolysis.
