Diverting Organics From Solid Waste to Regional Wastewater Treatment Plants for Anaerobic Digestion and Renewable Fuel Generation

The South Bayside Waste Management Authority (SBWMA), also known as ReThinkWaste, already had a high landfill diversion rate—over 50%–but recognized there was room to increase its organics diversion. To support municipalities striving to comply with California’s new requirement to divert 75% of organic waste from landfills by 2025, ReThinkWaste needed a system that was up to the challenge of recovering organic material from source separated organics and solid waste streams. They selected a turnkey Anaergia solid waste processing line to add to their main transfer station and recycling facility. The line includes Anaergia’s proprietary OREX® organics extrusion technology as well as bag opening, shredding, and Organics Polishing Systems.
