Credit: Cornerstone Environmental Group Leading the charge in anaerobic digestion... Cornerstone and its parent company Tetra Tech were recently mentioned in MSW Magazine as the leaders in the anaerobic digester project planning with an emphasis on RNG systems. Written by Daniel P. Duffy, "Waste In, Energy Out: The Costs and Benefits of Anaerobic Digesters", the article focuses on the economic benefits of anaerobic digestion technology. In the article, Duffy focuses on two of Cornerstone's RNG projects. Clean World Partners’ Sacramento South Area Transfer Station’s Organic Waste Recycling Center, in which Atlas Disposal trucks bring material to a food waste digester, then fill up their trucks with BioCNG vehicle fuel. As well as South San Francisco Scavenger Company’s (SSFSC’s) Blueline Transfer Station, which will use biogas from food and green waste to fuel SSFSC’s fleet of collection trucks.

Options for increasing landfill densities and compaction are huge game changers, as are government-mandated waste diversion and waste ban policies. Zero waste programs, commodity pricing, waste-to-energy and CNG fuel options, as well as other regulatory changes are expected to change how the industry does business in the next decade.   Read the full article on WasteDive ___________________________________________________________________________
