The Digest’s 2025 Multi-Slide Guide to converting organic waste to biopower ips

March 6, 2025 | Jim Lane

This presentation by Lutgarde Raskin from the University of Michigan describes a project developing an integrated biochemical and electrochemical technology (IBET) system to reduce the production cost of renewable biomethane by at least 25%. The three components of the system have been built and achieved most of their performance targets. Model and control strategy development […]

The Digest’s 2025 Multi-Slide Guide to High-Performance Anaerobic Membrane Bioreactors for Waste to Energy

March 5, 2025 | Jim Lane

This presentation by Lance Schideman from the University of Illinois at Urbana-Champaign, focuses on a cloth filter anaerobic membrane bioreactor (CFAnMBR) for municipal wastewater treatment. The CFAnMBR technology achieves high flux with low cleaning energy, resolving major limitations of mainstream anaerobic digestion. The system results in net energy production, eliminating aeration needs but requires optimization […]

The Digest’s 2025 Multi-Slide Guide to novel anaerobic digestion systems

March 4, 2025 | Jim Lane

This presentation by Shulin Chen of Washington State University aims to reduce the production cost of pure biomethane derived from waste through an intensified anaerobic digestion (AD) system. The IVAD system integrates a hydrothermal reactor, a hyperthermophilic anaerobic acidification reactor, and a pressurized thermophilic anaerobic methanogenesis reactor to improve digestibility and methane purity. The project […]
