The Digest’s 2025 Multi-Slide Guide to the WorldBank and SAF

March 25, 2025 | Jim Lane

The World Bank Group (WBG) is actively involved in SAF-related engagements, focusing on country-specific feasibility assessments and strategy development. Engagements include Kenya (Mombasa Refinery), Ethiopia (SAF Roadmap), Zambia (Feasibility Studies), Colombia (Feasibility study), and Brazil (industrial decarbonization support). The WBG collaborates with organizations like GIZ, FAA, EU, ICAO, and EASA to inform continental SAF strategies […]

The Digest’s 2025 Multi-Slide Guide to Optimized Feedstock Aggregation and Blending at Scale

March 16, 2025 | Jim Lane

In this presentation, researchers chart the progress of a project focused on identifying cost-effective opportunities to deploy transformational clean energy technologies to treat organic wastes. It involves optimized conversion and biorefinery siting analysis, and characterizes the impacts of key assumptions on feedstock prices. The project uses a geospatially explicit, micro-economic optimized siting analysis, coupling experimental […]

The Digest’s 2025 Multi-Slide Guide to Waste-to-Energy Technical Assistance for Local Governments

March 13, 2025 | Jim Lane

In this presentation, researchers chart the progress of a project focused on waste-to-energy (WTE) technical assistance to local governments to support decision-making related to organic waste streams. The project mobilizes data, information, and knowledge about organic waste streams to local governments. It delivers tailored deliverables and shared resources, addressing specific waste management challenges and opportunities. […]

The Digest’s 2025 Multi-Slide Guide to Catalytic Upgrading of Waste Carbohydrates to Hydrocarbons

March 12, 2025 | Jim Lane

In this presentation, researchers chart the progress of a project focused on developing a technology for converting carbohydrates in paper sludge into hydrocarbon biofuel economically and sustainably. The project includes sludge selection, ash removal, enzymatic hydrolysis, dehydration, aldol condensation, hydro-deoxygenation, and fuel testing. The team contacted 17 paper mills and received 11 paper sludges for […]

The Digest’s 2025 Multi-Slide Guide to Renewable Natural Gas Production via Chemical Looping Gasification

March 11, 2025 | Jim Lane

In this presentation, researchers chart the progress of a project focused on a sorbent-enhanced chemical looping gasification (SE-CLG) technology for renewable natural gas production from biomass wastes. The technology integrates biomass gasification, air separation, and syngas conditioning into a single circulating fluidized bed gasifier. The project involves designing multi-functional, mixed oxide-based phase transition sorbents (PTS) […]

The Digest’s 2025 Multi-Slide Guide to Upgrading Biogas via CO2 Conversion

March 10, 2025 | Jim Lane

In this presentation, researchers chart the progress of a project focused on developing a system for in situ biogas upgrading via biological conversion of CO2 to CH4. The goal is to convert CO2 in biogas to high-quality renewable natural gas (RNG) meeting pipeline specifications. Tasks include technical verification, biological CO2 conversion with membrane-assisted H2 delivery, […]

The Digest’s 2025 Multi-Slide Guide to Mobile Bioreactor Systems for Renewable Natural Gas Production

March 9, 2025 | Jim Lane

This presentation by Kevin Harrison from the National Renewable Energy Laboratory aims to scale down a hydrogen-biomethanation system into a mobile RD&D platform to enable faster research, IP development & validation, and improved gas mass transfer to reduce the cost of RNG via biomethanation. Operational data from commissioning a 700L system showed achievement of 98% […]

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 […]
