Biogas Conversion to RNG

Given the ideal circumstances, landfills offer good biogas conversion to RNG possibilities. Landfills produce a very large volume of biogas that can be converted to Renewable Natural Gas.  Landfills are typically very large, and when they have been designed to efficiently retrieve the generated biogas from the landfill, it is usually a very large volume,…

Emerging Feedstocks – Genetically Modified Trees

Genetically modified trees have been extensively academically explored as ideal feedstocks for pulp/paper and cellulosic ethanol. Novel trees include modifications that increase cellulose content, reduce lignin content, and even change lignin monolignol ratios. However, companies considering investing in these engineered managed forests need to examine technoeconomic feasibility prior to adoption. Specific attention to regulations, site…

Ethanol Proteins – Advanced Process Monitoring

Ethanol plants achieve the best quality ethanol proteins through advanced process monitoring and control.   That means starting with consistent control of corn grinding, cook and liquefaction and fermentation so that each fermentation batch is very consistent in terms of starch converted to ethanol.  Most ethanol plants were designed with simple DCS process control and simple…

Ethanol Protein – Importance of Co-Product Quality

Why is the importance of ethanol protein co-product quality? At least eight ethanol plants have recently installed new process technology that separates higher value corn fermentation protein from whole stillage. This ethanol protein is a combination of corn protein and yeast protein from the ethanol fermentation process. This protein product is destined for growing animal…

Site Planning to Mitigate Environmental Risks

In well-developed bioeconomy projects, initial site planning, placement of facilities, and mitigation of potential environmental risks, are the factors that help improves a project’s chance of overall economic success.  It is critical for project developers and land managers to work together in developing optimization models that guide systematic, multi-objective planning efforts, collectively including biodiversity and…

Biomass Wildlife Impact

It is well known that sustainable feedstock development is the cornerstone of the bioeconomy, but does sustainable biomass production  encompasses things like wildlife impact, and more than just reliable annual yields of high-quality feedstock?  Biomass provides habitat for our nation’s wildlife resources, a source for capturing carbon in our soils, material that can intercept and…

PFAS Experts

PFAS is short for “poly and perfluoroalkyl substances”.  You likely encounter it regularly, maybe multiple times a day. You might even consume it.  PFAS, a class of more than 4,000 different chemicals, is everywhere. It turns up in everything from household items to fast food wrappers. It has even been found in our blood. And new…

Biochemical Conversion Processes

Biochemical conversion processes? Enzymes and micro-organisms are frequently used as biocatalysts to convert biomass or biomass-derived compounds into desirable products. Biotechnology advances are expected to lead to dramatic biochemical conversion improvements. The most popular biochemical technologies are anaerobic digestion (or biomethanation) and fermentation. Cellulase and hemicellulase enzymes break down the carbohydrate fractions of biomass into…
