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…

Feedstocks: Agricultural

Agricultural Feedstocks for the renewable energy industry include starch and sugar crops (e.g., corn, sorghum), grass crops (e.g., switch grass, miscanthus), oil crops (e.g., soybean, sunflowers), and crop residues (e.g., corn stover, corn cobs, nut shells).  Agricultural feedstocks can create sustainable paths by using marginal croplands to generate energy products, and by adding value or…

Energy Crop Expert

What is an energy crop expert? An energy crop expert is someone that understands the many complexities of those plants that are grown solely for producing energy as opposed to those grown for food or fiber. These crops come in many forms and varieties; energy cane, miscanthus, biomass sorghum and switchgrass are some of the…

Biomass Sourcing, Storage, and Preparation

Many biomass-based projects show that problems frequently occur due to over-simplified assumptions as to the sources, delivering quality and quantity, storage and reclaim requirements, and pre-processing of biomass to meet the process feedstock specifications.  If your region needs an alternative to landfilling and seeks not only recycling of the easy stuff – clean paper, plastics, and…
