Enzymatic digestion of microalgal biomass for lipid, sugar and protein recovery
Project ID: D2013-77 Background The rising concern around the sustainability of petrochemicals are prompting searches for more environmentally friendly and inexpensive feedstocks. Bio-based alternatives are attractive, but also require microbial fermentation. Enzyme hydrolysis is a promising way to reduce the cost of the pretreatment process. Invention...

Selective recovery of polypropylene (and polyethylene) from mixed plastic wastes
Project ID: D2021-43 Background Polypropylene (PP) is a thermoplastic polymer used in packaging materials, consumer goods, automotive components, and medical devices. It is difficult to recover PP from mixed plastic waste streams; PP has a similar density to polyethylene (PE) and cannot be selectively separated from PE via the sink-float methods...

High yield production of fuels and petro- or oleo-chemical precursors from vegetables oils/liquid feedstocks in a continuous-flow pyrolysis reactor
Project ID: D2016-39Background Pyrolysis of oil seeds and microalgae has the potential to displace petroleum-derived fuels. Current methods require batch processing which produces low yield of liquid products, contamination from secondary reactions, and causes buildup inside the reactor. Therefore, there is a need to improve the efficiency of pyrolysis...

Two-step method for production of multiple biofuels and products from Non-Lignocellosic Biomass
Project ID: D2015-31Background Biomass of non-lignocellulosic origin is typically composed of one or more of three components – protein, starch and oils (such as triacylglycerides or other lipids). One of the concerns with thermochemical processing of protein-containing biomass is contamination of bio-oil with nitrogen-containing compounds (such...

High Yield Algal Biomass Production Without Concentrated CO¬2 Supply Under Open Pond Conditions
Project ID: D2016-72 IP Status: US Patent 11015167-B2 Background Biorefineries are working to create sustainable solutions via conversion of biomass. Microalgae has been a popular choice for biomass inputs due to fast growth rates and their ability to grow on waste waters and marginal lands. Cultivation of microalgae in an open pond system...

Cost- and Energy-Efficient Device for De-watering Microalgae Using Stimuli-Sensitive Hydrogels
Project ID: D2016-01 IP Status: US Patent 10,077,422 Invention Description: Currently, a major hurdle for commercial-scale production of fuels and other products from microalgae is recovering algal biomass from growth media with minimal cost and energy input. When cultivated in open raceway ponds, microalgae concentrations are very low – typically...
