SPME Device for Determining the Partition Coefficient of Xenobiotics into Marine Biomass

Project ID: TECH2023-34 Background Several studies have been conducted over the last few decades on the physical properties and chemical composition of the sea-surface microlayer as well as its chemical exchange processes at the air/sea interface. As a result of these studies, it has been demonstrated that a wide variety of xenobiotics are accumulated...

Toward Wet Wipes that Turn into Toilet Paper when Flushed

Project ID: TECH-2023-20 Background Wet wipes have been shown to clog pipes and pumps in wastewater collection and treatment systems. Additionally, wet wipes contain microplastics that contribute to water pollution. Some governments are proposing restrictions or complete bans on wet wipe products. Therefore, there is a need for a truly flushable...

Tie Layers for Recyclable Barrier Films

Project ID: D2022-11 Background Multilayer packaging consists of thin layers of materials adhered on top of one another. The composition of layers is chosen based on performance needs, such as protection from moisture, oxygen, light, odor, flavor, or abrasion. Although these varying material properties contribute to performance advantages, they also...

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...
