A new process uses a novel catalyst to synthesize isoprene in high yields. Isoprene is made by contacting 3-methyltetrahydrofuran (MTHF) with a heterogeneous acid catalyst (other than alumina, or Al2O3). This catalytic process dehydrates MTHF to isoprene via several combinations of temperatures, pressures, and space velocities (reactant volumetric flow rate per volume of catalyst) and achieves conversion rates of MTHF to isoprene of up to 100%.View Technology
A process has been developed for synthesizing two new dimethacrylate monomers from glucose and mannose. The materials produced by the sugar-derived dilactones undergo degradation in basic conditions while remaining stable in neutral and acidic environments. The dimethacrylates are derived from sugars, making them renewable and comparable to petroleum-based sources. The monomers reported are sugar-derived dimethacrylates, and provide a pathway to create sustainable materials for use in coatings, thermosets, adhesives and particle-based drug delivery.View Technology
An isosorbide-based methacrylate monomer has been synthesized and polymerized to produce block polymers. This new isosorbide derivative, acetylated methacrylic isosorbide (AMI), is easily synthesized from commercially available starting materials in just two steps. The AMI monomer can further be polymerized to form block copolymers.View Technology
A method of creating a scalable block copolymer from a new branched lactone monomer has been developed. The new lactone monomer is generated from direct fermentation of sugar. The biobased monomer, when copolymerized with lactide, has many utilities and its mechanical properties (e.g. stretchiness, strength) can be tuned depending on the application requirements. Sugar (glucose) is one of nature’s simplest and most common organic compounds, and the resultant polymers from this new process are biodegradable, affordable, and available for mass-production. Applications of these polymers are disposable materials, thermoplastics, and sustainable plastic components.View Technology
A catalytic process allows commodity olefins to be synthesized from the carboxylic acids of biomass. This bio-based feedstock approach is a desirable method for generating olefins that can be used to make plastics and other chemicals. The process, which involves the decarbonylation of carboxylic acids from biomass, creates olefins such as styrene, acrylates, acrylonitrile and octene in moderate to good yield. Furthermore, by adding a tandem Heck-type coupling reaction, the process can also generate stilbenes, which are desired bioactive targets.View Technology
Biological pathways that produce isobutyric acid from sugar-based feedstocks have been developed using fungal and bacterial enzymes. These biological pathways are more environmentally friendly and direct than chemical synthesis. Note: This technology for producing isobutyric acid has been exclusively licensed to Ascenix Biotechnologies.

To reduce the costs of making valuable C4-C5 renewable chemicals, a biosynthetic pathway has been developed to generate C4-C5 chemicals, such as succinate, amino acids and 1,4-butanediol. This new pathway from sugars involves only five fermentation steps, as compared to the current pathway, which requires 23 steps. The new process uses engineered microbes and a simple pathway that produces less contaminating byproducts and higher yields (50% higher theoretical yield). This new approach makes the production of cost-effective renewable bioplastics, polyesters and spandex a possibility.

A process developed at the University of Minnesota can strengthen polylactic acid using less added material (as little as 1 wt% of non-polyactic acid material as opposed to 2-3 wt% for commercial additives) by creating a co-polymer. This added strength expands the potential polylatic acid applications to replacement of high impact polystyrene and packaging.

“Valerian Materials will lead the way in renewable, degradable, and recyclable polymers. The biomass derived materials have applications as resilient foams and elastomers as well as tough plastics and thermosets. The principal technology relies on efficient and economical fermentation of sugar to give small molecules that can be catalytically converted to polymers in high yields at low temperatures with controlled molar mass. The versatility of the polymer platform is a key aspect and allows for broad penetration in a wide variety of industries. ” — Valerian MaterialsValerian Materials Website
