Welcome to the Advanced Biofuels and Bioproducts Process Demonstration Unit. Part of the Lawrence Berkeley National Labs, we were established by the United States Department of Energy to help ramp up the bioeconomy.
De-Risk Your Technology With Us. They Did.
ABPDU is proud to be a partner of Cyclotron Road, a program of the Lawrence Berkeley National Laboratory supported by the U.S. Department of Energy EERE Advanced Manufacturing Office. Cyclotron Road is a home for top entrepreneurial researchers to advance energy technologies until they can succeed beyond the research lab. Cyclotron Road supports critical technology development and helps identify the most suitable business models, partners, and financing mechanisms for long-term impact. Through Cyclotron Road, companies like Visolis have collaborated with ABPDU to de-risk their technologies.

Biosynthesis of highly branched short and long-chain hydrocarbons would enable production of biofuels with desirable and tunable properties, including compression ignition fuels with low freezing points. Polyketide synthase (PKS) pathways are a promising route towards production of such compounds; engineering of PKS pathways favors a native host- this work therefore focuses on development of Streptomyces venezualae ATCC 10712 as a platform organism. While S. venezualae is well characterized for industrial production of antibiotics, currently available protocols for high density fermentation make use of rich media and high-purity dextrose. The viability of Streptomyces as a platform organism for large-scale cellulosic biofuel production is therefore currently unknown.
This study focuses on the development of protocols for high density fed-batch fermentation of S. venezualae with cellulosic sugar feed in minimal medium to evaluate the viability of this strain as a production organism for fuels and commodity chemicals.
Mixed feedstocks can help reduce the risk associated with feedstock availability for bio-based production of fuels and chemicals. This study was performed to evaluate cellulosic hydrolysates for fermentation to biofuels and also probe the possibility of reducing nutrient concentration in the broth media.
The study demonstrated that mixed feedstocks can release 80 -100% of the sugar that is obtained from corn stover alone. A hundred percent of the released sugars from mixed feedstocks can be converted to ethanol. The study also showed that alkali pretreated mixed feedstock has higher ethanol yield but lower glucose yield compared to IL pretreated mixed feedstock due to inhibition of microbial growth by residual EmimAcetate. The same ethanol yield can be achieved with lower nutrient supplied but with longer fermentation time.
This paper presents two case studies on the scale-up and process integration of municipal solid waste conversion technology. In a partnership with Idaho National Labs, we successfully demonstrated 200-fold scale up of MSW blends IL acidolysis. We also developed an integrated process for ionic liquid based deconstruction technologies for MSW blends conversion. The scale up attempt will leverage the opportunity towards a cost-effective MSW blends conversion technology.
Under a DOE Work-For-Others agreement with FATER, ABPDU has been developing and validating an integrated waste-to-energy process. Key outcomes indicate that post-consumer absorbent hygiene products (AHPs) can be readily and economically converted — without using harsh or expensive pretreatment routes — to sugars and fuel intermediates.
