Pyroliq 2019: Pyrolysis and Liquefaction of Biomass and Wastes

Biofuels from Waste to Road (WASTE2ROAD) is an EU funded project under the Grant Agreement No. 818120 within the LC-SC3-RES-21-2018 call, “Development of next generation biofuels and alternative renewable fuel technologies for road transport”, as a Research and Innovation Action of the European Union’s Horizon 2020 Programme. The project started in the fall 2018 and will run for 4 years.

In 2014, total waste production in the EU amounted to 2.5 billion tons. From this total only a limited (albeit increasing) share (36%) was recycled, while the rest was landfilled or burned, of which some 600 million tons ...

Developing A Control System To Better Understand The Effects Of Pyruvate Decarboxylase Activity On Clostridium Thermocellum Metabolism, Nicholas Cervenka

ENGS 88 Honors Thesis (AB Students)

In order for cellulosic biofuels from Clostridium thermocellum to be commercially viable, the ethanol yield and titer of the microbe must be increased. To accomplish this, it has been suggested to introduce the Pyruvate Decarboxylase (PDC) enzyme into C. thermocellum. In order to demonstrate effects on ethanol production by PDC prior to genetic modification, a cell free system (CFS) has been developed. A purified enzyme system was developed with the CFS to function as a control. Using the purified enzyme system, PDC from Saccharomyces cerevisiae was demonstrated to be a good candidate for further testing in the CFS.

Biofuel Supply Chain Restructuring -- An Economic Viability And Environmental Sustainability Investigation For Enhancing Second Generation Biofuel Adoption, Rajkamal Kesharwani

Doctoral Dissertations

"Biofuel is a promising clean alternative to fossil fuels. Currently, first generation biofuels are commercially produced by using corn grain as biomass feedstock. However, the use of edible matter of crops, may lead to a competition between food and fuel. Therefore, there is a significant push in both industry and academia to commercialize second generation biofuel manufacturing technology, which uses non-edible matter from crops. Most research focuses on individual manufacturing processes for producing second generation biofuel, but the economic and environmental impacts of a large-scale adoption of second generation biofuel manufacturing have been less widely reported.

Low Moisture Anhydrous Ammonia (Lmaa) Pretreatment Of Lignocellulosic Biomass And Assessments For Biobutanol Production, Nazira Binti Mahmud

Graduate Theses and Dissertations

Low-value biomass materials such as processing co-products and agricultural wastes possess abundant potential in value-added products production. The effort for utilization of these materials, especially as the substrate for fermentation process was limited by the low availability of fermentable sugar. This is due to the presence of lignin and hemicellulose in biomass structure, which entails appropriate pretreatment procedure to be conducted to expose the cellulose for the enzymatic reaction. Alkali-based pretreatments offer the attractive benefit of low inhibitor compound production. In this study, low moisture anhydrous ammonia (LMAA) pretreatment was conducted on selected biomass. Anhydrous ammonia, which is a gaseous ...
