Approximately more than 400 billion liters of bioethanol could be produced each year from crop by-products.Breaking down agricultural waste has been difficult because ...Wed, 15 Apr 2015 17:00:00 +0800Research and DevelopmentMicrobial Propane Synthesis Based on Butanol Pathway is a hydrocarbon used in a wide range of applications and is a target in research for developing new renewable fuels. Patrik R. Jones and Nigel S. Scrutton from University of Turku in Finland and University of Manchester in UK, respectively, constructed and evaluated alternative microbial pathways for propane production. The new pathways we...Wed, 15 Apr 2015 17:00:00 +0800Research and DevelopmentEngineered Microbe Can Produce Ethanol from Plant Biomass Without Pretreatment Washington, scientists have refined a strategy known as consolidated bioprocessing (CPB) to reduce costs of producing ethanol from plant biomass. Now, scientists try to engineer a strain of a CBP bacterium called Caldicellulosiruptor bescii that can break down biomass without pretreatment and produce ethanol as well.Caldicellulosiruptor bescii h...Wed, 15 Apr 2015 17:00:00 +0800Research and DevelopmentAlgae from Clogged Waterways could serve as Biofuel Feedstock algal blooms from farm fertilizer runoff can destroy aquatic life and clog rivers. However, scientists are now working on a way to clean up these algal blooms and turn them into feedstock for biofuels through a nutrient bio-remediation system.Currently, the research team is exploring different substrates to optimize algae growth in wate...Wed, 15 Apr 2015 17:00:00 +0800Research and DevelopmentPortland Wastewater Treatment Plant to Produce Renewable Vehicle Fuel Portland City Council has approved the development of a facility at the Columbia Boulevard Wastewater Treatment Plant that will convert biogas into compressed natural gas vehicle fuel. The facility, which is expected to be operational by 2017, would allow the plant to re-use nearly all of the 600 million cubic feet of biogas it produces annuall...Wed, 15 Apr 2015 17:00:00 +0800News and TrendsScania and Swedfund Collaborate to Invest in Biogas Production in India together with Swedfund, the development financier of the Swedish state, are forming a partnership to develop the production of biogas as an vehicle fuel in Nagpur in India. The biogas will be produced from digested sludge from one of the city's wastewater treatment plants."This is a Swedish venture, which in a sustainable and profitable mann...Wed, 15 Apr 2015 17:00:00 +0800News and TrendsGM Tobacco Plants May Boost Biofuel Industry try to genetically modify tobacco to produce enzymes for breaking down biomass from forest raw materials. This may lead to a more effective, economic, and sustainable production of biofuels.A Norwegian-based research project now aims to develop low cost production of industrial enzymes using tobacco plants as a "green factory". Such enz...Wed, 15 Apr 2015 17:00:00 +0800Biofuels ProcessingDOE Develops Catalyst for Ethane-to-Ethanol Production Process California, researchers at the DOE's Molecular Foundry nanoscience research center designed a new material that could pave the way for the adoption of cheaper, cleaner-burning fuels.Ethanol, the liquid form of the natural gas ethane, is an attractive form of liquid fuel because it burns cleaner and provides greater energy. Unfortunately, making ...Wed, 15 Apr 2015 17:00:00 +0800Biofuels Processing
