Indian researchers propose fuel-chemicals-electricity cellulosic biomass biorefinery scheme
April 19, 2015
Researchers from the CSIR-Indian Institute of Petroleum are proposing a biorefinery scheme using lignocellulosic biomass feedstock (sugarcane bagasse) for the production of fuel (ethanol), chemicals (furfural), and energy (electricity). The proposed scheme could be integrated with existing sugar or paper mills, where the availability of biomass feedstock is in abundance as a means to address some of the cost and logistics issues, they suggest in their paper published in the ACS journal Energy & Fuels.
In their approach, they extract fermentable sugar components (xylose and glucose) from sugarcane bagasse employing acid hydrolysis and enzymatic saccharification; recovery and reuse of the enzyme is a process advantage. The pentose fraction is used for yeast biomass generation and furfural production. High-temperature fermentation of the hexose stream by the thermophilic yeast Kluyveromyces sp. IIPE453 with cell recycle produces ethanol with an overall yield of 88% ± 0.05% and a productivity of 0.76 ± 0.02 g/L h−1. A complete material balance on two consecutive process cycles, each starting with 1 kg of feedstock, resulted in an overall yield of 366 mL of ethanol, 149 g of furfural, and 0.30 kW of electricity.
Algenol and Reliance launch algae fuels demonstration project in India
January 21, 2015
Algenol and Reliance Industries Ltd., have successfully deployed India’s first Algenol algae production platform. The demonstration module is located near the Reliance Jamnagar Refinery, the world’s largest. The demonstration has completed several production cycles of Algenol’s wildtype host algae, but ultimately could demonstrate the fuels production capabilities of Algenol’s advanced fuel producing algae and systems. Th
The Algenol fuel production process is designed to convert 1 tonne of CO2 into 144 gallons of fuel while recycling CO2 from industrial processes and converting 85% of the CO2 used into ethanol, gasoline, diesel and jet fuels. The advanced fuel producing algae technology is successfully operating at Algenol’s Fort Myers, Florida headquarters.
Expanded UMTRI study finds self-driving vehicles generate enthusiasm, concerns worldwide; interest highest in China and India
November 02, 2014
Despite safety concerns about equipment failure, a majority of drivers on three continents have high expectations for autonomous vehicles. Building on an earlier study on public opinion regarding self-driving vehicles in the US, Great Britain and Australia (earlier post), Brandon Schoettle and Michael Sivak of the University of Michigan Transportation Research Institute (UMTRI) expanded their survey to include more than 1,700 respondents in India (527), China (610) and Japan (585). The report includes recently released findings from the same survey in the US, the UK, and Australia.
They found that about 87% of respondents in China and 84% in India have positive views regarding autonomous and self-driving vehicles, compared to 62% in Australia, 56% in the US, 52% in the UK and 43% in Japan. Half of the Japanese respondents were neutral, while the US registered the highest percentage of negative views (16%) among the six countries.
Study: surface ozone in India in 2005 damaged 6M tonnes of crops, enough to feed 94M people in poverty
September 04, 2014
Surface ozone pollution in India damaged 6 million metric tons (6.7 million US tons) of India’s wheat, rice, soybean and cotton crops in 2005, according to a new study published in Geophysical Research Letters, a journal of the American Geophysical Union.
India could feed 94 million people with the lost wheat and rice crops, or about a third of the country’s poor, according to Sachin Ghude, an atmospheric scientist at the Indian Institute of Tropical Meteorology (IITM) in Pune, India and lead author of the new study. There are about 270 million Indians that live in poverty, according to the study.
