Team uses a cellulosic biofuels byproduct to increase ethanol yield

CHAMPAIGN, Ill. — Scientists report in Nature Communications that they have engineered yeast to consume acetic acid, a previously unwanted byproduct of the process of converting plant leaves, stems and other tissues into biofuels. The innovation increases ethanol yield from lignocellulosic sources by about 10 percent. Lignocellulose is the fibrous material that makes up the structural tissues of plants. It...

University of Tennessee professor and student develop device to detect biodiesel contamination

The probability of contamination of diesel fuel is increasing as biodiesel becomes more popular and as distribution and supply systems use the same facilities to store and transport the 2 types of fuels In 2010, a Cathay Pacific Airways plane was arriving in Hong Kong when the engine control thrusts seized up and it was forced to make a hard landing—injuring dozens. The potential culprit? Contaminated fuel. The...

New possibilities for efficient biofuel production

Limited availability of fossil fuels stimulates the search for different energy resources. The use of biofuels is one of the alternatives. Sugars derived from the grain of agricultural crops can be used to produce biofuel but these crops occupy fertile soils needed for food and feed production. Fast growing plants such as poplar, eucalyptus, or various grass residues such as corn stover and sugarcane bagasse...

SA’s first sugar beet harvest could come in earlier than anticipated

South Africa’s first commercial plantings of sugar beet are yielding promising results, and the first crops may even be ready for harvest three months earlier than previously anticipated. Go to Source Tags: sugar beet, plantings, harvest ...

Construction of E Cape bioethanol plant to start next year

Construction of a large-scale 90-million-litres bioethanol production facility is expected to start in the second quarter of next year, a Central Energy Fund (CEF) official said on Friday. CEF biofuels project manager Sibusiso Ngubane stated that this project was a joint venture between State-owned financier, the Industrial Development Corporation (IDC), CEF, and Sugar Beet South Africa.

Forecasting a change in technology: are Dye-sensitised Solar Cells a source of ubiquitous energy?

The purpose of this paper is to review developments in Dye-sensitised Solar Cells (DSC) and discuss the feasibility of the technology as a future source of ubiquitous energy. Rapid technological developments have made the technology a viable future photovoltaic technology, but its overall impact is still unclear. This review on recent developments strives, based on historical developments, to forecast the future...

Management of the Photovoltaic Supply Chain

The Photovoltaic (PV) Supply Chain (SC) has been infrequently examined in SC literature. The PVSC is unique in that it is heavily driven by government policy and dependent on subsidies, sensitive to inventory fluctuations, raw material shortages, and geo-political tensions, and does not fit into traditional SC models.
