Prospective technologies, feedstocks and market innovations for ethanol and biodiesel production in the US

چکیده

In recent years, production and consumption of biofuels has become controversial, mainly due to the competitive use of natural resources for food/feed and fuel production. Second generation biofuels (with cellulosic ethanol being on top of developments nowadays) have a great potential to provide an economically feasible solution. However, high processing costs related to breaking down cellulosic plant material and converting it to sugar (and fuel), missing infrastructure and environmental impacts can be detrimental. This paper discusses various biofuels technologies and feedstocks that have a potential to emerge as prospective feedstocks for second generation biofuels production in the future on the US market. It also emphasizes existing challenges that could hinder the development of these technologies and their commercialization in the long-term.

Production and Use of Lipases in Bioenergy: A Review from the Feedstocks to Biodiesel Production

Lipases represent one of the most reported groups of enzymes for the production of biofuels. They are used for the processing of glycerides and fatty acids for biodiesel (fatty acid alkyl esters) production. This paper presents the main topics of the enzyme-based production of biodiesel, from the feedstocks to the production of enzymes and their application in esterification and transesterifica...

INVITED REVIEW Biodiesel production, properties, and feedstocks

Biodiesel, defined as the mono-alkyl esters of vegetable oils or animal fats, is an environmentally attractive alternative to conventional petroleum diesel fuel (petrodiesel). Produced by transesterification with a monohydric alcohol, usually methanol, biodiesel has many important technical advantages over petrodiesel, such as inherent lubricity, low toxicity, derivation from a renewable and do...

Biofuels and Their Co-Products as Livestock Feed: Global Economic and Environmental Implications.

This review studies biofuel expansion in terms of competition between conventional and advanced biofuels based on bioenergy potential. Production of advanced biofuels is generally more expensive than current biofuels because products are not yet cost competitive. What is overlooked in the discussion about biofuel is the contribution the industry makes to the global animal feed supply and land u...
