Opis

This book is a collection of chapters concerning the use of biomass for the sustainable production of energy and chemicals-an important goal that will help decrease the production of greenhouse gases to help mitigate global warming, provide energy security in the face of dwindling petroleum reserves, improve balance of payment problems and spur local economic development. Clearly there are ways to save energy that need to be encouraged more. These include more use of energy sources such as, among others, manure in anaerobic digesters, waste wood in forests as fuel or feedstock for cellulosic ethanol, and conservation reserve program (CRP) land crops that are presently unused in the US. The use of biofuels is not new; Rudolf Diesel used peanut oil as fuel in the ?rst engines he developed (Chap. 8), and ethanol was used in the early 1900s in the US as automobile fuel Songstad et al. (2009) Historical perspective of biofuels: learning from the past to rediscover the future. In Vitro Cell Dev Biol Plant 45:189-192). Brazil now produces enough sugar cane ethanol to make up about 50% of its transportation fuel needs (Chap. 4). The next big thing will be cellulosic ethanol. At present, there is also the use of Miscanthus x giganteous as fuel for power plants in the UK (Chap. 2), bagasse (sugar cane waste) to power sugar cane mills (Chap. 4), and waste wood and sawdust to power sawmills (Chap. 7).

Recenzje

From the reviews:

"Conversion of biomass to ethanol, diesel substitutes, and other biofuels is the only option for significantly reducing dependence on petroleum for the liquid fuels that are essential to air travel, heavy-duty trucking, and long-distance travel. Here, the editors have compiled expert contributions and perspectives on a wide range of topics. ... The contributors are invariably realistic and sober about the challenges and achievements possible. ... Summing Up: Recommended. Students of all levels, researchers/faculty, and professionals/practitioners." (W. Loescher, Choice, Vol. 48 (8), April, 2011)

The successful use of plant biomass for the sustainable production of energy and co-products such as chemicals is critically important for the future of humanity. Large scale exploitation of biomass is needed to decrease the production of greenhouse gases and help mitigate global warming, to provide energy security in the face of declining petroleum reserves, to improve balance of payment imbalances, and to spur local economic development. This volume discusses such uses of plant biomass as well as ways to improve the productivity and composition of plant species, including trees, perennial and annual grasses, oil-producing plants and algae, that have the potential to produce substrates such as sugar, starch, oil and cell walls, as well as energy and co-product substrates. The problems of invasiveness and gene dispersal are discussed, as are ways to mitigate these. Among the topics covered are models for integrated biorefineries to produce many co-product chemicals, the use of corn stover to power ethanol plants, life cycle analysis of biofuels, and criteria for biomass sustainability and certification. This is indeed an exciting and fast-moving time for advocates of plant biomass-based technology.
