Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Showcasing the very latest technologies for neutralising the unpleasant-and sometimes dangerous-odours from industrial and waste management processes, this Springer Brief in Environmental Sciences covers physical, chemical and biological methods. The volume includes modern biotechnological approaches now making it cost-effective to tackle malodorous chemicals at very small concentrations. The book reflects the fact that odour affects us in several ways, which range from compromising our quality of life to causing respiratory and other unpleasant conditions and from depressing property values to severe health problems caused by the toxic stimulants of odours.Innumerable industrial processes release malodourous and harmful vapours. The human sense of smell can detect some noxious chemicals, such as the sulphurous by-products of paper manufacturing, at concentrations of one part per billion. This Elektronisches Buch shows what has been achieved in combating offensive and harmful odours. While conventional air pollution control technologies can treat a wide variety of pollutants at higher concentrations, the chapters cover the more refined biological methods used to deal with odours and volatile organic compounds in low concentrations. These include bio scrubbers and bio trickling filters. Standing alongside its detailed discussion of the health impacts of total reduced sulphur compounds, and the composition of paper pulp industry emissions, this publication offers comprehensive and in-depth treatment of some of the most potent anti-odour technologies yet devised.

Taschenbuch. Condizione: Neu. Neuware -Growing concerns about the rapid depletion of fossil fuel reserves, rising crude oil prices, energy security and global climate change have led to increased worldwide interest in renewable energy sources such as biofuels. In this context, biofuel production from renewable sources is considered to be one of the most sustainable alternatives to fossil fuels and a viable means of achieving environmental and economic sustainability.Although biofuel processes hold great potential to provide a carbon-neutral route to fuel production, first-generation production systems are characterized by considerable economic and environmental limitations. The advent of second-generation biofuels is intended to produce fuels from lignocellulosic biomass, the woody part of plants that does not compete with food production. However, converting woody biomass into fermentable sugars requires costly technologies. Therefore, third-generation biofuelsfrom microalgae are considered to be a viable alternative energy resource, free from the major drawbacks associated with first and second-generation biofuels. This book examines the background of third-generation biofuel production; the advantages of algae over traditional biofuel crops; algal biomass production; algae harvesting and drying methods; production of biofuel from microalgae; and future prospects.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 92 pp. Englisch.

The microbial issues in paper mill systems, chemistry of deposits on paper machines, the strategies for deposit control and methods used for the analysis of biofouling are all dealt in this book along with various growth prevention methods. The traditional use of biocides is discussed taken into account the new environmental regulations regarding their use. Finally, discusses the trends regarding the future of the microbiological control in papermaking systems. - In-depth coverage of microbiological issues in papermaking and their consequences - Discusses eco-efficient processes (green processes) for biofilm/slime control - Offers a thorough review of the current literature with links to the primary literature - Comprehensive indexing - Author is an authority in the pulp and paper industry.

Taschenbuch. Condizione: Neu. Neuware -This book focuses on the properties of deep eutectic solvents (DESs) and recent advances in their application in lignocellulosic biomass processing. Lignocellulosic biomass conversion to biofuels, biochemicals and other value-added products has attracted global attention because it is a readily available, inexpensive and renewable resource. However, in order for biomass technologies to be commercially viable, biomass recalcitrance needs to be cost-effectively reduced. Deep eutectic solvents (DESs) are new ¿green' solvents that have the high potential for biomass processing thanks to their low cost, low toxicity, biodegradability, and easy recycling and reuse.After an overview of the current lignocellulosic biomass pretreatment, the book discusses the synthesis and physiochemical properties of DESs, as well as key findings on the effects of DES on cellulose, hemicellulose and lignin solubilization, biomass pretreatment and biomass crystallinity. It then addresses the enzymatic hydrolysis performance of DES-pretreated solids, compatibility of DESs with enzymes and microorganisms, and the recycling potential of DESs. Lastly, it compares DESs with ionic liquids, and examines the challenges and opportunities relating to extending the use of DESs in lignocellulosic processing.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 108 pp. Englisch.
