This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: En el presente documento, se estudia la viabilidad de la implantación de una empresa con actividad enfocada a la gestión y producción de biomasa. La finalidad del proyecto, es valorar si la actividad desarrollada por la empresa y bajo un supuesto nivel de ventas puede generar beneficio y rentabilizar la inversión en menor tiempo posible. En base a unas necesidades medioambientales de las áreas forestales y la oportunidad de generar nuevas fuentes de negocio, se propone desarrollar la implantación de una industria enfocada a la gestión forestal y aprovechamiento y transformación de biomasa residual. Se dimensiona la nave para disponer de una capacidad de producción nominal de 10.000 toneladas anuales, y se definen un conjunto de espacios necesarios para poder almacenar toda la biomasa. También se realiza una simulación de qué volumen de calderas se puede suministrar biomasa para la cantidad de producción establecida, y realizar una previsión de la demanda a un escenario futuro cercano. Poder procesar tal volumen de biomasa residual, genera una gran dependencia de recursos naturales forestales que se generan en el entorno. Para ello, se decide dar servicio de gestión forestal sostenible para poder mantener en buen estado las masas forestales y establecer un servicio para obtener la materia prima de la cadena de producción. Para poder obtener una astilla de calidad, se diseña la planta para poder tener capacidad de realizar el proceso de transformación de biomasa residual forestal en astillas. Se evalúan los recursos necesarios para llevar a cabo la actividad, y desarrollar diferentes actividades con el mínimo de recursos. Para demostrar la rentabilidad de la actividad de la empresa, se realiza un estudio económico-financiero para valorar si para dicha producción de biomasa puede generar beneficios con la actividad y evaluar la rentabilidad del proyecto a un futuro próximo. En los primeros capítulos del documento anexos, se pretende dar a conocer qué es la biomasa, qué ventajas proporciona, cómo podemos aprovechar los recursos de la biomasa para sustituir otras fuentes de energía y cuál es el papel que desarrolla la biomasa en los últimos años en la sociedad.
Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.

Download or read book Biological Wastewater Treatment written by Mogens Henze and published by IWA Publishing (International Water Assoc). This book was released on 1881 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: For information on the online course in Biological Wastewater Treatment from UNESCO-IHE, visit: http://www.iwapublishing.co.uk/books/biological-wastewater-treatment-online-course-principles-modeling-and-design Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. Biological Wastewater Treatment addresses this deficiency. It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. The book forms part of an internet-based curriculum in biological wastewater treatment which also includes: Summarized lecture handouts of the topics covered in book Filmed lectures by the author professors Tutorial exercises for students self-learning Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence.

Available in PDF, EPUB and Kindle. Book excerpt: Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Download or read book Public Policies and the Misuse of Forest Resources written by World Resources Institute and published by Cambridge University Press. This book was released on 1988-09-30 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Six contributors explore the role of governments in accelerating the rate of forest destruction by providing direct and indirect subsidies to support what would otherwise be non-commercial logging operations. Without these financial incentives, most timber operations in the tropics would cease. In a series of country-by-country investigations, including examples from the developed and developing worlds, this book documents the government policies that are leading to the misuse of forest resources. Each is written by an authority on the county, and each contains descriptive, analytical and empirical material on key policies and their effects. The final country analysis focuses on the United States, where the consequences of the subsidized timber sales by the US Forest Service from most of the national forests are discussed. The book concludes with an overview of the impact of forest policies and the role of bilateral and multilateral agencies in their formulation. By directing attention toward the political dimension involved in forest clearance, this book will provide a clearer insight into the basic reasons why forests continue to be destroyed despite the outcry raised by conservationists.
