Book Description
Este libro es un manual completo para el reciclaje de residuos domésticos y de jardín. Ilustra todas las técnicas para obtener un excelente fertilizante y acondicionador de suelo de forma gratuita. Una familia de 3-4 personas con un huerto de tamaño normal puede producir 5 quintales de residuos orgánicos al año de los que fácilmente se pueden obtener 2 quintales de compost, equivalentes a diez bolsas de 50 litros de tierra de jardín. Esto reduce los costes de compra de fertilizantes prácticamente a cero. Además, muchas administraciones locales ofrecen descuentos y concesiones a quienes producen su propio compost. El libro ilustra todas las técnicas para obtener gratis un excelente fertilizante y acondicionador del suelo. El texto se enriquece con fichas, tablas e imágenes que guían al lector en la producción de compost tanto en el jardín como en el balcón de la casa, incluso con una compostera de construcción propia.. Durante millones de años, en la Tierra, una enorme masa de sustancia orgánica ha estado "muriendo". En nuestros jardines, como en los parques y bosques del planeta, todas las especies de plantas e insectos, así como los animales superiores, renuevan su presencia según los ciclos de la naturaleza. Si consideramos el número de hojas de un árbol o la cantidad de hierba que hay en la extensión de un césped, podemos imaginar la masa de materia orgánica que acaba en el suelo donde se descompone más o menos rápido. Sin embargo, este enorme nivel de materia en descomposición no causa contaminación. Basta con adentrarse en un bosque en invierno y remover el manto de hojas muertas bajo los árboles: no surgirá olor a putrefacción, si acaso, un olor incluso agradable para los amantes de la naturaleza. Excavando debajo de las hojas, después de unos centímetros se encuentra con un suelo de color oscuro, rico en humus. Es la conocida tierra forestal, muy buscada para muchos cultivos. La tierra forestal es un producto precioso del trabajo de la naturaleza. Si, por el contrario, pensamos en nuestros residuos de cocina, que tiramos a la papelera, enseguida notamos la diferencia: de hecho, al cabo de un tiempo se pudren y desprenden un olor repugnante. La diferencia entre el trabajo que realiza la naturaleza en el bosque y el trabajo que realizamos nosotros en el basurero radica en que el bosque es un organismo vivo. Los desechos que caen al suelo encuentran miles de millones de hongos, bacterias, nematodos, gusanos, insectos. Este es un pequeño ejército dispuesto a luchar para convertir los desechos en humus. Todos estos agentes de la naturaleza, con el aporte de oxígeno, provocan una transformación positiva. El compostaje casero, el tema de este libro, ilustra las técnicas necesarias para asegurar que incluso los desechos de nuestra cocina y nuestro jardín se eliminen del proceso de putrefacción y se transformen en humus.

Book Description
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Book Description
The IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes was created with the aim to produce a generic model and common platform for dynamic simulations of a variety of anaerobic processes. This book presents the outcome of this undertaking and is the result of four years collaborative work by a number of international experts from various fields of anaerobic process technology. The purpose of this approach is to provide a unified basis for anaerobic digestion modelling. It is hoped this will promote increased application of modelling and simulation as a tool for research, design, operation and optimisation of anaerobic processes worldwide. This model was developed on the basis of the extensive but often disparate work in modelling and simulation of anaerobic digestion systems over the last twenty years. In developing ADM1, the Task Group have tried to establish common nomenclature, units and model structure, consistent with existing anaerobic modelling literature and the popular activated sludge models (See Activated Sludge Models ASM1, ASM2, ASM2d and ASM3, IWA Publishing, 2000, ISBN: 1900222248). As such, it is intended to promote widespread application of simulation from domestic (wastewater and sludge) treatment systems to specialised industrial applications. Outputs from the model include common process variables such gas flow and composition, pH, separate organic acids, and ammonium. The structure has been devised to encourage specific extensions or modifications where required, but still maintain a common platform. During development the model has been successfully tested on a range of systems from full-scale waste sludge digestion to laboratory-scale thermophilic high-rate UASB reactors. The model structure is presented in a readily applicable matrix format for implementation in many available differential equation solvers. It is expected that the model will be available as part of commercial wastewater simulation packages. ADM1 will be a valuable information source for practising engineers working in water treatment (both domestic and industrial) as well as academic researchers and students in Environmental Engineering and Science, Civil and Sanitary Engineering, Biotechnology, and Chemical and Process Engineering departments.

Book Description
This book guides architects, landscape designers, urban planners, agronomists and society on the implementation of sustainable rooftop farming projects. The interdisciplinary team of authors involved stresses the different approaches and the multi-faceted forms that rooftop farming may assume in any context. While rooftop farming experiences are sprouting all over the world the need for scientific evidence on the most suitable growing solutions, policies and potential benefits emerges. This volume brings together existing experiences as well as suggestions for planning future sustainable cities.

Book Description
In 1982 the International Association on Water Pollution Research and Control (IAWPRC), as it was then called, established a Task Group on Mathematical Modelling for Design and Operation of Activated Sludge Processes. The aim of the Task Group was to create a common platform that could be used for the future development of models for COD and N removal with a minimum of complexity. As the collaborative result of the work of several modelling groups, the Activated Sludge Model No. 1 (ASM1) was published in 1987, exactly 25 years ago. The ASM1 can be considered as the reference model, since this model triggered the general acceptance of wastewater treatment modelling, first in the research community and later on also in practice. ASM1 has become a reference for many scientific and practical projects, and has been implemented (in some cases with modifications) in most of the commercial software available for modelling and simulation of plants for N removal. The models have grown more complex over the years, from ASM1, including N removal processes, to ASM2 (and its variations) including P removal processes, and ASM3 that corrects the deficiencies of ASM1 and is based on a metabolic approach to modelling. So far, ASM1 is the most widely applied. Applications of Activated Sludge Models has been prepared in celebration of 25 years of ASM1 and in tribute to the activated sludge modelling pioneer, the late Professor G.v.R. Marrais. It consists of a dozen of practical applications for ASM models to model development, plant optimization, extension, upgrade, retrofit and troubleshooting, carried out by the members of the Delft modelling group over the last two decades.

Book Description
The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.

Book Description
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.
