Solid waste management generates big challenges for society due to its large variability in production and composition, and because of its sanitary and environmental impacts. To contribute in facing this situation, this book includes a worldwide overview of experiences and conceptual and technical developments attained through research and development projects. In addition to minimizing generation, considered as the most desirable practice, it includes alternatives of valuation for potentially recoverable waste and strategies to reduce final conditioning and disposition risks. The book includes contextual technical, economical, political and social aspects aimed at proposing integral solutions for the solid waste management.
This book, Organic Fertilizers - From Basic Concepts to Applied Outcomes, is intended to provide an overview of emerging researchable issues related to the use of organic fertilizers that highlight recent research activities in applied organic fertilizers toward a sustainable agriculture and environment. We aimed to compile information from a diversity of sources into a single volume to give some real examples extending the concepts in organic fertilizers that may stimulate new research ideas and trends in the relevant fields.
This book is dedicated to the reuse of waste and residues from the agricultural sector. Plant residues, as well as animal manure and residues from animal breeding, contain useful elements that can be processed for production of fertilizers, compost for soil recultivation, and biofuels. The emerging energy and resources crisis calls for development of sustainable reuse of waste and residues. This book contains eight chapters divided into four sections. The first section contains the introductory chapter from the editor. The second section is related to the preparation of fertilizers and compost for soil amelioration from agricultural residues and waste water. The third section considers the use of agricultural waste for solid biofuels and biogas. The fourth section discusses sustainability and risk assessment related to the use of agricultural waste and residues.
In addition to being served as a fresh vegetable, tomato is also consumed in the form of various processed products, such as paste, juice, sauce, puree and ketchup. Generally, in processing these products, different by-products including peels, seeds and pulps are produced. The rational disposal of Tomato waste represents not only a resource problem but also an environmental and economic one for the Tomato Processing Industry. Tomato Processing By-Products: Sustainable Applications indicates the alternative sustainable solutions for the recovery of tomato processing by-products as a source for animal feed and valuable components as well as their possible approaches for value-added utilization in energy, environmental and agricultural applications. Aimed at agricultural or food engineers who work in the Tomato processing industry and are seeking to improve their by-products management by actively utilizing them in effective applications. - Includes tomato processing by-products, their quantification and classification - Approaches tomato waste for animal feeding - Brings successful case study of tomato processing by-products valorization
La proliferación de huertos urbanos en las ciudades no es un fenómeno circunstancial: responde a una serie de necesidades económicas, urbanísticas, ambientales y sociales que reflejan un cambio profundo en la concepción de la ciudad y en su relación con el entorno agrícola. El presente estudio analiza la situación actual de la agricultura urbana y aporta propuestas metodológicas concretas para introducir el cultivo agrícola en la ciudad y en los edificios. Tras abordar la relación entre agricultura y sostenibilidad, el libro describe la experiencia de algunas ciudades que han introducido con éxito la agricultura en la planificación urbana (Viena, Toronto, La Habana, Rosario, Barcelona y Girona) y proporciona una serie de criterios y estrategias de actuación en los ámbitos del urbanismo y la construcción. Pensado como guía básica para conocer y desarrollar proyectos de agricultura urbana, el libro se dirige a arquitectos, paisajistas y urbanistas, así como a todas aquellas personas interesadas en los huertos urbanos.
Este libro exhibe la idea de rescatar las prácticas agroalimentarias que se utilizaban antes de la invasión de los europeos en América Latina, las cuales eran prósperas y ecológicas, y aunque no se usaba el adjetivo sustentable, éste hace muy buena referencia a ello. Se muestran las ventajas de mantener la práctica de una agricultura libre de fertilizantes y agroquímicos industriales, mostrando el beneficio de utilizar compostajes para fertilizar de forma natural el suelo y para potenciar sus nutrientes para mejorar la cosecha, así como la práctica de policultivos seleccionados para cada región, para con ello obtener el aprovechamiento que proveé el suelo sin estresarlo, como lo hace la agroindustria. Con estas prácticas se hace énfasis en no dejar perder estas costumbres en la agricultura, pues la agroecología que proponemos rescatar es el principal camino hacia una agricultura y sociedad sustentables, es el espíritu de la sustentabilidad al que aspiramos todos.
