The Environmental Management of Low-Grade Fuels


Book Description

The negative environmental impacts of energy use, particularly soil and water pollution, continue to present serious policy dilemmas. The release of emissions and effluents and the build-up of solid waste throughout the fuel cycle have disruptive effects on natural habitats and human health. Further, fuel combustion can result in the emission of carbon dioxide, ozone, methane and nitrogen dioxide the 'greenhouse gases' which have been linked to climate change. The safe and sustainable use of energy has become an important issue in the wider environmental debate. In this report, researchers from the Stockholm Environment Institute explore the issues raised by the use of low-grade fuels such as peat, wood, biomass, lignite, oil shale and municipal and industrial wastes. The present strategies and policy options for all stages of the process, from mining and transport to processing and combustion. With those who would like to learn more about these fuels in mind, the material is presented clearly, and discussions of environmental protection measures are given in table form throughout the ease of reference. A directory of environmental guidelines, regulations and standards is given in an appendix. While a high calorific value fuels remain the most significant source of energy in many countries, economic and other constraints on the use of these fuels may result in more nations turning to low-grade sources of energy to operate their industrial or transportation sectors. The greater potential for environmental degradation that accompanies the use of low-grade fuels means that it is crucial that environmentally sound methods for their management, such as those presented here, be more widely available. The Environmental Management of Low-Grade Fuels will be valuable for industry specialists, policy makers, students and all who are concerned with the life cycle of these materials. Mary MacDonald is an affiliated scientist, and Michael Chadwick is a former director, at the Stockholm Environment Institute.

Sustainable Food Waste-to-Energy Systems


Book Description

Sustainable Food Waste-to-Energy Systems assesses the utilization of food waste in sustainable energy conversion systems. It explores all sources of waste generated in the food supply chain (downstream from agriculture), with coverage of industrial, commercial, institutional and residential sources. It provides a detailed analysis of the conventional pathways for food waste disposal and utilization, including composting, incineration, landfilling and wastewater treatment. Next, users will find valuable sections on the chemical, biochemical and thermochemical waste-to-energy conversion processes applicable for food waste and an assessment of commercially available sustainable food waste-to-energy conversion technologies. Sustainability aspects, including consideration of environmental, economic and social impacts are also explored. The book concludes with an analysis of how deploying waste-to-energy systems is dependent on cross-cutting research methods, including geographical information systems and big data. It is a useful resource for professionals working in waste-to-energy technologies, as well as those in the food industry and food waste management sector planning and implementing these systems, but is also ideal for researchers, graduate students, energy policymakers and energy analysts interested in the most recent advances in the field. Provides guidance on how specific food waste characteristics drive possible waste-to-energy conversion processes Presents methodologies for selecting among different waste-to-energy options, based on waste volumes, distribution and properties, local energy demand (electrical/thermal/steam), opportunities for industrial symbiosis, regulations and incentives and social acceptance, etc. Contains tools to assess potential environmental and economic performance of deployed systems Links to publicly available resources on food waste data for energy conversion
