Socioeconomic and Environmental Implications of Agricultural Residue Burning


Book Description

This book discusses the important issue of the socioeconomic and environmental impacts of agricultural residue burning, common in agricultural practices in many parts of the world. In particular, it focuses on the pollution caused by rice residue burning using primary survey data from Punjab, India. It discusses emerging solutions to agricultural waste burning that are cost-effective in terms of both money and time. The burning of agricultural residue causes severe pollution in land, water and air and contributes to increased ozone levels and climate change in the long term. However, appropriate assessments have not been undertaken so far to demonstrate the relevant impact of agriculture-based pollution, especially residue burning. This book addresses this gap in the literature. Punjab has been used as a case study as it is the chief granary of India, contributing to 27.2 percent of the Indian national produce of rice and 43.8 percent of wheat. It is presumed that the findings from this state will be useful not only for other agricultural areas in India, but across the world. This book, therefore, sensitizes policy makers, researchers and students about the impacts of air pollution caused by agricultural residue burning---a subject not much dealt in the literature---and provides a way forward.




Managing Agricultural Residues


Book Description

Many agriculturalists, conservationists, and environmentalists are stressing the importance of sustaining soil productivity so that future generations will have adequate productive land on which to produce food. One significant factor affecting soil productivity is the retention of crop residues on the surface of the soil to help control soil erosion. This book provides a review of the vast amount of literature on the subject, condensing the findings in a comprehensive, easy-to-understand manner. It focuses on topics such as erosion control, crop production in systems involving surface residues, residue use for fuel and animal feed, plant pathogens, insects, soil properties, and the economics of conservation tillage.




Agricultural Waste and Residues


Book Description

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.

Soil Management


Book Description

Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.

Beneficial Co-Utilization of Agricultural, Municipal and Industrial by-Products


Book Description

Co-utilization or blending of residuals offers a unique opportunity to develop products with particular characteristics that are able to target specific customer needs. The very notion of deliberately blending by-products suggests that the recycling and beneficial reuse industries are taking a quantitative step forward towards developing products rather than simply reusing residuals. At the same time that this step provides unique opportunities, it also presents unique challenges. The science associated with the beneficial use of one product may not apply when that product is mixed with another residual. Blending of materials may alter the chemistry of the components of the mixture. This may offer additional benefits, as in the case of disease suppression in composts, or present unexpected problems, as the use of lime-stabilized biosolids has done in Maryland. This book consists of the proceedings of the Beltsville Symposium. The organizers of the Symposium attempted to structure a meeting that would outline both the potential benefits of co-utilization as well as concerns. The editors have divided the proceedings into sections that describe the practical basis for co-utilization of residuals as well as the potential benefits. Specific considerations are described. Finally, case studies include descriptions of successful operations and data that detail results of research involving co-utilization materials. Blending of materials for specific objectives needs to be the focus of any successful co-utilization effort. The scientific implications of the mix need to be determined before a product can be used properly.




Handbook of Waste Management and Co-Product Recovery in Food Processing


Book Description

The intensification of agriculture and food production in recent years has led to an increase in the production of food co-products and wastes. Their disposal by incineration or landfill is often expensive as well as environmentally sensitive. Methods to valorise unused co-products and improve the management of wastes that cannot be reused, as well as techniques to reduce the quantity of waste produced in the first place, are increasingly important to the food industry. With its distinguished editor and array of international contributors, Waste management and co-product recovery in food processing reviews the latest developments in this area and describes how they can be used to reduce waste.The first section of the book provides a concise introduction to the field with a particular focus on legislation and consumer interests, principle drivers of waste management. Part two addresses the minimisation of biowaste and the optimisation of water and energy use in food processing. The third section covers key technologies for co-product separation and recovery, such as supercritical fluid extraction and membrane filtration, as well as important issues to consider when recovering co-products, such as waste stabilisation and microbiological risk assessment. Part four offers specific examples of waste management and co-product exploitation in particular sectors such as the red meat, poultry, dairy, fish and fruit and vegetable industries. The final part of the book summarises advanced techniques, to dispose of waste products that cannot be reused, and reviews state of the art technologies for wastewater treatment.Waste management and co-product recovery in food processing is a vital reference to all those in the food processing industry concerned with waste minimisation, co-product valorisation and end waste management. - Looks at the optimisation of manufacturing procedures to decrease waste, energy and water use - Explores methods to valorise waste by co-product recovery - Considers best practice in different sectors of the food industry
