Available in PDF, EPUB and Kindle. Book excerpt: Global demand for mineral fertilizers is continuously increasing, while large amounts of organic wastes are being disposed without use as a resource, resulting in soil, water and air pollution. Current trends of intensification, expansion and agglomeration of livestock production result in a net import of nutrients that lead to a surplus in some production areas. Therefore, new processes and technologies to recover and re-use nutrients from both solid and liquid wastes are desirable to close the loop on the nutrient cycle in modern human society and address future scarcity of non-renewable nutrients and fossil-based fertilizers. This Research Topic aims to present scientific progress regarding processes and technologies that allow recovery and re-use of nutrients from wastes, the selective recovery of mineral nutrients (ammonia and phosphates), the production of new organic fertilizers, and evaluation of their relative agronomic efficiency. The articles within provide a stronger recognition of the importance of nutrient recovery and upcycling in the new horizons of the circular economy.

Download or read book Industrial Farm Animal Production the Environment and Public Health written by James Merchant and published by JHU Press. This book was released on 2024-09-24 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essential essays on the environmental impacts of factory farms on public health. The rapid—and relatively recent—concentration of food animal production into factory farms makes meat plentiful and cheap, but this type of agriculture comes at a great cost to human health and the environment. In Industrial Farm Animal Production, the Environment, and Public Health, editors James Merchant and Robert Martin bring together public health experts to explore the most critical topics related to industrial farm animal production. The environmental impacts of these concentrated animal-feeding operations endanger the health of farm and meatpacking workers, neighbors, and surrounding communities. Factory farms create public health hazards such as antibiotic-resistant bacteria due to the overuse of antibiotics in livestock, as well as water polluted with nitrates, microbes, and other harmful chemicals. Despite the clear need for greater worker protection and oversight to mitigate the environmental harms of these practices, factory farms are notoriously difficult to regulate. Industrial animal operations are located predominantly in rural areas, often next to poor communities and communities of color. Food companies have driven independent producers nearly to extinction, sapped the economic vitality of rural communities, and amassed sweeping political influence at both the state and national levels to effectively prevent mitigation efforts. Essays in this volume cover pertinent topics such as the history, structure, and trends in the factory farming industry; water and air pollution; infectious disease health effects; community and social impacts; environmental justice and sustainable agriculture; and the impacts of COVID-19 among meatpacking workers.
