Abstract:
... Environmentally friendly waste management (EFWM) is a safer way of waste disposal that can foster a cleaner environment for both farms and their surroundings. It may lessen land, air, and water pollution, as well as moderate ecological footprints, and aid in sustainable agricultural development, which has become one of the major concerns of the modern era. To achieve these outcomes, incentives and ...

Abstract:
... Wastewater from the livestock industries contains high concentration of nutrients, organic pollutants, suspended solids, and pathogenic microorganisms. Discharge of livestock wastewater without proper treatment can therefore cause serious pollution, calling for advanced treatment methods. For instance, electrochemical treatments are gaining attention because they are clean and flexible. Compared t ...

Abstract:
... The distribution of heavy metal concentrations and related human health risks were investigated for Shimabara City, Nagasaki Prefecture. The purpose was to clarify the potential for heavy metal contamination in an area already known to be affected by nitrate pollution. A total of 188 soil samples was collected at 47 sites. The heavy metal content of the soil was measured in laboratory using an X-r ...

Abstract:
... Wild carnivores are threatened by human activities, particularly by lethal responses to livestock predation. As natural prey populations decline, predation of livestock and consumption of discarded livestock ‘waste’ (carcasses and body parts) should increase. We investigated whether parameters linked to the production of livestock waste affected the likelihood of livestock predation. We interviewe ...

Abstract:
... Currently, some regions have low access to electricity services, which prevents the affected population from having an adequate standard of living. The human development index (HDI) is an indicator that measures the degree of progress in a country according to the quality of life for the population and the access to electricity has been related to the increase in HDI. A mathematical optimization m ...
... The composite material was made by assembling chitosan and chicken feather fibers. The chitosan with 83% of deacetylation degree was extracted from shrimp crustaceans with chemical treatments. The composites were produced with treated and untreated fibers. The reinforcements were undergone to an alkali treatment, varying the soaking time 2 h, 4 h and 6 h. The biopolymer was analyzed by physical–ch ...
... Large quantities of natural and synthetic hormones contained in livestock waste and wastewater (LWW) can cause serious problems in our environment. Composting and anaerobic digestion cannot remove hormones efficiently, so they should be modified to enhance the treatment processes. In addition, constructed wetlands show decent rates for removal of hormones. Advanced technologies such as membrane bi ...

Abstract:
... Urbanization and agriculture are two key factors that place demands on water resources and serve as sources of anthropogenic pollution into inland waterways. The San Antonio River, which is sourced from a karst aquifer, plays an important recreational and scenic role, yet effective management is often hampered by the lack of understanding of the chemical characterization of the water system. The k ...

Abstract:
... While wastewater has been found to harbor SARS-CoV-2, the persistence of SARSCoV-2 in stormwater and potential transmission is poorly understood. It is plausible that the virus is detectable in stormwater samples where human-originated fecal contamination may have occurred from sources like sanitary sewer overflows, leaky wastewater pipes, and non-human animal waste. Because of these potential con ...

The method of collection included digging and hand sorting from the 9 ecosystems and 31 blocks and six districts. The samples were collected from 139 sampling sites which include canal border, area for household and animal waste disposa ...

Abstract:
... The production of non-fish based docosahexaenoic acid (DHA) for feed and food has become a critical need in our global context of over-fishing. The industrial-scale production of DHA–rich Thraustochytrids could be an alternative, if costs turned out to be competitive. In order to reduce production costs, this study addresses the feasibility of the non-axenic (non-sterile) cultivation of Aurantioch ...
... De-carbonized energy implementation involves experts to integrate inter-connected strategic objectives. Pragmatic sustainable development requires substitution of fossil-fuel energy with cleaner energy. Simultaneously, demonstrating circular economy through waste-to-energy concept is another perspective to foster renewable energy resources. Biomass energy has the highest share in the renewable ene ...

Abstract:
... The utilization of livestock waste has attracted increasing attention in recent years. The presence of high levels of heavy metals is a major obstacle to the utilization of biogas as a fertilizer resource. In this study, the heavy metal contents in biogas residue, slurry, and discharged sewage from three representative farms of gooseries, henneries, and dairy farms in the Yangtze River Basin were ...

... Sustainable crop and livestock planning encounter serious challenges when tasked with reducing the associated nutrient pollution entering the watershed environment. To overcome these challenges, approaches for specifying optimal crop pattern and livestock distribution to limit the pollution in the catchment are advised. In this research, a simulation–optimization approach is used in which the Soil ...
... The increase in livestock production creates a serious problem of managing animal waste and by-products. Among the wide range of waste valorization methods available, anaerobic digestion is very promising. It is a form of material recycling that also produces renewable energy in the form of biogas, which is reminiscent of energy recycling. The effluent and digestate from the anaerobic digestion pr ...

Abstract:
... Livestock operations have been highly intensified over the last decades, resulting in the advent of large concentrated animal feeding operations (CAFOs). Intensification decreases production costs but also leads to substantial environmental impacts. Specifically, nutrient runoff from livestock waste results in eutrophication, harmful algal blooms, and hypoxia. The implementation of nutrient recove ...
