Large-scale production of antibiotics began in the 1940’s. Almost immediately, the use of antibiotics spread to agricultural uses. In livestock, antibiotics are used to reduce illness. However, a far more common use is to increase feed efficiency, resulting in better profits. (Coghlan, 1996 and Bonner, 1997) With the widespread use of antibiotics has come a variety of concerns. Primarily, fear ...

Reuse of agricultural wastes and industrial by-products for building materials has been gaining popularity in the recent years. Agricultural waste material; namely rice husk ash (RHA), and industrial by-product; namely expanded polystyrene beads (EPS) are discarded in large amounts globally, causing increased environmental problems. Therefore, this paper introduces innovative efforts of the com...

mass generation of bagasse wastes from every 100 kg of sago starch pith being processed are likely to pollute the water when they are discarded into rivers. the increase of livestock production increases manure production and improper management of these manures will pollute the soil and environment, and causing diseases outbreak. co-composting of sago bagasse and chicken manure could serve as ...

Backyard poultry ownership provides a great opportunity for improved self-reliance and small-scale agricultural sustainability through home egg and meat production. One issue with backyard poultry ownership is managing the waste products of your birds, particularly the manure and bedding mixture (termed “litter”) that builds up in the coop. If not managed properly, this waste material can creat...

The recycling of rural and urban organic waste materials onto agricultural land provides a challenge to the producers and end-users who both have a 'duty-of-care' to ensure the method of disposal is managed in a sustainable way. Careful management means that soil and water resources are not contaminated, the agricultural production system remains stable, and land use alternatives remain availab...

this study reports the removal of cadmium from wastewater in batch mode, using two carbonaceous adsorbents viz. sunflower head carbon (shc) and sunflower stem carbon (ssc) prepared from waste biomass of sunflower. the adsorbents were characterized by fourier transform infrared spectroscopy (ft-ir), scanning electron microscopy (sem) and energy dispersive x-ray analysis (edx). the results of bat...

Materials Research Group (CMRG) at the University of Mississippi (UM) have recently begun a research study supported by the U. S. Department of Agriculture (NRICSREES-USDA Award number 2003-35504-13627) examining natural fiber reinforcements (NFR). The objectives of this research are to demonstrate the feasibility of using the cost-effective pultrusion process to manufacture high quality polyme...

This paper is discussed the Anhui agricultural industrialization using the method of principal component analysis. The indexes include per capita net income of farmers in Anhui province, non-agricultural employment rate, urbanization rate, the total power of agricultural mechanization, universal ratio of rural water, car villages, the proportion of industrial waste water by sewage treatment in ...

A Publication of the Association for Iron & Steel Technology Ironand steelmaking processes present a largely untapped opportunity to transform some of the world’s most problematic waste streams into raw materials for production. This opportunity lies in their high-temperature environments, which offer sustainable pathways for utilizing chemical reactions to repurpose waste materials as resource...

A geographic information system (GIS) based manure application plan has been developed for the site-specific application of animal waste to agricultural fields in the Westbrook sub-catchment of the Murray-Darling Basin, south-east Queensland, Australia. Sites suitable for animal waste application were identified using a GIS based weighted linear combination (WLC) model. The degree of land suita...
