The use of different agricultural or industrial wastes is an important component of sustainable agriculture in order to close nutrient cycles on a global, regional and local scale. Farmyard manure or slurry are established as fertilizers in agricultural or horticultural production and substitute mineral fertilizers. Due to the lower nutrient use efficiency compared with mineral fertilizers, esp...

How Much Waste is Wasteful? Although medical and infectious wastes are often highlighted in evaluations of Hospital Solid Waste Composition a hospital’s waste stream, these hazardous wastes constitute only 15% of a hospital’s total waste generation. The remaining 85% of a hospital’s waste, which is Other 10% Wood 3% Glass 7% Plastics 15% Food 10% Metals 10% Paper 45% considered to be nonhazardo...

The aim of this study was evaluate the potential use of low-cost and environment friendly solvents to extract polyphenols from apple wastes for biotechnological application. Apples solid wastes from industrial transformation were used as raw material to produce extracts enriched in antioxidant polyphenols, using a green and environmental friendly solvent in a solid-liquid extraction. The reacti...

Arsenic exposures contribute significantly to the burden of preventable disease worldwide, specifically related to increased risks of cancer, diabetes, and cardiovascular disease. Most exposures are associated with natural contamination of groundwater, which is difficult to mitigate when these sources are used for drinking water. An anthropogenic source of arsenic exposure stems from the widesp...

Lemus, G.R. and Lau, A.K. 2002. Biodegradation of lipidic compounds in synthetic food wastes during composting. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 44: 6.336.39. Changes in food production, consumption patterns, and more restrictive regulations, result in larger quantities and higher diversity of waste materials that need to be treated and disposed. Organic wastes...

Introduction During this research project, we attempted to identify and overcome barriers and resistance to the establishment of organic waste (leaf and yard waste and food waste) collection and diversion programs within public and private institutions in the region that generate large amounts of organic wastes. As only 2.4% of food waste (EPA 1997) is recovered or recycled, there is 97.6% of f...

The analysis of the ~5.8-Mb draft genome sequence of a moderately thermophilic, heterotrophic, facultative anaerobic bacterium, Paenibacillus strain P1XP2, identified genes for enzymes with the potential for degrading complex food wastes, a property consistent with the ecological habitat of the isolate.

Dietary inadequacy and nutrition-related non-communicable diseases (N-NCDs) represent two main issues for the whole society, urgently requesting solutions from researchers, policy-makers, other stakeholders involved in health food system. Food by-products wastes (FBPW) a global problem of increasing severity, widely recognized as an important unsustainability hotspot, with high socio-economic e...

Reduction of food waste provides important environmental and economic benefits. Valorization by-products into edible materials is one the most interesting strategies in this field. However, wastes can contain chemical contaminants or potential pathogens that may endanger consumers’ health. Therefore, assuring quality safety these utmost importance to take advantage valorization strategy. In rev...

A prototype in-vessel composting unit, which includes air circulation and misting systems, was designed and built as a senior capstone project at the Bio-Resource Engineering Department at the University of Maine. The university Office of Resource Conservation and Recovery initiated a recycling program for postconsumer food waste generated by the residence hall commons areas in 1991. This food ...
