The management of the 86,388.00 tons of solid wastes generated every day in Mexico is a complicated matter. In order to help solve this problem, sustainable buildings that include solid waste management plants and community awareness programs are being constructed. The objective of this research is to propose the building of a reception and storage center for storing the economically valuable w...

Available sources of portable water for drinking, domestic and industrial chores in Nigeria are dwindling because of concomitant increase in population, urbanization and industrial activities. This study assessed the qualities of Surface Water (SW), Sediment (SD) and Tilapia Fish (Oreichromis niloticuss) (TF) samples collected from Asejire, Oni, Ona, Ogun, Ogunpa, Eleyele and Majidun rivers and...

This paper summarizes a natural resource damage assessment for the State of Montana. Mining wastes have caused significant reductions in trout stocks in a 145-mile stretch of Montana's Silver Bow Creek and Clark Fork River. To estimate economic damages from decreases in catch rates, we develop and estimate an individual-based utility-theoretic model of where and how often an angler will fish as...

In acute toxicity (96 hr) experiment the fingerlings of freshwater fish Labeo rohita was exposed to tannery, electroplating and textile mill effluents. The LC0 and LC50 concentrations were 15% and 20% for tannery effluents, 3% and 6% for electroplating effluents and 18% and 22% for textile mill effluents respectively. It was found that, electroplating effluent was more toxic than tannery and te...

Industrial wastes are considered critical factors for disturbing the natural environment. Composite effluents tainted with different heavy metals are major environmental pollutants of varied wetland ecosystems (Wong 2003). Spread over 12 500 ha, The East Calcutta Wetlands, a Ramsar site in West Bengal, India (lat 22°33 ́ –22°40 ́N, long 88°25 ́–88°35 ́E), receives industrial runoff from at least 60...

The efficient large-scale recycling of plastic waste is of increasing interest from an ecological and economic point of view but it represents a goal that has yet to be achieved by the recycling industry. The W2Plastics project aims at a fundamental change of the present status of plastics recycling by creating a breakthrough technology for the recycling of polyolefin’s from complex wastes, i.e...

Τhis study focuses on the exploitation of food-industry wastes as a source for hydrogen production. The wastes which were used were out of date solid baby foods at seven different flavors (solid wastes) and a glucose-based syrup (liquid waste). Preliminary batch hydrogen experiments at mesophilic conditions and initial carbohydrates concentration of 5 g/L were performed to assess the hydrogen p...

UNLABELLED Ammonia emissions were quantified for the laboratory-scale composting of three typical organic wastes with medium nitrogen content: organic fraction of municipal solid wastes, raw sludge and anaerobically digested sludge; and the composting of two wastes with high nitrogen content: animal by-products from slaughterhouses and partially hydrolysed hair from the leather industry. All th...

Medical establishments play important roles in different activities by using of modern technology to serve the humans and the environment through different departments in the establishment and its firms. Medical wastes are considered as a hazardous waste because they contain toxic materials, infectious, or non-infectious wastes and they are considered as a hazard to millions of patients, health...

Kuhlman, L.R., 1990. Window composting of agricultural and municipal wastes. Eur. Symp. on Integrated Resource Recovery from Municipal Solid Wastes. Resour. Conserv. Recycl., 4: 1 5 1 160. Many wastes are produced from agricultural and municipal facilities that are not suitable for direct land application. Composting these wastes converts them to a humus-containing organic material advantageous...
