Introduction Solid waste management is an issue that must be addressed by every community in the U.S. The demand for waste management strategies that are protective of the environment has increased due to heightened environmental awareness and major evolution in both environmental policy and regulation over the last 20-30 years. Unfortunately, the quantities of waste that require management hav...

In July 1987 and January 1988, forty-six percent (441/955) of randomly selected US hospitals responded to a questionnaire intended to identify their waste disposal practices. Survey responses were received from hospitals in 48 states. United States hospitals generated a median of 6.93 kg of hospital waste per patient per day and infectious waste made up 15% of the total hospital waste. Most hos...

The increased concern about environmental problems caused by inadequate waste management, as well as the concern about global warming, promotes actions toward a sustainable management of the organic fraction of the waste. Landfills, the most common means to dispose of municipal solid waste (MSW), lead to the conversion of the organic waste to biogas, containing about 50% methane, a very active ...

Hazardous waste management incorporates collection, separation, treatment, recycling and disposal of hazardous wastes. In this paper, a new multi-objective mixed integer model is presented for hazardous waste collection problem. The model aims to minimize transportation and construction costs, and environmental and population risks in hazardous waste management systems. This model is applied in...

The economic, social and environmental costs of food waste are being increasingly recognised. Food waste consists of both edible and inedible components. Whilst wastage of edible food is problematic for obvious reasons, there are also costs associated with the disposal of the inedible fraction to landfill. This is the third in a series of papers examining the costs of food waste throughout the ...

This paper aims to compare household waste, separated pig solids, food waste, pig slaughterhouse sludge and green algae regarding their biodegradability, their stabilization kinetics and their temperature rise during composting. Three experiments in lab-scale pilots (300 L) were performed for each waste, each one under a constant aeration rate. The aeration rates applied were comprised between ...

The total production of plastics is currently more than 230 million tonnes/year, which will increase to 400 million tonnes in 2020, based on a very conservative growth rate of about 5% per year [1, 2]. The increasing consumption of polymer products, in various fields, generates a large quantity of waste materials, which equates to more than 12% of the urban solid waste stream [3]. Therefore, th...

Distillery waste disposal is one of the major problems being faced by all nations across the globe. To diminish its organic loading, the distillery waste is treated before its final disposal by biological processes. Microalgae pond gives a way to solve this situation. An evaluation of the performance of a laboratory-scale microalgae pond treating distillery waste previously treated in an anaero...

Background: Food waste is a very serious problem, it is proven that Indonesia is the second largest producer of food waste in the world. A limited waste management system will result in a decrease in environmental quality such as air pollution, water pollution, and soil pollution. So far, the waste management system is only limited to reducing waste generation. Life Cycle Assessment (LCA) is a ...
