The identification and classification of plastics plays an important role in waste management and recycling processes. Present electrical and optical sorting techniques lack the required resolution for accurate identification in a high throughput manner for a diverse set of plastics commonly found in municipal waste. In this work a multi-spectral infrared spectroscopic technique is employed to ...

This study employed contingent valuation method to estimate the willingness to pay (WTP) of the households to improve the waste collection system in Kuala Lumpur, Malaysia. The objective of this study is to evaluate how household WTP changes when recycling and waste separation at source is made mandatory. The methodology consisted of asking people directly about their WTP for an additional wast...

Growth of the population and of industrialization, and substandard disposal of the increased waste products thus generated, have resulted in numerous documented cases of harm to human, plant, and animal health. The Resource Conservation and Recovery Act (1976), its stated goals, and its intended means of implementation, are discussed relative to hazardous waste problems. Subtitle C of this Act,...

Annually more than 80% of the overall budget of the uran solid waste management system in Iran is allotted to collection and transportation of the solid wastes. The main objective of the current study is to evaluate the external costs associated with solid waste collection, transfer, and transportation in Tehran for the period of 2018 to 2032 based on the current situation. Waste guidance syste...

this experiment was conducted in order to study the influence of different levels of municipal solid waste compost and nitrogen rate on grain quality of sweet corn (zea mays l. saccharata) and some soil properties under marvdasht conditions during growing season of 2008-2009. the experiment was arranged as split plots based on a randomized complete block design with two factors and three replic...

Insight into the health risk awareness levels of e-waste workers is important as it may offer opportunities for better e-waste recycling management strategies to reduce the health effects of informal e-waste recycling. Therefore, this study assessed the knowledge, attitude, and practices associated with occupational health risk awareness of e-waste workers compared with a control group (butcher...

The purpose of this paper is to study the impact of ISO 14001 and other significant factors on solid waste generation rates of organizations. The research is based on a survey conducted on a random sample of industrial companies that operate in United States. The paper reveals that companies’ solid waste generation rates are significantly reduced by certification and identifies several factors ...

background: monitoring of indicator and pathogenic microorganisms is essential for proper composting. the aim of this study was to evaluate the change in population of coliform bacteria and salmonella spp. in composting process of municipal wastes and after its application on soil. methods: the samples were taken from each raw waste pile, initial pile, and active phase pile, cooling phase pile ...

geotechnical investigations of waste fills are rarely undertaken, and consequently the geotechnical community has little knowledge of their engineering properties. in this study, a geotechnical testing program was conducted to evaluate the engineering properties of old municipal solid waste sampled in whamyung msw landfill site, busan, korea. the conducted tests included water content, specific...

tehran has a population of over 12 million and produces more than 7500 tons of waste every day. tehran’s municipal solid waste is processed and landfilled at kahrizak disposal center. due to inappropriate waste management, a lake with a leachate volume of 180,000m3 has been formed. to solve this problem a leachate treatment plant is currently under construction. a byproduct of leachate treatmen...
