the construction industry is a major consumer of new materials. given that material production for construction work accounts for a significant percentage of all energy consumed nationally in newly developing countries, it becomes vital that the construction industry strives to reduce waste at all stages of construction. however, the importance of these construction wastes in terms of types and...

the purpose of this research was to evaluate the recovery potential of solid waste in mashhad. the solid waste generated in the regions 4, 5 and 6 has been quantified and characterized using direct weighing, physical testing and truckload sampling methods. to determine the quantity and quality of waste generated and its seasonal variations, chemical and physical analysis were carried out for on...

9 Variations in solid waste composition data are necessary as inputs to solid waste 10 planning, yet uncertainty exists regarding which probability distributions might be 11 generally valuable to describe the variability. Twenty-two detailed analyses of solid 12 waste from British Columbia, Canada, are fit to distributions using the BestFit 13 software. Alternative distributions are ranked base...

Management of municipal solid waste (MSW) has become a significant environmental problem, especially in fast-growing cities. The amount of waste generated increases each year and this makes it difficult to create solutions which due to the increase in waste generation year after year and having to identify a solution that will have minimum impact on the environment. To determine the most sustai...

Sound waste management and optimisation of resource recovery require reliable data on solid waste generation and composition. In the absence of standardised and commonly accepted waste characterisation methodologies, various approaches have been reported in literature. This limits both comparability and applicability of the results. In this study, a waste sampling and sorting methodology for ef...

A large amount of medical waste is produced during disaster relief, posing a potential hazard to the habitat and the environment. A comprehensive understanding of the composition and characteristics of medical waste that requires management is one of the most basic steps in the development of a plan for medical waste management. Unfortunately, limited reliable information is available in the op...

The current study aims to analyze waste characteristics and management practices of the hotel industry in Hoi An, a tourism city in the center of Vietnam. Solid wastes from 120 hotels were sampled, the face-to-face interviews were conducted, and statistical methods were carried out to analyze the data. The results showed that the mean of waste generation rate of the hotels was 2.28 kg/guest/day...

As the need for a more circular model is being increasingly pronounced, a fundamental change in the end-of-life (EoL) management of electrical and electronic products (e-products) is required in order to prevent the resource losses and to promote the reuse of products and components with remaining functionality. However, the diversity of product types, design features, and material compositions...
