Currently, Construction and Demolition waste (C&D waste) is a worldwide issue that concerns not only the construction management level of on-site managers but also the sustainable development of construction industry. In this paper, detailed formulas are listed for calculating the costs of three typical kinds of disposal routes of C&D waste. They are Landfill Disposal, Recycling and Reuse. Usin...

Purpose: Considering the UK’s limited capacity for waste disposal (particularly for hazardous/ radiological waste) there is growing focus on waste avoidance and minimisation to lower the volumes of waste being sent to disposal. The hazardous nature of some waste can complicate its management and reduction. To address this problem there was a need for a decision making methodology to support man...

The report by the National Academy of Science Committee on Institutional Considerations in Reducing the Generation of Hazardous Industrial Waste examines key institutional, or nontechnical, factors that affect the generation of hazardous waste by industry. It provides a framework for evaluating public policies, both regulatory and nonregulatory, to reduce the generation of hazardous waste. The ...

The production of poly β-hydroxybutyrate (PHB) by Bacillus subtilis NG220 was observed utilizing the sugar industry waste water supplemented with various carbon and nitrogen sources. At a growth rate of 0.14 g h(-1) L(-1), using sugar industry waste water was supplemented with maltose (1% w/v) and ammonium sulphate (1% w/v); the isolate produced 5.297 g/L of poly β-hydroxybutyrate accumulating ...

Harmful effects of textile industry effluents are a huge problem for now a days. It creats many problems at different level of ecosystem. The textile industry generates a high volume of waste products. Approx. seventy tons of dye is used annually. A big portion of such amount is discharged in a huge amount of water which affects the quality of water. They are cause of high BOD, COD sulphate, lo...

In the first phase of this study, the work has focused on the collection of data exploiting the state of existing knowledge. Review of literature on occupational and environmental exposures and related health outcomes in solid waste management systems is conducted. Reports are collected from several reliable sources at the national, state, and local levels from both public and private utilities...

An activated carbon as adsorbent is derived from waste tendu leaves (Diospyros melanoxylon) from local Beedi (Cigarette) industry for removal of sulphur dye from textile waste water. Tendue leaves were chemically treated with sulphuric acid and activated carbon prepared was analyzed by pH, moisture content, ash content, bulk density and BET surface area. The adsorption studies were performed as...

The principal use of water by the petroleum refining industry in the United States of America is in the refining branch itself, and the present paper is concerned with problems arising from this use of water, and some of the measures being taken by the industry to solve these problems. The compilation oftheManualonDisposalof Refinery Wastes is briefly alludedto, and the importance ofrecirculati...

T he sustainability movement received yet more encouragement and took another baby step as students at Princeton University led a campus-wide adoption of 100% post-consumer-waste paper (PCW) for the New Jersey campus’s use in copiers and information technology printers. “Leave it to the young,” an uncourageous mantra of many in the environmental movement, may be beginning to actually pay off as...

The cement industry has the potential to become a major consumer of recycled waste materials that are transformed and recycled in various forms as aggregates and pozzolanic materials. These recycled waste materials would otherwise have been dumped in landfill sites, leaving hazardous elements to break down and contaminate the environment. There are several approaches for the reuse of these wast...
