The construction, demolition and excavation waste arising in England was estimated at 91 million tonnes in 2003. The current thinking on construction waste minimisation is heavily focussed on several issues relating to physical construction waste and recycling guides. Indeed, much had been published on ways to improve on-site waste management and recycling activities but very few attempts made ...

Pathology, microbiology, blood bank and other diagnostic laboratories generate sizable amount of biomedical waste (BMW). The audit of the BMW is required for planning proper strategies. The audit in our laboratory revealed 8 kgs anatomical waste, 600 kgs microbiology waste, 220 kgs waste sharps, 15 kgs soiled waste, 111 kgs solid waste, 480 litres liquid waste along with 33,000 litres per month...

the usage of turbochargers in diesel engines has led to the downsizing of the motors as well as usage of the waste gates in turbochargers. any dimensional reduction in turbochargers and appurtenant leads to an enhancement on the performance of internal combustion engines and in environmental problems in terms of aerodynamic, thermodynamic and mechanical specifications for both engines and turbo...

Introduction: Optimization of waste collection systems can reduce waste management costs. In this study, optimization of the waste collection system of district 3 of Yazd municipality of Iran has been investigated using underground containers. Materials and Methods: In this research, after collecting information and performing field inspections, the statistical and raster information obtained ...

Building industry as one of the greatest industries in Iran comprises a significant share of waste generation in the country. Since a large quantity of the generated construction waste is buried due to the lack of a recycling protocol, it leads to an undesired waste of resources and causes severe environmental issues. This paper provides a study on the problem of material loss/construction wast...

The energy demand in India is increasing substantially and the energy supply is not in pace with demand. The recovery of energy from waste material is one of the best methods to tackle the energy crisis. The potential for recovery of energy from urban waste is high in Maharashtra followed by Uttar Pradesh, Tamil Nadu and West Bengal. In this paper, anaerobic digestion method is used to find the...

The environmental impact caused by teaching and research with regard to chemical waste is of increasing concern, and attempts to solve the issue are being made. Education and research-related institutions, in most laboratory and non-laboratory activities, contribute to the generation of small quantities of waste, many of them highly toxic. Of this waste, some is listed by government agencies wh...

Waste treatment facilities are often shared among different municipalities as a means of managing wastes more efficiently. Usually, management costs are assigned to each municipality depending on the size of the population or total amount of waste produced, regardless of important environmental aspects such as per capita waste generation or achievements in composting or recycling. This paper pr...

BACKGROUND This paper presents the findings of a 13-month lean implementation in National Health Service (NHS) primary care health visiting services from May 2008 to June 2009. METHOD Lean was chosen for this study because of its reported success in other healthcare organisations. Value-stream mapping was utilised to map out essential tasks for the participating health visiting service. Stake...
