This paper proposes that industrial waste be regarded, in a business economic sense, as having the same basic status as regular products. A basic mathematical expression for assigning industrial costs to waste is presented. The expression can be employed in conjunction with cost-benefit analysis for estimating the “true” internal costs of industrial waste. In two case studies presented, industr...

Current hazardous waste disposal policies in the Home Health Care setting were evaluated as it related to the need for better regulation of hazardous materials entering residential waste streams. It was found that all waste materials from home care visits with the exception of “sharps,” were placed directly into residential waste streams. Therefore, large volumes of potentially hazardous waste ...

The metal fmishing industry uses over 40 production processes to produce a wide range of metal products. Waste streams generated include wastewater, waste oils, spent solvents, and spent process solutions. Current1,v a wide variety of techniques which minimize waste are available. Cost-effective methods to reduce electroplating wastewater contamination include water conserv&ion and drag-out red...

The main aims of solid waste management are to protect the environment and human health; and, to conserve natural resources. However, increasing consumption, environmental issues and resource depletion threaten its sustainability. Solid waste management policies usually fail to reduce consumption, decrease environmental impacts, conserve raw materials and develop sustainable products. These pro...

This paper represents a detailed assessment on raw material waste generation of a semi-automated powder filling and packing process by applying certain quality tools such as Pareto Analysis and Fishbone Diagram. The aim of this study is to identify the sources or categories of raw material waste and analyse its underlying causes. Waste generation is an unavoidable incident in any production pro...

On behalf of the International Solid Waste and Public Cleansing Association (lSWA), it is a pleasure to open this First Annual North American Waste-to-Energy Conference. Solid waste management has moved to the forefront of the environmental agenda. The level of activity and concern by citizens and governments worldwide has reached unprecedented levels. Nations are considering restrictions on pa...

our aim was to make right and informative decision about choosing the most cost-effectiveness heterogeneous infectious waste treatment methods and devices.in this descriptive study, decision tree analysis, with 10-yr time horizon in bottom-up approach was used to estimate the costs and effectiveness criteria of the employed devices at provider perspective in iranian hospitals. we used the one-w...

--------------------------------------------------------ABSTRACT-------------------------------------------------Due to depletion of fossil fuel reserves and increasing cost of the petroleum products are the big troubles of today's world .from past to present, tendency of oil price have increased consecutively. Especially, India has deficient amount of fossil fuel .for this reason, India has to...

background and objectives: hospitals usually generate large amounts of hazardous waste. if not managed properly, hospital waste can pose threats to public safety and damage the environment. waste minimization is a waste management approach that focuses on reducing the amount and toxicity of hazardous wastes. this study pursues a two-fold purpose: 1) to gain insight into hospital waste minimizat...

Solid-state fermentation (SSF) can divert food waste from landfills and produce high-value products. This study was aimed to investigate the feasibility of using SSF and optimize the conditions of production of phytase by Aspergillus ficuum from potato waste. Different parameters including pH of the potato waste, inoculum level, moisture content, incubation period, temperature, and supplementar...
