Sewage sludge production increases continuously reaching almost 20% (946 700 t 1 118 795 tons of dry matters in 2007) during the (directly or after composting). The remaining 30% was incinerated (with or without household wastes) or landfilled. Nowadays, sludge reduction is a major concern. This activity has to becom be careful to the environmental impacts of sludge treatment and disposal route...

The Hazardous Material Removal Program will provide all academic departments and faculty with the opportunity to dispose of unneeded hazardous chemicals and radioactive material with no EH&S recharge. The disposal program will be organized building by building and advanced notice will be given to each department. Radioactive waste and materials along with routine chemical waste will be collecte...

In this edition of the Journal of Hospital Infection, Kanemitsu et al. report their findings from laboratory studies intended to evaluate the efficacy of incineration as a method for sterilization of clinical wastes. High-temperature incineration is regarded as a wholly effective ‘gold standard’ method for the sterilization of wastes, although few attempts have been made to obtain ‘proof of pro...

Electronic waste or e-waste is one of the emerging problems in developed and developing countries worldwide. It comprises of a multitude of components with valuable materials, some containing toxic substances, that can have an adverse impact on human health and the environment. Previous studies show that India has generated 0.4 million tons of e-waste in 2010 which may increase to 0.5 to 0.6 mi...

56 Waste Alternatives / Waste-to-Energy of the town’s wastes are burned in antiquated incinerators, but these lack pollution controls and are subject to continual breakdowns. Huntington can’t look to neighboring communities for help; most of those communities have similar problems. When looking for a solution to its disposal situation, Huntington N. El’s integrated approach to solid waste manag...

Why recycle? The most commonly stated reason for recycling is to reduce burdens associated with the disposal of our never-ending stream of wastes. Waste disposal potentially causes air and water pollution and is costly; moreover, landfi lls compete with other land uses. In addition, recycling can extend our supply of materials to alleviate scarcity and to moderate rising prices of raw materials...

4. With an aim to improve the waste management, Mongolia developed the following regulations: “A rule on classification, collection, temporary storage, transportation, treatment of hazardous wastes” (2002); “Regulation and procedures on disposal and landfill of hazardous waste of business entities, and requirements on waste containers and waste disposal sites” (2006); “Methodology for calculati...

The anoxic, alkaline hydrolysis of cellulosic materials generates a range of cellulose degradation products (CDP) including α and β forms of isosaccharinic acid (ISA) and is expected to occur in radioactive waste disposal sites receiving intermediate level radioactive wastes. The generation of ISA's is of particular relevance to the disposal of these wastes since they are able to form complexes...

The usual two types of town wastes, viz. rubbish (katchra) and night-soil, are dealt with separately in their sanitary disposal. In most municipal towns in this province, katchra is stacked in heaps above ground, and near the outskirts of the town. Our observations have shown that it is as much a source of fly nuisance as the night-soil, but very little attention is paid to its sanitary disposa...

This paper proposes a model for obnoxious waste location-routing problem (LRP) considering various types of wastes and several treatment technologies. The investigated distribution network includes three echelons of generation nodes, treatment and disposal facilities. A multi-objective LRP model is developed with three objective functions minimizing the treatment and disposal facility undesirab...
