Waste is a byproduct of human life. Nowadays, municipal solid waste is being produced in excessive amounts and in this way, both developing and developed countries are facing challenges regarding generation of waste. Economic development, urbanization and improved living standards in cities have contributed to increase in the amount and complexity of solid waste produced. The present stud...

This study aimed to identify the metal flow in a municipal solid waste (MSW) management system. Outputs of a resource recovery facility, refuse derived fuel (RDF) production facility, carbonization facility, plastics liquefaction facility, composting facility, and bio-gasification facility were analyzed for metal content and leaching concentration. In terms of metal content, bulky and incombust...

In this study, a dynamic inexact waste management (DIWM) model is developed for identifying optimal waste-flow-allocation and facility-capacity-expansion strategies under uncertainty and is based on an inexact scenario-based probabilistic programming (ISPP) approach. The DIWM model can handle uncertainties presented as interval values and probability distributions, and it can support assessing ...

This paper handles the medical waste disposal facility location problem in Istanbul by using fuzzy TOPSIS (FETOPSIS) to select the adequate place between some candidate points that are obtained from the Ishii’s undesirable facility location algorithm. Medical waste must be disposed without damaging environment and human health, complying with new regulations. The aim is to provide an alternativ...

The paper derives formulas for the energy J(n) that a station’s radio consumes in order to transmit 1 MB of data in an IEEE 802.11 network with n stations. Calculations show that J(n) grows approximately linearly with n, for n ≥ 4. The useful energy consumed in successful transmission and reception of data is constant; the remaining energy is wasted. When n = 15, the waste amounts to 80 percent...

A preliminary study, which establishes the treatment methodology of liquid waste containing sludge and uranium in the lagoon of the conversion facility has been performed. Properties of the liquid waste such as initial water content, density and radiochemical composition were obtained by analyzing the samples taken from the lagoon. In order to minimize the secondary waste resulting from treatme...

a major reason why many developing nations have not made significant advancement in sustainable development (sd) agenda is the neglect of existing building stock which forms the bulk of built assets. although sustainable development is a universal challenge, it cannot be approached in the same way for all nations, but rather practical response can be defined nationally or locally. this paper re...

Treating hazardous-infectious medical waste can be carried out on-site or off-site of health-care establishments. Nevertheless, the selection between on-site and off-site locations for treating medical waste sometimes is a controversial subject. Currently in Iran, due to policies of Health Ministry, the hospitals have selected on-site-treating method as the preferred treatment. The objectives o...
