Electronic waste, or e-waste, is an emerging problem with developed nations as with developing nations. In the absence of proper collection and disposal systems, aware‐ ness, and proper regulations, the problem is rather more acute in developing nations. These wastes are environmentally hazardous on one hand and valuable on the other. They contain substantial amount of metal value, including pr...

Nowadays, the collection of separated solid waste for recycling is still an expensive process, specially when performed in large-scale. One main problem resides in fleet-management, since the currently applied strategies usually have low efficiency. The waste collection process can be modelled as a vehicle routing problem, in particular as a Team Orienteering Problem (TOP). In the TOP, a vehicl...

Waste water treatment facilities clean sewage water from households and industry in several cleaning steps. Such facilities are dimensioned to accommodate a maximum intake. However, in the case of very bad weather conditions or failures of system components the system might not suffice to accommodate all waste water. This paper models a real waste water treatment facility, situated in the city ...

Background & Aims of the Study:  Collection and transportation of municipal solid waste (MSW) for various reasons, especially economic and social are considered as one of the most important elements of the solid waste management system. More than sixty percent of the costs in solid waste management systems in different countries are due to the collection and transportation...

a new, local agro-industrial waste was valorized by chemical treatment and tested for its ability to remove cationic dye from aqueous solution. tendu (diospyros melanoxylon) leaves refuse, a solid waste from bidi industry which caused disposal problem, was studied as a biosorbent. raw tendu waste (tlr), along with sulfuric acid carbonized tendu waste (tlr-cm) and tendu waste treated with dilute...

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(3): 847–854. In the present article is shown the use of Maple program for processing of data describing the position of municipal waste sources and topology of collecting area. The data ...

Introduction: About 50 to 70 percent of the waste management total cost is spent on collection operations, so any little progress in reducing collection costs could significantly reduce total costs. This study aimed to analyze the collection and transportation of municipal solid waste cost in Yazd in the next 15 years. Materials and Methods: The study location (five areas) was different urban ...

Waste transfer-stations play an important role in a community’s waste management system, serving as the link between a community’s solid waste collection program and a final waste disposal facility. This study aims to estimate economic values of externalities related to waste transfer-stations in Israel. Most externalities are associated with local disamenities experienced by residents living i...

The facility layout problem is one of the fundamental production system management problems. It has a significant impact on overall efficiency. This paper introduces new that allows for choosing from multiple variants each facility. need most suitable selection while at same time optimizing other quality indicators represents optimization challenge. We build our previous work where single- and ...
