Life cycle assessment (LCA) methodology was used to determine the optimum municipal solid waste (MSW) management strategy for Eskisehir city. Eskisehir is one of the developing cities of Turkey where a total of approximately 750tons/day of waste is generated. An effective MSW management system is needed in this city since the generated MSW is dumped in an unregulated dumping site that has no li...

a comprehensive and integrated study of any supply chain (sc) environment is a vital requirement that can create various advantages for the sc owners. this consideration causes productive managing of the sc through its whole wide components from upstream suppliers to downstream retailers and customers.  on this issue, despite many valuable studies reported in the current literature, considerabl...

The Pollution Prevention Program provides free technical assistance to North Carolina industries and municipalities on ways to reduce, recycle and prevent wastes before they become pollutants. This non-regulatory program, located in the Division of Environmental Management, addresses water and air quality, toxic materials, and solid and hazardous waste. Designated as the lead agency in waste re...

Inspired by a real-life case in the Brussels Capital Region, Belgium, this paper provides Memetic Algorithm with Sequential Split procedure (MASS) for solving large variety of waste collection problems multiple depots, restricted vehicle fleet at each depot, (intermediate) processing facilities, capacity restrictions per facility and partial pick-ups. MASS first generates satisfactory initial s...

experiments were set up to estimate the effectiveness of clinoptilolite for the removal ofarsenate from aqueous solutions. the removal of arsenate by the exchanged forms was analyzed in thelight of the langmuir model of adsorption. a kinetic study of adsorption was carried out at differentintervals of time, and the kad values were calculated by using lagergren’s equation. adsorption ofarsenate ...

The recent introduction of non-burn, health care risk waste treatment technologies, such as ETD TM autoclaving, microwaving and steam sterilisation into Gauteng Province, has required the development of both the standards and the monitoring procedures that will ensure that these treatment processes will provide an acceptable level of microbial inactivation and will continue to do so during the ...

1 This paper presents a study to evaluate the recently developed enzymatic 2 hydrolysis test (EHT) through its repeated application to a waste treatment process. A 3 single waste treatment facility, involving a biodrying process, has been monitored using 4 three different methods to assess the biodegradable content of the organic waste fractions. 5 These test methods were the anaerobic BMc, aer...

Introduction The vitrification of nuclear waste in joule-heated melters is a costly multi-decade national effort. Current operations at the Defense Waste Processing Facility (DWPF) and future operations at the Waste Treatment Plant (WTP), now under construction at Hanford, rely on predictive models because of the lack of on-line monitoring of most processing parameters. This necessitates conser...

Appropriate vehicle routing is critical for collecting municipal solid waste (MSW) efficiently. Conventional empirical routing is not easily altered in response to rapidly changing waste management plans and generation. An enhanced model is proposed herein to solve a MSW collection routing problem involving a homogenous fleet. A minimum cost flow method is applied to pre-process the original co...

in this paper, a location allocation (la) problem in construction and demolition (c&d;) waste management (wm) is studied. a bi-level model for this problem under a fuzzy random environment is presented where the upper level is the governments who sets up the processing centers, and the lower level are the administrators of different construction projects who control c&d; waste and the after tre...
