Recently in Thailand, the recycling process of waste printed circuit board (WPCB) has retained a large volume of nonmetallic fraction (NMF), which has entered the industrial waste stream and awaits an appropriate treatment to be suggested. The aim of this paper was to assess environmental impacts of the recycled nonmetallic fraction from waste printed circuit board in Thailand, using the ReCiPe...

The disposal of polymer solid waste by means other than landfilling is necessary. The various approaches-source reduction, incineration, degradation, composting, and recycling-all have their roles and must be employed in an integrated manner. Where appropriate, recycling has ecological advantages, but its application is dependent upon the feasibility of collection, sorting, and/or compatibiliza...

The Gram-negative bacterium Klebsiella planticola represents an interesting host organism for the production of biotechnological products. Microbial processes – especially those of aerobic cultivation – lead to the generation of considerable amounts of biomass, thus lowering the product yield. These are the reasons for studying methods for the recycling of biomass from K. planticola. It will be...

Machining operations of cast parts usually generate considerable amounts of waste in the form of chips (usually 3–5% of the casting weight). Traditionally, swarf is sold to scrapers and remelters, but this option is quite expensive because the selling price is roughly 30% of the acquisition price of the commercial 2nd melt raw material. For most aluminium foundries that incorporate machining op...

Previous studies on hydroformylation of methyl oleate with rhodium and triphenylphosphine or triphenylphosphite have led to a laboratory process for recycling the precious metal catalyst. Another catalyst recycling process has now been studied as the basis for converting commercially available oleic acid into the enol ether of methyl formylstearate. The process involves one-step esterification-...

Patients with Charcot-Marie-Tooth neuropathy and gene targeting in mice revealed an essential role for the SH3TC2 gene in peripheral nerve myelination. SH3TC2 expression is restricted to Schwann cells in the peripheral nervous system, and the gene product, SH3TC2, localizes to the perinuclear recycling compartment. Here, we show that SH3TC2 interacts with the small guanosine triphosphatase Rab1...

this paper investigates householders’ attitudes to the recycling of solid wastes in one part of northern malaysia, namely alor setar town, kedah state. a postal questionnaire survey was administered to households in alor setar town in selected areas of high, middle and low incomes. 389 responses were obtained, a response rate of 86.4%. a personal interview with an official of the municipal co...

recycling process is one of the most important processes in the trend of sustainable development,a logical reaction against the problems that results from industrial age. building materials can play an important rolein the process of a building formation or destruction, in fact, materials forms the building nature. thus, the role ofmaterial and the impact of its recycling in sustainable develop...

Contaminants cause a decrease in the quality of materials with each recycling step. These quality losses should be minimized to increase the sustainability of resources use. Quality losses cannot be measured using weight-based recovery definitions alone, as the quality degradation cannot be translated by mass measures. Therefore, a better measure of the efficiency of resource use is investigate...

This paper develops a new performance evaluation approach for evaluating the relative recycling sustainability performance of e-waste products in terms of their contribution to the corporate sustainability of an e-recycling company. A fuzzy pairwise comparison process is used to help make comparative assessments. A fuzzy technique for order preference by similarity to ideal solution (TOPSIS) is...
