The ultimate fate of products is an important issue in conducting environmental life cycle assessments, setting public policy on product disposal and tracing materials flows over time. This case study illustrates a methodology for estimating the fate of such products, focusing on personal computers. The methodology can be applied to a wide range of consumer products. Discarded or obsolete perso...

Improved recycling of end-of-life vehicles (ELVs) may serve as an important strategy to address resource security risks related to increased global demand for scarce metals. However, in-depth knowledge of the magnitude and fate of such metals entering ELV recycling is lacking. This paper quantifies input of 25 scarce metals to Swedish ELV recycling, and estimates the extent to which they are re...

With the booming of automobiles industry, recycling automobile shredder residue (ASR) with complicated constitutes gradually become an urgent issues owing to its difficulty for traditional recycling. Herein, solid-state shear milling (S3M) technology which can control domain size various polymers in blend was applied overcome mismatch viscosity and poor compatibility ASR thus modify processabil...

Paper and board are widely used as food packaging materials, mainly for disposable products. As public interest in conservation of natural resources has accelerated in the past several years, the use of recycled paper and board has increased. Recycled fiber materials can be used in certain limits as food contact materials. The safety of recycled fiber-based materials for food contact applicatio...

Recycling steel building components is key to the sustainability of a structure’s end-of-life, as it is the most economical solution. In this paper the effects of usage of recycled steel material in tall buildings aspects are investigated. Keywords—Building, recycled material, steel, structure.

this study describes the synthesis of molecularly imprinted polymers (mips) by using an anti-che ops, namely dursban, as a template. non-covalent bulk polymerization was successfully applied to synthesis different imprinted and non-imprinted polymers with maa, mma, aa, and 4-vpy as monomer in selected porogens (chloroform, toluene, and acetonitrile). in order to evaluate the template binding of...

ISSN 2277-5056 | © 2012 Bonfring Abstract--The use of recycled concrete aggregate is an important issue for preserving the natural resources, protecting the environment, saving of energy and for sustainable development. In this study, a unique simple mixture proportioning method was successfully adopted for developing SCC based on the absolute volume concept, starting with a volume of paste wit...

Selective flocculation has long been suggested as a method for the treatment of ultra-fine particles typical of which are those produced in a de-sliming process ahead of flotation. In this paper the results of the coal de-mineralization, using synthetic polyacrylamide polymers, are presented. A prescreening test on the suitability of the polymers using Run-Of-Mine (R.O.M.) coal and artificial m...

background: cattle can be considered as an important source for herbicides through nutrition. therefore, herbicide residue in animal products is a potential human exposure to herbicides causing public health problems in human life. triazines are a group of herbicides primarily used to control broadleaf weeds in corn and other feed ingredients and are considered as possible human carcinogens. to...
