A methodology has been developed to apply value chain analysis (VCA) to the informal recycling sector, and demonstrated using the Zabaleen in Cairo, Egypt as a case study. The VCA methodology provides a ⿿toolkit⿿ comprising four stages. The first involves ...
The paper analyzes the monetary value of precious and critical metals stocks in selected electronic equipment sold during 2004-2014 in Germany and at global level, as well as the value of the metals stock which is not being put to use. Initially a literatu ...
Siberian scientists showed by their scientific investigations that brines of Siberian Platform are a very important hydro mineral resource for economical development of the East Russia. Prospects for the integrated mining of the hydromineral resources in R ...
Sustainable recycling of e-waste bares opportunities as well as obstacles - mainly for small and medium size enterprises. Especially the current challenging market situation for second- hand raw materials makes it difficult for small e-waste recyclers to o ...
Phosphorus (P) is an essential, finite resource whose geological, economic, and geopolitical accessibility may become critical in the future. Because P losses from agriculture, sewage and waste have serious environmental impacts such as eutrophication, it ...
We consider a complex recyclable waste collection problem that extends the class of vehicle routing problems with intermediate facilities by integrating a heterogeneous fixed fleet and a flexible assignment of destination depots. Several additional side co ...
Construction and demolition (C&D) waste, being already the largest waste fraction in industrialized coun- tries, is expected to increase in the future. C&D waste recycling has been considered to be a valuable option not only for minimizing C&D waste stream ...
The quantities of e-waste are expected to increase sharply in Chile. The purpose of this paper is to provide a quantitative data basis on generated e-waste quantities. A material flow analysis was carried out assessing the generation of e-waste from comput ...
We consider a complex recyclable waste collection problem that extends the class of vehicle routing problems with intermediate facilities by integrating a heterogeneous fixed fleet and a flexible assignment of origin and destination depot. Several addition ...
A mobile sampling and measurement system for the analysis of gaseous and liquid samples in the field was developed. An inductively coupled plasma optical emission spectrometer (ICP-OES), which is built into a van, was used as detector. The analytical syste ...
