The treatment of cooling appliances in Austria is mainly influenced by two factors. On the one hand is the changing composition of cooling appliances because of the CFC phase out, on the other hand are the minimum recycling rates stipulated by the ordinance on Waste Electrical and Electronic Equipment (WEEE ordinance). Two basic treatment practices can be identified in Austria: One type aiming ...

In this study, we propose that the ability to recycle may lead to increased resource usage compared to when a recycling option is not available. Supporting this hypothesis, our first experiment shows that consumers used more paper while evaluating a pair of scissors when the option to recycle was provided (vs. not provided). In a follow-up field experiment, we find that the per person restroom ...

A city's landfill is an exhaustible resource; recycling is a backstop method of waste disposal. We formulate an optimal control model that maximizes the total utility of a representative consumer by choosing the appropriate levels of the two disposal techniques. The model is simple enough that some general conclusions can be drawn, and yet specific solutions will require some computations that ...

In this paper, we focus on the difficulties of resource recycling problems relating to the used Iron and/or Aluminum cans. Based on the feedback control theory and combining with micro-chip processor, sensors, phonic chip, oil-compressor and mechanism technology, we design an interactive resource recycling Expert System –‘‘Recycling Squeezed Cans Device” (RSCD) and the proposed interactive RSCD...

processing and recovery is a key functional element in municipal solid waste management system (mswms). reuse, recycle and recovery of valuable components of waste stream are given much attention in mswms in both developed and developing countries. the main concern of municipalities is the sound management of recyclable materials. source separation as a best practice for management of trash and...

In this work, the waste stone sludge obtained from the granite and marble stone processing factories was used for the manufacture of artificial stones using vibratory compaction in a vacuum environment. The results obtained showed that water absorption and density increased, and the flexure, compressive, and tensile strengths decreased with increase in the content of the waste stone sludge. The...

High consumption of electrical and electronic equipment (EEE) is accompanied with a high yield of waste electrical and electronic equipment (WEEE). Meanwhile, because the different types of resources have their own unique properties, the current content of each type will remain limited in a range of fluctuations. Therefore, WEEE recycling is an obvious choice to meet the resource demands of the...
