Resource recoveryWikipedia

The aim is to reduce the amount of waste generated, therefore reducing the need for landfill space and also extracting maximum value from waste. Resource recovery delays the need to use raw materials in the manufacturing process. Materials found in municipal solid waste can be used to make new products.

Recovery of metal values from waste printed circuit boards

Of particular interests are the re-utilization and recovery of printed circuit boards (PCBs) which are the essential parts of electronic devices and constitute around 3 wt.% of WEEE (Marques et al., 2013). Unlike normal municipal solid wastes, waste PCBs may lead to tragic health, safety and environmental issues.

waste generated, but also because of the heavy metals and toxic substances it contains. This study analyzed printed circuit boards (PCBs) from discarded computers to determine their metal content and characterized them as solid waste and fuel. The analysis showed that PCBs consist of approximately 26% metal, made up mainly of copper, lead .

Recovery of Cu and Zn from waste printed circuit boards

In the complete process, the total recovery values of Pb and Sn were 94.54% and 97.67%, respectively. The blister Cu and residues had high economic rates, and further recovery can take place through electrolysis and hydrometallurgy. The proposed process enables the clean separation and recovery of various metals and alloys from WPCBs.

The proper disposal of electrical and electronic waste is currently a concern of researchers and environmental managers not only because of the large volume of such waste generated, but also because of the heavy metals and toxic substances it contains. This study analyzed printed circuit boards (PCBs) from discarded computers to determine their metal content and characterized them as solid .

Modelling separation strategies of municipal solid waste

The first Finnish National Waste Plan follows the waste policy of the European Union by setting high recovery rate targets, i.e., 50%wt by the end of 2000 and 70%wt by 2005, for municipal solid waste management (MSWM). A computer model, TASAR (Tool for Analysing Separation Actions and Recovery), was developed to study recovery levels reached by different separation strategies in …
