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.

Resource recoveryWikipedia

Our team stepped onto the solid waste scene in the 1970s with our work for the City of Lincoln and Metro Waste in Des Moines. We quickly became known as a go-to firm for all forms of solid waste consulting by the 1980s. Today we can proudly say that our team’s talents have helped our clients’ solid waste facilities receive more than 25 awards for excellence in design.

Computer circuit board scrap was first treated with one part concentrated nitric acid and two parts water at 70°C for 1 h. This step dissolved the base metals, thereby liberating the chips from the boards. After solid—liquid separation, the chips, intermixed with some metallic flakes and tin oxide precipitate, were mechanically crushed to liberate the base and precious metals contained .
