HAZARDOUS INDUSTRIAL WASTE TREATMENT - CHAPTER 5 DOC

CCA-treated timber is commonly a greenish color, but this is also often the case with theother copper-based preservatives. CCA-treated timber is registered for use by the industrialcountries under their laws. The registered uses include internal building uses and external usessuch as decks, walkways[r]

sludges; agriculturalwastes,such ascorn cobsand ma-nure; and mine tailings. However, municipal wastetakes priority as far as recycling goes; one reason isthat, if buried in landfills, some of these materials(paint, radioactive elements of smoke alarms, insecti-cide, nickel-cadmium batteries, and the[r]
