Solvent extraction of CCA-C from out-of-service wood
1998 - IRG/WP 98-50107
Elimination of CCA from decommissioned wood prior to disposal is a major environmental issue. One approach is to extract CCA from treated wood, then reuse the 'clean' (may contain CCA, but below hazardous level) wood materials for manufacturing wood-based composites. In the present paper, we focus on effective leaching processes, selection of leaching agents and optimum leaching ...

Treatment and recycle of CCA hazardous waste
1993 - IRG/WP 93-50007
Chromated copper arsenate containing hazardous materials is generated from the manufacture, treatment of the wood, and from the wood itself, after its life cycle. Laboratory treating of these wastes has resulted in materials suitable for recycle or disposal as non-hazardous residues. The extraction, by both acidic and ammoniacal routes, of CCA production and treating plant waste materials has been...

Characteristics of treated oriented strand lumber using recycle chips
2006 - IRG/WP 06-40343
The Kyoto Protocol for preventing global warming has come into effect, and the Cabinet Council was decided on the amount of carbon dioxide exhaust to be reduced in Japan. Moreover, the recycling of demolition waste wood is mandated under the “Construction Material Recycling Law” as one of the mechanisms for Japan to form the recycling society. The law encourages the utilization of demolition w...

Factors affecting sodium hypochlorite extraction of CCA preservative components from out of service treated wood for recycling
2009 - IRG/WP 09-50263
Significant amounts of chromated copper arsenate (CCA) treated wood products such as utility poles and residential constructions remain in service. There is an increasing public concern about environmental contamination from CCA treated wood when it is removed from service for reuse or recycling, placed in landfills or burned in commercial incinerators. In this paper, we investigate the effects of...
