the recycling movement of the seventies. It is seen as a source of new skills, of environmental and building preservation, and of jobs and community economic development. According to Neil Seldman and Mark Jackson (2000, p.34) of the Institute for Local Self-Reliance (ILSR), If deconstruction were fully integrated into the U.S. demolition industry, which takes down about 200,000 buildings annually, the equivalent of 200,000 jobs would be created and $1 billion worth of building materials would be returned to the economy, with accompanying reductions in virgin material extraction. The challenges to the new movement are great however. Besides the fact that neither buildings or components have been designed for disassembly, tools for deconstruction are lacking; disposal costs are still too low; markets for recycled materials are often scarce or depressed; retail networks of reused building material centres are undeveloped; many materials are hazardous or unhealthy; deconstruction takes additional time and new skill-sets; recertification of reused components is often impossible; building codes tend not to support reuse of building components; accessible public information about reused/recycled building materials is limited; general awareness of the benefits and opportunities is low.
