phenomenon of used material and salvage yards will have metamorphose into full-blown eco-building centres with a range of functions and services. They would sell used and reconditioned building materials, and even new products would be increasingly remanufactured or containing large percentages of recycled materials. They would be depots for purchase as well as sale of used materials, likely connected to resource recovery parks and close to repair and remanufacturing facilities. Perhaps most importantly, this would make them centres for deconstruction servicesin the same way that some used building material retailers today already employ deconstruction teams. The transformation of building supply retailers into education centres is a natural expression of postindustrial developmentin which resources are replaced by information. This is particularly true in an economy where do-it-yourself activities are constantly growing as a portion of the economy. Lumber yards and building centres are logical places for workshops on materials, techniques and equipment. In fact, D-I-Y workshops are already a strong trend among retailers like Woodlands, Rona and Home Depot; what needs to be added is some environmental content. There are some obvious challenges in this kind of transition, though. Currently educational activities are designed as ways to increase material sales, and are subsidized by sales. By rights, information should substitute for material sales, and yet it seems undesirable to charge for information and education. Income for retailers should be connected to material savingsthrough remanufacturing, deconstruction, education, ecolabelling and community indicator projects. Green taxes would be one way of discouraging maximum sales of products, especially if tax revenues were earmarked for conservation education.
