Planting kenaf or eucalyptus to produce building products and other materials has also been discussed. These proposals go beyond design and construction issues to those of community and economic development. Construction materials including building insulation, structural fiberboard, laminat-ed paperboard, cement, concrete, polyester carpet, patio blocks, floor tiles, playground surfaces, running tracks, hydraulic mulch products, waste receptacles and office paper are listed with recommended levels of recovered material content. Hawaii Administrative Rules Subchapter 4, Chapter 3-124, Recycled Products, promotes the use of recycled products by state and county purchasing agencies. In accor-ance with Hawaii statutes there is a 10 percent price preference for recycled products in Department of Accounting and General Services projects.
Several publications are available on recycling and recycled materials.
The Clean Hawaii Center has published Recycled Products and Recycling Services in Hawaii. The State of Hawaii Procurement Office publication, Buy Recycled in Hawaii, describes the benefits of supporting recycling and recycled products. In addition, numerous databases, guides and World Wide Web sites list various environmentally-responsive building products and systems. The AlA Environmental Resource Guide and a bi-monthly publication, Environmental Bluilding News, are two excellent information sources for design professionals interested in environmentally responsible principles and products. Efforts to recycle reusable materials have extended throughout the community.
