Puerto Rico grinds through hurricane debris

Article Abstract:

The Puerto Rico Solid Waste Management Agency, the Dept of Natural Resources and Dept of Transportation (DOT) were tasked to clean up the debris and damage caused by Hurricane George which devastated Puerto Rico on Sep 21, 1998. The hurricane caused widespread damage to trees, shrubs and wooden structures so that most of the debris were composed of woody material. The Luis Munoz Marin Park in the city of San Juan was chosen to be the collection and processing site for the debris. After the storm, the DOT collected 300 truckloads of debris daily for one week, and 500 truckloads daily for another week.

Milling option for urban trees

Article Abstract:

The high cost of tree disposal led the city of Hammond, Indiana to put in place a Trees to Furniture project. The trees were processed into lumber by Hoosier Sawmill, which kept 70% of the lumber, while the city used the other 30% to repair park benches, picnic tables and ballards. After Hoosier Sawmill went out of business, the Lake County Solid Waste Management District (LCSWMD) sought a grant to continue the program and purchase a portable sawmill from Wood-Mizer. Hammond also plans to purchase a kiln so that the wood can be dried and products made of lumber from the Trees to Furniture program.

Recycled wood and plastic composites find markets

Article Abstract:

The use of wood and plastic composites helps in producing strong, stable, well insulated and weather resistant finished products. The addition of wood fibers to plastic materials reduces production costs, production time and weight of the finished product. Management of the wood feedstock moisture content, melting temperature and the feeding of the wood filler into the manufacturing process are some of the problems involved in the process. Organizations, such as Natural Fiber Composites and Andersen Corporation, are using plastic and wood composites for manufacturing the final products.
