Thanks to PATH-funded technology, a public park in Wisconsin has a 2,000 square foot service center for campers that features a panelized roofing system made from a composite of recycled milk jugs, waste sawdust, and other natural fibers. This roof will help demonstrate the potential of using waste wood, fiber, and plastic destined for the landfill in a value-added building product. The USDA Forest Products Laboratory (Madison, Wisconsin) and Teel-Global Resource Technologies (T-GRT) (Baraboo, Wisconsin) developed this new roofing system.
A panelized roofing system is an ideal application for this recycled composite because (1) the panels can be easily molded to match traditional roofing profiles, such as cedar shakes, Spanish tiles, or slate, and (2) the aesthetic nature of the panelized system provides an opportunity to showcase recycled material in a product that looks expensive but costs much less than the traditional product it replaces.
Compared with existing manufactured roofing systems, initial evaluation of this composite roofing system indicates several advantages:
T-GRT manufactured the roofing system materials used on the campground service center, and controlled weather-exposure testing for this application is being performed at the Forest Products Laboratory. Durability monitoring of the campground service center roof will be conducted for 2 years. The information collected will be used to further quantify labor and cost savings, ease of construction, and waste generated compared with conventional materials.
