Storage binder features a cover specially formulated to biodegrade in a microbial landfill in 1 to 5 years versus the hundreds of years it takes normal plastics. Removable rings make binder 100 percent recyclable. Chipboard is made from recycled material, and the acid-free polypropylene is environmentally safe. A portion of the proceeds from each binder purchased will be donated to American Forests to help plant a minimum of 7,500 trees annually. Binder features two inside pockets for extra storage of loose documents and traditional, metal round rings mounted to the back so the letter-size pages lie flat. 1-1/2 capacity holds approximately 350 sheets. Biodegradability test is made using ASTM D5511 standards.
