Earth’s Choice biodegradable binders are made using an all natural organic additive. The polypropylene cover is formulated to biodegrade in microbial landfills within 5 years verses the hundreds of years it takes normal plastic. This binder is completely reusable with an unlimited shelf life and will not start to biodegrade until disposed of in a landfill. All contents are 100% recyclable. Archival and environmentally safe polypropylene will not lift copy. Overall binder contains over 47% post-consumer material and chipboard is made from 100% recycled material. This binder is designed with traditional round ring metals and two inside pockets. Customize the exterior of this binder with our clear overlay covers.
