This modular shelving system from Build is a durable alternative to the generic shelving systems that often last just a few years before ending up in a landfill. Because Build is made entirely from polypropylene with no glue or metal, it is completely recyclable and can be placed in a curbside recycling bin at the end of its useful life. Currently in the preorder phase while the company is crowd-funding its official launch, Build comes with a closed or opened back and in black or white.
