Sustainability Norwood’s PP5 is a polypropylene compound that is non-toxic and 100% recyclable. Customers can return their unused tags and other poly materials to Norwood for processing by our recycling partner, Martogg LCM. By re-using this material, which would otherwise go to landfill, we’re able to reduce our energy output. Combined with our own production off-cuts we shred, pellet and reform the waste into new products, which include car parts and building materials.
