Our recycled glass sand is made by our sister nonprofit Bottle Underground, a community-based recycling organization dedicated to reducing waste and finding better solutions for used glass.
We locally source used bottles from community members and businesses and divert it from the landfill. The sand is crushed to a mixed particle size that is ideal for soil. It can be mixed into the mulch, similar to horticultural sand, or placed decoratively on top. You can find more information on OLIN Lab's pilot study with our sand here!
