Rubber Mulch

Rubber mulch is a type of mulch used in gardens and sustainable landscaping that is made from recycled rubber. Rubber mulch generally consists of either waste tire buffings or nuggets of synthetic rubber from tires that are ground up a whole, after having their steel bands removed. Almost any tire can be used to make rubber mulch, including passenger vehicle tires and large truck and trailer tires. Buffings are produced from recycled truck tire tread when the remainder of the worn-down tread is removed from the tire prior to retreading. Buffings are generally thin slivers of rubber. Nuggets range in size from 10 mm to 32 mm, or 3/8 inch to 1​1⁄4 inch.
