CARE Grantee Case Study: Sierra Mat & Rubber

Posted on November 10, 2017


Sierra Mat & Rubber received a CARE grant to begin manufacturing products comprised of post-consumer carpet backing and other recycled materials at its existing Northern California facility. Carpet backing in the form of a calcium carbonate sand is mixed with recycled rubber to manufacture commercial floor mats, landscape pavers, wheel stops and other products. Grant-funded equipment included presses, molds and a calcium carbonate bagger to transport the carpet backing material from the manufacturing facility to various California job sites. Sierra Mat & Rubber also became the first manufacturer of Double GreenTM products, which incorporate post-consumer carpet and one other recycled material.


TIMELINE: April 2016-December 2017

✔ Recycled-content products are new to the market.

✔ Products are still undergoing testing and development.

✔ The largest challenge is the sieve size of the calcium carbonate. The material is fine and dusty. Sierra has changed its existing material handling systems to deal with the dust factor.

✔ Securing continued support for testing and market development.


✔ CARE technical assistance.

✔ CARE facilitates business relationships for product line expansion and development.

✔ CARE develops Double GreenTM certification to assist in marketing plan.

✔ A CARE grant has allowed Sierra to lower its raw material cost in order to be more cost-competitive. The equipment has allowed Sierra the ability to produce larger mats, which require more PCC material and enable Sierra to enter commercial markets.
