WM EarthCare

Sustainable, locally sourced and produced, 100% recycled compost and mulch creating healthy gardens & a healthier planet

About WM EarthCareTM

The WM EarthCare family of products is a sustainable, closed-loop solution for Bay Area landscapers who want to reduce their carbon footprint while enriching local soil.  Our 100% recycled, locally sourced and produced compost and mulch closes the loop on Bay Area yard trimmings, food scraps and lumber debris, diverting them from landfills to restore our community.  Compost and mulch return nourishment and structure to local soil.  Our products are made with strict quality controls to ensure excellence and come with the backing of Waste Management, the nation’s leading resource recovery company.

Commitment to Sustainability

Choosing WM EarthCare for your landscaping needs fosters a healthier environment, local green jobs and long-term savings for you.  Replacing commercial fertilizers and herbicides with WM EarthCare compost and mulch reduces pollution run-off into local watersheds and decreases water usage through moisture retention.  In addition, use of our 100% recycled products may earn LEEDTM certification points.

We minimize the carbon emissions associated with production and distribution by relying on our existing trucking infrastructure to back-haul feedstock and finished product between our production facilities in Marin and Alameda counties and our retail landscape centers in Livermore, Novato, San Leandro, and  San Jose.

Quality Assurance

WM EarthCare Homegrown Compost follows a rigorous quality control process resulting in US Composting Council Seal of Testing Assurance (STA) and Organic Materials Review Institute (OMRI)-listing, the industry standards for excellence.  It is processed to be stable and mature, providing slow release nutrients that contribute to soil structure, moisture retention, aeration, drainage and tilth.

WM EarthCare mulch is made from 100% recycled, clean, untreated lumber.  It is hand inspected prior to being coarsely ground to 2” minus, screened and dyed.  The colorfast mulch, dyed with naturally occurring water-based colorants, is safe for children and animals and is guaranteed to retain its color for one year.  Custom sizing and colors are also available.

Community Involvement

Recover – Repurpose – Reuse – Restore – is how WM EarthCare is closing the loop on organic waste in Bay Area communities.  We are committed to building stronger communities and soil.  Through our donation program, we also Return compost and mulch to school and community gardens and urban beautification projects.  We work closely with our customers, including the California Academy of Sciences, CSU East Bay and more, to ensure on-time delivery, quality products and excellent service.
