Sustainability and Diatomaceous Earth Spent Cake

Posted by appliedm on May 11th, 2016 in blog |

We are actively helping our customers recycle our minerals. Many of our customers use our minerals, primarily diatomaceous earth (DE) for filtration – for wine, beer, juice, and other beverages. After filtering the product, the customer is left with a by-product called “spent cake.” We’ve worked diligently with many of our customers to identify local sustainable alternatives to recycling the spent cake instead of it ending up in a landfill.

EP Minerals’ Director of Sustainability Andrew Welford recently worked with Iowa agricultural experts to plan and implement a trial to recycle the diatomaceous earth spent cake from filtration into fertilizer-with significant results. The results from the trial were surprising, and paved the way for recycling spent cake into fertilizer as a standard for the Iowa agricultural industry. Potentially in this trial, 9000 tons of waste could be diverted from landfill.

Another example of recycling diatomaceous earth is at Sonoma Compost, a certified organic compost facility in Petaluma, CA. Sonoma Compost ran the Organic Recycling Program on behalf of the Sonoma County Waste Management Agency. Since 1993, Sonoma Compost has successfully diverted approximately 1,460,000 tons of yard trimmings and wood waste from landfills. Sonoma Compost turned those materials into organic compost and mulch, recycled lumber and biofuel, all which they sold at very affordable prices for agriculture, landscaping and gardening.
