Test Results Are In for Porter County Compost

Porter County Recycling and Waste Reduction officials say the district’s compost continues to make the grade… according to test results from A&L Great Lakes Laboratories, the free compost available at the Valparaiso and Boone Grove sites meets the U.S. Composting Council’s Seal of Testing Assurance standards.   Compost producers are not required to have their compost tested, but the district says says meeting these standards identifies quality, so users know what they are getting and what they’re putting into their home gardens.

“Testing our product is a good way for us to validate our work,” said Therese Davis, executive director of Porter County Recycling & Waste Reduction. “The numbers are good. It meets the requirements for health, safety and maturity.”

In order to determine if the compost meets the standards of the U.S. Composting Council’s Seal of Testing Assurance, district officials say manufacturers are required to perform the C10 test that identifies and measures elements including solids, total nitrogen, phosphorus, potassium, calcium, magnesium, pH, soluble salts, organic matter, fecal coliform), germination, respiration and heavy metals.

A&L Great Lakes Laboratories, Inc. is approved by the U.S. Composting Council for conducting this test.

Compost from these sites is available for free to Porter County residents, while supplies last. Residents should bring their own shovels and containers to load as much compost as they want. For material availability, call 465-3694.

The Valparaiso site, 2150 W. Lincolnway, is owned and operated by the City of Valparaiso with assistance from Porter County Recycling & Waste Reduction. Regular season hours for the Valparaiso site are 9 a.m.to 5 p.m. Mondays through Fridays, and 9 a.m. to 4 p.m. Saturdays.

The city loads compost at the site for Porter County residents on Tuesdays, Thursdays and Saturdays for a fee. For more information, call the Valparaiso Public Works Department, 462-4612.

The Boone Grove compost site, 546 S. 400 W., is owned and operated Porter County Recycling & Waste Reduction.  Regular hours for the Boone Grove site are noon to 5 p.m. Mondays, Wednesdays and Fridays, and 9 a.m. to 4 p.m. Saturdays.

The district also sponsors the compost testing for three municipal sites that are not open to the public: Portage, Chesterton and the Pines. The results of the testing showed the compost from all three sites to be within normal parameters.

While the district partners with these municipalities to help manage their material, site logistics prevent public access, and the municipalities control the distribution of their product.

Test results from all five compost sites are available for public viewing on the district’s website, www.PorterCountyRecycling.org, or at the Porter County Recycling & Waste Reduction administration office, 155 Indiana Ave., Ste. 314, Valparaiso.
