WARNING! Sewage sludge is toxic. Food should not be grown in "biosolids." Join the Food Rights Network.

The Mulch and Soil Council (MSC) is a trade association "for all producers of horticultural mulches, consumer potting soils and commercial growing media," according to its website.[1] The MSC is based in Manassas, Virginia. The Council was formerly the National Bark and Soil Producers Association. Kellogg Garden Products is a member,[2] and sewage sludge-based products such as Amend carry the Mulch and Soil Council seal.[3]

The MSC promotes the industries of commercially prepared composts and mulches; thus, these mulches, potting soils and growing media may contain sewage sludge from municipal or regional wastewater treatment plants disguised as "biosolids compost." Several members of the MSC's Board of Directors work for companies that promote the spreading of sewage sludge on food-growing lands, including Rick Mahoney of Garick, an environmental consulting company based in Cleveland, Ohio, that promotes "biosolids." Other board members also work for biosolids-promoting companies like SunGro Horticulture.

Mulch and Soil Council "Certification" and Heavy Metals Testing

The MSC promotes mulch and soil amendment manufacturers to participate in the Council's certification process, which combines lab analysis with greenhouse growth testing, the results of which prompt the MSC to form certain "acceptable levels" guidelines for metals, pH and salt solubility in mulches and other growing media.

However, the MSC allows for up to 10 ppm chromated copper arsenate, a compound of copper, chromium and arsenic that often appears in mulches due to treated wood--wood used in construction and resulting from demolition--being ground up into mulches. The MSC also does not test for other heavy metals that may be present in sewage sludge compost.[4]

Sewage sludge contains a host of contaminants, including pathogens, antibiotics, heavy metals like cadmium, silver, lead and mercury. Food should never be grown in toxic sludge.
