FAQ

Is EKO Compost safe to use on edible crops?


Yes, EKO Compost is classified by the US Environmental Protection Agency (EPA) as Class A compost, which is approved for unrestricted use.

Does EKO use human waste to make their compost?


Yes, EKO uses biosolids mixed with greenwaste to make their compost. Biosolids are nutrient-rich and contain essential plant nutrients, such as nitrogen and phosphorus, and organic matter.

Before reaching the EKO composting plants, the biosolids have already been treated and processed by the wastewater treatment facility. Once the biosolids are received at the EKO plant, the biosolids are immediately mixed with shredded greenwaste (mulch) and composted for an additional 160 to 180 days.

What is the difference between biosolids and sludge?


The term "sludge" describes the untreated solids removed in the domestic water treatment process. Sewage sludge is treated to kill pathogens and stabilize orgnaic matter to reduce odors and its appeal to insects and rodents. The treated product is called biosolids once it meets federal and state standards allowing it to be beneficially used for land application.

How do I know your compost is safe if you use biosolids?


The US Environmental Protection Agency (EPA) encourages biosolids recycling, but has strict guidelines that biosolids processors must follow. States may also have additional regulations that must be followed. EKO meets and exceeds all regulatory requirements. EKO also voluntarily participates in the US Composting Council's (USCC) Seal of Testing Assurance (STA) Program, which sets compost industry standards.

EKO follows a very thorough and monitored composting process. Prior to sale, EKO sends samples of compost to the lab to be tested for e.coli, salmonella, fecal coliform, and heavy metals. EKO also tests for various nutrient contents important for stable soil and healthy plant growth. These test results are available for public review upon request.

What about all the pharmaceuticals that humans ingest getting into the compost?


Pharmaceuticals are water soluble. They run out in the effluent (runoff) of the biosolids at the wastewater treatment facility when dewatered.

EKO conducted a test at our Missoula, Montana facility. The test results found that it would take 2 million gallons of effluent to equal one dose.
