Composted Biosolids - What's the Story

Viragrow does not hide the fact we have have and use a compost made from municipal solid waste (MSW). This is our famous Viragrow Compost, sometimes just called "166". 

MSW contains biosolids. They all do. The most famous one that comes to mind is Milorganite made from MSW originating in Milwaukee since 1926.

Recycling

That is what we call it. Recycling is not for everyone but we feel we created  our own waste so finding a use for it is the responsible thing to do. The question becomes, how should it be used? Lawns and turfgrass only? Amending the soil for ornamental trees and shrubs? Vegetable gardens and fruit trees? 

About 24 years ago, when composting technology was not as sophisticated, the only option was to use it on nonedible landscaping. That all changed with protocol published in the Federal Register in 1993 and the development of federal standards for Class A and Class B compost.

EPA and 40 CFR 503

The EPA (Environmental Protection Agency) was given the task to step in and create a pathway of federally regulated composting so this valuable resource (yes, MSW and biosolids)  was put to better use. They were given the task of regulating it so it is as safe as possible. This was the beginning of the 40 CFR 503. 

The "legal eagles" official version can be found hosted by the Cornell Law School. For us not versed in these legal foundations, we can read the "plain english" version here.

Birth of "Organic" Compost

Four years ago Viragrow only carried compost made from MSW.  That was Viragrow's "bread and butter". But everyone wanted an "organic" compost. What "organic" meant to our customers varied from no MSW to "pesticide free". 

Thus Viragrows "organic" or "vegan" compost was borne in 2017. It told our customers that there were no pesticides present and the compost was made from plant products. 

(Quotes around the term "organic" separates it from the standardized USDA Organic Program or NOP.)

Viragrow Compost

Viragrow believes you should have choices; support the recycling movement and use municipal waste compost (Viragrow Compost, aka 166) or elect to use a product that contains no biosolids ("organic" or "vegan" compost). Viragrow listened to its customers. Four years ago, "organic" compost was made waste coming from lumber mills in California and Oregon specifically for Viragrow's customer base in Las Vegas.
