What is Dynamic Composting ™ ?

Dynamic composting is an accelerated composting technique which turns organic waste into a humus like material called compost. The reaction of dynamic composting takes only three days to achieve compared with up to ninety days in other composting techniques.

Why is Dynamic Composting ™ so Quick ?

An enzymatic and bacterial preparation mixed with the organic waste accelerates the fermentation process of the waste, hence accelerating their degradation into compost.

Where does Dynamic Composting ™ Take Place ?

The dynamic composting reaction takes place inside a Rotary Drum Composter™. It is a steel drum especially manufactured to accommodate 5 tons of Municipal Solid Waste DAILY. The drum provides the ideal environment for the enzymatic/bacterial preparation to act on the organic part of the municipal solid waste.

What happens to the inorganic part of the Municipal Solid Waste?

Inorganics in the waste stream are unaffected by the Dynamic Composting ™ reaction. These are plastics, aluminum, metals, textiles, rubber, etc… These materials are separated from the compost generated at the end of the 3 day cycle of Dynamic Composting™.

How Environmentally safe is the Dynamic Composting ™ Technique?

Cedar Environmental is following US Environmental Protection Agency Standards for compost application on land as outlined in the Code of Federal Regulations for the Environment under EPA503. To determine the safety of compost applied to land the EPA concerns itself with two vectors which might cause pollution: 1- Pathogens: (EPA503.32/33) Salmonella sp. Shall be less than 3 Most Probable Number per 4 grs. of dry solids. eight samples drawn over a period of two years were analyzed for levels of Salmonella and all eight samples proved to have zero levels of Salmonella.
2- Heavy Metals: (EPA503.13 table 1) Regulatory Maximums for Class 1 Compost Parts Per Million, Dry Weight -

  Cadmium Selenium Copper Lead Mercury Nickel Arsenic
<0.3 3.5 110 50 <0.05 50 1.3
EPA503 85 100 4300 840 57 420 75

The compost generated using the Dynamic Composting technique qualifies as "Exceptional Quality" under the EPA Federal regulations. This designation, called the "EQS" designation in the Federal 503 regulations, allows unrestricted use of the Cedar Environmental compost in agriculture and for use on lawns and gardens.

How about odors from the process ?

By containing the material within a drum, the ideal environment for microbial activity is maintained. Odor is eliminated by the containment and by the rapid degradation. The three basic ingredients for creating the ideal environment for microbial degradation are nitrogen, oxygen and moisture. It requires a container, or drum, to create and control the ideal environment with these components. Without control of the chemistry, odor occurs. Although composting rules call for odor control in the facility, this is no assurance that it will solve the problem. Many "properly equipped" plants can still have problems. By contrast, the containment in an Rotary Drum Composter™ and rapid degradation due to a controlled environment eliminate odor problems.
