COMPOST QUALITY

The EarthCare Technologies, Inc. compost process of bioremediated, active, thermophilic windrow composting, maintains a pH of 6-8 throughout the eight to thirteen (8-13) week process. This is a critical factor as it relates to heavy metal leaching in mixed M.S.W. compost production. The EarthTender compost windrow turner is supplied by ECTI, as part of the facility co-composting equipment. This machine was specifically designed to fully aerate the composting material and provide the proprietary inocula the optimum conditions needed to biodegrade the organic fractions. Other processes utilizing a compost windrow turner rely only on the major physical degradation of the solid waste. This occurs due to the "cutting/chopping" type tines rotating at 1000 or higher RPMs. If particle size alone is the criteria for good compost, then mechanical degradation such as grinding, flailing or tumbling should be adequate. In EarthCare's process the final products particle size is attained solely by the biological decomposition of the organic materials.

The extremely large windrows used in other processes, lack the ability to control the microbial conditions necessary for good compost production. The in vessel systems rely mainly on high temperatures and physical breakdown in a rotating tumbler. They then utilize several weeks of "curing" to finish the compost. In essence, "curing" is nothing more than a loss of biological control. The reliance upon high temperatures will destroy as many of the good microbes as it does the pathogens. Again in comparison, EarthCare's process uses lower temperatures to insure the proper synergistic relationship between organisms. These organisms produce their enzymes in the 50-120 degree Fahrenheit range. Pathogens are controlled biologically also by mixing select microbes in the inocula that are antagonistic to these pathogens.

Odor control is accomplished through the same manner; selected organisms target and breakdown the ammonia, sulfides and mercaptans present in the composting materials.

Most compost processes utilize only those organisms prevalent in the waste materials. These are known as indigenous organisms and are not the most effective. In a composting row inoculated with EarthCare's inocula, there exists a multi tiered competition of different organisms. This mix assures that the proper microorganisms are present to biodegrade the organic compounds, control odors and pathogens and work in harmony to produce the highest quality compost available.

EarthCare's process composts all forms of organic materials, solids, liquids and sludge's. ECTI's fully stabilized finished compost product exceeds all established State and Federal compost regulations available today. Organic contaminants which are considered toxic or hazardous and not currently under regulation may be present in others compost product. Through years of product testing of ECTI's finished compost, it has been found that these compounds are fully degraded and not present in ECTI's final product.

By reviewing the laboratory analysis of the compost produced under the controls of the ECTI process (available upon request) shows that the finished compost product exceeds all State and Federal regulatory parameters for a Class A, unrestricted use product regardless of the initial feed stocks. EarthCare has consistently produced a Class A compost utilizing mixed municipal solid waste, sludges, septage, landfill leachate, non-hazardous liquids (restaurant grease trap, automotive repair shop sump pit wastes, etc.) construction debris, including treated lumber, creosote debris, and all animal waste by products.

More important than pleasing the eye and nose of the product user, a clean safe and fully stabilized compost product is generated in the EarthCare process. As an added bonus the compost product contains select microbes, one which has as its sole function to fix free nitrogen from the air to the root zone of the plants on a year round basis. A wide range of chelated micro nutrients are available for plant nutrition and simple sugars are present to promote further growth of good microbes in the soil. Also contained within the finished compost product produced by EarthCare are select microbes that inhibit soil borne funguses and nematodes which destroy the root systems of plants.
