The Aerated Static Pile (ASP) is the simplest and least cost approach to composting large volumes of organic waste materials.  The ASP System is ideally suited for facilities that manage large           volumes of livestock manure, yard debris, food scrap waste and other challenging feedstock             materials.


Most people believe that compost needs to be turned to maintain aerobic conditions. However, when air is introduced into an active compost pile by turning, the oxygen level in the pile drops off very quickly, often to less than 1% oxygen content within 30 to 45 minutes.
For this reason, “turning the pile” is an expensive and ineffective.


O2Compost has developed a wide array of aerated compost systems for every scale of operation; for every organic by-product; and for every budget.  We believe that composting is vital to establishing a sustainable world community.  As environmental engineers, scientists and educators, O2Compost’s mission is to provide the Science and Art of Aerated Composting and to empower individuals and organizations to become stewards of their land, air and water resources.


INSTITUTIONAL COMPOSTING - Institutional compost systems are like municipal compost systems in terms of the organic feedstocks that they process. These materials include landscape debris, food scrap waste, animal manure, wastepaper products, and biosolids. Institutions that can take full advantage of on-campus composting include colleges and universities, corporate campuses, hospitals, prisons, military bases, retreats, and summer camps.

MUNICIPAL COMPOSTING - Municipal compost systems generally manage the full spectrum of organic wastes collected from local communities. These wastes include landscape debris, pre- and post-consumer food scrap waste, animal manure, roadkill, and biosolids.

COMMERCIAL COMPOSTING - Commercial compost systems generally manage a narrow range of feedstock materials in relatively large volumes. Fish waste, grape pumace, fruit pulp, greenhouse residuals, and some agricultural / livestock by-products such as beef paunch manure and poultry offal.

AQUACULTURE COMPOSTING - There are many fish farms, hatcheries, and fish processing plants in Canada. Add fish waste to a compost mix pile with temperatures exceeding 131 degrees F. and within 3-days there is no evidence of fish remains. There is no “fishy” odor and will not attract pets or wildlife. It is nutrient-rich and full of beneficial microorganisms.

VERMICOMPOSTING - Whether you plan on selling your finished compost, vermicomposting will greatly enhance its quality by allowing the worms to perform their magic in your stockpile.                                                                     

AGRICULTURAL COMPOSTING - The volume of organic by-products derived from agriculture is enormous. Manure and animal mortalities are a reality for every farm that raises dairy cows, beef cattle, chickens, turkeys, and pigs. The same is true for "recreational" livestock such as horses, alpacas, and llamas. Considering the number of livestock being raised in the world today, the potential for adverse impacts to our land, air and water resources is incalculable.


Mitigates impacts to surface and ground water resources.

Produces high quality compost in 30 - 60 day.

Eliminates pathogens, parasites, and weed seeds.

No odors, no impact to air quality, reduced volatile organic compounds and greenhouse gases.

No Vectors like rodents, flies, and birds.

No pile turning. Greatly reduced cost of labor, fuel, and equipment use / maintenance.
