Bioremediation of oily solids
Environmental Remedies (ERCO) a sister company of G-force Consulting Engineers
BV was establish in March 2000 for the purpose of completing the process of oily
waste treatment through decommissioning the solids waste removed from the liquid
waste treated in G-force Plants.
Regulations under USEPA
ERCO is unique in that it specializes only in the treatment of oily “solids”
waste utilizing the method of Compost Bioremediation. This method allows for the
decommissioning of oily solids through a natural process of hydrocarbon
decomposition by microbial action. The finished product, after the removal of
oil, is  a
commercial grade product if declassified under the USEPA 503 Rule. By meeting
this USEPA specification the compost material can be bagged and market through
the Agriculture and Ornamental Horticulture business sectors.
The process
Composting of oily solids requires approximately 4 months to reach
declassification. Oily waste solids having an oil content in the range of 5% to
50% are suitable for composting. This is similar to a farming operation where
rows are laid out and tended to throughout the oil decomposition period to
insure optimum microbial activity. This involves row building, the addition of
nutrients and most importantly periodic watering and the daily induction of
oxygen by custom designed equipment. Recording keeping is paramount to track all
incoming oily waste and outgoing treated compost to comply with audits and
regional environmental regulations. This also involves analytical and field
laboratory testing to benchmark initial and final oil content and trace element
measurements required for closure. ERCO provide the know-how, the specialized
equipment and/or the full services to operate
the Waste Facility handling all composting requirements at a fixed rate per m³.

Free pore space (FPS) =
100(1-BD/SG) x Dry Mass
BD = Bulk Density & SG = Specific Gravity
Maximum Oxygen consumption (equated to maximum microbial activity)
in a composting operation occur at approximately
65% moisture and a FPS of 30%
