RATHWELL, MB--(Marketwired - May 31, 2013) - Hutech21Co. Ltd. ( PINKSHEETS : CLGZF ), d.b.a. Prairie Oil Field Services Ltd.("Prairie Oil Field" or "the Company"), a mining, manufacturer and distributor of crushed gravel and sand materials in North America, announced today that it plans to negotiate the licensing of a biotreatment process that can provide year round, quick, simple and efficient solution to dispose of contaminated soils. The technology is completely natural and does not represent a threat to human health, plants and animals. In fact, all the microorganisms used are included in the list of substances authorized by the Canadian Food Inspection Agency.

"What makes this process different from other biotechnologies is its superior effectiveness and ability to quickly attain results -- turning contaminated, wasted soil into revenue-generating, reusable soils," said Darcy Hird, President and CEO of Prairie Oil Field. "The demand for this type of technology across Canada is very significant. We can apply it to soils contaminated by petroleum, diesel and light petroleum hydrocarbons. As a result, we will offer a wide range of complementary services for an integrated management of contaminated soils."

Related services include the excavation, transportation and rehabilitation of contaminated sites. All the activities related to the environmental follow-up are under the responsibility of an independent firm with a renowned experience in the biotreatment of contaminated soils.
