“Trendsetting procedure”

The TÜV SÜD Industrie Service GmbH successfully audited the NHS+ procedure under laboratory conditions.

A laboratory test offered successful evidence of the decomposition of heating oil, raw oil and the solvent tetrachloroethylene (PERC) in various kinds of soil.Test soils were pure sand, a sand-clay mix and humous topsoil. The inspectors certified that the “novel and trendsetting procedure is suitable for the fast and very effective decomposition of hydrocarbons.”

The procedure, referred to as “super oxidation,” uses commercially available and naturally degradable chemicals such as diluted active substances of soda and peroxide to dissolve hydrocarbons (e.g., various oils) in contaminated soils. The only end products that result from the degradation of the hydrocarbons are water, oxygen and a natural carbonate. No CO2 is released in the process.

The responsible assessor at TÜV SÜD, geologist Hans Betko, commented positively on the degradation results: “The innovative NHS+ procedure heralds a paradigm change in the remediation of contaminated soil. We have achieved astoundingly good results with clay-poor soils with wettable components, such as sand or gravel. NHS+ is fast and enables the regeneration of the remediated soils. Overall it is an elegant and cost-effective solution.”

Arva CEO Bernd Sydow appeared very pleased about the attestation by the renowned testing company: “This is a milestone for us and confirms the long-term research and development work in an independent expert’s report.”
