Scientists at America’s Rice University have ‘fine-tuned’ a method to restore the fertility of soil that is contaminated by oil spills. Scientists heated contaminated soil samples in the absence of oxygen, a process named pyrolysis, and successfully reduced petroleum hydrocarbons to below regulatory mandates. Samples heated at 420°C for 15 minutes reduced 99.9% hydrocarbons
