Remediation of Contaminated Soils using Sustainable Soil AmendmentsReagents

Treatment of surficial soils contaminated with TPH, PAHs, chlorophenols etc. has traditionally adopted the use of commercial and agricultural fertilizers. This approach often fails because the commercial and agricultural fertilizers are unable to create the right conditions for the indigenous microorganisms to survive and thrive. The traditional approach fails to address the issue of acute microbial toxicity, bioavailable water and the optimal ratio and release of organic carbon, nitrogen and phosphorus to facilitate contamination degradation. This presentation will discuss the use of sustainable reagents derived from plant fibers that are designed to overcome the limitations of the traditional approach thereby providing an efficient, cost-effective and a sustainable remediation option.
