Remediation of soil contaminated by oil, chemicals, acid tars & mercury.

Uni-Recycling carries out all necessary steps for site rehabilitation. Soil remediation is a complex process which requires careful attention in investigation, expertise in identification of the optimal method and correct application of the mechanical, physiochemical, thermal or biological remediation procedures.

Remediation can be conducted IN-SITE, on-site or off-site, with the technology tailored to the specific contamination type, local regulations and various factors to achieve optimal outcomes.

Applied Methods

Stabilization/Solidification

This method involves treating contaminated soil or waste by adding materials to chemically bind contaminants and prevent their migration, creating a stable, solid material that is less harmful. It is applied by mixing additives with the contaminated material to reduce the mobility of contaminants.

Bioremediation

Bioremediation uses living organisms such as bacteria, fungi, or plants to degrade or metabolize contaminants into less harmful substances. This method can be applied by introducing these organisms to the contaminated site and creating conditions favorable for their growth and activity.

Soil Washing

Soil washing is a physical separation technique that uses water or solvents to remove contaminants from soil particles. It involves washing the contaminated soil with a washing solution and separating the clean soil from the wash solution and contaminants. This method can be applied on-site using specialized equipment.

Ecological Restoration

Ecological restoration aims to recreate or rehabilitate a natural habitat that has been impacted by contamination, restoring its ecological functions and biodiversity. This method involves a holistic approach that may include planting native vegetation, reintroducing wildlife, and creating conditions for ecosystem recovery, often requiring long-term monitoring and maintenance.

Contaminated soil poses a significant threat to ecosystems, with potential impacts on both human health and the natural environment. Soil remediation plays a crucial role in mitigating these risks by safeguarding underground water resources, restoring the natural landscape and facilitating the safe repurposing of land for various new applications. By effectively addressing soil contamination, we not only protect the environment but also ensure the well-being of present and future generations.
