Bioremediation and Rehabilitation
environmental restoration
From Contamination to Recovery
Environmental incidents don’t end when the visible spill is removed. True recovery requires bioremediation and rehabilitation, addressing contamination at a chemical, biological, and ecological level. Drizit provides specialised bioremediation and environmental rehabilitation services that restore impacted land and water systems while meeting regulatory, environmental, and ESG obligations.
With more than 50 years of experience in pollution control and environmental services, Drizit is trusted to manage complex contamination challenges across South Africa and internationally, from industrial sites and mines to waterways and sensitive ecosystems.
What Is Bioremediation?
Bioremediation is the use of natural or enhanced biological processes to break down and neutralise contaminants such as hydrocarbons, fuels, oils, and certain chemicals in soil and water.
Instead of simply removing contaminated material and transferring the problem elsewhere, bioremediation:
Treats pollution at its source
Reduces long-term environmental liability
Restores ecosystems more sustainably
Often lowers overall remediation costs
Drizit applies scientifically supported bioremediation techniques as part of structured rehabilitation programmes.

Environmental Rehabilitation Explained
Rehabilitation focuses on returning affected environments to a safe, stable, and compliant condition following pollution events, industrial activity, or long-term contamination.
This may include:
- Soil and groundwater recovery
- Surface water and wetland restoration
- Removal of residual contamination
- Long-term monitoring and management
Rehabilitation focuses on returning affected environments to a safe, stable, and compliant condition following pollution events, industrial activity, or long-term contamination.

When Is Bioremediation Required?
This end-to-end capability reduces risk, simplifies coordination, and ensures consistent environmental outcomes.
Oil and fuel spills
Chemical releases
Tailings dam failures or leakages
Long-term industrial contamination
Mining and processing activities
Environmental incidents impacting watercourses
In many cases, authorities require proof of rehabilitation, not just cleanup.
