Haztech: Innovative Sludge Management Solutions That Deliver Real Results:

Customers impressed? That’s just a typical day at Haztech.

When others couldn’t deliver, we did. EnviroServ Waste Management (Pty) Ltd’s Haztech team turned a challenging sludge management project into a win for both the client and the environment. After a previous service provider was unable to complete the project, we successfully removed, transported, and safely disposed of 16,992 tonnes of dam sludge, including mercury and fluoride.

Sludge Dewatering Plant: A Breakthrough in Waste Management

In 2024, Haztech launched the Sludge Dewatering Plant, an innovative solution designed to reduce operational costs for industrial sludge management while diverting more wastewater from landfill. By separating water from the dam sludge, the plant also lowers carbon emissions through fewer transport loads and significantly improves overall environmental performance.

By finding an alternative use for this waste stream, we moved it up the waste hierarchy for treatment and reuse, demonstrating that innovation combined with technical expertise delivers tangible results for clients and the environment.

How Haztech Solved Complex Sludge Challenges

When a previous provider could not complete a client project, Haztech stepped in. Our team removed, transported, and safely disposed of 16,992 tonnes of dam sludge, which contained hazardous materials such as mercury and fluoride. Recognising that bioremediation was no longer viable, we developed a sustainable and cost-effective solution.

Following a pilot in 2023, the team refined the design and successfully launched the fully operational Sludge Dewatering Plant in 2024. The plant has delivered significant benefits for the client, including reduced operational costs, decreased wastewater sent to landfill, lower carbon emissions due to fewer transport loads, and improved environmental performance on-site.

Additionally, the recovered sludge is now reused at one of our waste management facilities, enhancing sustainability and providing further operational value.

Commitment to Innovation and Sustainable Waste Management

This achievement demonstrates EnviroServ and in particular, the Haztech team’s dedication to delivering innovative sludge management solutions that provide measurable results for clients. Our approach consistently protects the environment while creating economic value, turning complex waste challenges into practical, sustainable solutions.
