Projects & Case Studies

Mercury Contaminated Waste Management

CWM launched Sri Lanka's first fully compliant solution for mercury-contaminated wastes, including laboratory waste, fluorescent bulbs and industrial effluents.

Through strategic partnerships with global leaders, we ensure safe collection, ISO-aligned pre-processing and responsible export for mercury recycling, protecting people and ecosystems.

Toner Cartridge Recycling

Addressing a nationwide gap, this program enables the full recycling and material recovery of used toner cartridges, including carbon powder.

All components are processed for reuse or sustainable disposal, substantially reducing landfill burden and supporting a local circular solution.

XRF Technology Integration for Waste Stream Analysis

With the introduction of advanced XRF spectrometer-based technology, CWM can accurately identify metals and key substances in sludges and complex waste streams.

This enables optimal design for safe disposal and recovery while enhancing compliance, accuracy and operational efficiency.

Precious Metal Refinery Establishment

Our state-of-the-art facility specializes in extracting gold, silver, platinum, palladium, copper and nickel from electronic waste.

By recovering valuable metals from discarded electronics, we transform e-waste into new opportunities while reducing dependence on imported raw metals.

Chemical Manufacturing from Refinery By-products

Circular Chemistry in Action

By leveraging refinery residues, CWM produces essential chemicals, notably copper oxalate and copper nitrate.

This approach enhances material reuse, cuts waste and maximizes the utility of recovered resources.

Zero Chemical Discharge System

Sri Lanka's first Precious Refinery operated by CWM incorporates a zero chemical discharge closed-loop system.

By consistently collecting, purifying and reusing chemicals, sometimes improving them with targeted additives, we minimize material use and waste.

The result is lower operating costs, conserved resources and a clear demonstration of environmental stewardship and operational excellence.
