CMA addresses the challenges of decontamination with specific attention to local factors, including regulatory frameworks and industrial relations, environmental considerations, and local community and key stakeholder interests.
Liquid Waste Drain-Down & Removal
CMA delivers comprehensive liquid waste drain-down services for industrial decommissioning projects. Our capabilities include the systematic removal of lubricating oils, hydraulic fluids, and fuels from gearboxes, transformers, vessels, and heat exchangers, as well as acids, caustics, and process chemicals from water treatment and production systems. We deploy vacuum truck operations, controlled flushing, and full waste characterisation to ensure compliant disposal through licensed receival facilities.
Prescribed Industrial Wastes (PIWs)
Safe removal of structural and environmental contaminants, including impacted soil, tailings waste and sediments. Other PIWs include friable and non-friable asbestos; Chromium 6; PFAS; PCB impacted materials and equipment; heavy metals – cadmium, mercury, lead; chemical solvents, pigments and sludge; residual hydrocarbons and oils; NORMS and radioactive waste; and refrigerant gases.
CMA implements rigorous waste management systems across all decommissioning and demolition projects. Our approach encompasses full waste characterisation, segregation at source, and chain-of-custody tracking from generation through to final disposal or reuse. We deliver comprehensive compliance reporting, waste registers, and diversion metrics that demonstrate regulatory adherence and support client sustainability objectives.
Industrial Cleaning
Safe and efficient solutions for an array of contaminants and Prescribed Industrial Wastes involving sector and site specific industrial plant. Sand, dry ice and hydro blasting; vacuum excavation; laser, foam and immersion cleaning.
Hazardous Waste Treatment & Abatement
CMA addresses the challenges of decontamination with specific attention to local factors, including regulatory frameworks and industrial relations, environmental considerations, and local community and key stakeholder interests.
Our hazardous waste treatment contracting capabilities include surveying and analysis of waste streams; air and health monitoring, including engagement of independent occupational hygienists; NATA accredited laboratory analysis; full encapsulation and HEPA filter negative air units; 5 Stage wet decontamination units; containment cell construction and management; and certified hazardous waste transport, tracking and reporting.
Asbestos
CMA is a Class A and Unrestricted licenced asbestos removal contractor with 35+ years of experience designing and delivering industrial asbestos and HAZMAT/HAZCHEM abatement work programmes. Our capabilities extend to the safe removal and disposal of all forms of dangerous goods and hazardous waste that can be present throughout heavy industrial plant and facilities.
Lead & Heavy Metals
CMA delivers comprehensive lead and heavy metals remediation across industrial facilities, including smelters, refineries, and power stations. Our teams are trained in encapsulation, controlled removal, and specialist disposal methodologies, ensuring compliance with exposure standards and environmental regulations while protecting workers and surrounding communities.
PFAS, PFOS & Forever Chemicals
CMA provides end-to-end PFAS investigation, containment, and remediation services for contaminated soils, groundwater, and infrastructure. With expertise in firefighting foam-impacted sites and industrial facilities, we employ proven methodologies for PFAS management, disposal pathways, and long-term monitoring to meet evolving regulatory requirements.
Mould
CMA delivers industrial-scale mould remediation for facilities affected by water ingress, flood damage, or prolonged shutdown conditions. Our qualified teams undertake containment, removal, and decontamination works in accordance with industry guidelines, restoring safe operational environments while minimising disruption to client operations.
NORM & Radioactive Substances
CMA holds the licences and expertise to safely manage Naturally Occurring Radioactive Materials (NORM) and Low Specific Activity (LSA) scale found in oil and gas, mining, and mineral processing facilities. Our radiation management plans ensure compliant handling, transport, and disposal through approved pathways.
Mercury, H2S & Pyrophoric Materials
CMA specialises in the safe decontamination and removal of mercury, hydrogen sulphide, and pyrophoric materials from refineries, gas plants, and petrochemical facilities. Our methodologies address the unique hazards of these substances, incorporating atmospheric monitoring, inerting, and controlled cleaning to eliminate risk during decommissioning activities.
