MAEH offers the best in class waste management services for collection, incineration, transport, treatment, disposal and recycling of toxic industrial waste and other materials. It is important that high standards are maintained throughout the entire waste management procedure in order to minimise the impact on our environment. Good waste management solutions will give us cleaner and healthier environments, improved living conditions and sustainable business models.
Waste Collection
Our waste collection services incorporate the highest quality checks and are compliant with the necessary regulations and are supported by our highly efficient Collection and Transportation Support Team to ensure that your waste is collected in a proper and safe manner.
Waste Incineration
Incineration is used mainly in the treatment of hazardous organic liquid and solid wastes, which cannot be economically treated via other methods. MAEH has an on-site rotary kiln incinerator manufactured by ABB/Alstom that is regularly maintained to ensure optimum safety and operation standards.
Precious Metal Refining
We offer a comprehensive recycling system ranging from the recovery and refining of used scrap metal containing precious metals to the remanufacture of those metals into products. Some of these include the recovery of gold, silver, copper, nickel and palladium.
Solidification and Stabilisation
Solidification and stabilisation is a pre-treatment process before the waste is sent for incineration or to be placed in modern eco-landfills. It is a widely used treatment for the management or disposal of a broad range of contaminated media and waste, particularly those contaminated with substances classified as hazardous. This treatment involves mixing a binding reagent into the contaminated media or waste which is an important step in protecting human health and the environment by immobilising contaminants within the treated material. Solidification and stabilisation is a pre-treatment process before the waste is sent for incineration or to be placed in modern eco-landfills.
Recycling and Recovery
Part of our responsibility to the environment is to recycle and recover as much as possible to preserve our earth’s resources. Solvents and spent chemicals are recovered using distillation and separation process. We also conduct these services on organic waste, used oil, and other such chemicals.
