WASTE SERVICES

TEC offers the highest quality services for the collection, incineration, transport, treatment, disposal and recycling of toxic industrial waste and other materials. It is important that a high standard is maintained throughout the entire waste management procedure in order to minimise the impact on our environment. Good waste management solutions result in 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. TEC has an on-site rotary kiln incinerator manufactured by ABB/Alstom that is regularly maintained to ensure optimum safety and operation standards.

Biological Wastewater Treatment

This kind of wastewater treatment is generally done using efficiently designed Sequencing Batch Reactors to allow industrial effluents to be disposed of without endangering human health or causing unacceptable damage to the natural environment. TEC’s wastewater treatment consists of a combination of physical, chemical, and biological processes to remove solids, organic matter and sometimes, nutrients form wastewater, until the accepted regulation parameters are met.

Physical Chemical Treatment

Current methods for the treatment of inorganic liquid waste are being used in TEC. Each process is customised to match the different characteristics of the waste, which include corrosive, reactive, and oxidising substances, or a combination of these. TEC also recovers metal hydroxides from spent etchant waste.

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.

Solidification and Stabilisation

Solidification and stabilisation 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, and 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.

Laboratory and R&D Facilities

TEC has its onsite fully equipped laboratory that supports the facility by conducting routine and non-routine analysis in a timely, professional manner. Physical and chemical analyses performed in the laboratory include fingerprint tests of all incoming waste, wastewater parameters, solvent, oil and solid analysis of all types of wastes.

Precious Metal Refining

TEC works in collaboration with Dowa Eco-System Singapore Pte Ltd in precious metal recovery and refining. Some of these include the recovery of gold, silver, copper, nickel and palladium.
