HALOSEP

TURNING HAZARDOUS WASTE INTO VALUABLE RESOURCES

HaloSep introduces a cutting-edge technology to purify and refine hazardous waste from flue gas cleaning, known as fly ash and scrubber liquid, which arises from waste incineration at waste-to-energy plants. Through the process, this previously hazardous waste is converted into new, valuable resources, while at the same time significantly reducing the environmental impact.

Many homes and premises are currently heated by district heating. Production of district heating and electricity through waste incineration is an efficient use of resources that would otherwise be lost. One challenge, however, is the large volume of hazardous waste, known as fly ash and scrubber fluid, that arises from cleaning the flue gases. Through the HaloSep process, it is possible to treat the hazardous waste and extract zinc and other fractions that are useful in society.

HIGHLIGHTS 2021/2022

FIRST FACILITY IN OPERATION

HaloSep has established the first facility in the world that efficiently separates metals and salts from fly ash. The facility has been built together with one of Copenhagen's largest combined heat and power facilities, Vestforbrænding, where around 13,000 tonnes of fly ash is processed every year to extract zinc, salts and purified ash ready for the commercial market. With reference to the HaloSep process, Vestforbrænding was awarded the “Verdensmålsprisen” by the Danish Waste Association in March 2022.

NEW DEVELOPMENT FACILITY IN GOTHENBURG

A new development facility in Gothenburg, Sweden, was established and will start operating in early 2023. The objective is to continue developing the HaloSep process to further increase circularity and the recycling of fractions into society.
