Why we are
Producing district heat and electricity through waste incineration is an efficient and climate-sound solution for waste that cannot be recycled. However, incineration of waste generates flue gas waste; fly ash containing heavy metals and chlorides and a contaminated acid. Today the hazardous fly ash is transported to specific landfill sites, especially in closed mines, according to the ”hide and forget” philosophy. This is not sustainable nor in line with a circular green community.
HaloSep offers a unique and sustainable solution managing all the issues of fly ash. The process recovers salt and metals as well as it reduces the landfill volume. HaloSep provides an on-plant solution that can be built up locally at a Waste to Energy plant. It can also
be placed at a site where fly ash from several smaller plants is consolidated. Thereby, HaloSep will eliminate both cost and emissions related to long-range transportation. We now have the opportunity to build for a more sustainable Waste to Energy industry!
Our value proposition
HaloSep enables a sustainable solution for WtE plants to turn its hazardous waste into usable material to be returned to society which is the definition of a Circular Economy.
Reduces or eliminates landfill and enables recovery of salt and metals.
Converts hazardous waste to useful resources.
Experience and competence
that creates ease of mind.
Long range transportation costs and emissions are eliminated.
Commercially ready for market entry.
On-site WtE plant consolidation of fly ash.
Our contribution to circularity
The stabilized fly ash is a mineral fraction that can be used for construction purposes. The metal fraction will be used as feedstock for zinc smelters. The salt water can be used as road salt or other industrial use. By using a local treatment and recycling solution, long distance transport and export of hazardous waste is avoided.
Our story
-2010 HaloSep originates from Stena Metall’s R&D department with Erik Rasmussen as the inventor. He saw the need for WtE plants to responsibly mange the fly ash that is formed when waste is incinerated to generate electricity and district heating. The fly ash is currently treated as hazardous waste and landfilled at special landfills. This often means long transports and costly handling that is far from the circular economy that society strives for.
2016-2020 With HaloSep technology, the ash is purified, and the result is salt, recycled metals and treated fly ash. A full-scale plant is ready at the large incineration plant Vestforbrænding in Copenhagen. The facility is a project run in collaboration with Vestforbrænding, with funding from EU Life and is therefore referred to as Life HaloSep.
2020 HaloSep AB is founded as a separate company to drive industrialization and commercialization of the HaloSep process. The establishment of a development plant in production size is the stepping stone to offer a sustainable solution for WtE plants all over the globe.
