LAT Water says EU emissions rules now push water reuse into industrial permits

LAT Water Technologies says the revised EU Industrial Emissions Directive is making water efficiency and effluent reduction a permit requirement for about 75,000 industrial installations. The company argues its waste-heat-powered evaporation process can help heavy industry cut discharge and freshwater use at the same time.

Why it matters: - The revised EU Industrial Emissions Directive turns water efficiency from a best practice into a compliance issue for large industrial sites. - Operators now face two linked pressures: reduce discharge and cut fresh water use. - Water recovery from effluent can help sites meet both goals while lowering dependence on external water supplies.

What happened: - LAT Water Technologies said Directive (EU) 2024/1785 now affects about 75,000 installations across energy, metals, minerals, chemicals and waste sectors. - EU member states had to transpose the directive into national law by 1 July 2026. - Industrial permits must now address resource efficiency, including water use. - Discharge limits are tied to Best Available Techniques conclusions, which are reviewed sector by sector.

The details: - LAT Water Technologies said the hardest industrial effluents, including high-salinity and mixed-contaminant streams, often require thermal evaporation for final treatment. - Traditional thermal evaporation typically relies on fuel or grid electricity. - LAT's patented process uses low-grade waste heat already available on site, including exhaust gases, cooling water and process heat. - The company says this approach lets industrial sites turn rejected heat into clean water recovery. - Jozef Wallis, VP Commercial EMEA at LAT Water Technologies, said: "Heavy industry has two things in surplus: low-grade heat and difficult water. The revised directive is a strong reason to use one to deal with the other." - LAT says Jacobs Engineering and the Carbon Trust validated the technology at full scale. - LAT says the units have previously been deployed in the UK and China. - LAT Water Technologies said the process recovers clean water and reduces contaminants to manageable solids. - The company says it holds 10 granted international patents. - LAT works with industrial operators and distribution partners in Europe, the Gulf, India, China and North America. - More information is available at the company's announcement and the UK company record at the official registry listing.

Between the lines: - The directive appears to make water reuse a stronger business case, not just an environmental preference. - Waste heat is becoming more valuable as a compliance asset because it can offset the energy cost of treatment. - The policy change may favor technologies that can treat difficult wastewater without adding major power demand.

What's next: - Industrial operators in covered sectors will need to align permit applications and site upgrades with the new resource-efficiency requirements. - Technology vendors that can pair water recovery with low-energy operation may find a larger market as member states finalize national implementation. - LAT Water Technologies is likely to position its waste-heat-driven systems as a route to both permit compliance and water reuse.
