9 Mar 2026 Energy at the works — part 1 of 2 Heat below 120 °C: the economics of low-temperature recovery Treatment works reject heat all day — from blowers, engines and the effluent itself. Most of it is too cool to be obviously useful. What the second law allows, and what actually pays. Energy · Waste heat · Wastewater

Industrial pipework on a factory building

10 Feb 2026 Zero liquid discharge: the honest cost of the last litre ZLD turns a discharge problem into an evaporation problem. It works — at an energy and capital price that should be paid knowingly, not discovered in operation. Wastewater · Desalination · Industrial · ZLD
