The Strengite Process was invented by David Sevier. He invented the Strengite Process to address the large amounts water that closed loop cleaning uses and the pollution that it causes. He was awarded a patent for the Strengite Process in 2021.

David Sevier is a water treatment chemist who has been developing and writing water treatment product lines since 1984. He has also done extensive work on carbon capture and storage. This includes work on air-based carbon capture which has the potential to turn petrol into a carbon neutral fuel. He has patented a carbon capture process from power plants that has the lowest input energy of all carbon capture processes. He led a team that developed a carbon capture and utilisation process that represents the lowest cost process to capture and store up to 1/3rd of a billion tons of CO2 per year. The team he led developed and patented a method to clean up waste gypsum from fertiliser production which is the world’s largest solid waste problem.
