How do we do it?

Advanced Oxidation Process



An extremely powerful oxidising agent that breaks down to pure oxygen after use.


The energy of photons in short wavelength light excite and ionise molecules, changing their chemical structure.


Natural Earth elements activate powerful chemical reactions that are regenerative and non-toxic.


Micro bubbles with shock waves as hot as the surface of the sun, and pressures exceeding 1500 times that of Earth's atmosphere.


At Greenthread Solutions our team are passionate about making our planet a safer and healthier place.
