GRST (Green Renewable Sustainable Technology) is a lithium-ion battery technology company with R&D and giga-scale manufacturing operations in water-based manufacturing and recycling of batteries.



Our award-winning patented WATMAR³ technology is operating at giga-scale replacing the toxic, expensive, and polluting solvents and fluoropolymer binders which hold the battery together with simple water and a water-soluble binding composite.



We make battery manufacturing and recycling safer, cheaper, and cleaner.



We remove the risk of emissions for VOC (Volatile Organic Compounds) and PFAS "forever chemicals" from electrode production.



WATMAR³ works for all battery chemistries and can be quickly, cheaply and easily integrated into any conventional battery factory.
