About Us

As high technology and high urbanisation, it causes weather and ecology change rapidly, "environmental protection" and "sustainable development" are the one of the focal issue of global concerning.

The wastewater capacity is around 50,000,000 tons/year.
The recycled water volume is around 2,000,000 tons/year.

The hydrofluoric acid wastes recycling is around 12,000 tons/year.
The ammonia nitrogen wastewater recycling is around 102,816 tons/year.

The cryolite yield is around 2,208 tons/year.
The ammonium sulfate yield is around 30,000 tons/year.

Retech team was based on water system to develop in the direction of chemical waste reclamation and green chemicals in the factory of circular economy. Retech team started to have the idea of elemental fluorine recycling and reusing in 2010, and started to apply Taiwan, USA and China’ patents in 2012. TSMC invited Retech to join resource evaluation in 2017, and completed the world's first cryolite conversion system using waste hydrofluoric acid in a semiconductor factory in 2021 and we started to produce cyolite in September 2021. It was a beginning of urban mining and industrial recycling of waste chemicals into raw materials.
Retech accomplished to put the technology of recycling and reusing apply on production plants of clients and let them start to carry out "Net Zero Emissions" from the manufacturing plants.
Retech team turns the produced green chemicals into industrial raw materials and our resource sustainability and net zero carbon emissions in urban mining have entered the world trend train in the future, and we also play an important role in this area.

Facing the future, ReTech will insist the concept of "waste reduction and recycling" to the professional development. "Carbon reduction, Water conservation, Recycling" are our sustainable development strategy. Our spirit of continuous innovation is the best partner for corporate water resources and ESG sustainable development.
