Revolutionary Technology of Deodorizing by Light! We AreTackling on SDGs

P hotocatalytic deodorization device “PCF® Hybrid” is a brand-new purification system for exhaust air with malodor or nasty smell. It consists of TiO2 (titanium dioxide) stabilized on the special catalyst support,  UV light source and auxiliaries which are functionally assembled through patented technologies.

Activated Carbon Filtration Supported by the Regenerative Function for Successive and Efficient Treatment of Wastewater

MEDICAL NANOCOAT: Multifunctional Hygienic Coating Delivered by Nanotechnology

Stable and Regenerable Ti-based TiO₂ Photocatalyst of Multiple Application for Environment

Yield Co., Ltd. has developed a multi-functional material “Titanystar” which decomposes harmful organic compounds by the photocatalytic technology, and it can be effectively applied to cleaning of undrinkable water into safe drinkable water. This photocatalytic reaction derives from a uniform layer of titanium dioxide (TiO2) generated upon metal titanium, by the special technology of surface oxidation.

Ion Exchange Membrane for Electrodialysis:  Purifying Water

Issues surrounding water have increasingly become serious worldwide caused by drought and other meteorological phenomena as well as rise in salt content in groundwater. However, securing good quality water is important from the perspective of people's health and sanitation.

An Efficient Removal Device of Particulate Matter and Black Smoke by Semiparmanently Use

Cassette type DPF "MoCobee CT" is the retrofit device for black smoke

removal attached on diesel engine, which can easily remove 99.9% of black smoke regardless of use condition and engine type.

This diesel particulate filter (DPF), developed by COMOTEC Corporation, consists of DPF body and the filter regeneration device with electric heater.
