Jang Dong-min personally introduced a new eco-friendly product on a broadcast.

In episode 961 of MBC's variety show "Radio Star," Jang Dong-min unveiled the new product alongside existing ones and explained the development process aimed at reducing plastic usage. He emphasized, "I carved grooves into the container I made. I minimized the mass as much as possible," highlighting the reduction of the 500ml water bottle's weight from 10g to 1.5g. Jang Dong-min added, "Using 10 water bottles has the effect of not using one water bottle." He also announced that the product is scheduled to be released on the market starting next month, according to the broadcast.

Jang Dong-min previously received the Korea Environmental Industry & Technology Institute Director Award at the "2023 Environmental Startup Competition" hosted by the Ministry of Environment for his PET bottle label separation item. The PET bottle one-touch detachable label he developed allows the label to be removed simultaneously when twisting the bottle cap. This idea was patented in 2021 and officially registered last year, and based on this, he founded an eco-friendly company earlier this year.
