Wood materials used for outdoor facilities, which we often think of as eco-friendly wood, are in fact treated with chemical preservatives to prevent corrosion. This is becoming a social issue, as such materials are said to release poisonous heavy metals that are fatal to the ecosystem and the human body.

In addition, half of the world's wood production is still being used as fuel. In other words, contrary to the perception that trees absorb greenhouse gases, wood materials are contributing to global warming and desertification. Wood plastic composite, a natural substitute, is rapidly growing due to the ban on the use of preservative-treated wood (CCA), which threatens the environment and is harmful to public health.

In the future, with growing interest in children's health and the environment, consumers' preference for WPC is expected to increase. In the coming low-carbon society, wood plastic composite will contribute to greenhouse gas reduction and help protect forests as an alternative to wood.
