A sustainable Christmas tree made from used plastic bottles has been put up in Thailand.

The 29ft eco-friendly Christmas tree stands tall outside the Siam Discovery mall in Bangkok as mallgoers begin their holiday shopping.

It is decorated using opaque plastic bottles such as milk and shampoo containers, which have been fitted with adorable animal ears, antennae, and antlers to look like cute little aliens.

In line with the theme of ‘circular living,’ the plastic bottles will be delivered to a recycling management system after the festive period.

A plastic waste drop point has also been opened in Siam Paragon, Siam Discovery and other department stores for people who want to join the recycle.

Organised said the Christmas tree was built with the cooperation of Siam Piwat Company Limited and PTT Global Chemical Public Company Limited. It was based on the concept of ‘OneSiam Magic from the Universe,’ which uses cute, alien-like beings as mascots.
