"Mainichi" was a plantable newspaper launched in Japan in 2016.

Produced using recycled paper embedded with flower and vegetable seeds, the newspaper could be planted after reading to grow into actual plants.

In Japan, plantable newspapers have become a popular trend promoting sustainable culture. These innovative newspapers are made from biodegradable materials like recycled paper and seeds, functioning as regular newspapers before being planted to transform into plants. The initiative aims to reduce the environmental impact of printed newspapers while promoting new plant growth. This eco-friendly concept has been well-received by the Japanese public and has helped raise awareness about adopting more sustainable daily practices.
