Mottainai in Japanese means "do not waste". It is an ancient Buddhist concept that has become a traditional cultural practice. Chunk® is a symbol of the realization that you need to protect and understand the value of many things in life, before thoughtlessly spending or destroying them. This applies to everything: natural resources, material values, even forces and thoughts. Mottainay is gratitude for the environment, the need to give a second life to things, not waste resources, and teach children to respect the world.
