Additional Info

These lessons were created in partnership with Planet Ark & Coles.

Coles is a Major Sponsor of Planet Ark's National Recycling Week, which was established in 1996 to encourage Australians across the country to engage in recycling education - improving recycling habits and keeping valuable resources out of landfill. They became involved with Planet Ark's National Recycling Week as a part of its Sustainability Strategy to minimise its environmental footprint.  

The strategy includes two focus areas, Together to Zero and Better Together. Together to Zero sets out ambitions across the key sustainability areas of climate change, waste and hunger. Better Together ensures the wellbeing of employees, suppliers and community and works towards positive social change. Its goal is to support all Australians lead healthier, happier, and more sustainable lives.
