Additional info

Planet Ark’s National Recycling Week started in 1996 to bring a national focus to the environmental benefits of recycling. This highly regarded annual campaign continues to educate and stimulate behaviour change by promoting kerbside, industrial and community recycling initiative. It also gives people the tools to minimise waste and manage material resources responsibly at home, work and school. In partnership with Planet Ark, we have developed lessons from early learning through to year 10 to help educators bring these important topics into the classroom.

National Recycling Week is held in the second week of November each year but you can recycle all year-round with these lessons which were designed to be used at any time. Click here to find out more about National Recycling Week and the Schools Recycle Right Challenge.
