Reducing Waste

Thanks to a grant from the State Government’s Department of Natural Resources and Environment, this year we have been able to offer students from our 24 Carrot schools waste minimisation workshops.

Each workshop day comprises three, hour-long activities that students move through in small groups of 6-8, before coming together to share a fresh, seasonal meal they have helped to cook. The focus is fun, hands-on, interdisciplinary learning that embodies key ideas about waste minimisation and sustainability.

In the south, the workshops are hosted as excursions to Material Institute’s market garden and learning hub in Bridgewater. Here, students are given a tour of the site and shown the various waste minimisation strategies in place — including composting, seed saving, reusing seedling pots and using solar energy to melt waste beeswax from our hives for use in candles and beauty products. 

Students then make their own ceramic keep cups, body spray from natural ingredients grown on site; and cook together using produce from our market garden and ingredients typically considered ‘waste’ - such as stale bread

In the north and north west, the workshops are delivered as school incursions inside the schools, with Material Institute’s team of facilitators running the activities at school sites. Students learn how to grow oyster mushrooms on waste materials such as sawdust and straw and to make their own paper from waste paper. They also cook lunch together and learn how to pickle and preserve excess produce.

So far, the following primary schools have had a chance to take part in the program: Brighton, Clarendon Vale, East Derwent, East Devonport, East Tamar, Gagebrook, Glenorchy, Goodwood, Moonah, Risdon Vale, Romaine Park, Springfield Gardens, Triabunna District School and Warrane. We can’t wait to continue next term delivering these to even more of our schools!
