So what is a waste audit? What did we discover? Is there any changes we could make to further reduce the waste our school produces?
What is a waste audit?
The audit, along with an analysis of data collected, will assist the school in making further improvements to waste reduction initiatives.
We held on to the rubbish generated in the school over one day. Then we gathered it together and analysed the types of rubbish we are creating, collecting data and seeing if current practices reduce waste going into landfills.
We weighed each kind of waste, keep records and discussed the data to help us identify where we could improve and then talk how we could make any changes needed. We have shared our findings below...
What did we discover?
Key things we discovered:
Tahi: most of our Paper waste was compostable, though we produced less that 200 g of paper waste with most paper being recycled in the Zero Waste/Paper for Trees bins in the school. We did discover a lot of this paper was only used on 1 side though.
Rua: Most of our rubbish was plastic packaging (300 g). Quite a bit of plastic in the bins was recyclable.
Toru: The majority of our waste was food waste (about 1 kg), food scraps that would usually go home in lunch boxes, maybe to families own chickens, compost bins or rubbish bags-landfill.
Wha: Most of the rubbish collected as Litter was plastic packaging, bags or paper.
Rima: A lot of the rubbish we gathered on our tarp wouldn't doesn't go to landfill. Mr B said we use 1 yellow landfill bag a week.
What can we change?
We would make the following suggestions to our school community:
Tahi: Lets try composting our paper hand towels as they would break down. As long as they are only used for drying hands there wouldn't be any reason they could also go in the compost.
Rua: School chickens could be fed a lot of the organic food waste generated at school.
Toru: We could place bins outside for food scraps-labelled Worms, Compost and Chickens.
Wha: Re-usable bags could be re-used instead of thrown away. We could also use paper bags or the organic wrappers that Room 2 made earlier in the year.
Rima: Instead of buying the mini chip packets, use a lunch box with small compartments-buy bigger chip packets and divide the chips up yourself because you will probably get more. Ask Mum or Dad to try crackers, peanuts, raisins and other things instead.
Ono: Re-educate our school families in the newsletter, website, Facebook, Whisper and at Assembly on making less waste for our landfills.
The Art of Re-using things like: Old Tin cans
By cleaning them, peeling off the advertising labels, nailing holes in the base for water drainage, painting with black board paint, tying on special string using a florist's bow, filling with a mix of compost and soil before planting in herbs we created a cool affordable and thoughtful gift for someone's kitchen.
