Collecting food waste to make compost

During the Climate Friendly School workshop, Team Green students decided to focus on collecting food waste and establishing a compost in term 2.

We invited Wastebusters Dr Compost to explain about compost and for some guidance on how to start: a food waste audit. We decide to collect the food waste from two classes for two weeks. It is probably not enough but we are a small group and only have 45 minutes per week!

Week One: We designed a poster, contacted teachers in charge, and sourced bins. We choose a Year 7 and a year 8 class.

Week Two: we installed the bins in the two rooms with the posters on them and talked to the teachers -who had both agreed- so that they promote their use to their students. We created a system and a roster to go and empty the bins.

Week Three: No one had emptied to bins! So we go and do this together, it is quite hard work, smelly! And cleaning the bins is also a messy business.

Week-Four: We go again to empty the bins and weigh the result:

Comments:

  • There were no wrappers in them. That’s very good. Only one paper napkin found in 2 weeks.
  • There is lots of citrus and bread
  • There are many fruit stickers. And we know they do not compost.
  • There is less food waste the second week than the first. Did people forget? Is it too difficult to  open the lid?
  • It is difficult to wash the bins. We need a brush. And a place to empty the water with food leftovers in it. People will wash their own bins so we need to make it easy.
  • A teacher comments the bin were too big for her class. So we put it out. Will we have a bucket -with lid- per class or a central bigger bin?

Well done everyone for planting 44 trees!

44 trees has been planted in 2 hours by all MAC students in the past month. Thank you to the diggers, bucket carriers, and tablet holders and all helpers. We earned these trees because we recycled 8 tons of paper in 2011 and 2012.

Thank you to Paper4Trees 

Getting money from companies who want to reduce their carbon footprint, they buy native trees and offer them to school to reward them for their recycling efforts.
Since Paper4trees first started in 2001, kiwi kids have recycled over 25,000 tonnes of paper and cardboard and planted over 100,000 native trees! http://www.paper4trees.co.nz/
