5/6 Waste Audit 4 th March 2011
On the 4 th March, 5/6 conducted a waste audit of Baradine Central School. This involved collecting the rubbish from the day before and using tongs, we sorted it into 5 groups.
The five groups were: Landfill Recyclable containers Organic material Food Scraps Clean paper Metal
We used a bucket and scale to weigh each pile of rubbish.
We recorded these results so we could calculate how much of each type of waste our school generated in a week / term / year!
Everyone in our class worked out how much waste we produced! The results were shocking!
Landfill: Our school produces 2.6kg in one day!! That’s 13kg in one week 130kg in one term And 520kg in one school year!! That’s how much a big fat cow weighs!! This is waste that cannot be recycled, composted or used for any other purpose.
Recyclable Containers In one day our school throws away 1.05kg of recyclable containers!! That’s 5.25kg in one week 52.5kg in one term And 210kg in one year!! That’s the size of a young steer! At the moment, we are adding that to landfill!
Food Scraps In one day: 4.85kg!! That’s 24.25kg in one week 242.5kg in one term 9700kg in one year!! That’s nearly ONE TONNE! That’s how much a Bull weighs! At the moment, that is being added to landfill – we could have a lot of happy chooks if we gave it to them!
Clean Paper Some paper gets taken to the tip to be recycled but there’s still lots that’s just going in the bin! In one day there was 200g Which is 1kg in one week 10kg in one term And 40kg in one year! That’s how much some of us weigh! At the moment – it’s being added to landfill
What can we do? We could do nothing..... We could keep adding 3 tonnes of landfill to the tip each year. That would be easiest..... But one day.... There will be no more room at the tip. This is what happens when people are not responsible with their rubbish:
Or we could recycle.
We could also become more conscious of our own waste!! Every year over 6 million tonnes of rubbish is dumped into the world’s oceans, 80% of which is plastic, and a further 10% of this being plastic bags. With an estimated 46,000 pieces for every square mile of ocean, plastic is responsible for killing 1 million sea birds and over 100,000 sea mammals each year. Turtles, whales and sea birds mistake rubbish for food or get entangled in it, resulting in painful injuries, or even death.
