Compost Bins
There are numerous types of compost bin
They can all work just as well as each other
3 Main Steps to Composting
Step One - Placing your bin
Step Two - What can go in
Step Three - Making good compost
Step One - Placing your bin
The bins are best sited on a level, well drained spot
This allows excess water to drain out This allows better aeration Worms can get in easier Placing a compost bin in a partially
sunny spot can help speed up the composting process
Step Two - What can go in? The compost bin relies on what you put in
Vegetable peelings Fruit waste Tea bags Plant clippings Grass cuttings
These items are considered “Greens”. These provide
nitrogen and moisture to the compost heap.
Step Two - What can go in?
What else can go in?
Cardboard Egg boxes Scrunched up paper Fallen leaves
These are called “Browns”. They rot a lot slower and
provide fibre and carbon. This material also allows
pockets of air to form.
What Cant go in?
x No cooked food No diseased plants No animal faeces No nappies Limit the amount of leaves
Step Three - Making Good Compost
Essential to get the right mix This means right mix of Greens and
Browns If the compost mix is to wet then
add more browns If its to dry then add more greens Air can be added by adding
screwed up paper
Compost Essentials
Air Water Food
The items we add to the bin provide these. Air, water
and food are essential in order for the materials to break
down.
The materials biodegrade, this means to rot down.
What else is in a compost bin?
Worms Beetles Ants Slugs Centipede Earwigs
The general rule is the more diversity of creatures in your compost bin the more quickly it will break down.
Worms and Beetles
Q. What do they do?
A. Worms eat away at the matter in the compost bin and break down the material. They also help to add air to the soil.
Beetles and Flies also eat away at the matter and work together to turn this waste into compost.
Problems with the mix
If there is not enough air in the compost bin then the
waste will become anaerobic.
Anaerobic means in the absence of oxygen. This is when biodegradable waste will start to produce methane. Methane is a greenhouse gas which is contributing toward climate change.
