Why Compost?

Composting is one way that you can do your little bit to cut down the waste that goes to the landfill. New research has found that almost half of the food waste in their rubbish bins could have been put in the compost bin. You might be wondering why it is necessary to compost when the waste will break down on the landfill anyway.

On a landfill the volumes of waste are so great that air can not get to the organic waste, so as it breaks down it produces a harmful greenhouse gas, methane, which damages the earth atmosphere. At home when the same waste is composted above the ground, oxygen helps to decompose anaerobically which means that no dangerous methane is produced. So you are not only helping the planet but after about 9 months you get wonderful free fertilizer for your garden.

Composting at home for just one year can save global warming gases equivalent to all the CO2 your kettle produces annually, or your washing machine produces in three months.

What can you put on your compost heap?

THE GREEN: This list are quick to rot and provide essential nitrogen and moisture:
- Tea Bags
- Uncooked fruit and vegetable peelings and scraps
- Old flowers
- Coffee grounds and filter paper
- Old bedding plants
- Grass cuttings
-Salad leaves

THE BROWN: This is the slower to decompose, they provide carbon and fiber and allow air pockets to form
- Cardboard
- Egg boxes
- Egg Shells
- Scrunched up paper
- Fallen leaves
- Sawdust
- Twig, branches and bark

AVOID
these things are best to keep out of your compost heap

- Meat
- cooked vegetables
- dairy products
- diseased plants
- dog poo or cat litter
- nappies
- perennial weeds, or weeds with seed heads.

You need a good mix of Green and Brown for a healthy compost heap. I am not going to go into exact amounts as I find when something is too technical and too prescribed then people don’t even start as it sounds like too much effort. Aim for a good mix of the two. If it is too wet add some more Brown, if it looks a bit dry add some more Green. The Green items will contain bacteria that will generate the initial heat that is required by the process. A healthy compost bin is a living ecosystem. By keeping a good mix of green and brown material you will provide the perfect conditions for a variety of mini-beasts and can let them do all the hard work.

What equipment do you need?

I bought a lidded bucket from the local supermarket and have it handy in the kitchen so that collecting all the veggie and fruit peels, tea bag egg shell etc is really easy. The lid makes sure that the flies are not attracted to it and I empty it every few days.

A compost bin is not absolutely necessary and as long as you have a designated area all compost material will eventually break down. A bin however is a very nice to have compost tool as it helps keep everything in one place and is dark and hot which helps the decomposing process, limits the smell and make produces the compost faster. You can get compost bins from most garden or hardware stores.

When is the compost ready?

It takes about 6-9 months depending on the climate for the compost to totally decompose. You can also get compost activator to speed up the process but it is not totally necessary.
Once your compost has turned into a crumbly, dark material, resembling thick, moist soil and gives off an earthy, fresh aroma, you know it’s ready to use. Lift the bottom of the bin slightly or open the hatch at the bottom depending on the kind of bin you have. Scoop out the fresh compose with a spade or fork. Don’t worry if there are small twig or bits of egg shell still visible this is normal. You can now use this compost in your garden beds, on the lawn, in containers and in your vegetable garden.
