If every household was made to use a composter, it would reduce about 50% of household waste ending up in landfill.
We are a family of 4-5 and compost all kitchen waste and household cardboard in our sealed composter.
We have composters for garden waste, but in this sealed unit we put all of our kitchen waste, including meat, bones and fish. No rats can get in, it doesn't smell, it's kept in a shaded part of the garden close to the house for easy access. It's as simple as putting out the bins.
Your compost bins should be made up of about 70% brown waste: things like cardboard cereal packets, tea boxes, toilet roll holders, egg boxes, torn up envelopes and shredded paper. The rest is all food kitchen waste including egg shells, animal bones, fish, coffee grounds etc...
Wiltshire council actually offer these compost bins (called a Green Johanna) to all their residences for only £50 (discounted from £128.69)
COMPOSTING with a WOMERY:
Another great way to compost is using a wormery.
It can sit just outside your kitchen door. You add little bits of kitchen waste at a time and the little worms munch their way through it, creating the "creme de la creme" of compost. The liquid it produces can also be diluted and used as a plant food.
