1. The hardware Store bought storage cointainer. This is not a magic plastic barrel that does the work for you, its as its says A storage bin. All composting takes work. You can purchase a Compost bin for about €20.
2. Hot Composting, I suggest this is done in specially designed conainer rather than a pile. There is less work but you will spend upward of €250 for a cointainer. These bins produce compost roughly 30 times as quickly as a standard compost bin.
3. Vermincomposting/Worm Composting. This is an expensive way to compost and is very difficult to master. If you do go down this route and do manage to over come all the obstecles (worms are not easy creatures when they are unhappy) you will make the most wonderful nutrient, microbe rich compost.
