In my tiny little garden I am lucky enough to have my own compost bin so that we can recycle our kitchen vegetable scraps and fallen leaves back into dirt.
However, if you do not have room for a compost bin you may like to try a bokashi bin or a wormery.
Unlike traditional composting a Bokashi bin can also handle food wastes such as meat, dairy, and cooked food scraps. It is a kitchen method that works with anaerobic microorganisms in a kind of fermented bran that break down the scraps in as little as 4 weeks. It is very popular in cities and even friends in London have had one. You can buy one from Amazon
Worm composting is an efficient method of turning kitchen waste and small amounts of garden waste into nutrient-rich compost and a concentrated liquid fertiliser. However, it is not a substitute for conventional composting. There are a few drawbacks of a wormery in Amsterdam mainly that the worms will die or decline if the temperature falls below 10C degrees, when neglected they can cause odors, and they sometimes escape their home.
I would highly recommend that if you are making a compost heap that you invest in a good bin. In the past I have used buckets with holes in them but they filled up very fast and sometimes produces an awful odor. The one we have now is store bought and very large. The compost gets quite hot as it is black and attracts the sun too. After some time the scraps will decompose and dirt will be available for you to use in your garden.
