Make your own liquid fertiliser.
Why send your kitchen waste away in a council bin and buy fertiliser - both of which have a carbon footprint - when you can easily make your own. Its fairly easy to get a wormery up and running in our area as long as you get it established over the summer. I bring mine into the garage over winter when it gets freezing and sit it next to the lagged central heating pipes but you can always put it in a shed and/or get an insulated jacket for it too if that is not an option.
I went for a fairly basic option as shown above - just a large tub with a tap on the bottom. It is really easy to get worm wee (the liquid run-off) through the tap, but getting vermicast (the nutritious solid product of the worms digesting your waste) involves diving in and scooping stuff out rather than lifting off a tier. My choice was influenced by cost and I wanted to try something different. With a non-tiered farm not lifting an entire tier off may actually suit you better as these can get quite heavy. Just scoop out manageable hand fulls from the top of the farm into a big bucket and add the lower vermicast layer to the garden. I have used tiered farms before in NZ and they were fine too. Original organics is where I got mine. It is the original version and came with a few worms. You don't get many worms so you need to start off feeding only part of your waste and composting the rest for about a season or two until the worms multiply. As a rough rule: no meat or fish and no cooked products such as bread and cakes but everything else is good. Some people say avoid onions but I find a few dry onion skins as part of a bigger package is fine. Chop big pieces up into small pieces to speed things up. Egg shells are meant to be good. When I rummage through my farm - as you do -the only things that seem to remain are the egg-shells, avocado stones and skins and sweetcorn cores.
