Nobody likes a dirty, smelly food waste caddy, but there's lots you can do to keep it clean... We'll look at the liner/bag options available to you.
Cornstarch compostable food waste liners
This is probably the easiest and cheapest solution. Most kitchen food waste caddies take 5 litre or 6 litre bags, and these are often supplied on rolls of 25 or 50 bags. A cornstarch liner is easy to fit to the shape and size of your caddy, whether it's round or rectangular, and will easily spread to fill the base of the caddy.
These are typically available with handles – such as the
Caddy Company 5L bags – or without handles, such as the
All-Green 6L bags. The versions with handles are often easier to tie, especially if you're putting the waste bag in your outside kerbside caddy for collection.
It's always important to understand that cornstarch liners are not completely watertight. They will always leak some moisture through the film, especially if you put a lot of wet waste in the caddy. It's also important to remember that cornstarch liners have a shelf life – in reality, approximately 18 months from purchase if you buy good quality ones as supplied by All-Green.
Paper caddy liners
Some councils or local authorities don't accept cornstarch caddy liners. This is because of the type of machinery they use to process the waste. So, the alternative is to use paper liners.
Now, you might think they will turn into a wet, soggy mess in your caddy, but that's not the case, as the paper is made from wet-strength paper, designed to keep its strength and shape to a certain degree even when it's damp! Paper liners are available in 3L & 5L and 7L & 10L sizes

Now, there are advantages and disadvantages to paper liners. The big advantage of paper is that it is much better if you're using a home compost heap... It's going to decompose much quicker and easier. However, the downside of paper bags is that they are more expensive and, because they are a little less flexible, may be a harder fit in your caddy... especially if it's round or square, as the bottom of paper bags is often rectangular in shape.
