Today was the annual clean out of the HotBin composter we use for food waste. That is, food preparation waste not wasted food. We cook from fresh, no ready meals or ultra-processed food except for the occasional bag of frozen oven ready chips!
That means we generate around 5-7Kg of compostable material, never ‘waste’, a week or 260 -360Kg a year! Teabags are included as we use Clipper which have 100% compostable bags or use leaf tea. We also include a small amount of discarded cooked food but there is not much.
Some myths about composting food ‘waste’:
1. You must not compost cooked food as it attracts rats. In over 30 years of composting I have only ever seen one rat which was asleep in the top of a bin used only for garden waste.
2. You cannot compost rice as it is full of bacteria. I think that has got around the internet because of warnings not to reheat cooked rice. Any active compost bin is full of bacteria, they do all the work and generate the heat.
3. Composting food stinks and attracts flies. Not in our experience if you do it right in a bin designed for the job.
4. It’s better to give it to the council. Never! It’s far too valuable to give away. Home composting cuts costs and reduces CO2 emission from the large lorries use to cart it away. It also helps to grow bigger, more nutritious veg and completes the cycle from ground to food back to ground.
5. Add eggshells to the compost to provide calcium. More advice from the internet which is totally wrong. Eggshells dot not breakdown however long they are in the bin. The shell is not water soluble and cannot give calcium to soil.
Here is an egg shell I dropped in this time last year!
When we opened the bin there was a solid mass of completely composted material or should I say SOIL because that is what it is now. It amounted to two heavy wheelbarrows full which went straight onto a bed to be distributed later. It is rich and full of nutrients and well worth the minimal effort to make it!
We use a Mk1 HotBin, we have had for a few years. It works well enough but it could work even better with increased airflow and a slight modification is planned before refilling starts. The latest Mk2 model has the changes incorporated. They are not cheap but have a number of features that makes them ideal for household use e.g. they have a tight fitting lid with a charcoal filter it take out any smell. Full details available here.

There is also a new make on the UK market, the Aero Bin Hot Composter from Australia. The Centre for Alternative Technology use the large version for their food waste and last summer it was working very well. More information here.
Compost tumblers also work but can be hard to turn when they are full unless they have a geared handle.
