Do I have enough waste to hot compost?
Sunday, 19 August 2012 | HOTBIN Composting
Waste converting into compost depends on the temperature (view our composting speed chart). The HOTBIN is focused on helping you achieve hot composting in the 40-60°c range because this is faster and it has other benefits - review ‘hot composting benefits'.
What is the minimum amount of waste each week to achieve hot composting?
Approximately 5Kg (10 litres, one large or 2 small kitchen caddies) per week.
What happens if I have less?
The HOTBIN will only stay hot (between 40-60°c) with regular feeding of the minimum amount of waste. If you have less, you can still use the HOTBIN, you just need to accept it will cool down. It will fall quickly to 40°c, then 30°c then 20°c, and eventually will fall to the ambient temperature - which in the UK is normally 5-20°c depending on the time of year.
Does it matter if it falls below 40°c?
Possibly not! It is going to happen when you go on holiday anyway! It is more a recognition that you will lose the hot composting benefits for a short period and to get back up to temperature will require new waste to be added.
How much food and waste does a typical household produce?
Every household is different in terms of the food and garden waste they produce. In the table below we use a simple scale of small, medium or large to act as a guide.
Very few users spend too much time measuring the weight or volume of waste, but it may help to know that the average 4 person household with a garden generates 250Kg/year of food waste and 300-400Kg/year of green garden waste. This equals approximately 500-1000 litres of waste (or 1m3 which is a full ‘pallet’ compost box, or 3 full daleks).
Tip 1: If you are going to compost all food waste (eg meats, plate scrapings, stale bread as well as the traditional vegetable peelings and tea bags), match your HotBin to your ‘food waste’ rather than your ‘garden waste’ volumes. It is more important to keep your food waste hot composting in winter, than it is having a HOTBIN that is ‘too small’ to cope with your occasional huge garden clean up in summer.
Tip 2: If in you think you will not have enough waste, here are three suggestions to help:
