FYI these are the expected running costs of iCompost
Electricity costs about R1/cycle if on Eskom (uses 0.7kWh)
Filter refills cost R100 and may need replacing every 4 months if you are running it 3 times per week.
Compost Activator is R60/595g which lasts 35 cycles. (works out to R1.71/cycle)
Some people may produce more or less waste so it depends on your household's habits, but generally it doesn't cost much to run and is still less costly to the environment than throwing food waste in the bin.
