Can I compost...
Human faeces?
No.
While the faeces of some animals (like chickens, pigeons and pet rodents) can be added to the compost heap, it's best to avoid pooping on your own garden compost heap.
It's like to attract potentially undesirable insects and cause a bit of a whiff and pathogens and bacteria might not be broken down by the normal composting process (particularly in climates like the UK).
If you want to go down the number two route, it's better to have a purpose-built composting toilet.
