I hope my suggestion to you will help you out.
I opted for Nature's Head Dry Composting toilet Once you start using it you will see that it combines with the heat regulator to speed up the composting process.All of the excrement gets stored deep inside the toilet and this leaves it odorless when used.It provides versatility in its function.
