The Buy & Burn is a program where fees are collected and used to purchase the token. After the purchase has occurred the tokens bought will be burnt. This is where they are removed from the circulating supply.
For Bonfida, an example is transactional fees where it receives 20% of that revenue from Serum. That 20% is put towards the monthly Buy & Burn.
This occurs at the end of every month.
