The Holocaust
To dispose of tear gas pellets, it is recommended to place them in a plastic bag or container with a secure lid and then contact your local hazardous waste facility for proper disposal instructions. Do not attempt to burn, crush, or puncture the pellets as this can release harmful chemicals into the environment.
The calorific value of one litre of extra light oil amounts to 10 kWh, as does the calorific value of 1m3 of gas. It is therefore true that: 2kg pellets ~ 1 litre extra light oil ~ 1m3 gas. In terms of price pellets do significantly better than oil and LPG.
