| General household waste is collected once a week but it must be separated into burnable and non-burnable items. |
| In order to convert soft powdery coal dust into a solid burnable unit, a special binding agent had to be developed. |
| He went off to drag charred masses of burnable stuff from the burned-out first forest fire. |
| After sufficient burnable material accumulates in and upon the soil, a hot fire can occur. |
| In the mean time, the storehouse, and everything the yard contained which was burnable, was on fire. |
| The butchers, who play a key role in A burnable Book, are a great case in point. |
