AFAIK, there's no added binder, for making briquettes out of wood chips the inherent lignine is enough.
Taking naturally moist wood chips, compress them under so great pressure that the heat fuses the lignine,
and the water steams off. -Yup - hot enough to burn a bare hand if done properly...
Take out and let cool individually.
Last step apparently important, as there's been a few fires at plants over here,
when they've stacked them on pallets a little too early...
Guess some internal pyrolysis sets in when pressing and if not cool enough and stacked too thick & wide,
the temp could rise fast enough to set the whole stack afire.
Hence the russian DIYer in the movie has to wait quite a while for his briquettes to dry out,
as his 1-ton scissor jack doesn't really make the briquettes steam off all the water...
