    The first batch looked like wet cardboard or paper going in the mixer, but was black when he poured them. Did he add carbon or coal dust and I missed it?

    More broadly, what are good recipes for fuel briquettes?

    Not so sure I have the time to go to the trouble of making them? However, I have retirement coming up and a nice open fire in my shed. I'll have time on my hands then.
    I have a 1972 Land Rover Series III Truck Cab/Pick-Up and a 1962 Land Rover Series 2a Carawagon Camper.

    Recipe would be a great idea, especially what they use as a binder to hold it all together. Might be a good secondary use for my can crusher...

    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.

    2 cents

    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...
