loosey, it does burn and it doesn't smell (no more than peat anyway)
the most difficult thing though is drying it out, i used the ready made 'coal' dried out over the summer, shelved with plenty of space between each 'nuggut' on a metal shelved cage, take care to move it in out of the rain though.
the paper log makers, in my opinion are difficult to use especially if you have straw bedding.
i've already started stacking 'coals' for next winter only using the 'coals' though as the wet bedding takes too long to dry and makes for better compost !
