Wood pellets and briquettes for fuel (including transport services)

The wood fuel pellets shall be manufactured from softwood and/or hardwood sawdust; they are ideal for automatic, metered feeding, with adjustable flame and temperature settings to ensure consistent and convenient operation of the heating system. The pellets are produced by compressing sawdust into granules.

The pellets shall be packed in 15 kg bags, labeled with the product name and specifications, and shrink-wrapped on pallets containing 66 bags (990 kg).
