Palm kernel shell (PKS) is a by-product in the production of palm oil and is often used in the natural biomass energy industries. PKS is often seen in a natural color and with particle sizes normally ranging approximately between 5 mm and 40 mm.
Due to its high calorific value and low ash content, PKS is considered an attractive source of fuel in the production of energy from renewable sources.
Wood chips are small- to medium-sized pieces of wood formed by cutting or chipping larger pieces of wood such as trees, branches, logging residues roots, and wood wastes. Woodchips may be used as biomass and solid fuels.
Wood Pellets are biofuels made from compressed organic matter or biomass. Pellets can be made from any one of five general categories of biomass: industrial waste and co-products, food waste, agricultural residues, energy crops, and untreated lumber.
Wood pellets are the most common type of pellet fuel often made from compacted sawdust and related industrial wastes from the milling of lumber, and manufacturing of wood products such as furniture and construction wastes.
