The aim of the present study was to determine the thermodynamic and kinetic parameters of biomass obtained from black pine (Pinus nigra Arn.). The biomass, consisting of twigs with needles and needles alone of black pine, was used. Ultimate analysis
Survey energy efficiency of an industrial system was done. On the base energy audit, the consumption of energy and water was made analyse. On the following audit, there were made choices of energy saving measures, which would lead to proving and econ
