Cogeneration in Hrast factory
The factory in Strizivojna is one of the most significant manufacturers of hardwood parquet in Croatia. In the manufacturing process a larger quantity of wood residue is generated which is then briquetted and placed on the market as fuel (dry sawdust), used to generate heat energy (dry and wet sawdust) or stored in the disposal area.
The project includes the construction of a cogeneration plant (simultaneous production of heat and power) which would satisfy energy requirements of the drying plants and electrical system. Surplus energy produced would be fed into the network to achieve additional profits.
The project solves two basic problems of the factory: supply of low-cost electricity and management of unusable wood waste. Specifically, electricity supply is provided by HEP and by production in diesel units, which results in high prices. The construction of a cogeneration plant would also solve the problem of waste in the form of wood residue which would be used as fuel for the cogeneration plant.
In addition to economic benefits through lower electricity price, selling of surplus energy, higher profits, the project reduces significantly emissions of pollutants into the environment.
