Surface modification of biochar derived from gaharu waste for the treatment of final discharge leachate / Siti Zaharah Roslan

In current years, worldwide demands for products based on gaharu have continuously increased especially in the production of essential oil. In future, the growth of gaharu processing in Malaysia is expected to be in increasing pattern. In the meantime, the production of gaharu oil yielded huge amount of waste in the form of woody mass due to the low ratio of oil yield over the amount of agarwood used. As one way to overcome this problem, this research came out with production of biochar using feedstock from gaharu waste.
