Waste management is an integral part of the circular economy scheme. The forestry sector contributes waste from land clearing, planting, silviculture procedures, and processing forest products. Since silviculture aims to increase plantation productivity, thinning waste is often an environmental issue. Conversion of waste into valuable products is allowed to reduce waste in the forestry sector. Thermochemical technology is included in the valuable product improvement strategy. In the present study, activated carbon has been produced using teak plantation thinning-waste material from the 5-year-old class. Wood with a diameter of less than 10 cm and 30 cm in length as carbonization material. The carbonization was carried out by a drum-kiln for 10 hours. Teak charcoal was left in the reactor overnight, then the particles were reduced to below 5 mm in size. Activation temperature variations were set at narrow intervals of 750 and 800 °C. The holding time applied was 15, 20, 60, 180, 180, 210, and 240 minutes. The iodine adsorption behavior observed the effect of activation parameters. This study confirmed the improvement of the adsorption properties, which was increased from 686 mg/g to 699 mg/g. Prolonged holding time resulted in a sharp increase in iodine adsorption. This study's highest absorption of activated carbon was 887 mg/g.
