Wastes must be managed properly to avoid negative impacts that may result. Open burning
of waste causes air pollution which is particularly hazardous. Flies, mosquitoes and rats are
major problems in poorly managed surroundings. Uncollected wastes often cause unsanitary conditions
and hinder the efforts to keep streets and open spaces in a clean and attractive condition.
During final disposal methane is generated, it is much more effective than carbon dioxide as a
greenhouse gas, leading to climate change. Therefore, this study describes the possible valorization
of two waste streams into activated carbon (AC) with added value due to copyrolysis. High efficiency
activated carbon was prepared by the copyrolysis of palm stem waste and lubricating oil
waste. The effects of the lubricating oil waste to palm stem ratio and the carbonization temperature
on the yield and adsorption capacity of the activated carbon were investigated. The results indicated
that the carbon yield depended strongly on both the carbonization temperature and the lubricating
oil to palm stem ratio. The efficiency of the adsorption of methylene blue (MB) onto the prepared
carbons increased when the lubricating oil to palm stem ratio increased due to synergistic effect. The
effects of pH, contact time, and the initial adsorbate concentration on the adsorption of methylene
blue were investigated. The maximum adsorption capacity (128.89 mg/g) of MB occurred at pH 8.0.
