Sludge was pyrolyzed with bamboo sawdust for metal immobilization. Metals were transformed from highly available to stable forms after pyrolysis. Addition of bamboo sawdust in sludge co-pyrolysis minimizes the risk from metals. Co-pyrolysis with bamboo sawdust at 600 °C is suitable for sludge metal stabilization.
