Abstract Scope Waste biomass, including pine sawdust, is an important and abundant secondary resource for energy conversion and fuel preparation. This paper reports the use of microwave heating for pyrolysis of pine sawdust for production of biochar. It is shown that the waste biomass sample has a good microwave response with a ramp rate of 40 C min<SUP>-1</SUP> using microwave power of 900 W. The volatile mass is removed in the first 15 min at 400 C and the biochar produced after microwave pyrolysis has a high content of fixed carbon with low volatile and few impurities such as S and P. The biochar, also featured by multiple pores with a large BET surface area, can be used as an excellent microwave absorber and reducing agent for metallurgical use.
