Species	T _i	Peak temperature (°C)			Temperature	T ₅₀	R ₅₀	Residue
Species	(°C)	P _MC	P _HEM	P _CEL	of APZ (°C)	(°C)	(wt% min⁻¹)	(%)
C. procera	221	72	–	382	235–405	384	7.23	18.4
P. australis	198	76	320	372	240–390	379	7.40	22.7
R. stricta	240	82	345	400	238–410	393	6.32	17.0
A. tortilis	255	86	330	388	280–410	389	6.93	18.6

These data were extracted from the thermo-gravimetric analysis (TGA) curve with a heating rate 10 °C min⁻¹ in nitrogen
Bold values of A. tortilis for comparison
T _i is ignition temperature, WL is weight loss, T ₅₀ is the temperature at the level of 50% weight loss, and R ₅₀ is the rate of weight loss at T _50, P _MC, P _HEM, and P _CEL that are peak temperatures of moisture, hemicellulose, and cellulose, respectively
T ₅₀ and R ₅₀ according to Chen and Kuo [52]
