Table 2

Main properties of different MSW feedstocks.

	Feedstocks
	<1 cm; fines	1-2 cm; paper rich	2-6 cm; paper and plastic rich	<6 cm; mixed
Elemental analysis
C (%)	19.7	34.6	41.6	35.6
H (%)	2.6	4.6	5.6	4.7
N (%)	1.2	1.3	1.3	1.8
S (%)	—	0.2	0.2	—
O (%)	20.3	13.5	27.5	23.2
O + other elements (e.g., Si, Ca, Al, Fe, K, Cl, and P) (%)	76.5	59.3	51.3	57.9
Proximate analysis
Moisture (%)	6.8	6.5	5.0	7.7
Volatile (%)	25.3	40.2	59.9	51.4
Fixed carbon (%)	11.8	7.4	4.7	12.7
Ash (%)	56.2	45.8	30.4	28.1

In the determination of ash content, it was assumed that the residue obtained from thermogravimetric analysis consists of inert materials from the perspective of the pyrolysis, such as CaO, Al₂O₃, SiO₂, and MgO.
