**Appendix A**

The share of biowaste on the total composition of RES can vary greatly depending on different factors such as economic and social development of the country, legislation, or geographical location. It has to be highlighted that accurate and reliable data on waste composition is a critical input for environmental assessment calculations [31]. Consequently, a great deal of attention has to be paid when assessing these data. In this paper, the composition of RES for the Czech Republic obtained using tool JUSTINE was used. Such values would also be typical for other similarly developed countries in Europe.


**Table A1.** RES composition for the Czech Republic obtained using tool JUSTINE [28] for 2016.

**Table A2.** The fuel mix for the power and heat industry in the Czech Republic (Slivka, 2011) [32].
