## 3 Results  
The tests were performed in two series. Series 1 refers to the preconsumer waste. Series 2 refers to the postconsumer waste. During each series, the tests were performed for three maximum process temperatures: 400 \({}^{\circ}\)C, 425 \({}^{\circ}\)C, and 450 \({}^{\circ}\)C. Also, three gas samples were collected during each test: at the beginning of the process, during the process, when the decomposition was the most rapid, and

The moment of most rapid mass loss in the sample was determined based on the thermogravimetric study [9]. The solid and liquid products were weighed after the process, after the reactor was cooled to room temperature. The mass of the generated gases was calculated based on the measurements. The mass diagrams for the products obtained from series 1 and 2 are presented in Figure 3.  
The amount of generated gases increased with temperature both during series 1 and 2. At the lowest temperatures, the amount of generated gases was very small. The process performed at lower temperatures is most likely to generate more oil and solid products. This may also suggest that at lower temperatures, not all the material was decomposed. Higher temperatures generate more gases and less oil and solid products. Slightly more gases and liquid fraction have been generated during the pyrolysis of the preconsumer waste, while the postconsumer waste generated more solid products (aluminum and char). However, those differences were almost negligible. Therefore, there was almost no difference between the yields and the quality of the products generated during the pyrolysis of pre- and postconsumer waste. It seems that the trace amounts of pharmaceutical products left on the used blisters did not affect the process and the quality of the products. The results of the gas analysis of two materials at 400 \({}^{\circ}\)C, 425 \({}^{\circ}\)C, and 450 \({}^{\circ}\)C are presented in Tables 2-7. For series 1 (preconsumer waste), the concentration of hydrocarbons increased with the temperature. The total content of hydrocarbons at max. temperature 400 \({}^{\circ}\)C was 19.5%, 25.9% at 425\({}^{\circ}\)C, and 26.2% at 450\({}^{\circ}\)C. The oxygen content at the beginning of the process was neglectable. Nitrogen content in the gases decreases during the process. The amount of CO in the gases was higher at higher temperatures. Based on the results it can be concluded that the quality of the gas as a fuel increases with the process temperature. Similarly to what happened in series 1, in series 2 the content of hydrocarbons increased with the temperature. The concentration at max. temperature 400 \({}^{\circ}\)C was 16.4%, 23% at 425 \({}^{\circ}\)C, and 25.6% at 450 \({}^{\circ}\)C. The nitrogen content decreased during the process. For the mixed waste pharmaceutical blisters, the amount of generated CO at different max. temperatures was almost constant, while the CO\({}_{2}\) content increased. This may have been caused by the fact that the material contained trace amounts of pharmaceutical products that may react more quickly than plastic. Another possible explanation is that some oxygen may have penetrated into the gas cooler and reacted with other gas components. The diagrams showing the changes in the contents of the selected gas compounds are presented in Figures 4-6. Tests PF0 and PB0 were performed at a maximum temperature of 400 \({}^{\circ}\)C. Tests PF1 and PB1 were performed at the max. temperature 425 \({}^{\circ}\)C, and tests PF2 and PB2 were performed at the max. temperature 450 \({}^{\circ}\)C.
