Opis:: In the paper issues related to the production and utilisation of waste-derived fuel (alternative fuel) in Poland are presented. Alternative fuel comes from dry residue of waste, mostly municipal, and is treated as a waste. In European Waste Catalogue waste-derived fuel is marked with 191210 code despite their municipal, industrial or mixed origin. The production and utilisation of alternative fuel were analysed with the data from sixteen polish voivodships’ annual reports. The total amount of waste-derived fuel produced in Poland exceeds 3 million tonnes annually. It means there is no balance between the amount of production and possibility of energy recovery in Poland. In 2018 only 1,54 million tons was recovered in R1 recovery process which is only half of the waste-derived fuel produced. In addition, the entire amount of fuel is used in the cement industry. In 2018 in the cement industry 1,46 millions tons of alternative fuel was used. It is estimated that the potential use of alternative fuel by cement plants in Poland is about 1.5-1.8 million tonnes. This means that greater use of alternative fuel in the cement sector is significantly limited. The difference between in the amount of fuel produced and the amount of fuel used for energy recovery in 2018 is around 1.67 million tons. This situation has a significant impact on the economy of waste management in the field of combustible waste production.

Opis:: Processes of mechanical and biological waste treatment (MBT) collected in the mixed waste with selective collection of certain waste fractions, including raw material have a significant influence on reaching environmental effect connected with mitigation the amount of waste directing to disposal by landfilling. A regional installation for municipal waste treatment could be a mechanical and biological municipal waste treatment installation, with proper throughput (production capacity) adapted to the quantity of waste production by inhabitants of specific region with an assumed population of 120,000 inhabitants. An estimation of mechanical stages of the MBT installation is a relatively effortless issue to perform. In contrast, an estimation of the production capacity for a biological installation requires wide analysis of the quantity of waste production collected in the mixed waste, including the morphology composition of the waste and formulation of quantity and quality forecasts of waste streams directing to the biological stage of installation. Production capacity of mechanical stage of the MBT is the result of waste production quantity collected in the mixed waste from inhabitants in the specific region. On the other hand, production capacity of biological stage of the MBT should be adapted to the treatment of waste with the code 19 12 12, arisen after the process of the mechanical treatment in the MBT. In practice, there is often supposed that the throughput of biological stage of the MBT should be formed at the level of the half throughput designed for the mechanical stage. The attempt of rates estimation, which would let forecast the quantity of waste stream directing to the biological stage of the MBT, was conducted as well as the analysis of the stream directing to the biological processed waste (called ‘stabilizat’) production and the stream directing to the Refuse Derived Fuel production (RDF). The forecast of waste production divided into morphological fractions was performed for 2013 and 2020. The analyses covered municipal waste stream producing by stipulated region with an assumed population of 120 000 inhabitants, collected in the mixed waste divided into the categories of: the city over 50 000 inhabitants, the city under 50 000 inhabitants, countrysides, the region of Lesser Poland Voivodeship with 30% of people living in the large city, 20% for small city and 50% for countryside. According to performed estimations, it could be ascertained that the 19 12 12 fraction, emerging in the mechanical segregation process, directing to the biological processed waste (‘stabilizat’) production provide: 51% of mixed waste produced in 2013, 61% in 2020 for the large city region, 61% and 70% for the small city region, 63% and 71% for countrysides. The waste mass produced in the mechanical segregation process with the purpose of biological drying and further to the Refuse Derived Fuel production is slightly higher, including inflammable fraction assigned to sieves with the diameter over 80 mm. These percentages could be legitimated as essential for production capacity of the biological stage of the MBT forecasting. In the period from 2013 to 2020, the percentage share of 19 12 12 fraction waste is increasing due to decreasing mixed municipal (residual) waste production. Estimated in this paper, increase percentages of waste directed to the biological treatment is mainly due to the assumed and the gradual increase of selective collection municipal waste ‘at the source’.
