Recycling rates [%] in the analyzed scenarios in two variants

Description		Large municipalities Recycling rate [%]	Medium municipalities Recycling rate [%]	Small municipalities Recycling rate [%]	Average value of the recycling rate [%]
Scenario number	Variant Number	Large municipalities Recycling rate [%]	Medium municipalities Recycling rate [%]	Small municipalities Recycling rate [%]	Average value of the recycling rate [%]
Scenario 1	Variant I	12.96	15.08	12.22	13.42	16.65
	Variant II	18.48	21.20	19.94	19.87	16.65
Scenario 2	Variant I	21.74	17.37	16.52	16.52	22.95
	Variant II	31.03	24.12	26.90	26.90	22.95

	Variant II	42.72	47.99	29.81	29.81	33.55

Summary of scenarios and determination of the patterns of the recycling rate in the developed variants

Scenario number	Scenario description	Determining the pattern – variant I	Determining the pattern – variant II
Scenario 1	the recycling rate is calculated as the ratio of the weight of paper, metal, plastic and glass (PMPG) prepared for re-use and recycling to the weight of total municipal waste generated	$p = \frac{M r_{p m p g}}{M w_{R E A L}} \times 100 %$ where:P – level of preparation for re-use and recycling of municipal waste, %,Mr_pmpg – total mass of paper, metal, plastic and glass waste prepared for re-use and recycling, Mg,Mw_REAL – total mass of generated (collected) municipal waste, Mg	$p = \frac{M r_{p m p g}}{M w_{C S O}} \times 100 %$ where:P – level of preparation for re-use and recycling of municipal waste, %,Mr_pmpg – total mass of paper, metal, plastic and glass waste prepared for re-use and recycling, Mg,Mw_CSO – total mass of generated municipal waste, Mg
Scenario 2	the recycling rate is calculated as the ratio of the weight of paper, metal, plastic and glass waste prepared for re-use and recycling, and bio-waste transferred to the recycling process (input into the recycling process) to the total weight of municipal waste generated	$p = \frac{M r_{p m p g + B I O}}{M w_{R E A L}} \times 100 %$ where:P – level of preparation for re-use and recycling of municipal waste,%, Mr_pmpg+BIOrec – total weight of paper, metal, plastic, glass and recycled bio-waste, Mg,Mw_REAL – total mass of generated (collected) municipal waste, Mg	$p = \frac{M r_{p m p g + B I O}}{M w_{C S O}} \times 100 %$ where:P – level of preparation for re-use and recycling of municipal waste, %,Mr_pmpg+BIOrec – total weight of paper, metal, plastic, glass and recycled bio-waste, Mg,Mw_CSO – total mass of generated municipal waste, Mg
Scenario 3	the recycling rate is calculated as the ratio of the weight of paper, metal, plastic and glass waste and bio-waste collected and collected selectively in municipal waste management systems to the total weight of municipal waste generated	$p = \frac{M r_{s e l (p m p g + B I O)}}{M w_{R E A L}} \times 100 %$ where:P – level of preparation for re-use and recycling of municipal waste, %,Mr_{sel(pmpg+BIO)} – total mass of separately collected waste paper, metals, plastics, recycled glass and bio-waste, Mg,Mw_REAL – total mass of generated (collected) municipal waste, Mg	$p = \frac{M r_{s e l (p m p g + B I O)}}{M w_{C S O}} \times 100 %$ where:P – the level of preparation for re-use and recycling of municipal waste, expressed in %,Mr_{sel(pmpg+BIO)} – total mass of separately collected waste paper, metals, plastics, recycled glass and bio-waste, Mg,Mw_CSO – total mass of generated municipal waste, Mg
