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

Scenario numberScenario descriptionDetermining the pattern – variant IDetermining the pattern – variant II
Scenario 1the 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=MrpmpgMwREAL×100% where:P – level of preparation for re-use and recycling of municipal waste, %,Mrpmpg – total mass of paper, metal, plastic and glass waste prepared for re-use and recycling, Mg,MwREAL – total mass of generated (collected) municipal waste, Mg p=MrpmpgMwCSO×100% where:P – level of preparation for re-use and recycling of municipal waste, %,Mrpmpg – total mass of paper, metal, plastic and glass waste prepared for re-use and recycling, Mg,MwCSO – total mass of generated municipal waste, Mg
Scenario 2the 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=Mrpmpg+BIOMwREAL×100% where:P – level of preparation for re-use and recycling of municipal waste,%, Mrpmpg+BIOrec – total weight of paper, metal, plastic, glass and recycled bio-waste, Mg,MwREAL – total mass of generated (collected) municipal waste, Mg p=Mrpmpg+BIOMwCSO×100% where:P – level of preparation for re-use and recycling of municipal waste, %,Mrpmpg+BIOrec – total weight of paper, metal, plastic, glass and recycled bio-waste, Mg,MwCSO – total mass of generated municipal waste, Mg
Scenario 3the 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=Mrsel(pmpg+BIO)MwREAL×100% where:P – level of preparation for re-use and recycling of municipal waste, %,Mrsel(pmpg+BIO) – total mass of separately collected waste paper, metals, plastics, recycled glass and bio-waste, Mg,MwREAL – total mass of generated (collected) municipal waste, Mg p=Mrsel(pmpg+BIO)MwCSO×100% where:P – the level of preparation for re-use and recycling of municipal waste, expressed in %,Mrsel(pmpg+BIO) – total mass of separately collected waste paper, metals, plastics, recycled glass and bio-waste, Mg,MwCSO – total mass of generated municipal waste, Mg
