For the calculation methodology of the ecological calculator we trusted denkstatt Bulgaria<\/strong><\/p>\n<\/div> The calculator automatically calculates the environmental savings from the clothes and\/or shoes left in the specialized containers based on their input characteristics.<\/p>\n Environmental savings consider the assumed reuse and\/or recycling of textiles and shoes. This saves the resources needed to produce new textiles (in the case of re-use) or the inputs needed to produce textiles with different uses (in the case of recycling). The calculator also reflects the greenhouse gas emissions saved (carbon dioxide equivalent) from textiles ending up in landfills and their decomposition.<\/p>\n The quantitative and qualitative characteristics of the provided textile products determine the environmental savings values. They are derived from calculations of several parameters:<\/p>\n The calculator automatically calculates the ecological savings from the textile products left in the containers by the user, based on several key input characteristics:<\/p>\n The calculator automatically calculates the ecological savings from the shoes left in the containers by the user, based on several key input characteristics:<\/p>\n Each shoe category is associated with a specific weight, which is multiplied by two (for a pair) and the number of pairs entered by the user. Each subsequent choice of style, type of shoe and other factors changes the weight of the chosen shoe category. The ratio of the upper part of the shoe to the sole (% sole) also changes according to the user’s subsequent choices, including the density of the selected materials. This follows the logic that bigger shoes (e.g. men’s) have more weight, taller shoes (e.g. boots) have a higher proportion (weight) of their upper part, and shoes with thicker soles (e.g. synthetic rubber or platform shoes) have a heavier bottom part.<\/p>\n<\/div> Clothing, home textiles and toys<\/strong><\/p>\n Shoes<\/strong><\/p>\n\n
