2024
In 2024, the composition of household mixed waste was studied during a one-week monitoring period in September. Households were divided into research groups based on the number of apartments in the property. The research groups were: properties with 1 apartment (divided into two research groups: those that compost and those that are part of the bio-waste collection), properties with 2-4 apartments, properties with 5-19 apartments, and properties with more than 19 apartments (divided into two research groups: rental properties and owner-occupied properties).
