- Accompanying Measures / Technical Trainings Estimation of Generated Waste Amounts 1.a) commercial activities by the use of specific parameters 1. Creation of specific parameters for inhabitants public services (hospitals, schools, kindergartens) commercial activities (offices, restaurants, cinemas, department stores, supermarkets, a.o.) 2. Calculation of the waste amounts according to the real figures of the inhabitants or specific activities in the municipality Calculation on the basis of the number of inhabitants or

- Accompanying Measures / Technical Trainings Estimation of Generated Waste Amounts Long term forecast: Waste from inhabitants Waste from tourists Waste from public services (hospitals, schools, kindergartens) Waste from streetcleaning and markets Waste from commercial activities (offices, restaurants, cinemas, department stores, supermarkets, etc.)
- Accompanying Measures / Technical Trainings Estimation of Generated Waste Amounts Long term forecast and waste disposal costs: Waste from: inhabitants tourists => paid via waste service fee => paid via contracts with hotels and service fee => paid via contracts or service fee public services streetcleaning and markets => paid via waste service fee commercial activities => paid via contracts or service fee
- Accompanying Measures / Technical Trainings Analysis of Waste Composition How to get figures on Waste Composition?
- Accompanying Measures / Technical Trainings Analysis of Waste Composition What it is good for? to know material composition (recyclable components, harmful components) to assess/be aware of treatment/safety needs to understand where prevention should/can be exercised to assess feasibility and efficient ways of separate collection to determine other management measures and monitor effectiveness to get note on changes/trends in the waste generation to support waste estimations and/or verify available data to educate people
- Accompanying Measures / Technical Trainings Waste prognosis meaning and importance What it is good for? to know future waste amounts generated to plan waste collection and waste treatment capacities to understand the effects of waste management measures to assess feasibility and efficient ways of separate collection to get note on changes/trends in the waste generation to educate people
