11 Uncontrolled burning of waste
 35,000 inhabitants 2, ,000 inhabitants  2,000 inhabitants Part of total population 46.1% 22.1% 31.8 % Percentage of households not connected 20% 80% Generation af waste, kg/person/year 240 180 60 Generation af combustible waste, kg/person/year 81 55 20 Total amount of combustible waste of households not connected, t 25,600 8,300 18,500 The Ministry of Environment of the Republic of Lithuania

12 Improvement of the inventory
Investigation of the extent of uncontrolled burning of waste products Obtain more exact information on flue gas treatment used for production of cement and waste incineration (emission factors evt. confirmed by measurements) Improvement quality of stastitical data for all activities Strengthening the information management capacities The Ministry of Environment of the Republic of Lithuania

13 The Ministry of Environment of the Republic of Lithuania
Measures Reduction of uncontrolled burning of waste products Collection of waste Information campaigns Improved landfill practice Reduced use of chlorinated plastics and other chlorinated products Increased air pollution control for power generation, cement production and waste incineration (if a need is confirmed by further investigation) The Ministry of Environment of the Republic of Lithuania
