Generation of food waste is a challenging problem for reaching sustainable development goals. Effective management of food waste is needed for efficient use of natural resources. This thesis aims at evaluating feasibility, perspectives and environmental impact of separate food waste collection in Lithuanian households. A Food waste management system should be based on waste management hierarchy. First of all, prevention should be implemented, followed by reuse, recycling, energy recovery and only in the end food waste disposal. Moreover, it is important to use an holistic approach combining environmental, social and economic benefits when implementing food waste management solutions. In this paper results from a study on food waste from 105 households are presented. It was found that the average annual food waste in Lithuania is 59,8 kg per capita, of which 30,1% could be avoided. Furthermore, different household food waste management systems in Lithuania are discussed. The impact of different food waste management systems on acidification, eutrophication, global warming and photooxidant formation is analysed using the life cycle assessment. |
