Sustainability of animal origin food waste in Serbia

This research analysed attitudes related to food waste sustainability and estimated amounts of animal origin food waste and food packaging waste discarded in Serbia. The field survey covered 494 respondents from Belgrade, Serbia. Results present their degree of agreement with nine selected food waste sustainability statements and their reported quantities of discarded animal origin food waste and food packaging waste. Our study showed respondents have a higher rate of agreement related to the negative social and environmental dimensions of food waste, while they have no opinions associated with the economic dimensions. Regarding animal origin food waste quantities, it is estimated that households dispose around 200 g of waste every week (11.3 kg per year) and slightly under 30 different pieces of food packaging. On an annual basis, 7,234 tons of CO2 emissions can be associated with animal origin food waste and 706.4 tons with food packaging waste in Serbia

Applying life cycle thinking at an early design stage can help engineers to deliver sustainable systems by design. To demonstrate how this can be carried out at a practical level, this paper proposes a simplified methodology for integrating life cycle considerations into process design. Combining flowsheeting and life cycle assessment, it shows how environmental 'hotspots' can be identified and translated into key design targets to improve the sustainability of a system from 'cradle to grave'. The method is applied to a carbon capture and utilisation system using waste CO2 to produce synthetic diesel in a Fischer-Tropsch process. Although the system is energy intensive, applying life cycle thinking helps to make synthetic diesel competitive not only with fossil but also with biodiesel in terms of the climate change impact
