Lifecycle Assessment of the fruit and vegetable waste treatment technologies in Uganda.
Abstract
The generation of Fruit and Vegetable waste is a growing concern in Uganda, with increasing demand for sustainable waste management solutions. Because of its high biodegradability, FVW causes environmental issues, as well as a loss of valuable biomass and an economic expense to businesses. This study assessed the environmental impact of different waste treatment technologies in Uganda through a Life Cycle Assessment (LCA) approach. The study collected the emissions associated with the different waste treatment technologies, including composting, anaerobic digestion, landfill, vermicomposting and black soldier fly composting. The study then established the impact of these on the different impact categories which included global warming, eutrophication, human toxicity, and acidification. The results showed that anaerobic digestion performed best in terms of acidification potential, human toxicity potential, and eutrophication potential. Vermicomposting however performed best in terms of global warming potential. The study also included modifications needed for the treatment technologies to ensure less impact on the environment. However, more research is needed on how the modifications of the different technologies reduce the environmental impact. The findings of this study provide valuable information for decision-makers, waste management practitioners, and stakeholders in Uganda to promote environmentally sustainable waste management practices. The results of this study highlight the importance of implementing comprehensive waste management strategies that incorporate environmentally sustainable waste treatment technologies to reduce the impact of FVW on the environment and public health in Uganda.
