Global warming is major challenge facing mankind globally due to rampant deforestation and emission of greenhouse gases. The pressure on the natural resources has been increasing proportionately with population which needs more food, shelter, textiles, energy and chemicals for day-to-day life. In recent years, research efforts have been made to explore opportunities for utilization of agricultural wastes for enhancement of the circular economy. For instance, considering that Uganda is the largest producer of banana in Africa and the second largest in the world, and that 60% of banana plant is waste, this poses threats and economic opportunities in equal measure in the region. Therefore, efforts to sustainably utilize banana waste are of great importance to reduce their room for decomposition hence greenhouse gas emissions. This review takes stock of the economic opportunities for people in banana growing regions beyond the dining table by exploring sustainable uses of banana wastes as raw materials for fertilizers, textile and bio-fuel. It is here concluded that for realistic conservation of environment, more research is needed on sustainable use of banana waste for briquette production in east Africa which uses cassava starch as binder. Both banana and cassava are widely planted in east Africa but more in Uganda. Use of banana waste and cassava starch in briquette production will ensure reduced global warming, reduced cost of living, creation of new jobs and increased income from the crops.
