Sustainable food waste management model for Bangladesh

2021

Excessive food waste (nearly 1.3 billion tons per annum) has exacerbated the world hunger crisis. This comprehensive review focuses on the food waste scenario, adverse effects, food waste management, existing waste management policies, and regulations in Bangladesh. Municipalities and urban centers generate 3.78 million tons of waste each year (15.96% of total food waste). This study utilized the national database to analyze food waste generation and projected growth by the year 2050. Yearly an estimated 17215.2 thousand acres of land and a significant amount of natural resources (water, energy) are being used to produce 23691.15 thousand tons of wasted food (45% of total food production). This study critically analyzed the waste management policy gap of Bangladesh and clearly identified each stage of the food loss production supply chain. The study assessed that yearly 481.6 MW energy could be generated from food waste. Focusing on effective policy and sustainability, a national food waste management model has been proposed for Bangladesh in compliance with sustainable development goals 12.3.1 global food loss. Food accumulates 16.7% to 20% of the world economy; therefore, any measures taken to reduce the food waste will be economically beneficial and environmentally sustainable.
