A review of post-consumption food waste management and its potentials for biofuel production

The global world production of food waste is expected to increase by 33% within the next decade. The current annual food waste stands at around 1.6 billion tonnes, which is worth around $ 1.2 trillion loss. Out of this, nearly 50%–60% comes from post-consumption waste (leftover). Besides, food waste...
