It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste.
Valorisation of food waste offers an economical and environmental opportunity, which can reduce the problems of its conventional disposal. Food wastes have been demonstrated to be valuable bioresources that can be utilised to obtain a number of useful products, including biofertilizers , bioplastics , biofuels , chemicals, and nutraceuticals.
