Recycling of organic wastes using locally isolated lignocellulolytic strains and sustainable technology

The magnitude and nature of the waste generated across different borders have prompted the need for an appraisal of the conventional method of waste collection and the landﬁll or incineration that are unsustainable due to their high cost and impact on the environment and public health. This study fo...
