Abstract:

The challenge of waste management should be finding a way not to produce waste; and to rethink waste management to a point where the processes, methods, techniques and solutions to the problem of waste do not themselves produce waste. The circular economy is arguably the closest solution we can get to a future without waste. Solid and liquid waste pose significant problems and challenges in disposal and both negatively impact the ecological systems critical to the wellbeing of the environment and humanity’s survival. We must harness the power of science to be able to find solutions firstly to not producing waste and secondly to handle the already produced waste in a manner that can benefit the environment and help fix the environment. There must be a shift to regard waste as a resource, to promote a waste hierarchy of recovery of waste, where prevention, reduction, reuse, recycling and composting are of primary consideration followed by other means of recovery such as energy recovery and lastly disposal. This will translate to the development and promotion of public health by observing solid waste safeguards that uphold key social and health determinants. It is also important to emphasize that proper waste management is crucial for maintaining hygiene and for economic and social reasons, as waste can serve as a source of low-cost raw materials for bio-energy and valuable bio-products with high potential.
