Coffee is one of the most traded commodities in the world, production of which requires large volumes of water. It is also a highly polluting industry as 50%-55% of the total water used is discharged as effluents. The wastewater is typically generated from the pulping process and mechanical mucilage removers and contains high concentrations of fermenting sugar, TSS ( Total Suspended Solids ), alkaloids, tannin and polyphenolics – which makes the degradation of organic material very difficult.
In the last few decades, the environmental threats caused by discharge of ineffectively treated coffee effluents have increased exponentially. People residing in vicinity of coffee industries, who consume the polluted water, suffer from various diseases such as spinning sensation, eye, ear and skin irritation, stomach pain, nausea and severe breathing problems. Furthermore, the effluents are also very harmful for the aquatic and wildlife. Hence, there is an immediate need to curb this problem with innovative, viable and eco-friendly techniques.
