Drivers

Wastewater Treatment and Energy Generation

One of the most compelling reasons for adopting Microbial Fuel Cells (MFCs) is their ability to simultaneously address two pressing challenges: wastewater treatment and renewable energy generation. In India, where rapid urbanization and industrialization have led to increased wastewater production, MFCs offer a sustainable solution that not only treats wastewater but also recovers energy in the process.

The Muttathara Sewage Treatment Plant (STP) in Thiruvananthapuram, Kerala, exemplifies this dual benefit. In its second phase of development, the plant inaugurated an advanced omni processor system at an estimated cost of ₹36 crore. This state-of-the-art waste treatment system processes treated sludge to generate electricity, clean water, and by-products like ash for fertilizers or construction use. Notably, Muttathara becomes one of only five locations globally to implement such a system.

The omni processor functions by incinerating the solid portion of separated waste to produce energy and condensing the water vapor into potable water. This approach not only reduces pathogens but also recovers valuable resources from wastewater, biosolids, and other waste materials. The initiative is a collaboration among the Thiruvananthapuram civic body, Kerala Water Authority (KWA), and Ankur Scientific Private Ltd, and is funded by the Bill and Melinda Gates Foundation with technical support from Ankur Scientific.
