“ECOSTP” by ECOSTP Technologies, image/information source: ECOSTP
EcoStp, also known as ECOSTP, is a biomimicry-based sewage treatment technology developed by ECOSTP Technologies in India around 2017-2018. It replicates the multi-chambered digestive process of a cow’s stomach to treat wastewater without electricity, chemicals, or mechanical parts, making it a zero-energy, low-maintenance solution for urban sanitation.madeforplanet+2
Biomimetic Design
The system mimics the rumen microbiome in ruminants like cows, where four stomach compartments host anaerobic microbes that progressively break down complex organic waste. ECOSTP uses underground chambers to replicate this: initial stages hydrolyze solids, followed by acidogenesis, acetogenesis, and methanogenesis for biogas production and purification. A final wetland-inspired filtration absorbs remaining nutrients, yielding water safe for flushing or irrigation.ecostp+2
Core Features
- Zero-Energy Operation: Relies solely on gravity and natural microbial action, slashing costs by 70-90% compared to conventional STPs like SBR or MBBR.habitat+1
- Scalable Modularity: Suited for apartments, industries, hospitals; treats 10-5000 m³/day silently with no odor.[ecostp]
- Advanced R&D: Developing “PEB” (Phenol-Eating Bacteria) for persistent pollutants like phenols.[youtube][ecostp]
| Chamber | Cow Stomach Analogy | Treatment Role |
|---|---|---|
| 1 | Rumen | Hydrolysis of solids [asknature] |
| 2-3 | Reticulum/Omassum | Fermentation to acids/gases [ecostp] |
| 4 | Abomasum | Nutrient uptake/polishing [madeforplanet] |
Recognition and Impact
Selected for the 2018-19 Biomimicry Launchpad accelerator alongside global finalists, EcoStp earned investment from Habitat for Humanity and serves 200+ clients across India. Founded by Tharun Kumar, it advances UN SDG 6 by decentralizing sanitation in high-cost regions.globalsociety+2
