Closing the Loop Between Cities and Farms
A deep-tech innovation team on a mission to redesign urban sanitation into a distributed agricultural resource network.
Who We Are
LignoGold Terra Solutions is a deep-tech innovation team closing the loop between urban infrastructure and sustainable agriculture. We intercept wastewater assets at the source, transforming high-BOD/COD waste into high-value organo-mineral fertilizers — turning a costly disposal problem into a profitable resource recovery operation.
Founded and MSME-registered in Chennai, Tamil Nadu, we are building India's first commercial-scale decentralized nutrient recovery infrastructure — one Ligno-Pod at a time.
“The future of sanitation isn't treating waste—it's recovering value before it becomes waste.”
— Manjueesa Arumugam Yadav, Founder & CEO
Three Pillars
Mission
Close the nutrient loop between cities and farms — transforming urban waste streams into agricultural abundance.
Technology
Modular, in-situ biomineralization systems that require zero manual intervention and integrate into existing infrastructure.
Impact
Carbon sequestration, food security, and nutrient sovereignty — measured, verified, and delivered to our partners.
Dual-Engine Revenue
Hardware-as-a-Service (HaaS)
Commercial facilities pay a predictable monthly subscription per urinal pod — zero CapEx hardware deployment, automated "Seal-and-Swap" maintenance, guaranteed scale-free pipes and zero odors.
Premium Fertilizer Sales
Nutrient-saturated cores are collected, processed, and sold as high-value, slow-release phosphorus and ammonia-enriched organic inputs to FPOs and distributors.
