Team

Operators who've built and run biochar and bio-oil projects.

Not just advised on them. The Tanren leadership team has been on-site through commissioning, on the phone with regulators, and on the ground with farmers.

Rohit Nagargoje, CEO

Rohit Nagargoje

CEO

Rohit has spent his career at the intersection of engineering and commercial strategy in the carbon removal and biofuel space, having co-founded and helped scale a biochar and biofuel venture from early pilots to commercial operations. His background traces to DTU (Technical University of Denmark), including research on membrane technology at Aquaporin. At Tanren, he leads strategy and client partnerships, bringing a full-chain view to every engagement.

Bobby Choudhary, Director, Operations

Bobby Choudhary

Director, Operations

Bobby built his career on the plant floor — running test centers and commissioning pyrolysis and biochar units where the engineering meets reality. He's spent years in the gap between a design on paper and a plant that actually holds up day after day. At Tanren, he leads project execution and operations, the phase most projects underestimate.

Naman Gupta, Director, Engineering & New Tech

Naman Gupta

Director, Engineering & New Tech

Naman comes from process and equipment engineering, having worked hands-on with pyrolysis system design, sizing, and technology selection. He's the one who tests a new technology against its actual pilot-scale numbers before it gets anywhere near a commercial proposal. At Tanren, he leads engineering and new technology evaluation.

Priyanka Sathe, Director, Biochar Science & Carbon Quantification

Priyanka Sathe

Director, Biochar Science & Carbon Quantification

Priyanka holds a PhD in Biotechnology from the Institute of Chemical Technology and a Master's from Tamil Nadu Agricultural University, with earlier research at the National Research Centre for Grapes. Over more than a decade, she has led large-scale field programs across diverse geographies — biochar ageing and stability studies, carbon fraction quantification, and field sampling frameworks built to hold up under MRV scrutiny. She authored the Return on Residue (RoR) framework linking biomass regeneration to soil carbon outcomes. At Tanren, she directs biochar science and carbon quantification, translating field-level complexity into verifiable, auditable carbon results.

Srikanth Vishwanath, Director - Carbon Markets & Certification

Srikanth Vishwanath

Director - Carbon Markets & Certification

Srikanth has spent his career at the intersection of carbon markets and certification — leading due diligence on carbon removal transactions, structuring offtake agreements, and driving certification under standards including Puro.earth, the Global Biochar C-Sink, and ISCC EU. He's also designed MRV systems end-to-end, from feedstock sourcing through to verified output. At Tanren, he leads carbon markets, certification, and MRV, making sure every tonne claimed is a tonne that holds up to scrutiny.

We're hiring

Engineers, project managers, carbon specialists.

If you've built, commissioned or run biochar / bio-oil plants — or want to — we want to talk.
