Mangrove Systems Acquires Grain Ecosystem, Strengthening Its Global Biochar MRV Platform

TORONTO, ON — April 16, 2026 — Mangrove Systems (Mangrove) has acquired select operating assets from Grain Ecosystem (Grain), a digital biochar project development platform focused on the North American biochar sector. The transaction brings Grain’s customer base of biochar operators onto Mangrove’s compliance and monitoring, reporting, and verification (MRV) platform.

The acquisition reflects Mangrove’s continued investment in the biochar and carbon dioxide removal (CDR) sector. With a portfolio of operators, Grain played a foundational role in building the North American market for biochar. That work makes the transaction a strong strategic fit for Mangrove, deepening its commitment to the biochar sector and strengthening its position as the compliance platform of choice for carbon removal operators at scale.

The combined customer base represents a significant share of the operational global biochar market today.

Letourneau, Co-Founder & CEO of Grain Ecosystem. “Grain has built a strong platform and market presence in the biochar sector, and we believe Mangrove is well positioned to carry that work forward.

“Annie Nichols, General Manager of Biochar at Mangrove Systems,” said Annie Nichols, General Manager of Biochar at Mangrove Systems. “Biochar is one of the most promising and fastest-growing segments of the carbon removal market, and this acquisition deepens our commitment to it.
