Carbon removal and critical minerals don't seem related, but they face strikingly similar challenges.
Both are hard-tech with long timelines. Both compete with cheaper but riskier alternatives. Both need procurement commitments, strategic reserves, and supply chain coordination to scale.

Researchers built a new DAC sorbent from upcycled wood waste. The clever bit: sunlight releases the captured CO₂.
Lignin in the material enables photothermal heating — no external energy for regeneration. That matters because sorbent regeneration is DAC's biggest cost.
Early-stage, but cheap feedstock + solar regen could reshape DAC economics.

A new CDR pathway is organizing: take waste wood, crop residues, or biomass and store it underground before it decomposes.
Direct Storage of Biomass Coalition launched under the Carbon Business Council. 17 members including Graphyte, Carba, Puro.Earth, Isometric, Vaulted Deep.
Low-tech, scalable, built on existing supply chains.

🌍 From India: Farmers in Darjeeling spread basalt dust on rice paddies. Each verified tonne of CO₂ removed becomes a credit worth $150–600.
50 CDR projects registered. 214,000 verified removal credits. Startup Alt Carbon sources basalt from quarry waste, gives it to farmers free.
Could India become a low-cost CDR powerhouse?

Google signed a deal with AMP to remove 200,000 tons of CO₂ by 2030 — by turning landfill waste into biochar.
AMP uses AI sorting to recover organics from municipal waste, then converts them to stable carbon. First deploy: Virginia's largest recycling project.
Double win: carbon removal + methane avoidance.

📰 CDR Daily Digest — March 17, 2026
Big day for carbon removal:
• Big Tech CDR purchases up 181% — 68.4M credits in 2025
• Canada becomes first government to buy CDR credits ($10M CAD)
• Sweden commits $34M to negative emissions scaling
• Verde turns roads into carbon sinks with biochar asphalt
• First global CDR credit rulebook being drafted
https://www.captaindrawdown.com/posts/2026-03-17-cdr-daily-digest/
The first global rulebook for carbon removal credits is being drafted right now.
The IPCC found that large-scale carbon dioxide removal is needed for every pathway to net-zero by 2050. Now the rules for how we verify, price, and trade permanent removal are being written.
This will shape the entire CDR market for decades.

🇸🇪 Sweden just launched two new calls for negative emissions projects under its Industriklivet program.
• $32M (SEK 300M) for scaling and commercialization
• $1.6M (SEK 15M) for research
Covers bio-CCS, DAC, and geological storage across the full value chain. Applications open until April 29.
Nordic countries keep quietly leading on CDR policy.

What if every road could store carbon?
Verde just secured 38,500 tons/year of engineered biochar supply for its BioAsphalt™ technology. They already earned the world's first carbon removal credits from an asphalt application, verified by Puro.earth.
Infrastructure-based CDR is quietly becoming real.

🇨🇦 Canada just became the first national government to launch a dedicated carbon removal procurement program.
$10M CAD for federal departments to buy CDR credits — covering DAC, BECCS, biochar, and enhanced mineralization. All projects must be in Canada.
This is the demand signal the industry needs.
