I think I’m slowly becoming a dad who’s way too into lawncare… not sure how I feel about it.

If the goal of SAF is to mitigate fossil emissions, carbon removal can do the same - potentially with greater scalability and lower cost in the near term. I agree that long-term SAF will be essential, but perhaps carbon removal can serve as a bridge? (2/2)

The Sustainable Aviation Fuel (SAF) industry is facing headwinds. I’m hopeful it can overcome them, but I wonder when carbon removal (e.g. biomass burial) might become more attractive (1/2). finance.yahoo.com/news/airline...

The airline industry's dirty secret: Clean jet fuel failures

“Globally, sustainable aviation fuel is expected to increase to 0.7% from 0.3% of aviation fuel this year. But the International Air Transport Assn. expects air travel to climb 6%, causing another jump in emissions.”

Airlines face climate reality check with green jet fuel

U.S. airline efforts to address climate change were eclipsed by those of European airlines last year, but even the Europeans aren't making a dent because of the increase in air travel.

We hope this work sparks greater interest in composting as a robust, scalable Biomass Carbon Removal and Storage (BiCRS) approach—especially for wet, heterogeneous organic waste streams.

--> Levelized costs of CO₂ capture and removal were estimated at $85/tCO₂ and $102/tCO₂, respectively.
--> Significant tCO₂e avoided annually through methane mitigation
--> Nutrient return to soil—a rare benefit among biomass carbon removal pathways

This study evaluates a simple but overlooked climate solution—composting—as a scalable, low-cost pathway for carbon removal. By modifying traditional composting with CO₂ capture technology, we achieved:
--> A relatively high purity stream of biogenic CO₂ in the off-gas

By introducing sodium spiking into the kraft cycle and retrofitting lime kilns with oxy-fuel combustion, we can redirect that CO₂ into a high-purity stream ready for cost-effective carbon capture and storage (CCS) — reducing capture costs by up to 31%. 3/5

🌲 Did you know over 13 million metric tons of biogenic CO₂ are mineralized into carbonates each year in U.S. pulp mills — but then released back into the atmosphere? Our new study shows how we can capture that CO₂ instead — at low cost. 🧵 1/5

Slate Auto, a firm backed in part by Amazon founder Jeff Bezos, is unveiling a low-cost electric truck that can also change into an SUV.

Its starting price point: $20,000 after federal EV incentives.
