America's Carbon Capture Quest: Absorbing 2 Billion Tons from the Atmosphere

As climate change intensifies, finding effective ways to remove carbon dioxide (CO₂) from the atmosphere is essential.

While many startups focus on complex, industrial methods for carbon capture, a new nature-based approach is emerging as a potential game-changer: biochar.

By turning agricultural waste into biochar—a carbon-rich material that improves soil health and locks away carbon for centuries—companies like Applied Carbon are pioneering a method that could transform the fight against climate change.

Understanding Biochar and Its Role in Carbon Capture

Biochar is created through a process called pyrolysis, where organic materials are partially burned in an oxygen-free environment.

This process creates a stable carbon structure that can be used as a soil amendment. “Biochar offers a powerful solution for carbon dioxide removal that outperforms traditional methods, such as tree planting,” says Jason Aramburu, CEO of Applied Carbon.

Unlike trees, which take decades to mature, biochar can be produced quickly and applied directly to farmland, making it a readily available option for carbon storage.

Biochar’s potential as a carbon dioxide removal tool is vast. According to Aramburu, it could sequester up to two billion metric tons of carbon each year if scaled up effectively.

This ancient method, which has been used for more than 2,000 years in South America, is gaining renewed attention for its dual benefits: improving soil health and combating climate change.

By enhancing nutrient retention, reducing the need for fertilizers, and increasing crop productivity, biochar is an attractive option for farmers aiming to boost yields while adopting environmentally friendly practices.

The Challenges and Innovations in Biochar Production

Despite its clear benefits, producing biochar presents several challenges. Traditionally, most biochar has been made using wood waste at centralized biomass plants, often far from farming regions.

This distance increases transportation costs and decreases the overall carbon benefits of biochar production.

Furthermore, agricultural waste like corn stover and wheat straw, while abundant, is difficult to process due to its low density and high silica content.

To address these challenges, Aramburu and his co-founder, Morgan Williams, decided to rethink the production process by bringing the biochar production facility directly to the farm.

Their solution involves a mobile pyrolysis machine that can be attached to existing farm equipment.

This allows farmers to convert agricultural byproducts into biochar on-site, significantly reducing transportation costs and energy usage.

Not only does this innovation streamline logistics, but it also enhances carbon tracking, making the entire process more sustainable.

Expanding Biochar Production Across the Southern United States

Applied Carbon recently secured a $21.5 million Series A funding round, led by TO VC, to accelerate the development and deployment of its biochar production technology.

With this funding, the company plans to expand its operations across Texas, Oklahoma, Arkansas, and Louisiana.

The goal of Applied Carbon is to move from prototype models to initial production-ready machines, creating a range of biochar machines that can help farmers produce and use biochar efficiently.

In addition to technological advancements, support from organizations like the USDA is crucial in promoting the adoption of biochar.

With new financial incentives available for farmers who incorporate biochar into their practices, there is potential for widespread adoption.

Aramburu emphasizes that this can serve as a groundbreaking innovation for biochar, making it a more accessible and attractive option for farmers across the United States.

Biochar’s Future in Sustainable Agriculture

Transitioning to sustainable agriculture is key in the fight against climate change, and biochar offers a unique way to increase agricultural productivity while removing carbon from the atmosphere.

Companies like Applied Carbon are tackling the logistical challenges of biochar production by leveraging existing agricultural infrastructure to create accessible solutions for carbon sequestration.

With growing financial support and backing, biochar’s potential to improve soil health and enhance carbon capture is gaining momentum.

In the words of Sanusha S., “America has begun to absorb the atmosphere: It’s swallowing 2 billion tons from the ground.” This initiative not only promises to change the landscape of agriculture but also offers a viable path forward in the broader battle against climate change.
