What is Biochar? Uses, Benefits and Why It Matters

Biochar may sound new, but it’s actually an ancient solution getting a modern upgrade.

Originally used thousands of years ago to improve soil in places like the Amazon, biochar is now gaining attention as a tool for carbon sequestration and sustainable waste management.

So what is it?

Biochar is created by heating organic material—like yard waste—in a low-oxygen environment. Instead of decomposing and releasing emissions, the carbon is converted into a stable, solid form.

That stability is what makes it valuable.

In agriculture, biochar is especially effective in sandy soils like those found throughout Florida. It helps retain water and nutrients, which can:

• Reduce irrigation needs
• Lower fertilizer use
• Improve soil health over time

That also means less nutrient runoff into waterways—helping address issues like algal blooms and water quality degradation.

Beyond agriculture, biochar has growing applications in:

• Building materials (as a carbon-storing additive)
• Water filtration systems
• Stormwater management
• Environmental remediation

So why isn’t it widely used already?

Two main barriers: limited supply and cost.

High-quality biochar production is still scaling in the U.S., which keeps prices relatively high and limits adoption. Expanding supply—especially from waste streams like yard debris—is key to unlocking its full potential.
