Question 1

How is biochar made?

Accepted Answer

Biochar is made by heating organic material like wood, crop waste, or manure in a low-oxygen environment, a process called pyrolysis.

Question 2

How does biochar work?

Accepted Answer

Biochar works by improving soil structure, retaining nutrients and water, and supporting beneficial organisms.

Question 3

How does biochar help in carbon sequestration?

Accepted Answer

Biochar stabilizes carbon for hundreds to thousands of years by locking it in a solid form that won’t decompose or re-enter the atmosphere.

Question 4

How does biochar sequester carbon?

Accepted Answer

Carbon from biomass is captured in a porous solid form during pyrolysis and remains stored long-term when applied to soil.

Question 5

How does biochar remove CO₂ from the air?

Accepted Answer

Biochar locks in carbon from biomass that originally captured CO₂ through photosynthesis, indirectly removing it from the air.

Question 6

How does biochar work and when doesn't it?

Accepted Answer

Biochar works best when activated or inoculated before application. It may not perform well in sterile or already high-carbon soils without additional treatment or integration.

Question 7

How does biochar capture CO₂?

Accepted Answer

It captures carbon by converting biomass into a stable form during pyrolysis, preventing it from returning to the atmosphere.

Question 8

How is biochar prepared?

Accepted Answer

After pyrolysis, biochar is screened, rinsed, and optionally inoculated to maximize effectiveness.

Question 9

How is biochar formed?

Accepted Answer

Biochar is formed through thermal decomposition of organic matter in a low-oxygen environment during pyrolysis.

Question 10

How to use biochar?

Accepted Answer

Biochar can be used in gardens, compost piles, lawns, ponds, livestock bedding, filtration systems, and manure pits. Activation or inoculation before use can enhance performance.
