The majority of activated carbon production is exported to developed countries in North America and Europe, where it is used in environmental and processing applications. The activated carbon marketplace is dominated by a relatively small number of international companies that have both production and marketing capabilities.
Over the past few years, the developed countries have been enacting new regulations requiring the removal of trace mercury from industrial emissions, principally impacting the coal-based electric power industries in North America and Europe. This has created an additional market for specialized powdered activated carbons that serve to capture mercury from the flue gases of power plants.
Mercury capture is one of very few market applications where biochar products might complete with traditional activated carbon products, with the other being those remediation applications where soil decontamination due to legacy pesticides or ordnance residues are preventing significant plant growth.
In the mercury marketplace, biochar is at a disadvantage due to the presence of established suppliers from the activated carbon producers.
In contrast, in remediation, biochar has the advantage that it can provide the initial detoxification requirements, followed by providing the added benefits of improving the soil as a growing medium for all forms of vegetation.
To date, there have not been sufficient reliable suppliers of biochar products to allow the demonstration of the at-scale value propositions in specific biochar markets. Thus, the issue of how cost-effective is biochar in reducing water and fertilizer requirements in specific markets such as corn cultivation is basically unresolved, although credible studies are accumulating in the literature and within individual industrial demonstrations.
Furthermore, in the absence of specific market opportunities that demonstrate the value of biochar, financing biochar production capacity is stymied. The development gridlock is slowly being resolved and rapid growth in biochar capacity and adoption is anticipated over the next decade. There are some external drivers that are also promoting biochar adoption, including atmospheric carbon dioxide levels and concerns driven by consequences of climate change.
As such, it represents carbon removed from the air and converted into a form that will remain in the soil and out of the atmosphere for centuries or longer.
Unfortunately, to date, the direct financial incentives for sequestering carbon dioxide have been insufficient to significantly stimulate biochar production. Frankly, it is impossible to predict how the climate driver will or will not stimulate the future biochar production and utilization patterns.
Additional, and equally powerful, drivers for the adoption of biochar are the documented improvements in water requirements in agriculture due to improved moisture retention and management by biochar-enhanced soils. With the improved water retention, the concurrent phenomenon of loss of soluble soil nutrients by leaching, when excess precipitation extracts nutrients out of the soil, is suppressed. It is the combined improvements in water and fertilizer efficiency by an existing growing method, coupled with the potential benefits of enhanced soil health due to improved soil microbiology, that create a powerful economic argument for the widespread adoption of biochar.
However, only time will tell how it will all play out. Biochar can improve water quality, reduce soil emissions of greenhouse gases, reduce nutrient leaching, reduce soil acidity, and reduce irrigation and fertilizer requirements. Are wood coals good for the garden? Wood ash is an excellent source of lime and potassium for your garden. Not only that, using ashes in the garden also provides many of the trace elements that plants need to thrive.
How do you make your own charcoal? Steps Locate an area where you can build an outdoor fire. You may be able to do this in your backyard, or you may need to secure a different site with a permit.
Get a metal drum. Pick out wood to make into charcoal. Fill the drum with the cured wood. Prepare to light a bonfire. Burn the bonfire. Remove the lump coal. How do you activate biochar? In general agricultural usage, the four methods of activating biochar are: Incorporate into a mix of biochar, worm castings, garden compost, organic fertiliser and water. Digging biochar into an active compost pile. Mix raw biochar into livestock bedding, chicken coops and the like.

Learn More Contact Us Biochar, charcoal, and activated carbon: An overview Biochar, charcoal, and activated carbon can be broadly defined in the following ways: Biochar is a carbon-rich solid that is derived from biomass organic matter from plants that is heated in a limited oxygen environment.
Biochar is intended for agricultural use, and is typically applied as a soil amendment, which is defined as any material that is added to soil to improve its physical properties, such as water and nutrient retention. Charcoal is also a carbon-rich solid that is derived from biomass in a similar manner. Charcoal is generally intended for heating or cooking, and is commonly associated with barbequing. Activated carbon is a carbon-rich solid that is derived from biomass or other carbonaceous substances such as coal or tar pitch, using pyrolysis.
This high adsorption capability allows activated carbon to be effective at removing contaminants from water and air, which is why activated carbon is typically intended for remediation or purification projects.
What do biochar, charcoal, and activated carbon have in common? Producing carbon-rich solids through pyrolysis The main commonality between the three is the way they are produced. This process opens the pores of the carbon to increase its surface area. Chemical processes involve mixing a source material like wood with a chemical like phosphoric acid, then dried and carbonized.
The chemical prevents the resulting char from shrinking, yielding a structure with higher porosity. Chemical composition Biochar, charcoal, and activated carbon can also be similar on the chemical level.
