Industrial Detail

Charcoal has been used for the production of iron since Roman times and in modern times charcoal is used as a carbon source in the ferro-alloys industry.  Over time significant natural forest destruction and deforestation has taken place as rogue producers have decimated forest ecosystems to supply industrial demand.  However, sustainable forestry with regular replanting provides a clean and efficient industrial charcoal supply chain with a strong competitive advantage…and not only for companies focused on sustainability.

GCS bio-chars are among the highest quality. Under tightly controlled operating conditions, GCS produces bio-chars that are:

Carbon-rich: Up to 95% carbon
 Very low in ash: As low as 1%
 High surface area: As high as 625 m2/g

With the goal of sourcing highest quality feedstock, we use our technology and decades of experience in search of optimal operational process and controls to produce high-quality bio-carbon reductants while simultaneously improving the sustainability of our business and our customer’s supply chain.

Concrete is one of the world’s most widely consumed products and concrete is the greatest consumer of sand—one mile of highway requires in excess of 45,000 tons of sand.  Biochar tested in concrete has been shown to:

 Increases strength
 Reduce cracking
 Reduce water evaporation in the curing process
In addition to the benefits for concrete, there is a significant opportunity to store a carbon in the concrete in our buildings, roads and sidewalks to reduce the carbon footprint of the cement and concrete industry.
While much research continues into the properties most important to cement, we do know that particle size, porosity, surface area and water holding capacity are key factors impacting concrete.  We are working with industry groups and customers to deliver high-quality biochars that meet the industry’s needs.

In the US over 90% of roads and over 80% of runways and parking lots are paved with Asphalt.  Percentages are similar in Europe.  Much research is going to improving asphalt aggregates and bitumen, the gooey binder in asphalt.  Some of the historical aggregates and fillers are not well suited to newer bitumen composites such as recycled tires.  However, carbon-based materials have long been used as asphalt filler since they are considered inherently compatible with bitumen. 
A number of studies are actively researching the addition of biochar to bitumen with very positive results.  Studies show biochar to:

 Improve the penetration and stiffness of bitumen
 Improve the longevity of road surfaces
 Increase the temperature at which asphalt melts and reduce rutting
With the push for the asphalt and bitumen industries to become more sustainable and reduce their carbon footprint there is a significant role and opportunity for biochar. 

GCS bio-chars are among the highest quality. Under tightly controlled operating conditions, GCS produces bio-chars that are carbon-rich (up to 95% carbon), very low in ash (as low as 1%) and have a high surface area (as high as 625 m2/g). With very high, stable carbon content, GCS bio-chars have the ability to sequester carbon for hundreds of years, if not significantly longer.

Activated Carbon
Activated carbon is a highly porous, carbon-rich product with very high surface area.  Activated carbon is generally manufactured from coconut shell, hard woods, coals and other carbonaceous materials. “Activation” is typically via a chemical or high temperature steam process. The intrinsic pore structure is the key to the performance of activated carbon.

Traditionally activated carbon has been used for air and water purification, medicine, decaffeination, metal extraction, gold purification, waste-water treatment, teeth whitening, filters in gas masks and respirators as well as many other applications.

With demand for lower cost, more sustainable products there has been a rise toward using biochar to replace activated carbon for certain applications. High-quality biochar will act as low cost, high-volume activated carbon but can also be further “activated” either chemically or with high temperature steam.

Our high quality, high-surface area biochar performs well as a broad based, general activated carbon. We are working to develop biochar products that can compete with more traditional sources of activated carbon.
