Product Information
What is activated carbon?
Activated carbon, also called activated charcoal or active carbon, is a versatile and porous material used as an adsorbent.
It is specifically designed to have a large surface area, making it highly effective for purifying, deodorising, and
decolourising liquids and gases. It is commonly derived from sources like nut shells, coal, or wood.
What is an adsorbent?
An adsorbent is a material with mechanical/chemical properties that causes different substances to physically or
chemically adhere to the surface. The high surface area and pore structure of activated carbon make it a very effective
adsorbent. Activated carbon is especially attracted to organic molecules and some heavy metals, making it an excellent
material for cleaning up contamination.
What is your activated carbon made from?
Hyera has developed a low-energy process to produce high-quality activated carbon from renewable, sustainable
biomass feedstocks rather than using non-renewable sources like coal. This biomass includes a variety of agricultural and
forestry wastes, such as nut shells and wood.
What are the advantages of our product?
The key advantages of working with Hyera include that the organisation:
-
Utilises byproducts (which valorises or adds value) that would otherwise be burned or discarded.
-
Uses less energy for activated carbon production compared to traditional methods.
-
Reduces the water and chemical consumption typically needed to "activate" carbon char.
-
Tailors the activated carbon properties for specific customer needs.
-
Has a dramatically lowered CO₂ footprint due to lower fuel demands in the production process.
Overall, Hyera's technology provides a more sustainable and environmentally friendly alternative to conventional
activated carbon production.
What types of activated carbon do you offer?
We offer a diverse range of activated carbon products in various sizes, bag sizes, and pore structures. These include
powdered (PAC) and granulated (GAC) forms that are produced in our facilities. The correct product and mesh size
depend on the specific application and are often tailored to customer requirements.
What range of surface areas do you offer?
Hyera offers a variety of surface areas; all of our products have a minimum average surface area of 950m2/g which is ideal for water, wastewater and PFAS contaminant removal. If you require a higher surface area; Hyera can deliver an
array of adsorption capacities and surface areas for numerous applications.

-
Iodine Number (surface area)
-
Density
-
Methylene Blue (dye adsorption)
-

Use & application
What are the common applications of your activated carbon products?
Our activated carbon products are used for a broad range of purposes across municipal, industrial, and residential
applications.
These include water purification, air purification, odour control, removal of volatile organic compounds (VOC), recovery of
precious metals, and remediation of PFAS. In particular, the food and beverage industry uses high volumes of activated
carbon due to its high surface area and corresponding adsorptive properties.
It is even used in cosmetics, whitening toothpastes and medicines for the same adsorptive properties.
How do Hyera's products function?
Activated carbon functions by removing organic contaminants (odours, flavours, volatile organic compounds, PFAS and
chlorine compounds) through adsorption on its expansive pore structure. Activated carbon does not adsorb most salts
(TDS/conductivity)such as calcium, sulphates, or nitrates.
Applied in filters or directly added to soils, activated carbons can effectively adsorb high concentrations of contaminants
from a wide variety of sources such as water, gas, soil, and air.
Adsorption can occur via chemical or physical interactions between the pollutants and the activated carbon surface.
These pores contain hydrophilic and hydrophobic regions (functional groups) that make it favourable for contaminants to
be “captured” by intermolecular forces and attraction (Van der Waals forces and induced dipole interactions).
Contaminants can continue to adsorb to the surface until the pores are “full” (saturated). Once this occurs, the activated
carbon is replaced with fresh (or recently regenerated) activated carbon. The saturated activated carbon can now be
regenerated, incinerated or safely disposed of.
The adsorptive property of activated carbon is what makes it so important for industries requiring remediation and
purification.

and/or biomass producers to adapt our design and establish rollout plans from conception through permitting to
execution.
Environmental Impact
What is the environmental impact of activated carbon production & use?
As a potent adsorbent, activated carbon is used to remove pollutants, which helps to improve the state of our
environment, drinking water, and food. However, historically, the production and use of AC have had significant negative
environmental implications.
Traditional AC production, often from coal, wood, or coconut shells, poses environmental challenges, this includes:
-
Emissions: The use of fossil fuels to create heat and/or power, contributes to greenhouse gas emissions dramatically.
-
Resource Consumption: Traditional production heavily often relies on non-renewable biomass resources, such as coal
(50% of total production), which involves harmful extraction processes and high transport emissions. -
Waste Generation: Improperly managed waste from production (e.g., mine runoff and gas emissions) can pollute or
contaminate local waterways. -
Water and Soil Contamination: When spent activated carbon is improperly disposed of (after use) it can cause
pollutants to return to soil and water bodies.
What happens to activated carbon after use?
When activated carbon's adsorption sites become saturated (or “full”), adsorbed substances may remain/return (desorb),
potentially leading to chemical recontamination, microbial growth, and regulatory breaches if not disposed of properly.
Spent activated carbon is typically removed and then treated off-site, either by regeneration, incineration or safe disposal.
Hyera is focused on developing effective regenerative carbon processes (for GAC) and looking into improvements for
activated carbon lifespan and disposal.
What is the positive social impact of activated carbon production?
1. Health and Community Well-Being
-
Improved Air Quality: Reducing emissions during production helps improve air quality for nearby communities,reducing health risks such as respiratory problems. In wastewater treatment or scrubber applications, activated
-
Carbon removes and retains odours, minimising the industrial impact upon surrounding communities.leaner Water and Soil: Hyera's activated carbon effectively removes harmful substances (e.g., pesticides, PFAS), leaving safer drinking water and healthier ecosystems for communities.
2. Worker Safety and Job Creation
-
Safer Work Environments: Hyera's proprietary low-temperature, process minimises occupational hazards, protecting
workers from exposure to dangerous substances used in traditional activated carbon production, like strong acids and
alkalis.
-
Economic Opportunities: Hyera creates local jobs in the clean technology sector, fostering local employment and
promoting sustainable economic growth in remote areas and small communities.
3. Environmental Justice
-
Preventing Displacement: By relying on agricultural byproducts instead of raw material extraction, Hyera prevents
the displacement of communities and the destruction of habitats.
-
Climate Resilience: By reducing greenhouse gas emissions and energy use in production, Hyera supports global
efforts to combat climate change, which disproportionately affects vulnerable populations.
4. Circular Economy and Community Empowerment
-
Value Creation: Transforming agricultural by-products into high-value activated carbon provides new revenue
streams in agricultural industries while supporting sustainable practices.
-
Community Engagement: Hyera works directly with local industries and stakeholders to implement practical, eco-
conscious solutions. These partnerships help communities to adopt sustainable practices and actively contribute to
reducing environmental impact.
