What is Activated Carbon?

    Activated carbon is a highly porous form of carbon used to remove impurities from air, water, industrial processes and gold recovery. Made from raw materials like coconut shells, coal, or wood, it is processed at high temperatures to create a large internal surface area. This structure enables it to adsorb contaminants effectively, making it ideal for purification, deodorisation, and precious metal recovery. Activated carbon is widely used in water treatment, air filtration, food processing, precious metal recovery and pharmaceuticals due to its ability to trap toxins, odours, and unwanted chemicals at the molecular level.

Activated carbon

01

Types of Activated carbon

Activated carbon is classified based on raw materials such as coconut shell, coal, and wood. Coconut shell carbon is hard and dense, offering high purity and a fine pore structure. Coal-based carbon, derived from bituminous or anthracite coal, provides a balanced mix of micro- and mesopores. Wood-based carbon is lighter with a more open pore structure due to its fibrous origin. Other sources include peat, lignite, and petroleum pitch, each influencing the physical and chemical properties of the final product.

Why Choose Coconut shell activated carbon

Coconut shell activated carbon is widely preferred due to its superior hardness, high density, and excellent adsorption capacity. It has a predominantly microporous structure, making it highly effective for removing small organic molecules, heavy metals, and odors. Its high abrasion resistance ensures durability during repeated use, especially in pressure-driven filtration systems.

Coconut shells are a agricultural by product, sustainable resource, making them environmentally friendly compared to fossil-based raw materials. Additionally, the carbon has low ash content and high purity, which is critical for applications in water purification, air filtration, and gold recovery. Its consistent quality and performance make it a top industry choice.

Production process of coconut shell based activated carbon

The production of coconut shell-based activated carbon involves two main stages: carbonization and activation. First, clean, dried coconut shells are heated in a controlled, low-oxygen environment at around 600–700°C to produce charcoal through carbonization. This removes volatile components and creates a carbon-rich structure.

Next, the charcoal undergoes activation using steam or CO₂ at high temperatures (800–1000°C), which develops a highly porous structure by opening and enlarging internal pores. After activation, the material is cooled, crushed, and sieved into desired mesh sizes. Finally, it is washed and dried to remove impurities, producing high-quality activated carbon ready for packaging.

Uses and Benefits

Benefits of Using Coconut shell Activated carbon

Coconut shell activated carbon offers numerous benefits, making it a preferred choice across industries. Derived from a renewable and eco-friendly source, it features a high surface area and microporous structure, allowing for superior adsorption of impurities. Its exceptional hardness ensures minimal dust and longer operational life, while its low ash content makes it ideal for sensitive applications like drinking water and pharmaceuticals. At CG Carbon, our plant is powered 100% by solar energy during daytime operations, and we meet six months of our water needs through efficient rainwater harvesting systems—reinforcing our commitment to sustainability and responsible manufacturing.

Renewable Raw Material

Coconut shells are a sustainable, eco-friendly byproduct of the coconut industry, making them an ideal raw material. Unlike wood or coal, they don’t contribute to deforestation or depletion of non-renewable resources.

High Hardness and Low Dust

Coconut shell carbon has excellent mechanical strength, reducing product loss during handling and minimizing dust generation in filtration systems.

Superior Adsorption Properties

With a high surface area and microporous structure, coconut-based carbon is especially effective in adsorbing small, low-molecular-weight contaminants like VOCs, chlorine, and organic compounds.

High Purity

It has very low ash and heavy metal content, making it suitable for sensitive applications such as pharmaceuticals, food processing, and drinking water purification.

Long Life Span

Its high abrasion resistance ensures longer operational life in fixed bed filters and industrial systems, reducing maintenance and replacement costs.

Sustainability at CG Carbon: Commitment to greener future, safer products

At CG Carbon, sustainability is at the heart of our operations. From eco-friendly raw material sourcing and a carbon-neutral production process to a zero-waste approach and active water conservation, we are committed to reducing our environmental impact. By focusing on local sourcing, we also minimize transportation-related emissions, further lowering our carbon footprint.

Unlike traditional activated carbon made from wood or coal, we use coconut shells—a renewable, sustainable agricultural byproduct that would otherwise go to waste. This approach we avoids deforestation. Through proper treatment, we transform discarded coconut shells into high-quality activated carbon while supporting a circular, low-waste economy.

Our production facilities are powered in part by a large-scale solar power system, helping us generate clean energy on-site. Additionally, we’ve implemented rainwater harvesting systems across our campuses, promoting sustainable water use and reducing dependence on external sources. These initiatives reflect our strong commitment to long-term environmental
