Palm Kernel Shell Biochar
Palm kernel shell biochar is a carbon-rich material produced through pyrolysis of palm kernel shells, offering high stability in soil, excellent carbon sequestration potential, and improved water and nutrient retention, making it valuable for agriculture and climate mitigation.
Overview
What is Palm Kernel Shell Biochar?
- Palm kernel shells are the hard endocarp of oil palm fruits, usually considered agricultural waste.
- Through pyrolysis (heating in the absence of oxygen at 400–600°C), these shells are converted into biochar.
- The resulting biochar is a porous, black material with high carbon content and alkaline pH.

Key Characteristics
Scientific Properties of PKS Biochar
Palm kernel shell biochar undergoes significant property improvements through pyrolysis, making it superior to raw shells for both industrial and agricultural use.
Carbon Content
Increases from ~46% in raw shells to ~73% after pyrolysis, delivering exceptional carbon density for fuel and sequestration applications.
Long-Term Stability
Low hydrogen-to-carbon (H/C) and oxygen-to-carbon (O/C) ratios (0.32–0.54 and 0.08–0.21) indicate long-term stability in soil.
Surface Area
Expands from 106 m²/g (raw) to 329 m²/g at 600°C, enhancing adsorption capacity for nutrients and contaminants.
Alkaline pH
Strongly alkaline (9.3–12.0), useful for neutralizing acidic soils and improving soil chemistry.
Water Retention
Improves significantly, holding up to 6.21 g water per 10 g biochar at 500°C pyrolysis temperature.
Nutrient Retention
Increases cation exchange capacity (CEC), particularly at lower pyrolysis temperatures (400°C).

Production
Process of Making Palm Kernel Shell Biochar
A controlled five-step process converts agricultural waste into export-grade biochar.
Collection
Palm kernel shells collected as waste from palm oil mills across Nigeria's agricultural regions.
Drying
Moisture is reduced to prepare the shells for controlled pyrolysis processing.
Pyrolysis
Shells are heated at 400–600°C in a low-oxygen environment, converting biomass into carbon-rich biochar.
Biochar Formation
Carbon-rich, porous material is produced with high stability and enhanced surface properties.
Cooling & Storage
Biochar is stabilized, moisture-proof packaged, and stored for export to international partners.

Applications
Use Cases
Versatile biochar solutions for industrial, agricultural, and environmental applications worldwide.
Industrial Fuel Substitution
Replace conventional fossil fuels in manufacturing, cement production, and power generation with a renewable, high-calorific alternative.
Soil Enrichment
Enhance agricultural productivity through biochar application, improving soil structure, water retention, and nutrient availability.

Carbon Sequestration
Stores carbon long-term, reducing greenhouse gas emissions and supporting corporate sustainability programs and carbon credit projects.

Waste Management
Provides a sustainable use for palm oil industry residues, converting agricultural waste into a valuable export product.

Energy Co-Products
Pyrolysis also yields syngas and bio-oil, which can be used as renewable energy sources alongside biochar production.
Soil Science
How Biochar Improves Soil
Biochar creates a biochar-clay organo complex in soil that increases nutrient use efficiency, reduces gaseous and leaching losses, and supports high microbial populations.
- Nutrient use efficiency increased
- Gaseous loss of nutrients reduced
- Soil pH increased
- High porosity and water holding capacity
- Leaching loss reduced
- High microbial population and organic nutrient pool
