Sustainable Biomass Energy
Palm kernel shell, graded.
A by-product of the Indonesian palm industry, screened at origin and supplied against ISCC and GGL chain-of-custody.
- Calorific value
- 3,800–4,800kcal/kg
- Fixed carbon
- 18–24%
- Moisture
- ≤15%
- Incoterms
- FOB / CIF
Nothing is grown for this fuel. The shell already exists as waste at every palm oil mill — the work is getting it clean, dry and onto a vessel without losing the calorific value you contracted for.
Five stages, one chain of custody.
The mill takes the oil. The shell is what remains.
Palm kernel shell is the hard casing left after the kernel is crushed for oil. It is a by-product of an existing industry, not a crop grown to be burned.
Graded for size before it is graded for heat.
Shells are screened to 5–40mm and checked for foreign matter. Fibre, dirt and kernel fragments raise ash and abrade boiler feed systems, so they come out at origin.
Moisture is the whole game.
PKS gains moisture fast in the open, and every point of moisture is calorific value the buyer paid for and will not receive. Storage is covered and managed.
Loaded in bulk, against ISCC and GGL chain-of-custody.
Port-adjacent capacity for bulk vessel and container programmes, with certified traceability back to the originating mill.
A drop-in solid fuel on arrival.
Dense, uniform and low in sulphur and chlorine — suited to dedicated biomass plant and to coal co-firing without capital modification.

Sustainability certification
Certified chain-of-custody from mill to vessel, audited against EU renewable-energy criteria.
Green Gold Label
Independent traceability standard for sustainable biomass sourcing.
Not grown to burn
Palm kernel shell is a residue of oil extraction, not a dedicated energy crop.
