We convert palm oil agricultural waste into clean, high-value biomass fuel — a drop-in coal replacement for power plants, cement kilns, and heavy industry. No infrastructure changes required.
We started with a simple conviction: Indonesia’s biomass shouldn’t go to waste. Every community, every landscape, every resource has its own role to play. Kairen was founded on this belief — that agricultural abundance is not waste to be discarded, but energy waiting to be unlocked.

Power plants, cement kilns, steel mills, and factories worldwide produce over 20 billion tonnes of CO₂ equivalent every year — that’s 34% of global greenhouse gas emissions when indirect electricity use is included. Most run on coal. Many face tightening carbon regulations, rising compliance costs, and reputational pressure.
These facilities have decades of operational life remaining. They can’t be shut down overnight. But they can switch fuel. Torrefied biomass is a drop-in coal replacement — compatible with existing handling, milling, and combustion systems. No overhaul required.
For every tonne of palm oil produced, nearly four tonnes of organic residue are generated — shells, fibers, empty fruit bunches. Most is burned inefficiently, dumped, or left to decompose. Meanwhile, industries worldwide are racing to replace coal.
Japan’s 2025 Strategic Energy Plan targets biomass at 5–6% of the national energy mix by 2030. The country operates 290 biomass power plants (7.3 GW installed), with 11 new plants scheduled for 2025 alone. South Korea imported approximately 4 million tonnes in 2023. Torrefied and carbonized biomass production is projected to grow 60–80% annually.

Each step extracts more value from the same raw material. We’re building this capability deliberately, one stage at a time.
We source and supply Palm Kernel Shells (PKS) from plantation partners in Kalimantan, backed by long-term supply agreements securing access to tens of thousands of tonnes annually. Our decade of experience in fuel logistics and bulk shipping means reliable supply chains from plantation gate to port of delivery.
Torrefaction thermally upgrades raw biomass at 270–320°C into hydrophobic, energy-dense bio-coal — a product with near-coal properties from a renewable, carbon-neutral source. Our pellets are engineered for co-firing in existing power plants without infrastructure modifications, commanding premium pricing in export markets.
Higher-temperature processing (350–650°C) produces bio-carbon with fixed carbon content exceeding 90% — a renewable substitute for fossil carbon. Applications include EAF steelmaking, silicon and ferroalloy production, permanent soil carbon sequestration, activated carbon for pharmaceuticals, and emerging use as SAF feedstock. In 2023, global biocarbon production reached 300,000 tonnes against 1.5 Mt capacity — indicating massive unmet demand.
Your customer doesn’t need to spend money on new machines. Torrefied biomass pellets work with existing coal handling, milling, and combustion equipment.

Torrefaction is a thermochemical process conducted at 270–320°C in an oxygen-free environment. It removes moisture, breaks down unstable volatile compounds, and concentrates carbon content — producing a uniform, energy-dense fuel with properties remarkably close to coal, from a fully renewable source.
Our facility is designed to operate without external fuel input, using syngas generated during torrefaction to sustain heating operations. This closed energy loop is a key differentiator for sustainability-focused buyers and investors.
Engineered to meet the demands of industrial co-firing power plants, cement kilns, and heavy industry worldwide.

We’re engineers and operators who’ve spent years in energy, logistics, and sustainability. Working with Kairen isn’t a transaction — we build real relationships. The kind where you pick up the phone, not send a purchase order.
From fuel distribution across the archipelago to bulk vessel shipping, we know how fuel moves from source to boiler. Our supply chain experience is operational, not theoretical.
Kairen wasn’t a pivot. We saw Indonesia’s biomass abundance as a gift that should create value, not pollution. That conviction drives every decision — from feedstock sourcing to technology selection.
Our relationships with mills and plantations aren’t contracts on paper. They’re built over years of shared meals, showing up when it matters, and delivering on every commitment we make.
Whether you’re an industrial buyer seeking coal alternatives, an investor exploring biomass infrastructure, or a plantation looking to monetize waste — we’re ready to talk.
