Capability 01 · Bioenergy & Energy Transition

Bioenergy and the low-carbon transition, engineered to be built.

We deliver feasibility, process and engineering design, and independent assessment across bioethanol, biodiesel, biogas and biomethane, sustainable aviation fuel, and CCUS, helping clients turn energy-transition ambition into bankable, buildable projects.

01 What we do

From feasibility to engineering, across the bioenergy spectrum.

Independent, technology-agnostic engineering and advisory across biofuels, biogas, and decarbonisation, grounded in two decades of renewable-energy experience.

01

Bioethanol

Feasibility, process design, and engineering for molasses- and starch-based bioethanol plants, including utilities, layout, and emission management.

02

Biodiesel

Feasibility and engineering for biodiesel and FAME plants, from capacity planning to process and utility design.

03

Biogas & Biomethane

Feasibility, technology selection, and assessment for biogas and biomethane projects, including POME-to-biomethane potential surveys and grid-injection studies.

04

Sustainable Aviation Fuel

Technology selection and pre-feasibility for SAF pathways, evaluating feedstock, conversion routes, and project economics.

05

CCUS & Emission Management

CO2 capture, liquefaction integration, and emission-management planning to support decarbonisation and the energy transition.

06

Energy Transition Advisory

Roadmaps, technology screening, and feasibility for renewable-energy and low-carbon investment decisions.

How we work

From concept to investment-ready engineering.

A staged approach that builds technical confidence at each step, with deliverables matched to the maturity of the project.

Stage 01

Feasibility & Concept

  • Feedstock, market, and supply-chain assessment.
  • Technology selection and configuration screening.
  • Feasibility study with CAPEX/OPEX and economics.
  • Emission, carbon, and sustainability screening.

WHY
Why TKL

Renewable engineering, grounded in operating reality.

01

Operator-grade insight

Our designs reflect how plants actually run, validated against facilities we have built and operated.

02

Two decades in renewables

Deep experience across biofuels, biogas, and the low-carbon transition in Indonesia and the region.

03

Independent & technology-agnostic

We assess and select technologies on the merits, with no allegiance to any single licensor or vendor.

04
