This section introduces DASI’s core business areas, supplying bioenergy feedstocks by
converting vegetable oils such as used cooking oil into high value eco-friendly materials.
Eco-friendly renewable energy feedstocks refined and filtered from waste resources such as used cooking oil
By pretreating byproducts from food processing, low-grade oils, and industrial residues, materials are recycled into industrial resources and exported as bioenergy feedstocks based on ISCC EU certification and related standards.
Through pretreatment processes, high boiling point components, volatile organic compounds, moisture, and oxidation factors are minimized, ensuring ISCC EU–certified feedstocks.
Primary refining including degumming and vacuum distillation → Secondary refining and filtration pretreatment processes to remove impurities and volatile organic compounds, ensuring compliance with quality standards.
Biodiesel feedstocks, hydrotreated vegetable oil (HVO) feedstocks, and sustainable aviation fuel (SAF) feedstocks
They are used as core feedstocks for various eco-friendly energy products, including biodiesel,
sustainable aviation fuel (SAF), and industrial fuels.

Reduces greenhouse gas and fine particulate emissions and is used as fuel for transportation and power generation.

Next-generation eco-friendly fuel produced through hydrogenation.

Produced by pretreating and processing used cooking oil, then exported as SAF feedstocks.
