What is bio isobutanol?
Bio isobutanol is a bio-based alcohol produced through fermentation or as a higher alcohol fraction recovered from fusel oil, a co-product of bio-ethanol distillation. It combines solvent properties with the energy density and blending characteristics needed in advanced fuel applications.
How is isobutanol made?
Isobutanol is produced through two primary methods: the chemical oxo process and biotechnological fermentation.
In the oxo process, propylene is hydroformylated to aldehydes and then hydrogenated to alcohols. Alternatively, sustainable bio-based isobutanol is created by fermenting plant-derived sugars or agricultural waste using specialised micro-organisms.
Nedstar is your reliable partner for sustainable, bio-based isobutanol, supporting your low-carbon and circular-economy strategy.

Different bio-based grades of isobutanol
1G - First generation
The first generation of isobutanol is produced from sugar or starch feedstocks such as sugarcane, corn, or wheat. 1G is available with ISCC+ certification and GHG add-on documentation.
2G - Second generation
The second generation of isobutanol is derived from lignocellulosic waste, agricultural residues, and other non-food biomass. 2G has superior GHG reduction credentials; it qualifies under EU advanced biofuel mandates (RED III Annex IX).

Frequently Asked Questions
What is the other name for isobutanol?
Isobutanol is most commonly known by its IUPAC systematic name ‘2-methylpropan-1-ol’. Within industrial and chemical contexts, it is also frequently referred to as isopropylcarbinol, 2-methyl-1-propanol, IBA, or simply isobutyl alcohol.
Is isobutanol a biofuel?
Isobutanol is a high-energy advanced biofuel when produced from renewable biomass. When derived via fermentation of organic feedstocks, it provides a certifiable, low-carbon alternative that supports global decarbonisation goals and rigorous industrial sustainability standards.
Is isobutanol safe?
Isobutanol is safe for industrial use when handled according to standard safety protocols. It is readily biodegradable and does not bioaccumulate, making it a lower-impact choice for the environment. Always consult the Safety Data Sheet (SDS) for precise handling, storage, and personal protective equipment (PPE) requirements.
