Flexible polyurethanes, renewable fuels and seasonings in microalgae oil waste streams.

A new study aims to develop a scalable method for producing microalgae polyols for polyurethane synthesis from waste oil derived from algae biomass.
has become an important focus for the next generation of materials, algae biomass provides a less environmentally impacting raw material that can be used for a variety of purposes.
omega-3 fatty acids are isolated from algae oils, residual oils provide a valuable basis for petrochemical alternatives

. However, unlike vegetable oils, algal oils contain organic contaminants, including photochromes and hydrophobic cofactors, which can complicate preparation methods.
researchers converted Omega-3 depleted Nannochloropsis saline oil (mainly made of palmic acid and palm lysolic acid) into impurities and purified it as a base material for flexible polyurethanes, while producing fennel (HA) as a prelude to flavor and flavor.
the extraction of organic pollutants
converts free fatty acid mixtures into soft soaps to extract organic contaminants, urea complexes provide isolated palm lyicing acid, which is then broken down to produce AA and HA. Bio-based polyester glycols are prepared by AA via esterification to provide polyol monomers for flexible polyurethane foam preparation.
modified HA by-products to produce the flavoring agent methamphetate, and de-pyrethroids to produce hexane as a renewable solvent. This scalable process can be carried out on oil from a variety of algae species, providing valuable monosomes from highly sustainable sources.
the study has been published in the 10th issue of Green Chemistry 2020.
