Country: Japan

Application

• Sustainable Chemical Production: Methyl levulinate and methyl lactate can be used as bio-based alternatives in the production of solvents, plastics, and fuels.
• Algae Biomass Utilization: This method offers a way to repurpose algal residues for industrial applications, reducing waste and dependence on fossil fuels.

Description

A team of Japanese researchers developed a method to convert algal residues into valuable chemicals, methyl levulinate and methyl lactate, using algae as a carbon source. By employing a one-pot synthesis method with methanol and selective catalysts, the process yields high quantities of methyl levulinate. This innovative approach highlights the potential of algae biomass to replace fossil fuels, reducing environmental impact and resource depletion. The study opens possibilities for sustainable chemical production from algae.

Pathway Description:

The process involves preparing algae by centrifuging, drying, and freezing, followed by suspension in methanol. A one-pot synthesis method at 160°C is used with selective catalysts to degrade starch molecules and algae. This results in the production of methyl levulinate and methyl lactate through retro-aldol reactions. The process combines biochemical and chemical methods to convert algal residues into valuable chemicals.
