Lignin-Based Alternative to Bisphenol A for Sustainable Plastics

Date:8 Sep 2023

Country: Belgium

Application

• Development of eco-friendly, non-toxic plastics and resins.
• Replacement of bisphenol A (BPA) in manufacturing processes for safer, sustainable products.

Description

A research team developed a sustainable alternative to bisphenol A (BPA) using lignin, a component of wood, to create bisguaiacol compounds. These compounds are synthesized through reactions involving alkenes and bio-based arenes, catalyzed by a recyclable zeolite catalyst. The new lignin-based materials offer a non-toxic, bio-based option for producing plastics, eliminating the need for fossil fuels and reducing health risks associated with BPA. Initial tests confirm the safety and effectiveness of the new compounds in creating environmentally friendly plastics.

Pathway Description:

The process used in this project involves the creation of bisguaiacols, which are lignin-based compounds, as a replacement for bisphenol A (BPA). The reaction is initiated by using a recyclable zeolite catalyst (H-USY) to catalyze the reaction between an alkene and a bio-based arene such as guaiacol. These bisguaiacols are then used to produce plastics and resins, offering a sustainable, non-toxic alternative to BPA. The process also utilizes lignin, a renewable resource, reducing dependence on fossil fuels.
