Sustainable Transparent Wood from Citrus Peel Extract

Date:May 04, 2021

Country: Sweden

Application

• Smart windows with enhanced transparency and energy efficiency.
• Eco-friendly lighting and heat storage solutions using transparent wood.

Description

Scientists at Sweden's KTH Royal Institute of Technology have developed a sustainable version of transparent wood by using a monomer derived from citrus peel extract (limonene). This eco-friendly material, which replaces synthetic polymers, offers enhanced transparency, strength, and elasticity. With optical transmittance of 90% and low haze, it holds promise for applications in smart windows, lighting, and heat storage. The research opens up innovative possibilities for environmentally friendly construction materials.

 

 

Pathway Description:

The process begins by extracting lignin from wood, which removes its color and rigidity. The resulting porous material is then filled with limonene acrylate, a monomer derived from citrus peel extract. This eco-friendly filling enhances the wood's transparency and strength. The final material achieves high optical transmittance and is suitable for structural applications.
