Sustainnovation - Transparent Wood
Transparent wood is an eco-friendly alternative for use in engineering applications, such as transparent panels. It can be used for energy-saving purposes, such as heat-storage, thermal insulation, and controlled use of natural light. Transparent wood is also an aesthetic material with many possible applications in interior design.
Transparent wood was first introduced in 2016, when scientists identified methods for removing light-absorbing lignin and replacing it with a resin material. Unfortunately, the process required the use of environmentally harmful chemicals which also weakened the wood. Researchers have now successfully tested an eco-friendly alternative made using citrus waste (such as orange peel) produced by the orange juice industry. The material is made with no solvents and all chemicals are derived from bio-based raw materials.
Timber is a naturally renewable material – provided it is used in a managed way, we will not deplete the world’s finite resources. Choosing to build with timber where appropriate instead of more ‘energy-hungry’ materials such as concrete and steel can reduce the amount of embodied carbon associated with that building. Transparent wood is also stronger and lighter than glass, contributing to reductions in building time and waste.
