Sustainability, Circularity, and Innovation in Wood-based Panel Manufacturing in the 2020s: Opportunities and...

Area of Science:

• Materials Science
• Sustainable Manufacturing
• Forestry

Background:

• Current wood fiber supplies for wood-based composite panels (WBCPs) face threats from climate change and competition.
• Unconventional sources like logging residues and fire-damaged wood are increasingly available but underutilized.
• Recycling post-consumer wood-based composite panels presents significant technological challenges.

Purpose of the Study:

• To explore the use of unconventional wood sources in manufacturing particleboard, MDF, and OSB.
• To review advancements in lightweight and multifunctional wood-based composite panels.
• To identify opportunities and challenges for improving sustainability in the WBCP industry.

Main Methods:

• Literature review of scientific publications on wood-based composite panels.
• Analysis of raw material properties and technological limitations.
• Examination of emerging materials for panel production and functionalization.

Main Results:

• Unconventional wood sources can be utilized, but their impact on panel properties requires careful management.
• Lightweight and multifunctional panels with fire resistance, conductivity, and antimicrobial properties are being developed.
• Natural substances show promise as eco-friendly alternatives to conventional additives.

Conclusions:

• Diversifying wood sources and improving recycling are key to enhancing WBCP industry sustainability.
• Hazardous chemicals in adhesives and coatings hinder panel recyclability and circular economy efforts.
• Further research is needed to overcome recycling barriers and promote greener materials in WBCP manufacturing.
