New study explores recycling of post-consumer fibreboards for sustainable MDF production

Research by Percy Alao focuses on the recycling of post-consumer medium-density fiberboard (MDF) waste using advanced methods like thermomechanical pulping (TMP) and impact reactor processing. The study highlights how recycling affects fiber properties critical to MDF quality.

Using Dynamic Image Analysis, the research shows that recycled fibers are shorter than virgin fibers, and there is an increase in pH and nitrogen content, suggesting the presence of residual resin in the recycled material. Although microscopic imaging did not reveal residual resin, chemical analysis indicates it remains in the fibers.

This work is key to understanding how recycled fibers—substituted at rates of 15-25%—might influence the performance of new MDF products. Further research is needed to determine the practical impact of these changes on MDF quality and durability.
