Lignocellulosic Biomass from Grapevines as Raw Material for Particleboard Production

The study aimed to determine the suitability of agricultural lignocellulosic biomass in the form of vine pruning waste for particleboard production. Two variants of particleboards with densities of 650 kg/m(3) and 550 kg/m(3) containing a varied amount of vine pruning waste (0, 25, 50 and 100%) were evaluated. The strength (MOR, MOE and IB), thickness swelling and water absorption after immersion in water for 2 and 24 h were tested. The results revealed that vine pruning waste affected the board thickening and reduced strength properties. Boards with a 50% share of waste met the minimum requirements of strength properties specified in the EN 312 standard for boards with a density of 650 kg/m(3). However, boards with a density of 550 kg/m(3) entirely made with vine pruning waste met the minimum requirements of strength properties of the EN 16368 standard. Moreover, the pruned material reduced axial forces during drilling, swelling and water absorption.

Automated summary

This study evaluated the suitability of agricultural lignocellulosic biomass (vine pruning waste) for particleboard production and found that the waste content affected the thickness and strength properties of the boards. Boards with 50% waste content met the minimum strength requirements. Pruning waste also reduced axial forces during drilling and improved swelling and water absorption properties.
