Ultrasound-assisted production of lignin nanoparticles (BIOMAC)

This CEN Workshop Agreement (CWA) provides a set of requirements and guidelines and outlines the methodology for the pilot-scale production of LNPs with controlled particle size using an ultrasound-assisted process and water as the liquid medium. The methodology applies to lignin sourced from different types of biomass, such as hardwood, softwood, and non-wood biomass, processed through a custom-made ultrasound-assisted pilot line. The following document provides:
- Guidelines for setting up and operating the ultrasonication (US) equipment to ensure consistency and repeatability of LNPs production. This is covered in Section 5.1.
- The technical parameters necessary for the ultrasonication treatment of lignin to acquire LNPs with specific properties, such as particle size, morphological and structural characteristics. This is covered in Section 5.2.
- Quality control measurements and testing protocols to assess the LNPs' physicochemical properties, ensuring they meet specifications suitable for various industrial applications. This is covered in Section 5.3.
