Wood Products - Production, qualification and certification

Recommended Prerequisites

Wood structure and properties.

Bio-based materials.

Construction materials.

Teaching Methods

The teaching method consists on the presentation of materials in the form of theoretical-practical classes, always with the concern of presenting and discussing case studies on each theme, framing the reality of the Portuguese wood processing industry in the European panorama. Seminars with industry experts are planned. The evaluation method will mainly focus on the completion of a written exam (70%) and on the delivery of a study visit report (30%).

Learning Outcomes

Present the different solutions in terms of wood products. Basic concepts in the area of production and qualification of wood-based products. Legal and operational framework for product certification. Presentation of tools and methodologies for the prescription of wood products.
