Life Cycle Assessment of Reprocessed Cross Laminated Timber in Latvia

It is expected that Cross-laminated timber (CLT) and other engineered wood products will experience rapid growth in the coming years. Global population growth is requiring more housing units, at the same time the negative impact of construction industry cannot stay in the same level as today. Altern...
