Research Evidence
Aim: To identify the most promising circular economy strategy for utilizing cross-laminated timber (CLT) production residues.
Method: Multi-criteria analysis based on literature review.
Procedure: A data matrix was compiled from literature, evaluating potential recycling alternatives for CLT residues against five criteria: production costs, energy consumption, CO2 emissions, market price of the recycled product, and the ratio of final product to wood residues. Multi-criteria analysis was then used to determine the optimal solution.
Context: Wood product manufacturing, specifically cross-laminated timber (CLT) production.
Design Principle
Valorize production byproducts through circular economy principles, evaluating options based on economic, environmental, and resource efficiency metrics.
How to Apply
When designing products or processes that generate waste, conduct a similar multi-criteria analysis to identify the most sustainable and economically viable recycling or upcycling pathways.
Limitations
The analysis is based on existing literature and may not capture all real-world production nuances or emerging technologies.
