AI Technical Summary

Problems solved by technology

[0002] Boards are widely used in decoration, but forest resources are limited, and the use of solid wood boards for decoration will cause a lot of waste of boards
In the process of solid wood processing and manufacturing, a large amount of sawdust is produced, and a large amount of straw is also produced during the harvest season in rural areas. The traditional way of processing sawdust and straw is to discard them directly, resulting in a large waste of resources.
