Hi Alejandro, There are a range of uses for carpentry waste from reusing wood scraps to wood shavings and sawdust. With wood scraps the goal is to reprocess the remainders for repurposing. It could be using the wood to create parquet flooring pieces or creating joints to bind larger pieces of wood together. Reprocessing the wood may be cheaper than using new wood sources. Wood shavings and sawdust are a little trickier. I looked at a number of websites that listed gardening for mulch and paths, fire bricks, for cleaning to absorb liquid spills, for stuffing of toys, for dog bedding, and for carpentry repair when mixed with a bonding agent, Hope some of these ideas are possible where you live.
