UK-based Filamentive offers an environmentally-friendly approach to 3D printing, including a variety of recycled filaments. However, empty filament spools can still pose a problem; while some choose to keep them, many simply discard empty spools that then end up in a landfill instead of being appropriately recycled. Filamentive offers a solution, however, through its new empty spool return initiative, which both reduces waste and leads to cost savings. Any brand of spool is eligible for the program, so long as it meets Filamentive's terms, and those participating will receive a discount on future orders. Read more about the program at
