All Theses
Polylactic acid (PLA) is a biopolymer made from renewable resources such as sugar and corn. PLA filament is a popular material used in Fused Deposition Modeling (FDM) 3D-printing. While this material has many advantages, all the failed parts, support structures, rafts, nozzle tests, and the many prototype iterations during the 3D-printing process contribute to the plastic pollution and release of greenhouse gases. Although PLA is biodegradable, it can take years to degrade in landfills. Instead of throwing away PLA waste and buying new filaments, PLA can be recycled. Amongst the different recycling technologies, mechanical recycling is the most environmentally friendly. …

Trademark's Grip Over Sustainability, Daniel R. Cahoy
University of Colorado Law Review
Entrepreneurs and larger firms are waking up to the fact that there is a viable market for recycled, repaired, and even upcycled goods. There is also an increasing desire on the consumer end for more sustainable products as well as measures to reduce landfill and other product disposal harms to the environment. Although some legal barriers to this new market are being actively debated, other barriers have taken a back seat and seem primed to surge only when increased business activity exposes the liability. This is the case with trademark law, which has the potential to substantially deter the small-firm …
