【 摘 要 】

Petroleum-based polymer materials have been extensively developed owing to their low cost, easy formability, low weight, and corrosion resistance. Beyond the performance and economic aspects, life cycle assessment is also important requiring a plan for reuse, recycling or disposal. Disposal requires a short composting time, but most petroleum-based materials take many years to compost, some not breaking down even after centuries. One approach to more environmentally compatible materials involves harnessing natural materials like wood and bone. These natural materials (whether naturally or artificially produced) are inherently renewable, not requiring the millions of years of fossilization necessary to produce petroleum-based materials.
