RUG/Pennsylvania/State College/Waste Reclamation System
Penn State RUG has begun very preliminary initial research on a waste recramation system for turning polyethylene into filament. Further research will be conducted over coming semesters and information will be updated here.
Different types of polyethylene are being considered as material choices. Polyethylene has a low melting point, can be melted and reshaped repeatedly, and produces little to no fumes. Two different types are High Density (#2) and Low Density (#4).
HDPE begins to "brown" when heated beyond 300 degrees F.
