You need to judge the materials to see which is the most sustainable. Remember that the data assumed both window frames went to landfill for disposal. Recycling could influence your decision.

Environment
Which material has the smallest environmental impact?
How do rate things like global global warming and the amount of waste produced?
Economic
How does production provide jobs for people?
Social
