The first set of readings explains how a Life Cycle Analysis (LCA) is prepared. Pay attention. Not all LCAs are impartial. When comparing plastic to paper, for example, an LCA prepared by the chemical industry emphasizes energy and water use, but neglects toxics and air emissions.
Here's a really interesting analysis of the life cycle benefits of plastics in cars and another for RVs. The image below is hyperlinked to the original site.
This is a very interesting site that explains how to really do a LCA. The site is very scientific, but worth studying. But NOTE: The diagram doesn't include energy, and if you are concerned about things like air pollution and global climate change, embodied energy is critical.
The life cycle of a plastic product produced by the American Plastics Council
The life cycle of paper and plastic bags prepared by the Michigan DEQ.
The Institute for Lifecycle Environmental Analysis compares paper and plastic bags.
The Environmental Literacy Council tackles paper versus plastic.
A 29-page report on paper versus plastics including biodegradable plastic.
Question: After looking at all the paper versus plastic sites, which do you think is better for the environment: plastic or paper?
Here's an excellent example of industry-supported research. Can you detect the biases? Lifecycle analysis of PVC prepared by the Chlorophiles. "Chlorine: You Live By It!"
