Revision as of 20:43, 19 October 2010
This is a research project in partnership between Engr308 Technology and the Environment and the City of Arcata, during Fall 2010, to explore the reasons for and effects of a single use plastic ban bag would have in Arcata, Humboldt County.

Environmental Impacts
The carbon footprint of plastic (LDPE or PET, poyethylene) is about 6 kg CO2 per kg of plastic. Give a few more details... especially the assumptions. [2]
Studies have been done in major cities across the globe to determine the impacts of one-time use plastic carryout bags on the environment. Here is the data from one such study completed in Los Angeles County in 2009. [3]
In this section, emissions related to plastic carry-out bags are compared to those of paper carry-out bags
