Plastic Newspaper Sleeves and Plastic Cups

Hello,

Is anyone aware of a current study that looks at the environmental impacts of paper cups vs. plastic cups vs. the biodegradable "plastic" cups? We have a looming landfill crisis in my area, so I'd like to see plastic disposables discontinued. However, I know this is a complicated issue, and landfill space is not the only issue. Secondly, does anyone know of a newspaper that has discontinued delivering the daily paper in a plastic sleeve and found a more sustainable substitute (or no substitute!)

Thanks,
Kate Corwin
