Abstract: Disposable expanded polystyrene fast food container is one of the main causes of “white pollution”. A comparison study on Expanded polystyrene（EPS） fast food containers and photicly/bioticly degradable ones has been carried out using the life-cycle assessment (LCA) methodology. The result shows that the environmental impacts of the two kinds of fast food container are mostly originated from production stage, and the main impacts are resources damage. The environmental harmony of EPS fast food container is higher than photicly/bioticly degradable ones when 70% of it is collected and recycled after being used. A comparison study on waste disposal scenarios shows that collecting and recycling has less environmental impacts than incinerating or landfilling for EPS fast food container, and incinerating has less environmental impacts than landfilling for photicly/bioticly degradable fast food containers. Some suggestions on ecological design of two kinds fast food container are put forward.
