Here is what the CT Food Association says:
The goal is to reduce the use of ALL single-use checkout bags - plastic & paper!
The hybrid ban on plastic + fee on paper is widely regarded as the most effective approach to address carryout bags. This type of policy eliminates all plastic bags, reducing their impact on plastic pollution and marine litter, and also reduces the consumption of other single-use bags.
Paper bags require marginally fewer reuses than bags for life to make them more environmentally friendly than single-use plastic bags.
On the other hand, paper bags are less durable than other types of bags. So if customers have to replace their paper ones more frequently, it will have a greater environmental effect.
But the key to reducing the impact of all carrier bags - no matter what they are made of - is to reuse them as much as possible, says Margaret Bates, professor of sustainable waste management at Northampton University.
Polystyrene foam cups and food containers make up a lot of litter and pollution. They are not easily recyclable, and their volume fills up overcrowded landfills — when they make it that far.
Once in landfills, styrofoam may not break down for more than 500 years. As litter, it often breaks up into little pellet-like cells and floats away as water pollution, ultimately to the oceans, where it can harm marine life.
While foam containers are not especially toxic in most situations, they can leach styrene, which can be toxic with sufficient exposure. Practical alternatives to foam containers are available.
