The Calgary Herald reports that "Alberta Environment Minister Rob Renner raised the prospect Wednesday of charging coffee drinkers a small deposit on disposable cups in a bid to keep litter from blowing down the province's streets."

The intention is to reduce litter and promote the recycling of disposable cups. It also seeks to increase the use of travel mugs that are capable of long-term and multiple use. Nevertheless, there are issues with recycling disposable cups as many are not easily recyclable due to their varied compositions and a lack of product uniformity. As well, some have cited hygienic issues with storing used cups.
