REDUCING SINGLE-USE CONSUMER PRODUCTS Municipal Approaches to Reduce Single-Use Consumer Products in Maine by Travis Wagner Maine’s solid waste management hierarchy prioritizes reduction and reuse over recycling. While most municipalities in Maine have focused on increasing recycling, they have undertaken minimal efforts to specifically foster source reduction and reuse. In this paper, Travis Wagner examines the approaches adopted in Maine by the state and by municipalities to reduce the consumption of single-use consumer products including bans, fees, consumer education, choice architecture, and retail take back.

    SEEDS Student Reports 1 UBC Social, Ecological Economic Development Studies (SEEDS) Student Reports An Investigation Into Compostable Plastic Bags Sicong Liu Ian Moult Boguslav Long University of British Columbia APSC 261 November 2009 Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community. The reader should bear in mind that this is a student project/report and is not an official document of UBC. Furthermore readers should bear in mind that these reports may not reflect the current status of activities at UBC. We urge you to contact the research persons mentioned in a report or the SEEDS Coordinator about the current status of the subject matter of a project/report.” The University of British Columbia Faculty of Applied Science APSC 261 An Investigation Into Compostable Plastic Bags Instructor: Mr. Dipanjan Sengupta Group members: Sicong Liu Ian Moult Boguslav Long ABSTRACT Plastic packaging, and in particular plastic bags are one of the most commonly found items in landfills. In an attempt to improve the sustainability of the new Student Union Building at U.B.C. biodegradable plastic bags are being considered. This report will focus on the use of biodegradable plastic bags in the new SUB building at U.B.C. and on which products currently available on the market would be best suited for this application. Three different types of biodegradable plastics are reviewed. These are starch based plastics, poly- lactic acid (PLA) plastics and poly-3-hydroxybutyrate plastics, all of which were chosen as they are the most readily available.
