2  Project began in Summer of 2011  Sampled waste of 17 municipalities and regional transfer stations twice each  Looked at both composition of waste along with method for recycling and waste stream  Only sampled residential “baggable” waste

4  Improving waste management should be a targeted effort  20 years since its inception, the 50% recycling goal has not yet been reached (currently ~ 39%)  Knowing composition will help lead to the most efficient plan of attack  No study of Maine waste has been conducted since 1991/1992 and it is prudent to assume it has changed

5  Waste was broken into 9 major categories  Organic, Paper, Plastic, Other, Construction and Demolition, Metal, Glass, Household Hazardous, and Electronics  Over 60 subcategories were used


7  Collect sample of waste (no. of bags varied by location)  Broke open each bag and settled contents  Sorted into both final subcategories and several category groupings  Weighed bins, tallied results, and emptied contents as bins became full  Resorted bins with groupings as needed or at the end of the day

24  Paper percentage of total waste stream decreased by 23%  Significant decreases in Cardboard and High Grade Office Paper  Substantial decrease (75%) in Newsprint Type of Paper 91/92 % of Total Waste Stream 2011 % of Total Waste Steam Corrugated cardboard High grade office Magazines/ catalogs Newsprint Telephone books Total of all paper

25  Plastics bag waste cut in half  Rigid plastics has increased by 160%  Plastic percentage of total waste stream has doubled  Plastic Film waste much of increase Type of Plastic 91/92 % of Total Waste Stream 2011 % of Total Waste Stream Plastic bags All HDPE Rigid plastics Total of all plastic

27  Broken down by town sampled, variations are apparent  Distribution skewed to the right  Some towns have much better recovery rates

28  Distribution is tighter for clear glass containers and near normal  Standard deviation is less than half of newsprint


30  Classification is by:  What is widely recycled around the state  Compostable without significant effort  What is currently not diverted in a significant amount of locations around the state  Not a perfect analysis due to fungible nature between categories of many items.

32  Where can the next advances in recycling come?  What can be improved?  Methods, actions, enforcement, technology.  What can be added and/or promoted everywhere?  Textiles, film, grocery bags, hard plastics not #1-7, composites, etc.

33  How can we better utilize compositing to decrease the waste stream  Regional composting?  Is it feasible? Cost-effective? What process should be used? Can we control the smell?  Backyard composting  Public perception, animal issues, individual responsibility.

34  What are best practices in Waste Management?  Pay-as-you-throw, Single-Stream, curbside collection, drop-off, mandatory recycling, HHW collection, citizen education, etc.

35  State is still not near 50% recycling goal  Waste composition has transformed with time  Plastic waste on rise as paper and glass decline  Recyclables in waste stream is over 20% and compostable material is nearly 40%  Top 10 waste subcategories account for 73.05% of the waste  There are widespread variations by town and by subcategory that are observed
