What Other Cities Do Some Minnesota cities have begun addressing storage and conve- es by using wheeled 64 gallon cuts for recycling. Brooklyn Park Brooklyn Center, Crystal and New Hope are sing a system called single stream sdl recyclable material goes into a single cut In a plot program in 2001 theses cities found participation went from 58 percent under to current two sort bin system, to 74 87 percent participation in the single sort system. Newspapers in o SSngle They averaged 23 pounds of recycling set out per household Steam Recycling Cart versus 18 pounds per household with the bin system. While His appears to be moving forward Here are some significant concerns about single stream recycling. The major drawbacks are inability to monitor what is collected at the curbside and additional processing at the facility both of which lead to contamination ofrecyclables. Data on current single str eam recycling facilities shows the amount of material collected that is not recyclable (out [Mows) is 5% or greater and the material not able to be recycled (residual) to be1525 %. Numbers on Waste Management fadi ty in Minneapolis show a lower ate of residual but are preliminary because the facility opened in January 2002 and is not running at full capacity sdso the numbers will be skewed because single sort materials are mixed with two sort and source separated (seven sorts) systems. MotherfactorinfluencingthisisthatWasteMan — agement collects broken glass and sends it to its landfills for use as drainage or cover material. That material is not included in the facility's residual ate even though it ends up in a 1ME11. Residual for Roseville 's current two sort system when it was being processed at a two sort facility was approximately 7 percent, out throws No set to t %. Thus He net mount of material that is successfully processed in a single str eam system can go down even Hough the amount collected goes up. It s not necessarily the single stream method that leads to increased participation. In 2001 St Paul s Eureka Recycling that runs recycling programs for He City conducted a plot program on recycling behaviors. The study included single stream with carts, two stream with cuts, two stream with bins with weekly collection and two stream with bins with every other week colleen lion as well as a pilot area using St Paul s current seven sort system. Statistics show the most significant gains in recycling tonnages collected and in tonnages successfully processed where in the area that had weekly collection using bins and in the area that had biweekly collection using wheeled cants. This suggests that dements of convenience such as carts or weekly collection are what increase participation instead of being able to put recyclables into one container . Meanwhile Roseville residents seem cool to He idea of using a single stream system. In the 2002 survey, Roseville homeowners were asked if they would like to use a single stream system. Fifly — onepercentsaidyes , 49 percent said no The group that said yes was asked how much more per month they would be willing to pay to use a single stream program. Thirty nine percent said they would not be willing to pay more while 24 percent said they would pay $2 more a month and 19 percent said $1.
