I often use the recycling facilities at the city of River Falls Public Works facility on Benson Street, but my comments pertain to any recycling facility.
At the River Falls facility there are separate clearly labeled bins for paper and containers. It is depressing to see how many people don't seem to understand the difference, putting paper and other debris in with bottles and bottles in with paper.
There is also often a misunderstanding as to the types of materials -- especially plastics -- that can be recycled. Mixing recyclable materials with non recyclable material in these bins can contaminate the entire contents, negating the efforts of more conscientious recyclers.
The same criticism can be leveled at those who leave plastic bags by the "no plastic bags" sign at the River Falls city compost site.
Be aware of what you are doing and the consequences. For those who don't know the difference between paper and bottles, I know some kindergarteners who can help you.
For those wishing to upgrade their knowledge of the realities of recycling, I highly recommend the excellent book “Can I Recycle This?” by Jennie Romer available at local libraries.
