Recycling In the City

I used to take advantage of curb side pickup. It was very convenient, but I decided to save some money and take my recyclables to one of the City's 26 drop off sites. I wouldn't be able to re-join the city curbside program even if I wanted to. They are maxed out on their participation. The city offers several zip codes discounted prices on curbside pickup, it is a cost shared with the refuse division. The website indicates that the maximum fund was reached.

Anyhow, I am very impressed with the amount and variety of items you can recycle.

In the last 6 months or so, they plastic recycling options have improved. Previously only 1's and 2's were accepted. Now 1's through 5's and 7's are acceptable. This make sorting much easier. Even though the majority of household items are 1's and 2's, 5's are becoming more and more prevalent.

Anyhow, I'm glad that I can recycle almost all of my plastics now. I wonder why the change was made. Is it a result of oil prices increasing, making recycling more economical? Is it a technology improvement? Is it supply/demand?
