As a tenant in a seven unit converted Victorian close to the University, I oversee our recycling efforts. We would not fall under this proposed ordinance because the total waste generated by the seven small apartments does not amount to more than one cubic yard per week.
Nevertheless, I think my observations might be useful, and would scale up to large complexes.
Of the one cubic yard per week, we sometimes fill one blue bin by week's end but often fall short of that. The garbage cans are picked up by a private service, the four of them together accounting for the other half a cubic yard. If you concluded from this that the recyclables to trash ratio is 50:50 you would be mistaken. That's the compliance ratio, not the actual ratio. Often, there are more recyclables in the garbage cans than in the blue bin. If everybody cooperated, our ratio could be 70:30 in favor of recyclables.
What I've learned from direct inspection is that most of what is thrown into the garbage cans is recyclable packaging waste. Sometimes I pull this out of the cans, making sure it contains no food, and put it in the blue recycling bin, but I cease such efforts when garbage and bathroom wastes are mixed in, which quite often is the case.
If all the tenants were conscientious, there would be more weeks when one blue bin would be insufficient without diligent compaction.
The solution, as I see it, would scale up to businesses and multiple family complexes of any size. The solution is separation and compaction of recyclables at the time they are thrown away within the household or place of business.
Separation alone is as easy as non separation. A flick of the wrist isn't any more trouble if aimed at the indoor recycling container instead of the garbage container. Separation of recyclables depends on awareness and conscientiousness, but it doesn't require any more trouble. If people separated their recyclables from their other trash when they threw things away, our garbage cans would seldom be full and our blue bin would always fill up by Sunday.
Compaction, however, does take effort. Nobody in the seven units has a trash compactor and nobody does this by hand and foot but me. I am the defacto trash compactor for all seven compartments. Several times a week I inspect the blue bin to make sure all items therein are compliant (the most frequent violation is solid foam packing materials concealed within discarded packing boxes).
While conducting a compliance inspection I compact boxes, plastic containers, and anything else that is essentially an enclosure of air. I have two poles for pounding down the waste to make more room. I will fish things out, like plastic bottles and aluminum cans, toss them to the asphalt and stomp them flat. I tear boxes into sheets of cardboard, and line the inside circumference of the blue bin with these sheets so they displace minimal volume. This oversight can be a bit of work, sometimes, work that I wish the tenants performed when they separated and crushed items within the household, in the act of throwing them away.
I'm telling this personal anecdote to make the point that compliance begins at the moment packaging becomes trash, inside a household or business. Turning the screw on landlords isn't going to help much with meeting the city's recycling goals. I realize that in America, managing by force and coercion has a long tradition despite the fact that it seldom works.
What the city needs to do is supply tenants in multiple family complexes with recycling collection containers for use within households, and have a similar policy of facilitation for businesses. These indoor containers should use the same traditional blue with the recycling logo. Families with children should be given coloring books for kids illustrating the recycling habit, the bins already colored blue. Propagandizing kids is a great way to control adults, as kids can be the conscience of the family.
Complexes and businesses needing compactors for efficient use of blue bin volume should be aided by the city in some way.
In summary, the take home lesson from my experience as a recycling manager in a small apartment building is that recycling begins in the home and the workplace. Make separation and compaction a habit by providing the tools.
