2012 Solid Waste Audit Results   1 comment

My project this summer (other than enjoying pregnancy and getting ready for baby) was to do a solid waste audit. Yes, that means that we saved all of our trash for a month, and then I sorted and weighed it. Like the energy audit we did last summer, this audit only measures waste generated in our household and not solid waste generated upstream, downstream, or outside of our control. By upstream waste I mean the solid waste generated in the creation of the products we use. By downstream waste I mean particulate or solid matter in wastewater. I’m not sure how much of the soap that goes down the drain flows through the wastewater treatment plant, gets consumed in the wastewater treatment plant, or gets disposed in the sludge. Solid waste outside of our control would be stuff like the asphalt that was scraped off our street before repaving. This audit also doesn’t take into account stuff that goes into the give-away pile, or stockpiles (plastic bags to be used for garbage, receipts tossed at the end of the year, saved magazines, etc.).

I was hopeful that this year would show improvement over 2006, when I last did a trash audit. I’ve started recording on the calendar from our trash company what weeks we take our bins to the curb, and we’re pretty regular. Almost exactly monthly we take out the recycling and the trash, and that schedule is determined by when the recycling bin is full usually. It’s pretty rare for the trash bin to be more than half full. Based on weight we recycle almost 90% of our trash (that’s skewed a bit by the density of the paper and glass jars in the recycling). Last year I think we only took out the green waste once, but this year it’s been quarterly as I rip out part of the lawn and throw that in the green waste instead of compost so that I’m not spreading my weed seeds.

There were a few major reductions in weight: newspaper, organics, and unrecycleable plastic. Newspaper is out of our control as that just means the Bee is smaller than it was 6 years ago. However, I’m very happy to know that our compost pile is diverting approximately 8 pounds of waste per month. Unrecycleable plastic also makes me feel good because I think that is an indication that the attention we pay to reducing packaging is paying off. We also had a couple significant increases in weight: glass and mixed paper. Glass: well, we are eating more jarred pickles now. We’ve got a good stockpile of jars in the pantry for food storage but we go through more pickle jars than there’s need/space to store them. And the mixed paper? Oops. When we moved we completely forgot to sign onto the “do not mail” registry at our current address. We’ll be doing that now.

Overall, though, I’m happy, we had a 30% reduction in solid waste weight from 2006. That puts us only 15% more than my 2001 audit results, which was just my one-person household. Wonder where we’ll stand in 2016 with kids in the family.
