One of the best ways to get a handle on your trash output is by channeling your inner raccoon.
Yup, I’m talking about digging into your trash can and finding out what’s really going on there with a trash audit.
It can be a pretty gross undertaking, but honestly: what can motivate you to reduce your waste production than the prospect of digging through it a second time?
What is a trash audit?
A trash audit is essentially a study of what kind of trash you make. This is obviously incredibly helpful for someone interested in the zero waste movement, as it sheds light on problem areas. But don’t be too hard on yourself – you’ll always have some trash because we don’t live in a society with a circular economy. If you want to learn more about that, check out my post on why zero waste isn’t zero.
Honestly, I think a lot of people will be shocked at the amount of trash they create absolutely unconsciously every day.
Think fast: what’s in your trash can right now?
You probably can’t answer that question, can you? That’s kind of the point. Once you get a full view of what you’re actually tossing, it’ll be far easier to pinpoint effective lifestyle changes to make in order to reduce waste.
The good news, though, is that once you do a trash audit you’ll be set for quite some time. Don’t think this is something you need to do weekly, or even monthly (I mean, unless you want to and then go for it!). I usually conduct a trash audit when I feel myself slipping – when the trash starts piling up a little faster and my purchases get sloppier.
What’s the procedure?
Now that you can answer the questions ‘what is a trash audit?’ you can get started – just start digging through your trash. Wait… you wanted more direction than that?
Oh, fine – here you go:
Choose a length of time
For the purpose of this experiment, start with a clean slate: remove all trash from the house day 1 and go about your habits normally for seven days. On the last day, get measuring. A week is an excellent time frame. It’s not so much time that you get bogged down in an insurmountable pile of garbage, but it’s also long enough that you should get a decent slice of what your actual waste output is like.
Choose the way you’re going to analyze your trash
Decide on a couple of general guidelines before you begin.
- Will you note every piece of trash as it goes into the bin or do one larger tally at the end of the day/week?
- Will you list specifics or just general groups of items?
- What will you be measuring this against?
Weigh your trash – if you want
The most accurate way is to measure by weight. While volume measurements work, I prefer weight for more accurate tracking. A standing scale will work if you hold your trash and subtract your weight, but for convenience sake, a hanging scale is really helpful. I have this one that I used for weighing bags before travel, but now i just stick a bag on there, toss in my trash, and weigh it to see how much I’ve created.
A kitchen scale would also work for smaller amounts of trash.
You can also measure by volume (number of bags filled) or by numbers (ie. number of produce stickers) but these options are less precise and more time-consuming. Still, they’re helpful and don’t require a scale
General tips for a useful trash audit
- start with just landfill trash. This means – ideally – having recycling and composting options set up in your home. Compost is a no-brainer since you’ll eliminate all the ickiness of trash; I’m able to do a trash audit simply because I don’t have to worry about sticking my fingers into a week-old apple core. (If you absolutely can’t compost, at least create a wet and dry trash.) Recycling should also be separated immediately just because there’s a chance it’ll get thrown away if it’s not sorted properly. I realize not everyone has time to dig around in their trash, especially if you create more than we do.
- take notes on what you find. In my e-book, Minimize Your Trash, I have a super-simple worksheet that lets you record your findings and lays out exactly what you need to work on. Essentially, it has a spot for measuring how much trash you produced (and a spot for comparing your change later) as well as notes on what you see most often and a goal-setting area.
My trash audit, February 2018
I was actually pretty proud of my husband and I when I looked at what we’d produced! This is our landfill-bound trash production for one month. (There are a few things in there that can be recycled or composted, so I put them to the side. My husband isn’t always sure, so I tell him to just toss it in and I’ll figure it out.)
Our trashcan is a small metal one meant for a bathroom, I think. I’d say we fill it about every month, but when I remove the items able to be recycled, composted, or reused, that stretches to about seven or eight weeks. For example, three of those plastic bags I’ll save to be reused as storage or mini greenhouse toppers.
Our biggest trash producer by far is receipts. The places that we typically shop (Fresh Thyme and Big Lots for groceries) do not provide an option for not getting receipts. And because they’re not the plain matte kind I don’t want to risk putting them in the recycling stream and potentially contaminating it (source). So to the trash they go.
Other than that, and the ubiquitous produce stickers, I think our household is doing a great job, especially because my husband is not consciously zero waste. (Read more about going zero waste with someone who doesn’t care here.)
Notes on what’s in my trash can
- compost: we have a three-gallon bin I bought from IKEA. It’s about 1/2 way filled for about two weeks worth of organic waste. We then take it out to our tumbler in the backyard. To read more about our composting system, check out this
- recycling: our city has an amazing recycling program where we can throw everything in together and have it recycled with no issue. We have a small blue bin and I’d estimate it was filled about halfway with recycling, mostly paper, a styrofoam cup, and a few plastic containers.
- This does not include all the trash we produced. For example, we received a package with bubble wrap – we’ll reuse the cardboard box and bubble wrap for sending a package soon. Items that have been repurposed I don’t count until they actually head to the landfill.
How do I make changes after a trash audit?
That’s where Minimize Your Trash comes in. I talk specific, targeted strategies about how to reduce your landfill-bound waste by 50% in just four weeks. These are all the habits I learned and implemented for my husband and I to produce relatively little trash (even though my husband is a self-avowed ‘not zero waste person’).
If you’re interested in learning more hands-on learning about a trash audit and to see exactly the trash I made this month, I’ll be hosting a webinar next Sunday which you can sign up for below. I’ll take you through my trash, talk about my future goals, and leave you with three practical strategies for drastically reducing your landfill-bound trash. Hope to see you there!
Have you ever done a trash audit? Would you consider doing one now you’ve seen how it works?
