How to Perform a Trash Audit – Day 31 of the Zero Waste Challenge

How to Perform a Trash Audit – Day 31 of the Zero Waste Challenge

31 Day Zero Waste Challenge

Last Updated on July 9, 2020

Waste audits are the ticket to a successful zero waste journey.

After all, how can you reduce your trash if you don’t know what you’re throwing away?

It’s day 31 of the zero waste challenge. Can you believe it?

How to Perform a Trash Audit - Day 31 of the Zero Waste Challenge from www.goingzerowaste.com #zerowaste #ecofriendly #gogreen #sustainable #zerowastechallenge #challenge #sustainablelivingchallenge #wasteaudit #trashaudit

It’s the final day of the challenge, and I’m already thinking about next year… like what if the challenge were an app and you got points!?

And, at the end of the challenge if you got x number of points you won a prize!?

What do you think? Too much? / Do you know/are you an app developer?

The beginning of the challenge is focused on simple swaps like bringing your own water bottle and bags to the grocery store.

The second phase of the challenge is focused on lifestyle changes like learning to make your own snacks, decluttering your life the zero waste way, and conserving natural resources.

Now, we’re into the third phase of the challenge. The activism phase.

The phase where you get to get a little outside of yourself and work on bringing change at a whole new level.

Today I’m challenging you to perform a waste audit. And, once you’ve mastered it, call up your friends and teach them how to do one too!

the problem:

if you don’t know what you’re throwing away, it will be difficult to figure out where you can improve and reduce your waste.

See, I don’t believe that you have to be perfect to make a difference, but if you can identify a few of the major areas you’re creating waste – you can have a massive impact with just a few small changes.

For instance, in your trash can, you find a bunch of paper towels, tetrapaks of nut milk, and food scraps.

Well, with three small changes like breaking up with paper towels, buying cashews from the bulk bins and making your own nut milk, and composting – you’ve eliminated 80% of your house hold waste.

All it took was three small changes!

But, you will never know what your top three changes are without performing a waste audit.

the solution:

All you need is a couple of minutes, a little commitment, and a clipboard or notebook. 

1. get to know your trash:

Dump all of your trash and recycling out and go through it. For each item you find write it on the clipboard.

For each recurring item add a tally mark.

2. organize by tally mark:

This will give you a nice visual road map on how to reduce your trash. You can figure out where you can make the biggest impact. 

I love it when people just want to dive into zero waste, 100%, right away! But, it’s hard. There’s a lot of changes that you’ll be making, and it’s important to avoid burn out because it is IMPOSSIBLE to go zero waste overnight. 

It’s impossible to do it in a week or even a month! I STILL have products from my PZW days even three years later. 

3. make some changes:

Now, you can start looking for easy zero waste swaps. Always start with the things you’re throwing away most for two reasons.

  1. You’ll have make the biggest impact.

  2. You’re going to notice an immediate difference. And, humans love instant gratification. 

I’d want to tackle the first five right off the bat. 

PAPER TOWELS: The first thing I would do is start phasing out paper towels for reusable dish towels. Get my six tips for ditching paper towels

FOOD SCRAPS: Then I’d start composting. Composting is one of the best things you can do for the environment! Whether you’re in an apartment or have a backyard, there are a lot of options for you to explore.

Before you even get to composting, maybe you can eat those scraps! Check out 8 recipes for using up your food scraps, and my guide to storing your produce without plastic.  

Q-TIPS: You can buy q-tips with paper bases instead of plastic ones and then throw them in your compost! 

JELLO: As far as jello cups go, you could make a big batch of jello from the box. You can recycle or compost the box, and then divide the homemade jello up into individual containers like these*.

Not all schools allow glass in lunch boxes, so a stainless one* might be a good option instead of plastic. 

COFFEE CUPS: Avoiding coffee cups is pretty easy! Check out all my tips in this post about The Big Four

4. repeat: 

Your trash probably changes from week to week. Keep checking in on your trash and recycling to see where you can easily improve. I recommend doing this once every couple of months.

Obviously, there will always be some unavoidable trash. The first thing that pops into my mind is medication. 

I get a lot of people emailing me asking how to handle the trash with their medication…. and my answer is always the same. 

YOUR HEALTH COMES FIRST!!! 

I will scream it from the rafters. Do NOT let any other person tell you differently. I’ve seen some other prominent zero wasters say some scary things….

So, one more time for the people in the back, ***your health always comes first!*** 

The fact of the matter is that we lived in a flawed system. For more information read this post about the true meaning of zero waste.

It’s so long, it got it’s own audio file so you can listen while on the go! 

Don’t look at what you can’t do, always look at what you CAN do.

There’s so many things you can do that don’t involve medication, and seriously, if you changed everything in your life except medication, that’s freaking amazing!! 

Celebrate! Cause you’re awesome. 🙂 

take the challenge!

I can’t believe this is my final challenge for you this year. I’m getting a little emotional.

I’m challenging you to perform a waste audit this week, and swap out your most common items for zero waste alternatives (if there is one).

Most likely there is. If you need any inspiration check out my post The Ultimate List of Zero Waste Swaps.


Did I do a good job covering the zero waste basics?

How do you feel now that you’ve gone through 31 days of challenges? Is your trash can lighter? Your recycling bin less full? I would love to know how the challenge worked out for you! Let me know in the comments below!

want more?

Just starting out? Have 1,000 burning questions!?

Get access to my private Facebook group, where I’ll be hosting weekly lives throughout the challenge and I answer all of your most pressing questions.

PLUS! I’ll be sending out a brand new e-book at the end of the challenge called the Game On Handbook which is all about individual ways to fight climate change.

You don’t want to miss it.

miss a day?

  1. This was a fantastic challenge and I really enjoyed reading all of the posts. A lot of these I was already doing but it was nice to have affirmation and I still learned a lot on each topic. I think a challenge with an app and points next year would be awesome (and not too much at all)! Thank you for doing this for all of us!

  2. I agree with Stephanie… Love an app with points. There’s an app out there (plant nanny?) to remind folks to drink more water and the plant grows (or dies) people actually love this thing. A fun way would be to give points for action items and then visualize a location going from dirty to clean.

    I have dived in 85% on this challenge (still need hubby and kids to make up the remaining 15%). This weeks trash collection was half of the collection prior to starting (which even included a whole house purge of junk!!). Teaching the kids to refuse has been great!!! I loved the portable zero waste car kit! Switched over to napkins! I have hidden what remains of the paper towels for use with elder dog accidents and pulled out the sewing machine to make kitchen rags out of some junk fabrics I can’t recycle. Worm composter in house is going greAt! Found place to use jars for bulk. Struggling to find a place for deli meat/cheese and using my own containers. Most won’t accept citing health codes. Found local milkmanthat delivers reusable containers. Not perfect… but a lot better!!!

  3. Garbage is the indispensable bitter truth of daily life. When you cook, eat, clean your house, you discover a wholesome collection of trouble making rubbish. But the good news is, this problem can be addressed by simply hiring a skip bin.

  4. Hi Kathryn,
    I just discovered your blog today and it is funny to read about your idea of an app. Because in fact, I am working on exactly that! For my master thesis (I study Industrial Design at the Technical University of Eindhoven), I have developed a concept for an app. Here, people are can be the hero on their own Zero Waste Journey. I would like you to get in contact with you and see what your opinion is about the app. Please look for my Instagram @wasteherojourney (or my personal account @shannadelang).
    I hope to hear from you!
