My Zero Waste Guide to Buying Bulk (Baby Got Bulk)

Trying to adopt the zero waste lifestyle (or just reduce your waste) and buy your food in bulk?

I’ve worked at a natural foods store for over six years and we have a HUGE bulk section. I have done everything from stocking bulk, cleaning bulk (so much cleaning), to ringing it all up. I know all the in’s and out’s of what goes on BTS (cool lingo for behind the scenes). So today I’m here to pass down my zero waste knowledge!

You will learn all about TARE weights, the different types of bluk + how to be prepared!

Let’s get a few things sorted first. There are multiple types of bulk available and this is not the same thing as a Costco type of bulk where buying in large quantities of something like 100 boxes of cheerios.

I’m talking about the bins full of oats, nuts, rice, and seeds. You can buy as little or as much as you like and are typically charged by the pound. Buying your food in bulk is one of the best ways to reduce your waste! You eliminate packaging by just buying the product and putting it in your own container saving you time and money in the long run!

Here is my complete guide on how to shop bulk!

Be prepared:

Buying bulk is all about being organized and prepared.

Heres what you need:

STOP!

Before you do anything, make sure you pre-weigh your containers!!  Cashiers cannot magically know the weight of the product minus the jar. This is super important in order to avoid the cashier pouring out the item into a plastic bag. This completely defeats the purpose of buying in bulk! So again, weigh all of your containers!

Some stores do this differently. Head on over to CS (cool grocery store lingo for Customer Service) and ask them how their day is going. Then ask them where you can weigh your containers.

Know they type of bulk you are getting.

Lets talk about dry bulk:

For containers you can go with metal, glass, or plastic containers, and even cloth bags. Keep in mind for items like sugar and flour you are better off bringing a jar type container to store them in. I got sugar in a cloth bag once and it got wet on the way home and it was a huge mess!

Cloth bags work great for beans, rice, granola, nuts, and seeds.

Liquid bulk:

For honeys, oils, and vinegars I stick with glass jars or other old jars I cleaned. 

Tip: When reusing old jars Sharpie out the bar code vertically not horizontally. This way you won’t get charged for the same thing by accident. Typically the scale is the same as the scanner so you don’t want the scanner to ring up your empty jar!

Cold bulk:

My area doesn’t have a ton of cold bulk options and one of the only options I see is bulk tofu. I’ve also seen fresh made pasta and both of these things would bring a sealed container for transportation to avoid spilling!

The Why?

This sounds like a little bit of work right? Well lets talk about the why behind buying in bulk

Lets talk about TARE

What the heck is a TARE weight?

The difference in buying bulk vs packaged is you are charged by the weight of the product instead of individually. So you want to make sure you are not being charged for the container you are using, that would be a lot of additional cost! Grocery stores have a few different ways of handling this but heres how I recommend you go about it. 

  • Have all you jars clean, empty and ready to be weighed.
  • Bring a grease pencil or a Sharpe so you can mark the weight on the jars
  • Sharpe over any old barcodes if you are using a recycled container (super important step so you aren’t charged for the wrong item)
  • Make sure you get the right weight weather it be ounces or pounds, know how its rang up!

Okay so jars are weighed and marked now youre ready to fill them with some bulk!

*Be mindful when filling that things can come out fast! I do a pumping motions for the pull bins to avoid over filling and spilling bulk all over the place!

Each store is different so if you have any questions on how to do this at your particular grocery store, ask someone that works there! They know how it works at there store best!

At Checkout:

Having all the weights of the containers clearly labeled and the PLU’s of the product ready to go is super important when checking out. Make sure you are paying attention to what you are being charged for as items are ringing up (cashiers can make mistakes).

Be friendly, patient, and helpful to your cashier! Buying bulk in your own container takes more time to ring up than packaged goods with an easy barcode!
