Food waste is partly a behavioral issue and partly an informational one. Here’s a thought.

Walk through most kitchens and you’ll find the same kinda thing.

Half-used electrolyte powder; a specialty sauce opened with enthusiasm last year, and then forgotten.

Wellness snacks purchased aspirationally and consumed … um, sporadically.

Those expiry dates sneak up on you.

We talk about sustainability constantly, and yet most CPG packaging still optimizes for shelf life, more than human follow-through.

Importantly, retail data shows that repeat product sales are driven from completion.

Buyers need to finish what they started to buy again, and too many are not.

There is an unmet need hiding as a result: help me completely enjoy this stuff, not just buy and nurse it until most ends up in the garbage. Then I probably won’t buy it again.

Imagine Consumption-Signaling Packaging.

Not an app or a QR code, or anything fancy. A simple mechanical or chemical cue that changes after opening, like the fading bristles on some toothbrushes or the time-testing indicators (TTIs) used on vaccines or seafood.

A visual indicator that says, “Hey bub, you opened me sixty days ago,” or portioning that nudges completion instead of endless (and often futile) preservation.

Before we romanticize this idea too much, it deserves balance.

I actually like products to be available. There is a reason we buy Costco-sized staples.

In my house, we burn through cinnamon and cumin quickly. Other spices linger for untold years.

After college, my roommate Steve and I once discovered a tub of yogurt in our fridge that had technically expired three years earlier. We made a huge production of the opening.

To our shock and disappointment, it looked and smelled totally fine.

I’ve since consumed kefir a month past its date with no issue. Expiry is weirdly imprecise.

It nearly puts me over the edge when someone throws out a carton of perfectly good milk just because the best-before date has arrived.

I’ve seen ad campaigns saying expiry dates “mean it” and anti-food waste campaigns suggesting the polar opposite. No wonder we’re all so confused.

Guilt plus uncertainty leads to postponement. And then postponement often leads to waste.

Brands that help consumers complete a product could earn repeat purchase faster than those maximizing remaining grams.

The challenge is right-sizing. Use it before you lose it to the Father Time of perishables.

Which products benefit from longevity, and which from momentum of habitual consumption?

That distinction could be the real innovation brief.

What’s your take?

Are you a perpetual food archivist, or do you turf things the instant they expire?
