Stop Throwing Out Old Plastic Food Containers: 10 Brilliant Hacks to Use Them Around the House

Plastic food containers are everywhere in our kitchens. They’re handy for storing leftovers, packing lunches, or organizing small items. But what happens when these containers have outlived their original purpose or you no longer use them for food? Instead of tossing them into the trash and contributing to landfill waste, why not repurpose these plastic containers in clever and useful ways around your home?

Not only does this save money and reduce waste, but it can also help you get organized, solve storage problems, and even boost your DIY and gardening projects.

Below are 10 brilliant hacks to reuse old plastic food containers that you probably have lying around right now. Let’s dive in!


1. Seed Starters for Gardening

If you’re into gardening or want to start a small herb garden indoors, plastic food containers make excellent seed starters.

How to do it:

  • Clean your containers thoroughly to remove any food residue.

  • If your container has a lid, punch several small holes in the bottom to allow water drainage.

  • Fill the container with potting soil.

  • Plant seeds according to their depth requirements.

  • Use the lid as a mini greenhouse by leaving it slightly ajar or removing it once seedlings sprout.

  • Place the container in a sunny window sill.

Why this hack is brilliant:

These containers create a mini greenhouse effect that helps keep soil moist and warm, ideal for seed germination. Plus, the transparent plastic lets you watch root development. Once seedlings grow strong, transplant them outdoors or into larger pots.


2. DIY Drawer Organizers and Dividers

Why this hack is brilliant:

This method avoids buying expensive drawer organizers and repurposes materials you already have. Plus, it’s customizable to any drawer size and purpose.
