How to Upcycle Cigarette Butts into Low-Cost Insulation


Cigarette butts are one of the most littered items worldwide, with an estimated 4.5 trillion discarded annually. Most contain plastic filters that can persist in the environment for up to 10 years. Upcycling cigarette butts into insulation presents an eco-friendly solution to reduce this waste, while creating a useful product. In this article, I’ll walk through the step-by-step process to turn cigarette butts into low-cost insulation for your home.

Gathering Cigarette Butt Materials

The first step is gathering a sufficient quantity of used cigarette butts. Here are some tips:

  • Ask friends, family, neighbors to collect and donate their cigarette butts. Make it a community effort.
  • Contact local bars, restaurants, or other businesses that have outdoor ashtrays to collect their discarded butts on a regular basis.
  • Organize a cigarette butt drive or collection event to engage the broader community. Publicize through social media and flyers.
  • Be sure to wear gloves when handling cigarette butts to avoid nicotine absorption through skin.

Aim to collect at least 1-2 pounds of butts, as insulation requires dense packing of materials. The more you can gather, the better.

Cleaning and Preparing the Cigarette Butts

Once you’ve gathered enough cigarette butts, you’ll need to clean and prepare them for insulation:

  • Manually remove any loose tobacco, paper, or other debris from the cigarette filters.
  • Next, wash the butts thoroughly with hot water and mild detergent to remove residues.
  • Allow the washed butts to fully air dry before the next step. Spread them out on towels or trays.
  • Then, use scissors to cut the dried butts into smaller pieces, about 1⁄4-1⁄2 inch in size. This increases their insulation capacity.

The cigarette pieces are now ready to be upcycled into insulation!

Creating the Insulation

To transform the cleaned cigarette butt pieces into insulation:

  • Obtain recycled cardboard boxes or paper bags. Cut them into strips approximately 1 inch wide.
  • Mix the cut paper with the cut cigarette pieces in a large container. The exact ratio can vary, but a 1:1 ratio is a good starting point.
  • Add borax – about 2-4 tablespoons per pound of material. Borax helps repel insects and acts as a flame retardant.
  • Spray the mixture lightly with water to dampen. This helps the materials stick together.
  • Pack the damp mixture tightly into cardboard tubes, fabric pouches, or other vessels. Pack down firmly.
  • Let dry fully before using your new insulation! The borax helps accelerate drying time.

Your upcycled cigarette butt insulation is now ready to use for craft projects, framing walls, or even stuffing plush toys. Get creative!

Using Cigarette Butt Insulation

Here are some ways to utilize your eco-friendly cigarette butt insulation:

  • Stuff plush toys like dolls or children’s craft animals. It provides a light, fluffy filling.
  • Use it for sound dampening by lining interior walls or sound equipment.
  • Insulate bee hives by tightly packing the tubes where bees will form honeycombs. This helps maintain stable hive temperatures.
  • Frame small sheds, tiny homes, or other small structures by packing between wall studs.
  • Craft decorative throw pillows filled with the insulation and covered in fabric.

The insulation won’t be as lofty or flexible as traditional fiberglass, but works well for many purposes. Continue experimenting with ratios and materials to customize performance.


Upcycling cigarette butts into insulation offers an innovative way to reduce waste while creating a practical product for your home or hobbies.
