I have lots of egg cartons properly stacked up in my storage. I regularly use some of them as a seed starter. But I can not use them all up. This is the work around I came up with about how to use the cartons faster.
Step 1: Materials
We need egg cartons that you desperately want to throw away.
Step 2: Shred and Soak
Shred the egg cartons with hand and soak them up. Soaking them properly takes around overnight.
Step 3: Blend
Drain the excess water and blend then in a home grinder. Add water if the grinder seems to jam.
Take out the pulp and make small brickets by hand. I did it by hand. You can use some shaper that make them look good.
Make sure NOT to squeeze hard as the residual water makes space for air when it dries up.
Air dry the brickets. Total drying takes around 3 days in an Indian summer.
Step 4: Done
After total drying you can use them to start a fire. They catch fire easily and a single bricket burns for around 15 minutes, much time to start a good fire.
