I have the type of waste baskets that are made to hold plastic grocery bags as a liner. I haven't bought can liners in decades. Even if they're ratty, I double them up and put a few sheets of newsprint in the bottom to prevent puntures and absorb any moisture. Because they're free, when there's something particularly messy, like with food prep, it can get tied off and taken straight out to the trash.

I always look for ways to recycle whenever possible. My favorite "invention" is when I trim the top of an 18 egg foam egg carton (the middle ridges on both sides so you get two sets) and place them upside down inside of the small plastic bins packs of mushrooms come in. This makes a tray to place your sink sponge in. It allows the air to circulate so it dries quicker and cleaner, keeps the counter dry, and when it starts to get scummy and a rinse doesn't cure it, you throw it into the recycle bin and make another. There's at least one on and/or under every sink in the house.

Reduce, re-use, recycle, reclaim, repurpose.
