We've just started replacing common plastic kitchen items, especially single-use disposable items, with eco-friendly and reusable alternatives. Here are a few of our favorites.
Produce Bags - there are a lot of reusable produce bags out there (I happened to buy these on Amazon and love them). I keep a bunch of them stashed in my reusable grocery bags in my car so they're there anytime I go shopping. They're super light, so they don't add to the produce weight, and cashiers can even scan through the mesh.
I'm a big fan of this Bee's Wrap, a natural alternative to plastic wrap. You can also make your own! I searched online for a tutorial, ordered some natural beeswax pellets, and grabbed some fabric I had in the house for a relatively simple DIY.
