Bacon grease should not be poured down the sink, but it can be saved and used in your next recipe.

Peelings from carrots, potatoes, and other vegetables can end up down the drain, but that’s about the worst place you can put them. This organic waste will cause backups and clogged pipes faster than you can say “compost pile.”
Speaking of which, a compost pile or organic waste processor This is precisely where these materials should go. Here is how to start a compost pile if you are new to the game.
3. Oil-based foods: salad dressing, mayonnaise, sauces and marinades
Avoid throwing large amounts of mayonnaise or salad dressing down the kitchen drain.
The same goes for fatty foods including salad dressings, mayonnaise, marinades, etc. A small mayonnaise stain may not be a problem, but throwing out an entire bottle of outdated balsamic vinaigrette or teriyaki marinade could cause problems.
Foods with a high oil content cannot be composted and should be thrown in the trash.
4. Coffee grounds
Coffee grounds can be composted but they should not go down the drain.
If you brew coffee every morning, throwing away the grounds is just part of the routine. Coffee grounds can be composted, but they should not be flushed down the drain. Over time, coffee grounds will build up in the pipes and cause a backup.

5. Flour
Extra flour should be composted or thrown away.

If you have flour left over from a baking project or recipe, you should compost it or throw it away.
6. Dirt and earth
Fight the urge to throw excess potting soil down the kitchen drain.
I am certainly guilty of this one. The kitchen sink seems perfect for transferring a houseplant from one pot to another, but soil and other debris can easily clog your drain.
If you can do this without leaving more than a few granules in the sink, you’ll probably be fine. If it’s a lot of repotting, it would be wise to take the project outside.
7. Rice and pasta
Whether cooked or raw, rice has no place in your pipes. Compost it instead.
Unless you have a trash can, food scraps should not be flushed down the drain. Rice and small pastas are especially tricky because they can slip past your pipe guard and into pipes they shouldn’t be in.
To avoid a starch-based clog, throw leftover grains and pasta into the compost pile or the trash if you don’t compost.
8. Paper products
Paper products, no matter how thin, do not end up in the kitchen drain.
No paper product should be flushed down the drain, even if it is made from a thin compostable material. Some kitchen products, like plates, bowls and napkins, can be composted, but check them carefully before adding them to your kitchen pile or smart kitchen bin. Otherwise, they should be thrown away.
9. Paint
Oil paint is the worst thing you can pour down the kitchen sink. Try mixing it with cat litter until it dries before throwing it away.
I’ve been guilty of this too, but it’s time to break the habit. Because the paint is liquid, it may seem like a candidate for the kitchen sink, but that’s not the case. The paint sticks to the pipes; if it dries, it becomes a serious plumbing problem.
A great tip for getting rid of old paint: cat litter. Mix some litter with the old paint can until it hardens, then throw it in the trash. Check with your local sanitation department for certified disposal facilities for oil-based paints.
