Should oil be poured down the kitchen sink? My mother-in-law says yes but I’m not so sure

✅ Recycle It

• Many cities have drop-off locations for used cooking oil.
• Some restaurants and recycling centers accept it for biodiesel production.

✅ Compost Small Amounts (Plant-Based Oils Only)

• Mix small quantities with absorbent materials (cat litter, sawdust).
• Add to compost bins—avoid large amounts to prevent odor.

The Bottom Line

Disposing of cooking oil the right way keeps your pipes clear, saves money, and protects wildlife. A little effort today prevents big problems tomorrow—for you and the planet.
