You can also reuse some cooking oils by straining and storing them. For large amounts, check if your community has special disposal options.

• Let fats cool and harden before disposal
• Scrape solid fats into the trash
• Use a sealed container for liquid oils
• Find local recycling programs for cooking oils

Reducing Kitchen Fat Waste

Reducing fat waste helps both your kitchen and the environment. Use less oil when cooking. Try baking, steaming, or grilling instead of frying.

Save leftover oils for another meal if you can. Clean pans with paper towels to remove grease before washing.

• Cook with less oil and fat
• Choose healthier cooking methods
• Reuse cooking oils safely
• Clean pans before washing to reduce grease

Kitchen Paper And Packaging

Many kitchen papers and packaging materials can be composted. Composting helps reduce waste and enrich soil. It is important to know which items are compostable.

This guide focuses on paper towels, napkins, cardboard, and paper packaging from the kitchen. It also explains what to avoid.

Compostable Paper Towels And Napkins

Paper towels and napkins can be composted if they are clean or lightly soiled. They break down quickly and add carbon to compost.

Do not compost paper towels or napkins with chemical cleaners or grease. Use only those from food cleanup or drying hands.

• Use unprinted or recycled paper towels
• Compost napkins with food stains only
• Avoid towels with bleach or chemicals

Cardboard And Paper Packaging

Cardboard and paper packaging can be composted if they are free of plastic or wax coatings. Tear them into small pieces before adding to compost.

Pizza boxes, paper bags, and egg cartons usually compost well. Remove stickers or tape if possible to avoid contamination.

• Break down cardboard into small pieces
• Only compost paper without plastic lining
• Remove any non-paper parts like tape

Avoiding Contaminated Items

Some paper products have coatings or food residues that stop them from composting. Avoid these to keep compost healthy.

Do not compost waxed paper, glossy packaging, or items with heavy grease. These can harm the compost process.

• Do not compost waxed or glossy paper
