A GUIDE TO COMPOSTING: WHAT CAN I COMPOST (AND WHAT CAN’T I)

What is Composting?

Composting is the natural process of recycling organic material—like food scraps and yard waste—into a nutrient-rich soil amendment. This "black gold" enriches soil, reduces waste, and helps close the loop in the natural ecosystem.

What to Compost

Composting is easy when you know what materials can (and can’t) go into your compost pile. Here’s a quick guide:

Green Materials (Rich in Nitrogen)

These materials help create heat and fuel the decomposition process:

• Fruit and vegetable scraps (peels, cores, etc.)

• Coffee grounds and used tea bags

• Grass clippings

• Fresh plant trimmings

• Old flowers and houseplants

• Eggshells (rinsed)

Brown Materials (Rich in Carbon)

These materials add structure and help aerate the compost:

• Dried leaves

• Cardboard (non-waxy, torn into small pieces)

• Paper towels, napkins, or tissues (if free of chemicals or grease)

• Shredded paper (e.g., newspapers, non-glossy mail)

• Sawdust and untreated wood shavings

• Straw and hay

Optional Additions

• Hair and fur

• Small amounts of bread and grains (in moderation)

• Dryer lint (if fabrics are natural)

What NOT to Compost

These materials can attract pests, create odors, or introduce harmful chemicals into your compost:

• Meat, fish, or dairy products

• Greasy or oily foods

• Plastics or synthetic materials

• Diseased plants or invasive weeds

• Pet waste (from carnivorous animals like cats and dogs)

• Glossy paper or magazines

• Coal or charcoal ash

• Treated or painted wood
