• • Cornell University and AMC Labs confirm cotton denim biodegrades in compost. They find polyester blends do not. [Source: Cotton Incorporated researchers]

• • The Guardian (2024) explains that only 100% natural fibers—pure cotton or linen that is untreated, unbleached, and unblended—compost safely at home. Chemical finishes and plastics make composting hard. Source: The Guardian

• • Reddit community r/ZeroWaste shows mixed results. Members see that home composting success varies, especially with blends or treated fabrics. [Source: Reddit r/ZeroWaste discussions]

Water Use

Cotton farming needs much water. Composting cotton fabric does not use extra water. Microbial action in compost calls for some moisture. Composted soil holds water well. It cuts irrigation needs (Cotton Incorporated).

Expert Tip:
• Use composted cotton scraps on your garden soil. This act boosts water retention and lowers irrigation needs (Steven Pires, Cotton Incorporated).

Carbon Emissions

Composting cotton fabric keeps textiles out of landfills. Landfills release methane, a powerful greenhouse gas. When you compost, you lower methane emissions. Compost on soil makes a carbon sink. It helps pull CO2 from the air (Cotton Incorporated).

Expert Tip:
• Choose composting over landfilling natural fiber textiles. This choice cuts methane and supports carbon storage.

Chemical Inputs

Chemicals such as dyes, anti-creasing agents, and synthetic threads add trouble. They slow decomposition and may harm the compost (Stephanie Devine, The Very Good Bra; Courtney Holm, Circular Sourcing).

Expert Tips:
• Compost only natural cotton fabrics that are untreated, unbleached, and undyed.
• Remove extra parts such as zippers, buttons, elastics, or synthetic threads.
• If you doubt the treatment used, avoid home composting. Look for industrial compost options that control chemicals.

Recycling: Cotton Fabric Composting Best Practices

• Cut fabrics into small bits. This pace helps microbes work fast (The Guardian).
• Remove non-compost parts from your fabric.
• Compost certified organic cotton and linen when you can.
• Use worm farms for safer home composting. Worms help filter out contaminants (The Guardian).
• Support textile composting standards like Australia’s coming protocol (Stephanie Devine).

❓ FAQ

Q: Can I compost my old cotton T-shirts at home?

A: Yes, if your T-shirts are 100% natural cotton. They must be untreated, unbleached, and free of dyes, elastics, zippers, or buttons. Cut them into small pieces. Remove non-organic parts before adding to your compost. Otherwise, try industrial composting or textile recycling.
