How Long Does Cardboard Take to Decompose? A Practical Guide for Eco-Conscious Businesses
Cardboard decomposes within 2–3 months in compost but can persist up to 10 years in landfill due to limited oxygen and moisture. Moisture, temperature, coatings and board type strongly influence breakdown rates. Recycling extends fibre use for 5–7 cycles before composting or energy recovery becomes necessary. Corrugated boxes with FSC®‑certified kraft or uncoated surfaces decompose faster than laminated variants. Recycling yields roughly 70 % recovery in Europe, significantly reducing landfill methane and resource consumption.
