Is bioWRAP® shrink wrap really biodegradable?

“Yes, in landfill conditions. In independent testing to ASTM D5511 — the standard method for anaerobic biodegradation under high-solids conditions that simulate a biologically active landfill — bioWRAP® reached 78.8% biodegradation in 1,067 days. Actual rates in a landfill vary with moisture, temperature and microbial activity. bioWRAP® is not compostable and is not designed to break down in open air.”
