What does it mean to be certified industrially compostable?

Most BioPak products are certified industrially compostable to the Australian AS4736 compost standard. AS4736 requires that the product disintegrates after 12-weeks in industrial compost conditions and completely biodegrades after six months. That means that 90 percent or more of the material will have been converted to CO2 and the remaining share is converted into water and biomass. AS4736 also requires that the quality of the compost is not hindered by the products and is safe to be applied to land.
