| 摘要 |
A method of enhancing the compostability of waste products (i.e., products which have been discarded after use such as diapers) containing one or more propylene polymer materials by exposure to high-energy ionizing radiation in an oxidizing atmosphere, such as air, to improve the rate of the biological degradation of the propylene polymer material(s). The irradiated waste product is then contacted with living microorganisms in the presence of sufficient moisture for their growth and of an oxygen-containing gas to produce a useful compost humus.
