DEGRADATION CONTROL OF ENVIRONMENTALLY DEGRADABLE DISPOSABLE MATERIALS |
摘要 |
The present invention is directed to a method for reducing waste accumulation by using an environmentally degradable disposable material. The disposable material, which includes a hydroxycarboxylic acid-containing polymer, degrades hydrolytically during operative and disposal stages in a controlled manner such that the disposal degradation rate of the material is accelerated relative to the operative degradation rate of the material.
