All grades are tested for their intrinsic viscosities as guidance on the molecular weight of the synthesized polymer. This is very important in biomedical applications, as it ensures the rate of resorption in the body. When the polymer is exposed to aqueous media or tissue, the ester linkages of the polymer react with the absorbed water through a hydrolysis reaction. Over time, the long polymer chains are broken into shorter ones to form water-soluble fragments. Eventually, the water-soluble fragments diffuse away from the initial polymer structure and finally hydrolyze to glycolic and lactic acid for metabolism by the liver.
For instance, the PLA cup uses less fossil fuel than the PP cup; however, the respiratory effects caused by the inorganics of the PE-coated cardboard cup remain the highest. The size of the event also has an effect on the eco-efficiency of the cups. The PC cup appears to have the lowest environment impact when used for a small event. This is due to the reusable nature of PC, which can be washed by hand, meaning that less water and detergent is used in the cleaning process. 15 (a) Eco-indicator values for the usage of cups at small-scale indoor and large-scale outdoor events.
