Background
As a famous traditional Chinese medicine, donkey-hide gelatin is prepared by taking donkey skin as a raw material through decoction and concentration, mainly contains 18 amino acids and collagen hydrolysate with small molecular weight, and is widely used for treating diseases such as anemia, deficiency of both qi and blood, palpitation and insomnia, inappetence and the like. Unfortunately, the wide use and the over-demand of the donkey-hide gelatin drug inevitably lead to the fact that the donkey-hide gelatin drug cannot be used in the effective period in time and is wasted in the healing period. In particular, bottled liquid drugs are more likely to break down and contaminate groundwater systems or stab sanitation workers than other packaging formats. Incineration or centralized landfill are two main treatment modes for treating overdue waste drugs at present, but the two main treatment modes are contrary to the concepts of circular economy and sustainable development, so that a more friendly and reasonable management scheme needs to be found, and secondary non-medical values in the overdue drugs are fully utilized.
Considering that the overdue donkey-hide gelatin waste medicine contains abundant carbon elements and a small amount of nitrogen elements and sulfur elements, the overdue donkey-hide gelatin waste medicine may be a satisfactory nitrogen/sulfur co-doped carbon source precursor, but no relevant research report exists at present.
