Also commonly referred to as Hide Glue, Protein Glue, gelatin-based adhesive and cake glue. Gelatin used in animal glue is a recycled by-product of hides and bones of cattle and pigs.

Even books about veganism or animal rights are likely bound with animal-based glue, printed on equipment lubricated with animal fats, and packaged by workers who eat meat and wear leather shoes.
