DASRI is waste that has been in contact with blood, biological fluids or infectious agents, plus sharp equipment. It requires a specialised route (incineration or autoclaving). DAOM is ordinary waste - packaging, paper, food leftovers - following the normal route. Confusion between the two is the leading cause of additional costs: unsoiled syringe packaging is DAOM, not DASRI.
