The differences in the two management frameworks will be observed initially in the equipment plan and subsequently in the type and financial allocation of the cleaning and waste management contracts in the operating phase of the center. In some cases, we can opt for technological solutions that increase the level of automation of intracenter management.

The treatment plant at El Inga currently has the operating capacity and trained personnel to process 1,000 kg/hour of infectious hospital waste; the plant operates in two continuous shifts of eight hours each.

Waste treatment is based on eliminating risk by sterilizing infectious hospital waste through the application of high temperature and pressure for a certain period of time. For this purpose, there are currently three autoclaves, which use steam to reach high temperatures that eliminate the life forms of bacteria, germs, viruses, and other infectious agents.
