Disposal of waste

At MIDES we treat more than 2,000 tons of daily waste, coming from city halls, hospitals, health units, medical centers, laboratories, clinics and private companies, among others.

When the waste is disposed of in the sanitary landfill, it is spread, compacted and covered with clay on a daily basis.

The liquids resulting from organic waste are called: Leachate. These are sent to oxidation ponds, by means of the collection system installed at the bottom of the cells, to later be recirculated, by means of sprinklers. In this way, the Sanitary Landfill becomes a biodigester due to the hydraulic seal, a product of leachate spraying on the clay. covering treated solid waste. This maximizes biogas production.

Inactivation treatment of expired or damaged drugs.

We have developed state-of-the-art technology to end an environmental pollution problem, caused by Expired and / or Damaged Medications; This technology consists of giving a physicochemical treatment to the waste to make it more stable and biodegradable substances in the environment.

After the drug is treated, it is chemically analyzed in our Quality Control Laboratory to determine if the process has been effective and then it will be handled as common waste.

Bio-infectious waste treatment

Since 2000, we have installed the Sterilization System by means of Humid Heat (Autoclave), giving a response to the environmental and social problems of bioinfectious waste produced by hospitals and clinics, through a rigorous treatment that complies with the standards and international quality standards.

The benefits of this type of treatment for bio-infectious waste and drugs are:

  • Complete sterilization of bioinfectious medical waste, preventing the spread of possible contagion of diseases.
  • It guarantees the strict control of bio-infectious waste.
  • Environmental Protection.

Currently, in a global context under the COVID19 pandemic, MIDES is an ally for the health sector, both public and private; being an important reference in the management of waste that comes from areas in contact with patients who were infected by the virus.

The final disposal of this type of waste is carried out with certified biosecurity measures and under the care of the collaborators who intervene in the process, with occupational health and safety measures, within the framework of the strictest international protocols for the handling of the waste. wastes contaminated with highly contagious viruses.

At MIDES we comply with the international regulations for microbiological inactivation in infected waste, according to the State and Territorial Association on Alternate Treatment Technologies (STAATT) - Level III, which defines the following as such:


Complete destruction of all forms of microbiological life.


Reduction greater than 99.9999%

As part of the tests we carry out in our laboratory, we place BIOTESTs in the containers with DBI that enter the AUTOCLAVE, which are biological indicators that indicate the sterilization effectiveness of the DBIs, guaranteeing the effectiveness of our process.

The benefits of this type of treatment for bio-infectious waste and drugs are:

  • Complete sterilization of bioinfectious waste
  • It does not generate negative environmental impacts.
  • Strict control of bioinfectious waste.
  • Strict security measures for working personnel.
  • Environmental Protection.
  • Protection for health.
