"Hospital Waste: waste resulting from health care activities for humans or animals, in the areas of prevention, diagnosis, treatment, rehabilitation or research and education, as well as from other activities involving invasive procedures, such as acupuncture, piercing and tattooing, and waste resulting from thanatopraxy." According to Decree-Law nº 102-D/2020.

Medical Wastes must be subject to selective separation at their place of origin so that they can undergo appropriate and differentiated treatment according to their classification that also includes the principles that should govern the organization and overall management of waste such as the effective risks, labour protection within the sector, the operability of the various sections, ethics and risk perception by the public.

According to the Ordinance 242/96, the Medical Wastes are classified as follows:

Group I has no special requirements in its treatment. In this Group are included:

  • Wastes from general services (such as offices, meeting rooms, lounges, toilets, changing rooms, etc...); Wastes from support services (such as workshops, gardens, warehouses and others);
  • Common packaging and wrappings (such as paper, cardboard, mixed sleeves and others of similar nature);
  • Wastes resulting from cooking and scraps of food served to patients not included in Group III.

Medical Wastes that are not subject to specific treatments and may be equivalent to urban belong to Group II:

  • Orthopedic supplies, such as splints, plaster casts and bandages not contaminated and with no traces of blood;
  • Diapers and removable covers not contaminated and no with traces of blood;
  • Personal protective equipment used in general service and support, except the ones used in waste collection;
  • Empty containers of drugs or other products from clinical use, except those included in Group III and Group IV; Uncontaminated saline bottles, except those from group IV.

Group III consists of contaminated wastes (or suspected to be so) which are susceptible of incineration or other effective pretreatment, allowing subsequent disposal as urban wastes, and they are:

  • All wastes from rooms or wards of suspected infectious patients, hemodialysis units, operating theater, treatment rooms, autopsy and pathological anatomy rooms, clinical pathology and research laboratories, with the exception of group IV wastes;
  • All materials used in dialysis; - Unidentifiable anatomical parts; - Wastes resulting from the administration of blood and blood products;
  • Systems used in the administration of serums and medicines, with the exception of group IV; - Fluids bags collectors and their respective systems;
  • Contaminated (or with traces of blood) orthopedic supplies (splints, plaster casts and bandages), prosthetic material removed from patients;
  • Contaminated (or with traces of blood) diapers and removable covers;
  • Personal protective equipment used in health care and support services in general which was in contact with contaminated products (such as gloves, masks, aprons and other).

Group IV is composed by various types of wastes that have incineration requirements:

  • Identifiable anatomical parts, fetuses and placentas; - Animal corpses of laboratory experience;
  • Cutting and piercing materials: needles, catheters and all invasive materials;
  • Rejected chemicals and pharmaceuticals products when not subject to specific legislation;
  • Cytostatic and all materials used in handling and administrating them.


BioVia guarantees the delivery of suitable containers for the packaging of group III and group IV medical wastes so it can be done in order to clearly identify its origin and its type (since the wastes belonging to Group I and Group II are equivalent to urban wastes, they are not considered hazardous medical wastes), so that screening can be performed as efficiently as possible at the production site.
