COMTEM is in charge of the international sales and distribution of the world leading technology for medical waste sterilization equipment. COMTEM STERIFLASH and STERI2FLASH systems have past the most demanding standards in terms of waste sterilization. In the STERIFLASH and STERI2FLASHM systems, medical waste is shredded through a patented shredding cassette, capable of grinding up to 3.6 mm of diameter (10 mm2-section) metal parts. The shredding cassette has specifically been designed for different types of medical waste. The shredded waste is decontaminated by a hot steam process at high pressure. At the end of the process, the decontaminated solid waste can be collected and processed like ordinary, infectious-free municipal waste. Decontaminated liquids are drained off via the waste water network. Ask for STERIFLASH and STERI2FLASH certifications and homologations for further references.

COMTEM is born inside a group of technological companies that started in 1931, with a technological approach when addressing customer needs.

With more than 40 years’ experience in manufacturing equipment, the Engineering Department focuses on the continuous improvement of current models as well as developing new solutions to meet upcoming demands.

OUR MISSION is to provide, through technology, EFFICIENT SOLUTIONS to address the current ENVIRONMENTAL CHALLENGES of the world.

The STERIFLASH equipment, line of machines for hazardous health care waste on-site treatment, represents a breakthrough solution for the waste treatment market worldwide: its qualitative advantages (environmental, public and users safety, as well as risk reduction for public healthcare, among the most relevant ones), would represent by themselves a solid market argument for success, but on top of those, the quantitative advantages of the system (economic, due to a significant cost reduction of the overall process) enhances the strengths of the solution as a successful market proposal, for both emerging economies as well as developed countries.

In developed countries, out of every 100 kg of waste generated in a sanitary centre, from 75 to 85 kg are of innocuous waste, and the remaining 15 to 25 kg are of the so called Hazardous Health Care Waste (HHCW). Still nowadays, main worldwide practice for treating that 25 kg of HHCW is incineration.

Of these, only one fourth is burnt in adequate incinerators. Leaving aside the energy consumed in the process, USA and EU studies, determined that incorrect incineration of this type of waste, is the main cause of dioxins and furans emissions to the atmosphere.

The World Health Organization (WHO) recommends HHCW to be processed preferably on-site (WHO handbook Safe management of waste from health-care activities commonly known as 'the Blue Book” (2014) See: page 41 (The “proximity” principle), 45-46 (WHO guidance) and 55 (Option 1 of Step 5)”), which would be at the nearest place and time to where they are generated, and by methods alternative to incineration. In accordance with the “Principle of Proximity” and main objective of Basel Convention on the Control of Trans-Boundary Movements of Hazardous Wastes and Their Disposal 8. UNEP, 1992: “The main objectives of the Basel Convention are to minimize the generation of hazardous wastes, treat those wastes as close as possible to where they were generated and reduce trans-boundary movements of hazardous wastes”. Signed by most EU members, the Stockholm Convention global treaty, the International Convention on the Elimination of POPs, valid from 2004, made emphasis in the directive of promoting technologies alternative to incineration for the treatment of HHCW.

The STERIFLASH™ solution by COMTEM™ focuses on the “on-site” treatment of this waste fraction versus “off-site” treatment, thus assumes the principle of 'proximity' established by the different standards of waste treatment and recommended by the most important institutions for the sector, since it brings the treatment of waste to the place where it is generated. STERIFLASH™ machinery uses a thermal process (steam) which replaces the inadequate incineration normally used as a solution to remove HHCW. The STERIFLASH™ technology , changes the steam thermal process working scheme that is currently being used to treat this waste. STERIFLASH™ technology, first grinds the RSP reducing its volume, treats the waste through controlled Temperature and Pressure cycle with saturated steam, hence gaining efficiency. Thus the HHCW are processed at the nearest possible site where are generated.

With the on-site treatment solution by shredding and saturated steam cycle, the qualitative advantages in:

  • Environmental aspects: emission reduction solution, based on steam; traffic reduction with carbon footprint reduction, waste volume reduction, facilitation of recycling processes, landfill impact reduction.
  • Public Safety aspe: reduction of workers and public safety risks related to HHCW.
  • Public Health aspects: more efficient waste treatment processed with lower risks of infection, deactivating the risk of contagious by shortening the life and transport time and distance of infected waste.

As well as quantitative advantages:

Economic: by reducing not only the cost of the overall process but also eliminating stages which become unnecessary.
