Medical Incinerators

Addfield Medical incinerators are utilised worldwide on six different continents by private hospitals, government primary health care services, medical waste management companies and by the vast majority of the world’s largest aid agencies globally.Our general range is split into two defined sectors. The MP range is ideally suited to be installed directly in hospitals, laboratories and care practices. Ranging from a chamber size of 100kg to 500kg the MP range is ideal for disposing of hospital waste.The large format GM range is ideally suited to the bulk disposal waste management companies and emergency use. Also with a range of machines, the GM Range is ideal for bulk waste generated from Aid Agencies and large hospitals.All of the Addfield medical incinerators have the option for continuous loading, filtration systems and continuous monitoring. For larger scale incineration disposal please visit our high capacity range. Speak to the experts today.Addfield….Simply Built Better

  • What Medical Incinerator do I need?

    First and foremost are facility needs to size a machine according to the amount of waste it is processing.

    As a waste management company, or pharmacy this maybe expressed in ‘kg’ ‘m3’ or number of 1100/770/240 litre bins collected in one day.

    As a hospital this value again maybe expressed in physical terms or in the number of bed a specific hospital may have. Which this information we can estimate how much waste will be generated per occupied bed. This value is typically between 0.3kg-0.8kg, but can vary depending on geographic location and waste segregation practices in place, so

    please contact us for more information.

    Ideally in your estimation you should allow for some extra capacity should you waste loads increase in future.

    Secondly the type of medical waste you are looking to dispose of will play a major factor if how much a specific machine will process. See ‘How does the Calorific Value of the waste determine the incineration process’ below

  • Why buy an Addfield machine ?

    Addfield have been building cremation machines for over 35 years as a market leader we are dedicated to building the best quality machines available from laying the refractory bricks and creating a 180mm internal thick refractory wall that ensure the heat stays where it is needed in the chamber to ensuring that our machines are fit to work in all environments indoors and out.

    All our machines are built with ease of use in mind and on average Addfield machines are 40% more efficient.

  • The Secondary After Chamber.

    The primary filtration method on all Addfield incinerators and cremators is the secondary after chamber. The resulting incineration flue gas is oxidised in the secondary after chamber. To ensure complete and thorough oxidisation the flue gas must remain in the after chamber for a minimum of two seconds the W.H.O. states “If hazardous wastes with a content of more than 1% halogenated organic substances, expressed as chlorine, are incinerated, the temperature has to be raised to at least 1100°C” in the secondary after chamber.

    Guidelines for Safe Disposal of Unwanted Pharmaceuticals in and after Emergencies, WHO/EDM/PAR/99, World Health Organisation.  WHO

    Further stages of the filtration are also available, and can be found here: These systems won’t be right for every waste stream, the below gives a generalised overview of systems however please consult Addfield for further advice, as every waste stream will be different.

    Temperature Collapse Kits:

    To prevent dioxin and furan reformation

    De-Nox Kits: [De Nox Kit Link]

    Typically only required on high capacity diesel plants  to remove or reduce NOx emissions.

    Cyclone Scrubber: [Cyclone Link]

    A cost effective scrubber system, with typically up to 50-60% removal ratio on some parameters

    Wet Scrubber System: [Wet Scrubber Link]

    A highly effective removal system, that achieves a high particular removal ratio whilst preventing dioxin reformation.

    Ceramic Filtration Systems: [Ceramic Filtration Link]

    One of the most effective removal system on the market, with up to a 97% removal ratio of certain parameters, however requires a larger area for implementation.

    Acid Scrubbers: [Acid Scrubber Link]

    A bolt on system that to remove acid gasses such as SO2, HCL with the use of hydrated lime.


  • What are the filtration methods?

    There are various stages of the filtration on incineration systems, some are compulsory other maybe recommended depending on the waste stream and throughput.

  • What about medical incinerator emissions?

    Medical waste incinerators have to hit specific emission limits, these limits will vary depending on the location of which a machine is installed. For example emission limits in the UK, far exceed those of Asia. As such when a machine is purchase from Addfield, you should feel confident in the knowledge that you are buying an incinerator of the highest of standards from a European Manufacture.

    Our machines have been emission tested to the highest of standards:

  • What should I look for in a medical incinerator?

    As soon as any medical incinerator is used with medical waste it is considered a bio hazard because of the nature of the material it deals with. As such it is extremely important to choose a machine that is robust and reliable long term. A thick steel casing will ensure long term sustainability as will an efficient design. A modular refractory design such as monolithics or refractory firebricks will ensure long term maintenance of the machine whilst further extending its life cycle. Efficient design and thick refractory linings of above 150mm will ensure minimum heat stress and reduced fuel consumption.
