01. Prelude: The Global Challenge of Medical Waste

In an increasingly interconnected world, we confront a myriad of pressing issues.  Medical waste management is one such issue that is frequently disregarded. As populations grow, so does the amount of waste generated by healthcare operations. This problem is exacerbated in developing nations such as South Africa, where expanding healthcare facilities generate huge volumes of medical waste. However, infrastructure and waste management systems are behind, posing a serious threat to human health and the environment.

02. A Brief History of Incineration: From Necessity to Dilemma

a. The Dawn of Waste Disposal: Fire as a Primal Tool

Incineration as a waste disposal process dates to the birth of civilisation when fire was our primary waste management tool. Its use in medical waste management was a logical step, prompted by the pressing need to dispose of infectious material in an effective and timely manner. However, as we gained a better understanding of the environment and the impacts of pollutants, we became more aware of the environmental and health repercussions of incineration.

b. The Industrial Revolution: Birth of Structured Waste Management

The late-nineteenth-century industrial revolution created a slew of waste products that demanded more structured waste management systems. During this period, the first incineration plants, or ‘destructors,’ as they were then known, were built in England. The use of incineration for medical waste disposal became more prevalent in the twentieth century. During the 1950s, the growth of infectious illnesses such as polio, as well as the introduction of disposable medical goods such as syringes and gloves, led to a significant increase in hazardous medical waste. The need to stop the spread of these infectious materials prompted the widespread use of incineration.

Incineration was viewed as an effective method capable of lowering the waste volume, rendering it harmless, and permitting convenient disposal. This technology was intriguing because of its capacity to manage a wide range of waste types, including those that are resistant to breakdown, such as plastics and non-organic materials. By the late twentieth century, however, the narrative had begun to alter. 

c. The Downside Revealed: Environmental and Health Implications

The disadvantages of incineration came to light as people became more conscious of environmental concerns and the impact of pollution. According to studies, incineration procedures generate toxic pollutants such as dioxins, furans, and heavy metals, most of which are unable to achieve complete waste combustion and result in high levels of contaminated ash which have serious consequences for both the environment and human health. The recognition of these consequences, together with the implementation of rigorous environmental legislation in many areas of the world, fueled the need for alternatives. The journey of incineration, from its inception as a rudimentary waste disposal method to its sophisticated but problematic use in medical waste management, reflects our evolving understanding of waste disposal, public health, and environmental conservation. Today, as we grapple with these complexities, we find ourselves at a crossroads, seeking innovative solutions that balance effective waste management with environmental sustainability.

03. Incineration Today: An Imperfect Solution

a. The Ubiquity of Incineration in Medical Waste Management

Despite its limitations, incineration has long been a staple of medical waste management. Its popularity stems from its capacity to efficiently manage a wide range of waste kinds, from sharps to infectious trash. Because of its widespread acceptance and implementation, it has become an essential component of waste management plans in hospitals and other healthcare institutions across the world.

b. The Environmental Impact of Incineration

However, the environmental impact of incineration is becoming a growing problem. Incineration processes emit a large amount of toxic emissions, such as greenhouse gases and other pollutants. These emissions contribute to air pollution and, more broadly, to climate change’s rising catastrophe. In addition to these environmental consequences, the waste from incineration causes health problems. Toxic gases and particles generated by incineration operations can cause respiratory diseases and other health concerns in populations nearby.

c. The Economic Considerations of Incineration

The economic impact of incineration is another impediment to its ongoing usage. The creation and ongoing operation of incinerators necessitate significant expenditure. They require considerable energy inputs and constant maintenance, making them costly to operate. These financial factors, in addition to the environmental and health ramifications, are causing stakeholders to reassess incineration as a long-term option for medical waste disposal.

The Incineration Challenge: The Sobering Reality

Environmental Havoc

Incinerators generate fly ash, bottom ash, and fugitive gasses such as acid gasses and carbon monoxide during incineration. Fly ash is made up of wastes generated by electrostatic precipitators and bag filters. It is estimated that fly ash accounts for 3-10% of incineration trash. The quantities of heavy metals in fly ash are greater than in bottom ash (Zikhathile et al., 2022).

Health Hazards:

Studies suggest that communities near incinerators have a higher risk of developing health issues such as cancer, heart disease, and respiratory problems due to exposure to toxic emissions and illegal dumping.

Budget Burner

Managing medical waste is an expensive endeavour, akin to a financial balancing act. According to a study on medical waste management in Turkey (Arikan, Ozturk, Demir, & Macin, 2013), building a medical waste incineration facility can cost anywhere from $120,000 to $6,000,000. The operational costs can range from $0.15 to $0.30 per kilogram. These figures underscore the financial burden of traditional medical waste management methods.

04. The Dawn of Innovation: Introducing Frictional Heat Sterilisation Technology

a. A Game-Changing Development

Amidst mounting concerns surrounding incineration, the quest for sustainable, cost-effective, and environmentally friendly solutions in the field of medical waste management has led us to a promising alternative: On-site Frictional Heat Sterilisation Technology.

Born from the ingenuity of the esteemed Italian company Newster, this groundbreaking approach has begun to redefine the very essence of how we treat and dispose of medical waste. No longer do we need to rely on the transportation and burning of waste, with all its inherent challenges. Instead, we can harness the transformative power of on-site frictional heat, a method as ingenious as it is effective. By bringing the sterilisation process to the very site where waste is generated, we enable hospitals and healthcare facilities to take full control of their waste management, ensuring not only safety and efficiency but also the preservation of our environment. With on-site capabilities at the forefront, we pave the way for a sustainable and responsible future in medical waste treatment.

b. A Versatile Answer to a Complex Problem

One of the remarkable features of Newster’s Frictional Heat Sterilisation Technology is its versatility. In a field as varied as medical waste management, the capacity to handle diverse waste types is crucial. Newster systems rise to this challenge, proving their mettle against a broad spectrum of waste, from sharps like needles and blades to cloth waste.
