Healthcare Waste Management: Challenges and Solutions

In course

ENV-470: Development engineering

This course teaches the fundamentals of technologies for development (Development Engineering) to design, pilot, and deploy appropriate, affordable and robust technologies to address sustainable development challenges and especially those related to extrem ...

Description

This lecture covers the challenges posed by healthcare waste, such as infection risks and environmental pollution, and explores solutions like incinerators. It also delves into the specific case of Mozambique, highlighting the impact of the lack of proper waste management on public health. Additionally, it presents a project focusing on developing an electricity-free cold box for vaccine and food storage in low-income settings, addressing the critical issue of maintaining a continuous cold chain for essential products.

Klaus Benedikt Schönenberger

Vision: Scientific research and technology development can be mobilized to help the poorest and most vulnerable in this world. Klaus Schönenberger obtained an MSc in Microengineering (1993), followed by a PhD (1996) from the Swiss Federal Institute of Technology in Lausanne (EPFL). After a post-doc at Lawrence Livermore National Laboratory in California, he spent over 10 years in the medical devices industry in leading positions such as Vice-President of Worldwide R&D in a

100m company and Global Vice-Resident of Research and Technology in a

1bn company. In 2009, as he was working for a medical devices company, he received a shock: he realized that there is a huge imbalance in access to medical technology in industrialized versus low and middle-income countries. After a closer look, he discovered that he imbalance’s main cause is a mismatch between existing technologies and business models, with those needed in low and middle-income countries. He decided to leave industry and, in 2009, he co-founded the EssentialMed Foundation, an innovative non-profit venture. In 2011, realizing that both technology and business models needed a profound rethinking, he joined EPFL where he launched EssentialTech, an initiative inspired by the philosophy of EssentialMed but expanded to a much wider portfolio of "essential" technologies. The university-wide program aims to develop innovative technologies and business models, for the benefit of sustainable development in low and middle-income countries. In this role, he has already launched and overseen a dozen large projects. Major Humanitarian actors such as the ICRC, MSF and Terre des Hommes took notice of the innovative approach proposed, and decided to collaborate in 2015-2016. This has resulted notably in the joint creation between EPFL and ICRC, of the Humanitarian Tech Hub at EPFL. In May 2017, Klaus directed and launched a MOOC(Massive Open Online Course) entitled “Technology Innovation for Sustainable Development” which aims to spread the unique methodology and approach worldwide. As of today, more than 6000 people have enrolled. In 2018 a first spin-off company was created. Award winning Pristem SA will deploy an innovative new digital xray imaging system, specifically designed for low-income contexts. In December 2018, the creation of the EssentialTech centre was announced by EPFL's presidency, and Klaus is now the Centre's director. Another spin-off of the EssentialTech Centre is the company HMCare, launched in 2020, which is deploying a transparent surgical mask.

Biomedical waste

Biomedical waste or hospital waste is any kind of waste containing infectious (or potentially infectious) materials generated during the treatment of humans or animals as well as during research involving biologics. It may also include waste associated with the generation of biomedical waste that visually appears to be of medical or laboratory origin (e.g. packaging, unused bandages, infusion kits etc.), as well research laboratory waste containing biomolecules or organisms that are mainly restricted from environmental release.

Public health

Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals". Analyzing the determinants of health of a population and the threats it faces is the basis for public health. The public can be as small as a handful of people or as large as a village or an entire city; in the case of a pandemic it may encompass several continents.

Hazardous waste

Hazardous waste is waste that has substantial or potential threats to public health or the environment. Hazardous waste is a type of dangerous goods. They usually have one or more of the following hazardous traits: ignitability, reactivity, corrosivity, toxicity. Listed hazardous wastes are materials specifically listed by regulatory authorities as hazardous wastes which are from non-specific sources, specific sources, or discarded chemical products. Hazardous wastes may be found in different physical states such as gaseous, liquids, or solids.

Incineration

Incineration is a waste treatment process that involves the combustion of substances contained in waste materials. Industrial plants for waste incineration are commonly referred to as waste-to-energy facilities. Incineration and other high-temperature waste treatment systems are described as "thermal treatment". Incineration of waste materials converts the waste into ash, flue gas and heat. The ash is mostly formed by the inorganic constituents of the waste and may take the form of solid lumps or particulates carried by the flue gas.

Waste

Waste (or wastes) are unwanted or unusable materials. Waste is any substance discarded after primary use, or is worthless, defective and of no use. A by-product, by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero. Examples include municipal solid waste (household trash/refuse), hazardous waste, wastewater (such as sewage, which contains bodily wastes (feces and urine) and surface runoff), radioactive waste, and others.
