Sustainability and shared smart and mutual – green growth (SSaM-GG) in Korean medical waste management

Since medical insurance was introduced in the Republic of Korea, there have been several increases concerning medical waste. In order to solve these problems, we have applied life cycle assessment and life cycle cost. But these methods cannot be a perfect decision-making tool because they can only evaluate environmental and economic burdens. Thus, as one of many practical methods the shared smart and mutual - green growth considers economic growth, environmental protection, social justice, science technology and art, and mutual voluntarism when applied to medical waste management in the Republic of Korea. Four systems were considered: incineration, incineration with heat recovery, steam sterilisation, and microwave disinfection. This research study aimed to assess pollutant emissions from treatment, transport, and disposal. Global warming potential, photochemical oxidant creation potential, acidifications potential, and human toxicity are considered to be environmental impacts. Total investment cost, transport cost, operation, and maintenance cost for the medical waste are considered in the economy evaluations though life cycle cost. The social development, science technology and art, and mutual voluntarism are analysed through the Delphi-method conducted by expert groups related to medical waste. The result is that incineration with heat recovery is the best solution. However, when heat recovery is impossible, incineration without heat recovery becomes the next best choice. That is why 95% of medical waste is currently treated by both incineration and incineration with heat recovery within the Republic of Korea.
