Resource recycling potential of magnetic resonance imaging in China
With the expansion of Chinese medical device industry,scrapped medical electronic devices increase year by year.However,its annual scrap volume is unclear,and research on its resource value is also limited.Therefore,taking magnetic resonance imaging(MRI)equipment as an example,the Logistic model,grey prediction model,Weibull distribution+market supply A model were used to predict its per million per capita ownership,sales and scrap volume.Meanwhile,the resource availability of the scrapped MRI equipment was assessed.The results showed that by 2032,MRI equipment sales would grow from 2 251 units to 5 160 units from 2023 to 2032,with a compound annual growth rate of 8.6％.By 2032,per million per capita ownership of MRI in China would be 32 units.In 2023-2033,the annual scrapped volume of MRI equipment in China would increase from 1 476 to 3 240 units,and the cumulative total scrapped volume could reach 287200 t.The cumulative recoverable amount of NdFeB magnetic would be 9 606 t,which was 125 700 t for niobium titanium.MRI recyclable aluminum,iron,circuit boards and wires,glass fiber reinforced epoxy resin,copper,low carbon steel,stainless steel were in a descending order,respectively 40 400,36 200,29 800,17 700,9 700,9 500 and 9 100 t.The results of this study can provide a guidance for the recycling policies on end-of-life medical electronic equipment and its industrial development.
