my doubt is that if the plastic used for recycling may be any medical things such as blood bags,cyringe(used for injuction,etc) the viruses from that material goes alive in the new material made frm recycled plastic?
Also, it is highly unlikely that things such as syringes and bags containing blood and other human liquids ARE recycled. Those things are considered Hazardous Waste and are placed in specifically designed sealed waste bins, and disposed of safely. It would be incredibly irresponsible for a hospital to recycle such products, as you've suggested, and it would also leave them open to millions of lawsuits!
Can you imagine?
I am sure that the plastic bags you see have been recycled from other plastics such as.. bags, pop bottles, laundry detergent bottles and the like..
hot burning plastic will burn skin and clothes.
