Plastic seals food, sterile medical implements, medicine, beverages, etc… it’s seems like plastic is used as a way to seal things safely. Post pandemic rising, I see even more. My work used to be have plastic utensils in the cafeteria, for example, an already wasteful thing. Now, post-2020, every fork, knife, and spoon is individually wrapped in a plastic wrapper. I feel like the more my desire to escape plastic intensifies, the more plastic I see all around me everywhere.

How can we get away from plastic as a safety layer?

    An important source of plastics is road traffic emissions. Kole et al. reported global average emissions of tyre wear particles (TWPs) of 0.81 kg year−1 per capita, about 6.1 million tonnes (~1.8% of total plastic production). Emissions of brake wear particles (BWPs) add another 0.5 million tonnes. TWPs and BWPs are produced via mechanical abrasion and corrosion.

    Most car braking systems consist of a disc or drum with either a pair of shoes or pads mounted in callipers. Brake linings consist of binders, fibres, fillers, frictional additives or lubricants and abrasives. Thus, BWPs are a complicated mixture of metal and plastic. BWP emissions depend on the bulk friction material on the frequency and severity of braking speed, weight, condition and maintenance of the automobile and the environmental conditions.
