> Plastics are mostly carbon and hydrogen atoms In general, this particular stuff is significantly different. The article mentions sodium hexametaphosphate [0] and guanidinium sulfate [1], which have phosphorous and nitrogen respectively. Those are both common in fertilizers and are implicated in algal blooms.
