—How chemists limit the problems caused by polymer disposal by: i developing biodegradable polymers ii removing toxic waste

Understand how chemists limit the problems caused by polymer disposal by: i developing biodegradable polymers ii removing toxic waste gases produced by the incineration of polymers.

Use —how chemists limit the problems caused by polymer disposal by: i developing biodegradable polymers ii removing toxic waste to connect the rule to the data and decision in the question.

This matters because —how chemists limit the problems caused by polymer disposal by: i developing biodegradable polymers ii removing toxic waste determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —how chemists limit the problems caused by polymer disposal by: i developing biodegradable polymers ii removing toxic waste to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —How chemists limit the problems caused by polymer disposal by: i developing biodegradable polymers ii removing toxic waste is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
