Quick explanation

Discuss disposal and biodegradability of polymers

  • This point belongs to Polymers (A-level only), especially Polymerisation and polymer properties (A-level only).
  • You need to be able to discuss disposal and biodegradability of polymers.
  • The key ideas to know are polymer.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Why it matters

This objective helps connect Polymerisation and polymer properties (A-level only) to exam-style questions, flashcards, and revision notes for Polymers (A-level only).

Quick student answer

Which of the following polymers is biodegradable?

Direct answer

Polylactic acid (PLA) is a biodegradable polymer commonly used in packaging.

Key terms

  • Biodegradable polymers: Polymers that can be broken down by microorganisms into natural substances, reducing environmental impact.
  • Non-biodegradable polymers: Polymers that do not decompose naturally and can persist in the environment for long periods.

Common trap

Confusing biodegradable and non-biodegradable polymers: Focus on the chemical properties and sources of the polymers to determine their biodegradability.
