The Science of Climate Change

Climate change is no longer a distant threat or just a possibility, it is now a reality for all of us. In this pathway, Kevin Trenberth, a renowned climatologist, delves into the science behind climate change. He first introduces the climate system, its main components and forces.

Tackling the Plastic Crisis

Plastic pollution is by far the biggest threat to our oceans and this remains an incredibly tough problem to solve. Plastic credits could potentially serve as one of the much needed solutions for this crisis.

The Scale of the Net Zero Challenge

The price of meeting net zero is estimated to be between $100-150 trillion over the next 30 years. Regardless of this cost, we need to reach net zero before climate change does irreversible damage to the environment and the economy.

ESG, Sustainability and Impact Jargon Buster

ESG, sustainability, impact… they all just mean green, right? Not quite. Despite being used often interchangeably, there are distinct differences between these terms.

How Does Plastic Recycling Work?

9 mins 33 secs

Overview

Plastic resin codes are a set of numbers that instantly identify what sort of plastic a product is made of. The lower the resin code, the more probable the plastic type will be easily recyclable. The two main methods of plastic recycling are mechanical recycling (recovering plastic waste by mechanical processes such as sorting, washing, drying, grinding, re-granulating and compounding) and advanced recycling (which uses thermochemical reactions to break plastics down into completely new products such as new monomers, new polymers, fuel, energy and other commodities). Fundamentally however, we should be following a waste hierarchy, with prevention of new plastics at the top and disposal as a very last resort.

Key learning objectives:

  • Identify the different plastic resin codes

  • Understand the benefits of recycling

  • Outline the two main types of plastic recycling

  • Assess the waste hierarchy
