PLASTIC IS
EVERYWHERE
A material built from tiny repeating pieces — and shaped into almost anything.
01 · WHAT PLASTIC IS
PLASTIC BEGINS WITH LONG CHAINS OF MOLECULES
Small building blocks join into polymers: long, repeating molecular chains.

05 · THE TRADE-OFF
DURABILITY IS USEFUL — AND CREATES A WASTE CHALLENGE
The same molecular chains that make plastic last can also make it difficult to break down.
OECD projection: plastics lifecycle emissions are projected to rise from 1.8 Gt CO2e in 2019 to 4.3
Gt CO2e in 2060.
06 · A SYSTEMS PROBLEM
RECYCLING WORKS BEST WHEN DESIGN AND SYSTEMS WORK TOGETHER
USE LESS
Avoid unnecessary
single-use material.
