7.3 Solid waste

Guiding question

How can societies sustainably manage waste?

SL and HL knowledge statements

7.3.1 Use of natural resources generates waste that can be classified by source or type.

7.3.2 Solid domestic waste (SDW) typically has diverse content.

7.3.3 The volume and composition of waste varies over time and between societies due to socioeconomic, political, environmental and technological factors.

7.3.4 The production, treatment and management of waste has environmental and social impacts, which may be experienced in a different location from where the waste was generated.

7.3.5 Ecosystems can absorb some waste, but pollution occurs when harmful substances are added to an environment at a rate faster than they are transformed into harmless substances.

7.3.6 Preventative strategies for waste management are more sustainable than restorative strategies.

Jack Johnson has a few things to sing about the three R’s.

7.3.7 Different waste disposal options have different advantages and disadvantages in terms of their impact on societies and ecosystems.

7.3.8 Sustainable options for management of SDW can be promoted in societies.

7.3.9 The principles of a circular economy provide a holistic perspective on sustainable waste management.

Possible engagement opportunities

Turn these into CAS activities connected to the UN SDGs.
Visit the local recycling centre and learn about how waste is handled locally.
Find out what happens to waste in your society—how much is recycled, reused, remade, goes to landfill or incineration, or is shipped to another country.
Assess the waste management in the school, and promote ways of reducing or reusing waste.
Raise awareness of circular economy options in the community.
Become involved in a Repair Café or set up a Library of Things.

Happy learning!
