ED1231 Lecture Notes - Lecture 9: Frozen Food, Waste Minimisation, Polypropylene
Environmental Science, Technology and Enterprise
Lecture 9 – Week 9 – Waste
Assignment
- Due Friday 27th by 5pm
- 4 Parts
- Create a sequence of lessons with background information
o Demonstrate comprehensive understanding of curriculum planning
▪ Codes
▪ Lesson Length!!
▪ Think about objectives – In assessment section
▪ Hattie – Monitor student learning and provide feedback
- Part b and c – Link with sequence of lessons
o Critical and creative thinking table!
- USE AUSTRALIAN CURRICULUM, not WA
- Good assignments will LINK TO OUTSIDE THINGS – ocean week, competitions etc
Why Critical and Creative Thinking? – IN THE EXAM
- “Responding to the challenges of the twenty-first century – with its complex environmental,
social and economic
- Pressures – requires young people to be creative, innovative, enterprising and adaptable, with
the motivation, confidence and skills to use critical and creative thinking purposefully”.
How is it organised?
- 4 key ideas – Make up an acronym – REMEMBER THESE FOR EXAMS
- Levels or bands (not organised in year levels)
- Learning continua for each of the key ideas
- How can this be represented in your assignment?
Part C: Critical and Creative Thinking (250-350 words)
- In the Australian Curriculum: Technologies, students develop capability in critical and creative
thinking as they imagine, generate, develop and critically evaluate ideas. Using examples
from your program describe how you will incorporate the key ideas for critical & creative
thinking into your teaching. This may be presented as a grid, a mind map or as a written
summary.

Solid Waste
- “Waste is classified into either organic (living) or inorganic (non-living). Organic waste can
include food scraps, paper, grass clippings and other plant material. Inorganic waste includes

items such as plastics, glass, aluminum and other metals along with sand and bricks and
hazardous waste.”
- Industrial solid waste – produced by mines, farms, industry (ISW)
- Municipal solid waste – produced by households and workplaces (MSW)
Waste
- In Australia
- Pre 1788
- Early colonial period
Our world
- We live in a materialistic world!!
- We shop more than we have ever shopped, spurred on by increased choice.
- We buy disposable goods and convenience foods produced cheaply by modern
manufacturing.
- This may please us as consumers, but this habit creates enormous amounts of waste in the form
of used goods and discarded packaging.
- This waste is taking over our world!!
Wastes
- Environmental consequences
- Economic consequences
- Social consequences
Waste in WA
How do we manage waste?
- Landfill
o Historically - most convenient form of waste disposal.
o There are environmental problems associated with conventional landfills such as:
• Land clearing – loss of biodiversity and habitatso Wind-blown waste – litter
entering waterways and harming and
• killing birds and aquatic animalso Leachate – in unlined landfills, toxins have the
potential to pollute
• soil and groundwatero Social impacts – visual, smell, noise from trucks travelling
to and
• from site and vermino Greenhouse gases – organic material can break down
• anaerobically (with no oxygen) resulting in the production of methane (ch4) and
carbon dioxide (co2).
- Incineration
o Volume of solid waste reduced by 90%
o Produces heat which can be used to generate electricity
o Less co2 than fossil fuel plants
o Air pollution (toxic) – co, particulates, heavy metals
o Production of ash
Alternative Waste Treatment Technologies
- AWT technologies convert waste into energy or useful by- products.
o The overall aim is to increase the recovery of resources from the waste stream and
minimise the impact on the environment.
▪ Modifying conventional landfillo Thermal treatmento Biological treatment –
worms, bacteria
- DEPENDS ON TYPE OF MSW AND LOCATION!
