What is Sustainability?
Dictionary
If we look up sustainability/ sustain in the dictionary
Sustainable (adjective):
Able to be maintained at a certain rate or level
Sustain (verb)
To supply with nourishment
To keep up/ prolong
But what exactly is it?!

6. What is Sustainability?
Colored bars – Two columns 6
What is Sustainability?
The Brundtland Commission
The common definition – The Brundtland Commission 1987
World leaders across the globe
Raise awareness for the need for sustainable development
“Development that meets the needs of the present without compromising the ability of future generations to meet their own needs”

9. Measure of human demand on earths ecosystems
Ecological Footprint
Measure of human demand on earths ecosystems
Standardised measure for natural capital demand
Represents the amount of land taken up
Our needs
Our waste
Describes how many earths would be used
Widely accepted and researched
Calculate your own usage:

10. Ecological Footprint – My Demand

11. Ecological Footprint – My Demand Vs. Country Average

12. Ecological Footprint – My Demand on Biomes
Biome - a large naturally occurring community of flora and fauna occupying a major habitat, e.g. forest or tundra.

13. How Does This Affect the Earth?
Fossil fuel usage
Non renewable/ finite
C02 release
Cattle farming
10x more damaging than other agriculture
28x more land 11x more water than pork, poultry, eggs or dairy
Population increase
2014 7bn+
80m increase each year bn
More people = More housing + mouths = = Less green space and food = unsustainable

14. Why Are We Now Doing Things Different?
Industrial Revolution – 1760 – 1820/40
From hand to machines
Increased efficiency with power
Swansea – most polluted city in the world
Water pollution
Air pollution – killed, killed
1956 first major environmental legislation Clean Air Act
Since then a massive amount of legislation
Water Framework Directive
Habitats Directive
Industrial Emissions Directive
Landfill Directive
Environment Act
Awareness

18. Sustainability at Home – The Waste Hierarchy

19. Sustainability at Home
What are you doing differently?
Recycling
Food, paper, tins, glass, plastic
Energy Saving
Energy saving lights/ appliances
Turning off lights/ appliances
Washing at 40°
Grow your own
Wise consumer choices
Sustainable sourced foods
Rainforest alliance
Fair trade

22. Sustainability and Steel
Steel making historically unsustainable
Energy
Raw materials
Carbonaceous material – coal, coke
Iron ore
Limestone
Oil
Gas
Multiple locations
Multiple processes
Harbour – Sinter Plant/ Coke Ovens/ Blast Furnace – BOS Plant – Concast – Hot Mill – Cold Mill – Annealing
4.5m t steel
2.2t CO2!

23. Steel Making – The Conventional Blast Furnace
Where iron ore (FeO) is reduced to make iron (Fe)
Use of coal, coke, gas, iron ore and sinter, limestone
Series of chemical reactions
Hot iron 1500 °
Temperatures up to 2500 °
Used to use oil
Waste incineration directive (WID)
Produces wastes (historically)
Gas
Slag
Now recycled

24. Steel Making – HIsarna Blast Furnace
Part of ULCOS
New method of sustainable steel making
Cuts out coke and sinter
Less material use and CO2 production directly and indirectly
Use of preheated coal – twin screw reactor – improved thermal efficiency
Use of Iron ore fines – cyclone – hits walls – partial reduction
Converter reduces not melts iron oxide - reactor
Iron ore is tapped off as usual
CO and CO2 gasses off the top
