What is Sustainability? Colored bars – Two columns 4 What is Sustainability? Google Google sustainability: 1998 - <250k hits 2008 - 4.8million hits 2014 – 11 million hits!
What is Sustainability? Colored bars – Two columns 5 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?!
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”

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: www.myfootprint.org
Ecological Footprint – My Demand
Ecological Footprint – My Demand Vs. Country Average
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.
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 2050 11bn More people = More housing + mouths = = Less green space and food = unsustainable http://www.bbc.com/news/science-environment-28409704
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 – 1873 700 killed, 1952 4000 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

Sustainability at Home – The Waste Hierarchy
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
Sustainable Development – Housing and Buildings New development in housing market BREEAM (Building Research Establishment Environmental Assessment Methodology) Code for sustainable homes (CSH) run by BRE int.

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!
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 http://www.steel.org/Making%20Steel/How%20Its%20Made/Processes/How%20A%20Blast%20Furnace%20Works%20larry%20says%20to%20delete.aspx
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 http://www.ulcos.org/en/research/isarna.php#
