Material	type	Sustainable use
		reduce		reuse	recycle
bricks	Construction material	Using concrete blocks as an alternative		·         can be used for backfilling purposes. ·         Bricks extracted from abandoned building can be used for decorative and temporary structures.
timber	Construction material	·         Using alternative materials such as steel which are easily recyclable. ·         Re-growing the forestry as much as possible. ·         Applying preservatives to increase durability			Can be re-milled into flooring Can be chipped to make engineered board Can be used as boiler fuel.
Steel	Construction material	·         By applying coatings and galvanizing, durability can be increased which in turn reduces the amount of steel that would be used in future. ·         create sections that take advantage of distancing the material from the neutral axis in the production of structural steel shapes.		·         It must be possible to dismantle the joints. As a consequence the components can be removed from the structure without damage and can be reused. ·         When a building is demolished, all the steel - both reinforcing steel and structural steel - is removed can be brought together for reuse.	Metals are melted down and reformed into metal products.
Fossil fuels	Energy source	Choosing a renewable alternative energy source. For example, when the building is in operation, solar power can be used for heating purposes. Further, bio gas can be produced using the organic waste collected.
Water	Water	·         Efficient usage. ·         Waste water treatment reduces the virgin water extracted.	Reusing treated waste water for gardening purposes and flushing purposes (non- potable uses)
