Source, Extraction, Recycling Flashcards
Paper + Boards
Trees. Chopped. Bark removed. Chipped into fibres. Mixed with water and glue and turned into Pulp. Pulp rolled and dried into stock form.
Expanded polystyrene, polypropylene
Crude oil
Timber
Trees. Chopped. Branches stripped. Bark removed. Logs cut into plank. Dried/seasoned in kiln.
Metal
Ore. Big rocks dug out of ground and Orr is mined/quarried from it or caves, contaminants are removed. Ore is then refined and made pure, collected and then melted and casted into pure ingots or other stock forms
Polymer
Crude oil. Polymerisation (attaching monsters together). Fractional distillation is used to separate the crude oil into different polymers
Recyclability of paper and boards
All apart from ones made from crude oil. Biodegradable. Foil lined board cannot be recycled as it is composite.
Recyclability of timber
Shredded and recycled into paper
Recyclability of metals
Metal collected and squashed. Metals shredded and placed in large furnace to melt. Purification happens. Molten metal carried by conveyer belt to cooling chamber
Recyclability of polymers
Finite. Synthetic ones aren’t biodegradable. Vegetable made ones are.
