How is waste glass recycled?
Show answer
It is separated by colour and type, then crushed and melted so it can be reshaped into new products.
Name a product other than bottles and jars made from recycled glass.
Show answer
Insulating glass wool, used for wall insulation in houses.
Besides the raw material used, what other factor determines how sustainable a manufacturing process is?
Show answer
The amount of energy used in manufacturing — high energy use from burning fossil fuels makes a process unsustainable even with a renewable material.
How are metals recycled?
Show answer
They are melted down and then reformed into different products.
Why is wood often a more sustainable material than plastic?
Show answer
Wood is renewable because more trees can be grown, whereas plastic comes from crude oil, a finite resource.
Why is scrap steel added to pure iron when making steel?
Show answer
It reduces the amount of pure iron that must be extracted from the ground, saving resources and energy.
Why are scrap metals usually separated into different elements before melting?
Show answer
So that each metal can be reformed into a pure product — e.g. copper wires are separated from iron bars.
What does it mean to reuse a product?
Show answer
To use the item again, either for the same purpose or a different one, without reprocessing it — e.g. refilling a glass bottle with water.
How do catalysts help make industrial processes more sustainable?
Show answer
They reduce the energy required for the reaction, so less energy (often from fossil fuels) is used.
Steel is an ? of iron containing small amounts of other elements.
Show answer
alloy
Define sustainable development.
Show answer
Development that meets the needs of current generations without damaging the ability of future generations to meet their own needs.
