Life cycle assessments can evaluate the environmental impact of a product. Many products are recycled to lessen environmental impact. Modern metal extraction can reduce the impact on the environment.
What is the first stage in a life-cycle assessment?
Using the product during its lifetime
Extracting and processing the raw materials
Disposing of the product at the end of its lifetime
Which of the following is not part of a life-cycle assessment (LCA)?
Manufacturing the product and packaging
Advertising and marketing the product
Which of the following is a consideration when evaluating the manufacturing of a product?
Energy used by the manufacturing process
Wages paid to the workers on the production line
The cost of the equipment needed for manufacturing
Which of the following will have the greatest impact on the environment during its lifetime of use?
A plastic garden table and chairs
A wooden garden table and chairs
Which of the following has the minimum impact on the environment, at the end of a product's life?
Which of the following products is the easiest to reuse, rather than needing to be recycled?
Aluminium food dishes
Which of the following is an advantage of recycling plastic bottles?
Prevents the release of toxic gases from landfill sites
Reduces the emission of greenhouse gases
Prevents ozone depletion
Which of the following is a disadvantage of recycling copper?
It has an incredibly high melting point
Copper reacts quickly with oxygen so it is difficult to obtain pure copper through recycling
It can be difficult to separate different metals
Which of the following organisms cannot be used to obtain copper from low-grade ores? - Higher
What factor does the biological extraction of copper, using phytoextraction, depend on? - Higher
That copper compounds are poisonous
That plants can take in copper compounds from the soil
That photosynthesis stores energy in plants
