Recycling Flashcards
why is it important to conserve fossil fuels
- because they are running out
- and burning them contributes to acid rain and climate change
what does the extraction of raw materials lead to the burning of lots of fossil fuels
- because it can take lots of energy
- which leads to the requirement of burning lots of ofssil fuels
why does recycling material save energy
the process often only uses a small fraction of energy needed to extract and refine the material from scratch
why is it important to recycle materials that are rare
- because there is a finite amount of them
- and many of them are non-renewable
what are the disadvantages of using mines
- they are damaging to the environment
- they destroy habitats
- they are aesthetically unappealing
why should we recycle materials if we dont like using mines
because recycling materials means that we dont have to use them as much
how does recycling benefit the economy
- it saves money as the extracting requires more energy than refining
- recycling materials that are expensive to extract or buy can be particularly beneficial
what is an advantage that comes with recycling in terms of jobs
- it is a massive industry that creates lots of jobs
- the materials to be recycled need to be transported to and processed at recycling centres
- they then need to be reprocessed into new products which can be sold
- jobs are created for every stage of this process, far more than disposing of waste in landfill
what would be the direct effect of not recycling aluminium and how much ore would you need to mine
- you would need to mine more aluminium ore
- 4 tonnes for every 1 tonne of aluminium you need
what disadvantages come with the mining of aluminium ore
- you make a mess of the landscape as they are often in rain forests
- the ore needs to be transported and the aluminium extracted which uses lots of electricity
- then you have the costs of sending the used aluminium to landfill
what is the effect of every 1kg of aluminium cans you recycle
- you save about 95% of the energy needed to mine and extract fresh aluminium
- you save 4k aluminium ore
- and prevent a lot of waste
