unit 15 Flashcards
(50 cards)
carbon footprint
measures the impact of greenhouse emissions.sum of all emissions caused by your activities in a year
how can we offset co2 emissions
planting trees
use electric vehicles
choosing renewable energy
plastics
waste plastic is a big problem
low cost and durable
effects of climate change
melting sea ice
desertification and loss of habitats
extreme weather conditions
effects of deforestation
habitats are lost
deforestation leads to soil erosion and flooding
linear economy
works on the principles of take, make and dispose.
often from finite resources
not made to be recycled,reused
simply disposed at end of life
the natural answer
lion king
works in a circular way
plant grows from seed
animals feed
seeds are spread as droppings
predation enables supply of energy for animal to animal
circular economy
rethink the way we make and use products to re-balance our consumption.
designing products can be maintained
manufacturing using renewable or alternative energy
using sustainable or recycled materials
fairtrade
about better prices, better working conditions fait terms for farmers and workers in less economically developed countries
little sun
founded in 2012 objective to bring back solar energy to those who are without electricity
why is solar energy good
reduces energy costs and co2 emissions
brings social,medical,educational benefits
affordable energy
cradle to cradle(c2c)
new approach to design and manufacture that fits into the ethos of the circular economy.
reuse any waste
holistic approach to design
reduction in carbon footprint
cleaning any waste water
elimating use of toxic materials
smile plastics
uses 100% recycled plastic waste to produce new materials
people power
launched a crusade against the use of single use plastic products
materials matter
limiting use of finite resources
designing products with lower integrated materials
processing materials using sustainable energy
recharge
battery technology developing in ways to reduce impact on the environment
replacing disposable batteries
pack it in
consider amount of packaging used to contain products
sorted
products should be manufactured in a way that makes them easy to disassemble to easily recycle them
life cycle assessment
Extraction(resource)
production(transformation assembly)
distribution(logistics transport)
use(operation maintenance reuse)
recycling (end of life)
advantages of global manufacture
greater flexibility
utilise greater manufacturing facilities abroad
economic savings due to lower abroad costs
access to larger workforces
renewable energy
comes from sustainable sources which create little/no waste/pollutants
do not release co2
will never run out
solar energy
first photovoltaic cells(1839)
1958 photovoltaic panels
further products developed increased efficiency and lowered cost
wind energy
1887 windmill for electricity
1991 first wind farm
hydroelectric power (HEP)
dammed/flowing water fed/pumped through pipes that drive water turbine and generator.
