2.2 Flashcards
several strategies to reduce/eliminate waste in product lifecycle
1 repair – fixing/renewing a broken component so product potentially can be used forever
2 recondition – rebuilding a product so that it is “as new”
3 recycle – using materials from obsolete products to create new products (not totally green bcs uses heat)
4 reuse – utilising the object more than once
5 re engineer – redesign components to improve their characteristics/performance
waste
trash that is being dumped everywhere. bad for animals, intoxicates waterways
pollution
not able to be dispersed, goes into the atmosphere
designing out waste
creating products that minimize waste generation throughout their lifecycle
4 methodologies for designing out waste
1 prevention, monitoring of waste
2 product recovery strategies at end of life
3 circular economy (waste = resource)
4 designing green products
dematerialization
reduction of total material and energy used on product with no damage to functionality
product recovery strategies at the end of life
1 recovery of standard parts
2 recovery of raw materials
3 energy recovery – energy production by treating non recyclable waste
4 WEEE recovery – WEEE is a mixture of materials from electrical products that can be hazardous if not managed properly => improving recycling of these materials
5 recycling
circular economy
model in which resources remain in use for as long as possible; products + materials are recovered at the end of product life – waste is viewed as a resource, is brought back into the system
recycling
using materials from obsolete products to create other products
WEEE
mixture of materials from electrical products w a hazardous content, if not properly managed can cause environmental and health problems
LCA
technique to assess environmental impacts associated with all the stages of a product’s life from cradle to grave
