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

Question 2

Question 3

Answer 3

not able to be dispersed, goes into the atmosphere

Question 4

designing out waste

Answer 4

using all resources w maximum efficiently throughout design => minimum waste

Question 5

5 key principles of designing out waste

Answer 5

1 reuse + recover materials
2 material optimisation
3 waste efficient supply
4 off site construction
5 deconstruction

Question 6

dematerialization

Answer 6

reduction of total material and energy used on product with no damage to functionality

Question 7

product recovery strategies at the end of life

Answer 7

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

Question 8

circular economy

Answer 8

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

Question 9

linear economy последовательность

Answer 9

take resource, make product, dispose it, produce waste throughout

Question 10

circular economy последовательность
