Transcripts

think about you know your smartphone or

a laptop today you know everything about

it every chip in it you know where it

was produced and then you don't know

anything anymore he wastes happens

because objects are no longer useful to

us so we throw them away we exacerbate

that problem by the fact the way we've

engineered them a design that makes it

very difficult to take them apart

extract the useful materials use them

[Music]

four thousand people plus work in here

along here about 15 years now

we found that most of them had elevated

levels of heavy metals in their blood I

think not only Africa is dealing with

these Buist issue because literally

analytical devices are part of our daily

life we simply can't provide these kinds

of products for the seven eight nine

billion people that will be on the

planet in the future if we're throwing

muscle in a way after the dnews for two

or three years

[Music]

suddenly cannot generalize and we're

thinking about a ways is different if

you think about an old CRT monitor if

you think about the modern contemporary

smartphone but certainly there's a lot

of value you can also get back from

e-waste and you know that should be an

incentive to recycle I'm a professor at

MIT we're running place called sensible

city lab and also design office called

cavity search attic we started looking

at this with a project we called trash

it was a few years ago and we work with

the city of Seattle and put many

electronic tags into ways to follow

waste you know we followed banana peels

we follow the all CRT monitors computers

at cartridges and so on a lot of us

would end up at the borders of the

United States then we couldn't form it

anymore

[Music]

[Laughter]

[Music]

the first day I got here our shop you

see the kind of work people are doing

they cut themselves they expose

themselves to so many things my name is

Bennett not a Khufu

I'm a project manager for green advocacy

Ghana so the boys here normally go

around with trucks they go to each home

if they come to my home they will

definitely buy a fruit for me

then you bring all the way here they cut

it into pieces they get aluminum from

the casing they get copper from the the

motor found inside the fridges so what

they do is cut it with a hammer and a

chisel then the cables found in them

they would burn to extract copper then

what happens to the styrofoam it is used

as some kind of fool so if they need to

process other kind of metals to add a

styrofoam and set it ablaze with the saw

we all know is highly contaminated and

the levels of lead cadmium arsenic in

the soil keep on rising we did a health

survey of people here we found that most

of them had elevated levels of heavy

metals in their blood heavy metals is

linked to cancer and other diseases you

know this whole place is like commercial

district

you have people selling what drinks

others working others going around

taking stuff from the floor so it's a

whole community on its own

out here there are about 4,000 people

plus working here and most of them spend

the whole day here so a lot of them will

be exposed

[Music]

most people see a Belushi as a waste

dump but as a service they are rendering

to ordinary ghanians yes it's it's bad

but it's a service we need if Belushi

didn't exist what would happen to our

old vehicles our old refrigerators TV

sets and all that we've always had the

missional idea of trying to connect

people to technology right through

design hi I'm Tim Brown and I'm the CEO

of the design company idea back in the

early days when we started we did things

like the first Mouse for the original

Macintosh computer and the first laptop

and the first automatic defibrillator

the complexity of the systems that

support these products and services we

understand that so much better now which

is why we got interested in things like

the circular economy and the need to

think about products not only through

their cycles of use but what happens to

them afterwards I am Vincent ability'

and minister of environmental for the

Republic of London we were dealing with

tin

thousand tons of e-waste every year and

we decided to put in place any wastes

this muttering and a second plant which

has the capacity to deal with these ten

thousand tons every year

today in Rwanda our second plant first

of all II furbishing goodness on

computers or fighters in 5400 in

theaters which have been distributed to

schools but we are sending plastic parts

the plastic components between plastic

recycling companies we are sending the

metal parts to steel industries but we

are planning on a second phase to

recover the precious metals which are

part of these electronic devices

[Music]

with the help of PRF a us-based NGO we

decided to find a way of eliminating

burning as a means of copper extraction

so we set up this pilot site here with

wire strippers and you see these holes

where you push the cables to - these are

the sizes of cables we can recycle and

it does that within seconds when I

started so plastic goes one side the

metal comes out the other side

when you bring your cable here is clean

copper or aluminium which weighs more so

the boys will tend to have a lot more

money

[Music]

it's caused by design and the solutions

are a design problem if we really are

serious about a central economy we want

to close the loop create new notions of

of supply we don't need to use or very

many devices having certain components

that have many lives and when we need to

dispose them off we just make sure we

disclose them of where they need they're

there are facilities we're still in love

a little bit with the idea of beautiful

products that we want to own that maybe

that's not the right model for the

future it could be that we shouldn't be

buying these products at all but we

should be taking them as services so

that the manufacturers have a real

reason to take them back we're gonna

have to be quite creative over the next

few years in order to solve these

problems
