when we wash our clothes we use

detergents these remove the grime sweat

and stains that we pick up in everyday

usage however at what cost

each time you use detergents there is an

environmental impact

first what chemicals or substances make

up a soap powder or a liquid do you know

any pause the video and resume when

ready

the chemicals used to achieve stain

removal and whiter than white cloves are

a complex mixture containing surfactants

which allow the water and the greasy

stains to mix making stains removable

soap powders or liquids are often basic

to help disrupt chemical bonds

neutralizing acids and so make the

surfactants job easier there are also

enzymes biological agents which break

apart fats proteins and starch found in

food stains fragrance chemicals are

added to give your clothes that fresh

smell whilst bleaches containing

peroxides or fluorescent whiteners give

your clothes a renewed brightness

yet before the detergent makes it to a

washing machine it has to be

manufactured and that's where the

environmental concerns lie you may have

heard the idea of carbon footprints if

not then check out the video on this

channel

it's estimated that for every mile an

average car travels half a kilogram of

carbon dioxide is emitted

in america families on average do 300

loads of laundry per year

this means that the carbon footprint of

laundry detergents for one year of

laundry is approximately

218 kilograms per year

while this seems low this only factors

in the detergents use and not the energy

usage of the washing machine or drying

appliances

when you consider all of the families

across the globe that use detergents the

carbon dioxide footprint is considerable

secondly the chemicals found in washing

detergents cause problems

if they end up in rivers or streams

can you think what the issue might be

pause the video and when you have an

idea resume an answer is that the

chemicals found in detergents are toxic

to aquatic organisms

one such chemical is phosphate found in

many washing powders and this causes

eutrophication

this is when an increased amount of

phosphate leads to greater numbers of

plant and algal material building up in

rivers or lakes the problems start once

the plants die

the bacteria that feed off the decaying

plant and algal material uses the oxygen

dissolved in the water

the reduction in the amount of dissolved

oxygen leads to changes in the types of

species in the lake for example

commercially and recreationally

desirable fish such as trout are

replaced by undesirable fish such as

carp because they have a higher

tolerance to lower dissolved oxygen

levels or can result in no fish at all

due to these environmental concerns

eco-conscious consumers have called for

the development of green detergents it's

now possible to buy detergents that do

not contain perfumes or dyes and they're

typically phosphate free and

biodegradable

in addition they're designed to work in

cold water can you think why

pause the video and resume when you have

an answer

the answer is that using a washing

machine on a cold setting prevents

electricity being used to heat the water

and so minimizes the carbon footprint

for each wash cycle

other environmental approaches also

include using concentrated formulas this

is so less packaging is used in the

manufacture of the soap boxes or cartons

and also reduces shipping and or

trucking costs to move the shipment as a

result this uses less oil
