Waste and recycling



Too

much?

Where does all

the waste come

from?

The 400 million tonnes

of waste produced in

the UK each year comes

from a variety of

sources.

Waste is …

Something which is no longer useful to

people.

In the UK we throw away 25 million

tonnes of household waste every year

That’s nearly 350 kilos of waste for

every person!

How many times of your body weight is

that?

What do you throw away?



Plastic

wrappers,

…..?

The effects?

Throwing away this much waste uses up

precious resources.

Much of our waste is made from finite

resources – materials that once used

cannot be replaced – which are they?

Also more energy can go to make new

materials than reuse old ones – so

throwing them away wastes energy –

which might they be?

More effects

83% of household waste end up in landfill sites

They look bad, take up space and attract

vermin.

Toxic substances accumulate, e.g. chemicals

from batteries

9% of waste is incinerated. But this pollutes

the air and there are worries about plastics

releasing toxins into the air.

However, as we saw last week, better methods

of releasing energy from waste will become

more important.

But instead of burying or burning …

What about recycling?

Currently we recycle about 8% of our

waste

It could be as much as 70%

Link the word recycling with each of

these words

– Resources

– Energy

– Pollution

– Sustainable development

Recycling glass

Reduces waste

Saves energy

It takes 20% less energy to produce bottles

from recycled glass

There are 150 000 bottle banks nationwide in

the UK

Do you use them?

Or do the refuse men take your bottles away

separately

Of 6 billion bottles used in the UK, 29% are

recycled

How many bottles per person are recycled?

Recycling aluminium

It costs a lot to produce because it uses

LOTS of energy

Recycled aluminium takes 95% less

energy and causes 99% less pollution

that production it from bauxite rock.

Of 5 billion aluminium cans produced , 1.6

billion are recycled

So 3.2 billion, worth £24 billion as scrap

end up in land fill!

Look at what the rest of the EU

are doing?

Most of the recycled stuff ends

up in landfill anyway

(Source: West Oxford District Council press release August 2006)

GLASS - 70% of glass is sold to the UK glass industry

and recycled for bottle making and fibreglass

manufacture. A small amount is used in road aggregate

(WODC glass goes to a recycler in West Yorkshire).

The other 30% goes to the European glass market,

mainly to Italy, France, Spain and Portugal, making

bottles of a darker green because of having been made

from a variety of colours.

CANS - Our food and drink cans go to South Wales.

The steel is recovered and sold globally. The aluminium

is sold within the UK and made into new drinks cans.

The process of recycling used drinks cans to make new

ones can take as little as 6 weeks from bin to

supermarket.

Most of the recycled stuff ends

up in landfill anyway

CARDBOARD - Our cardboard goes to a processor in

Doncaster where it is recovered, bulked and sold to

paper and cardboard mills. Each time cardboard is

pulped, the fibres get shorter, but even so, cardboard

can be recycled 4 or 5 times. Uses include boxes and

packaging, stationery, and animal bedding.

PAPER - WODC paper goes to Kent where it is made

into newsprint. Higher grade office paper from the

WODC offices is sold on to be made into tissue paper

products.

PLASTICS - Plastics go to a recycler in Lancashire

where mixed plastics make a wide range of products

such as drain pipes, insulation materials, flower pots,

watering cans, and fleece material. Myth - Plastic is

exported to China and dumped in landfill!

Most of the recycled stuff ends

up in landfill anyway

TEXTILES - Textiles from recycling centres are

collected by Cope and taken to their charity shops for

resale. Those not suitable for that are sold to rag

merchants. Materials collected at the kerbside are

sent as second-hand clothes to the third world. Other

materials are baled and produce wiping cloths or sold

to make insulating material and other products.

Fabric Facts

(Source: CAG Oxfordshire Newsletter October 2006)

Nearly 70% of items put into clothing banks are

reused as clothes. Any unwearable items are sold to

merchants to be recycled as factory wiping cloths.

NoLoGo are a team of volunteer designers set up by

Oxfam who restyle donated garments and fabrics,

selling them on at some Oxfam shops.

Most of the recycled stuff ends

up in landfill anyway

At least 50% of the textiles we throw away are

recyclable.

If everyone in the UK bought one reclaimed woolen

garment each year it would save an average of 371

million gallons of water and 480 tonnes of chemical

dyestuffs.

It is estimated that more that 1 million tonnes of

textiles are thrown away every year, with most of this

coming from household sources.

Unwearable trousers, skirts, etc are sold to the

'flocking' industry which shreds them for fillers in car

insulation, roofing felts, loudspeaker cones, panel

linings, furniture padding etc.

Over 70% of the world's population use secondhand

clothes.

Recycling in Third World Cities

Urban waste is a serious health risk to the

slum dwellers and squatter settlers who make

up about 40% of the developing world's urban

population of 1.1 billion, according to Carl

Bartone, a senior project officer for the

Integrated Resource Recovery Project at the

World Bank.

Many of these squatters live near garbage

dumps, and some live literally on top of them.

The cities face difficulties in collecting and

disposing of wastes, although they spend as

much as 50% of their operating budgets on

solid-waste management.

Zabaleens in Cairo

Now, innovative waste-management solutions are

emerging that help provide jobs, improve living

conditions, and protect the environment.

In Cairo, some 30,000 Zabaleens (Coptic Christians

from southern Egypt) make up a network of well-

organized and highly efficient garbage collectors.

A pair of Zabaleens working with a horse-drawn

carriage can collect garbage from 350 households in a

day.

After sorting the garbage, the collectors will feed the

edible garbage (about two-thirds of the total) to pigs

and goats to fatten them for market; sell pig droppings

and human excrement to farmers for fertilizer;

and sell scrap metal, glass, paper, and plastics to

middlemen, who then sell the materials to craftsmen.

"Zabaleens make

as much as

three times the

average income

in Cairo," says

Bartone.

"In many developing countries, up to 2% of the

population is supported directly or indirectly

by refuse from the upper 20% of the

population.”

Private garbage collectors and sorters also

benefit from recycling. Mexico's Juarez City

Co-operative of Materials Recoverers,

established in 1975, recovers and sells

approximately 5% of the waste stream. In

1984, the cooperative had sales of $31 million,

compared with only $6.3 million in operating

costs.

In addition, sensible waste management creates energy

in the form of biogas and provides raw material for

such inexpensive products as water pipes, beverage

containers, buckets, lamps, stoves, and sandals.

The Integrated Resource Recovery Project,

established by the United Nations Development

Programme and the World Bank in 1981, aims to

demonstrate appropriate solutions that would enable

cities to improve their waste-management capacity and

make better use of limited financial resources by

recovering the value inherent in wastes.

Resource-recovery methods that the IRRP has studied

include using waste water as refill material to reclaim

low-lying swampland and using treated water for

irrigation and fish cultivation.

Homework

In google put

(your council area) news waste recycling

Pick a story from the news

Write a brief summary of what the story is about and

comment on it – I chose this because ….

I tried Powys – for me and I also tried GLC for London

Those of you not in the UK, either use the local area

where you live – which will mean the local language – or

if you prefer, choose a place in the UK that you know

quite well – your choice
