Sustainability

Meeting the needs of the present without compromising the ability of future generations to meet their own needs.

(World Commission on Environment and Development, 1987)

Consumption

By 2050 at current consumption rate we will need:

8.5 planets to absorb our carbon dioxide emissions

6 planets worth of steel

3.5 planets to sustain cement supply

3.5 planets to meet current timber demand

‘Spaceship Earth’

Design for the challenge of sustainability in the 21 st Century

Global annual production of plastics

1973 1 million tonnes

2003 150 million tonnes

93% of production materials are never used in the final product

80% of products are discarded after a single use

What do we throw away?

What do we throw away?

Annually, in the UK:

•We produce more than 434 million tonnes of waste

•Each person throws away about 500kg of rubbish

•The average family consumes around 330 glass bottles/jars

•The average household throws away 675 cans

•The average household throws away 208kg of waste paper

•Each person consumes 1 tonne of wood

(wasteonline.org.uk)

What do we throw away?

What do we throw away?

Glass

The average glass bottle contains over 25% recycled glass

80 million fluorescent lighting tubes go to landfill each year

Plastic

Every year, an estimated 17 billion plastic bags are given away by supermarkets

This is equivalent to over 290 bags for every person in the UK.

Oil

1 litre of oil can pollute 1 million litres of fresh drinking water

(Scottish Oil Care Campaign).

What do we throw away?

Wood

The UK consumes about 3% of global wood consumption with only about 1% of the worlds population.

Batteries

20,000 batteries are landfilled every year in the UK.

It can take up to 50 times more energy to produce a battery than it actually delivers.

Textiles

25% of textiles are currently recovered.

Of these 43% become secondhand clothing,

12% wiping clothes, 22% filling materials, 7% fiber reclamation,

9% are shoes which are reused

7% is rejected as waste

Britain only recycles 2-4% of its clothing

Recycling - problem solved?

Recycling - problem solved?

Recycling 1kg of aluminium saves:

up to 6kg of bauxite

4kg of chemical products

14 kWh of electricity.

Recycling aluminium requires only 5% of the energy produces only 5% of the CO

2 emissions compared with primary production

In 1989 2% of all aluminium cans in the UK were recycled

In 1998 36% of all aluminium cans were recycled

Recycling 1 tonne of steel saves:

1.5 tonnes of iron ore

0.5 tonnes of coal

40% of the water required in production

75% of the energy

1.28 tonnes of solid waste

Reduction of air emissions by 86%

Reduction of water pollution by 76%

Recycling 1 tonne of paper saves:

at least 30000 litres of water

3000 - 4000 KWh electricity ( a 3 bed house for 1 year)

95% of air pollution.

Provides choice, not a way of making comparisons of sustainability

What is ‘material’?

Material life cycle

So… materials have a story materials have a journey materials have a lifecycle

What can we learn by uncovering this lifecycle?

Material life cycle

1.

Acquiring raw material

2.

Processing & manufacture

3.

Packaging & distribution

4.

CONSUMER USAGE

5.

End of life disposal

What makes a material ‘not eco’?

1.

Acquiring raw material

2.

Processing & manufacture

3.

Packaging & distribution

4.

CONSUMER USAGE

5.

End of life disposal

1.

Irreplaceable, hard to extract

2.

Polluting & generates waste

3.

Source far from market, needless marketing led packaging

4.

Short product life

5.

Landfill

What makes a material ‘eco’?

1.

Acquiring raw material

2.

Processing & manufacture

3.

Packaging & distribution

4.

CONSUMER USAGE

5.

End of life disposal

1.

Easy access, quickly renewable

2.

Low energy manufacture & no waste or pollution

3.

Local, unpackaged

4.

Long life cycle, non toxic, needed in small quantities, not fad

5.

Bio degradable, reprocessable, kept from waste stream

What would the most ‘un-eco’ material possible be like?

• Limited supply

• Large scale permanent social, cultural & environmental damage & instability

• Forced low wage labour to produce

• From very far away

• High embodied energy in extraction & processing

• Polluting manufacturing process

• Heavily over-packaged un-necessarily

• Produced in excess

• Toxic in use

• Combined with other materials so un-recyclable

• Produced to satisfy a stylish/fashionable fad (prematurely replaced)

• Decomposes very slowly

• Waste & pollution at every stage of life

What would the most ‘eco’ material possible be like?

• Comes from just beyond your front door

• Quick growing

• Low embodied energy

• No waste produced in converting from raw to useful

• No need for additional packaging

• Non polluting & non toxic

• Useable effectively on its own

• Available cheaply

• Available in quantities to fulfill demand

• Bio degradable

Eco material specification

• You must be guided by a lifecycle analysis approach to design

• Trade offs are inevitable as there are no easy answers

• It is impossible to accurately measure relative ‘eco-ness’ of materials

• Learn an informed, intuitive approach to material assessment

• Decisions must be based on broad but extensive knowledge

• You must be willing to constantly update your materials knowledge as new information & materials arrive

Aim for ‘BEST POSSIBLE’ not just ‘BETTER THAN’

Criteria will include…

Eco material specification

Question the supplier & gauge their commitment to ‘eco’ issues

• What environmental information do they provide about their goods?

• Do they generally provide information gladly or reluctantly?

• Ask for environmental & health / safety data

• Are they working towards less harmful alternatives?

• Can they trace their goods back to origin?

• Are their goods certified in any way?

• Do they have an Environmental policy?

• Do they have a Health & Safety policy?

• Do they have an Ethical or Social policy?

Red (green?) herrings

• Eco friendly

• Longer lasting

• Kinder to the environment

• Natural / as nature / home made

• Economical

• Less polluting

• Recyclable

• Inspired by nature

• etc etc…

All the above refer to ‘BETTER THAN’ not ’BEST’
