Training Workshop on Green Interior Materials & Products

EIA Environmental Impact Assessment

Aspects

•Environment

•Toxicity / pollution

•Environmental concerns Local to Global

•Sustainability

1.Environmental

2.Social

3.Economic

Environment verses Development




EIA process Intricacies

Associated Factors

•Complexity

•Economic survival jobs / work opportunity

•Importance

•Uniqueness – Different from others

1.Environment friendly

2. Eco-friendly

3.Green product

4. Sustainable Product

Development with Environmental concern




EIA process

Targets

1. Development projects (New or Expansion) - compulsory

2. Processes - Voluntary

3. Activities - Optional

4. Products – Corporate Necessity

Environment - A necessity




EIA study

To collect in depth information about:

• Environmental burdens

Use of resources

Use of Energy

Pollution Loads• Estimate Environmental cost

Economic cost

Health/comfort / well being

Social

• Address Environmental issues

Toxicity

Degradation /alterations

Waste generation

Global impacts




EIA Excersise

objective:

• To make / take decisions

• Identify environmental issues

• Environmental Remediation

EIA Need

What is the need:

• To get Government clearances

• To get registration

• To get accreditation

• To stake claims – Green label, Eco-mark• To market and promote product

• To get Tax and other fiscal benefits

• To improve export of the products

• To improve product design

• To improve products environmental quality

• To improve production process

• To improve energy efficiency

• To find appropriate alternate rawmaterials



EIA Process

Variables:

• Nature of project

• Nature of activity

• Nature of product

• Purpose of EIA

In this workshop focus is on building’s interior products



EIA Excersise

objective:

• To make / take decisions

• Identify environmental issues

• Environmental Remediation



EIA How it is done

Steps

Select a product

Collect base line data

Quantitative inventory of raw materials used

Quantitative inventory of production process steps used Identify environmental issues associated with each material & process

List Environmental issues that are needed to be resolved

Prepare priority list for environmental remediation

Look for alternative raw materials that are environmentally safe

Quantify the environmental costs/indicators/indexes

Normalize the above

Compare the normalized values with benchmarks/standards or

competitors identical product

Draw conclusions



EIA Level of detailing

Example - WOOD

Type of Wood

Source

Denudation of land due to loss of tree

Reduction in primary productionReduction in natural carbon assimilation

Soil erosion

Ground water depletion

Loss of habitat to wild life

Toxicity due to wood processing

Effect of toxicity on human and environmental health

Energy used in the wood processing

Caron footprint of wood processing

Final disposal of processed wood after completion of use full life

Environmental remediation



EIA Environment Reference points

Examples: Pollutants & wastes

Human Health:

Toxicity

Respiratory Organics Carcinogens

Particulates

Climate Change

Radiation

Ozone Layer depletion

Smog formation



EIA Reference points

Examples: Pollutants & wastes

Ecosystem Health

Eco-toxicity

AcidificationEutrophication

Land use



EIA Environment Reference points

Examples: Natural Resources

Resource use /

Resource depletion

Mineral resourcesFossil fuels



EIA Reference points

Examples: Health Effect

Toxicity

Emissions

Concentrations / Half life

Exposure (time duration)

Synergism /Antagonism

Mortality / disability



EIA Environmental Remediation

Reduce burden on Environment: 1.

Reduce material quantities being used in product / production

Process Modification:

Reduce use of water

Reduce use of energy

Reduce waste generation

Reduce toxicity





Replace or change the material being used

Use non toxic material

Use Biodegradable material

Use Materials having low embedded energy

Use recycled material

Use green chemicals





Take care of post life remnant of the product:

Take back the used up material and recycle or dispose in the safest

manner

Compensatory measures:

Tree plantation (carbon sequestering)

Recycle waste materials totally

Use renewable energy
