THE TREND [1]


1990s

2000s

2010s

Lean manufacturing, ISO driven quality practices

Ethical sourcing and labour practices

Sustainability and optimally using natural resources

What the WEST is doing?


Indian Scenario

• Trends travel east…

• Sustainability practices: mandatory!

• No quantitative approach to measure work done in this direction.


“You can’t manage what you don’t measure!”

Objective


Primary:•To adapt a GHG Emission calculation tool for the Indian Apparel Sector.

Secondary:• To study the work processes of apparel industry with focus on energy sources.

• To design an Excel based tool and its user manual.

• To road-test the tool.

Research Process Flow

• Ratification of the tool by TERI

• Road-test the tool. Find out the problems faced by the user. Amend changes.

Fuels Combustion(e.g. boilers, furnaces or turbines)

Owned Transport(e.g. trucks, trains, ships,

airplanes, cars)

Process Emissions(e.g. cement,aluminium, waste

processing)

Fugitive Emissions(e.g. air conditioning &

refrigeration leaks, methane leaks from pipelines)

Scope 1: Direct

Consumption of purchased

electricity, heat, steam and cooling

Scope 2: Energy Indirect

Purchased materials and fuels(e.g. extraction, processing

and production)

Transport-related activities(e.g. commuting, business

travel, distribution)

Waste disposal(e.g. waste, recycling)

Leased assets, franchising and outsourcing

Sold Goods and Services (e.g. Use of goods and services)

Greenhouse Gases

• Departments where gases are emitted:

Gas

CO2

CH4

N2O

SF6

Hydro flourocarbons (HFCs)

Emission areas in apparel mfg unit

All departments consuming electricity, transport of fabric, garments, boilers, gensets

Boilers, gensets

Boilers, gensets

Circuit breakers

Air conditioners, refrigeration, heating equipment


• Sufficient of work done in other sectors such as Cement industry, Power sector, Aviation and Telecom

• Absence of standard, reliable, accurate way of calculating the GHG emissions from Apparel Sector

• Lack of bottom-up GHG inventory building approach for the T&A sector.

• The more that our industry works toward a common goal, the more likely we are to develop scalable, viable environmental solutions.


RESEARCH GAP



• The tool calculates the carbon footprint of an apparel manufacturing unit.

• Apart from carbon dioxide it takes into account,– CH4

– N2O

– HFC

– SF6

Summary Sheets Information Sheets

Data Required Before Starting

• Desired Reporting time (Annual/Half/Quarter)

• Quantity of fuel used in boilers, gensets, (litres/kg/metric tonne)

• Company owned vehicles:• Quantity of fuel used //OR// • Distance travelled by each vehicle (kms)

• Refrigerators, ACs heating equipments present in the plant• Number of ACs, refrigerators • Type of refrigerant used in them• Refrigerant charge (kg)


Data Required Before Starting

• Inventory, Sales and Purchase of SF6 used in circuit breakers

• Amount of electricity consumed from the grid in kWh

NOTE: All these data have to be gathered for the reporting period only.


List of Formulae Used

CO2, CH4, N2O (stationary and mobile) emissions= ∑ fuel consumed X Net Calorific Value X Gas Emission Factor (kg) (TJ) (kg/TJ)

CO2 Mobile emissions (Vehicle Km travelled method)

= Emissions = ∑ [Distance travelled X EF]

(km) (g/km)

HFC Emissions=

List of Formulae Used

Converting other gases into CO2 equivalent:

t CO2 e of gas a = (Gasa emissions in tonne) x GWPa


Road test: Findings

• Road test was carried out in 3 export houses based in NCR.

• Findings:– Explanation of each sheet needed in more detail.– Inclusion of air and rail travel emissions calculated.– Need to know the next steps to reduce their emissions.


BENEFITS OF USING THE TOOL

• Establish baseline emissions.• To participate in voluntary or mandatory emission

reduction programmes.• Create GHG inventories through a bottom-up approach• Can be used during LCA of apparel products.


• The same tool can be applied to the textile industry after research into any other greenhouse gases emitted during finishing, dyeing, printing process.

• Methods to quantify emissions from rail, air and ocean transport may be explored.

• Explore the possibilities of storing the data generated from each factory in a centrally located server online to form a comprehensive GHG inventory.

• More features can be added to move up in the hierarchies of a sustainability measurement tool.
