  • 1. CARBON FOOTPRINTS IN TEXTILE NISHANT CHHABRA 10TXCH30
  • 2. WHAT IS CARBON FOOTPRINT The total sets of greenhouse gas emissions caused by an organization, event, product or person. Wright, Kemp, and Williams, writing in the journal Carbon Management, have suggested a more practicable definition:
  • 3. CONTD… A measure of the total amount of carbon dioxide (CO2) and methane (CH4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system or activity of interest. Calculated as carbon dioxide equivalent (CO2e) using the relevant 100year global warming potential (GWP100)
  • 4. WHY IT IS NECESSARY Climate changes characterized as global warming are leading to large-scale irreversible effects at continental and global scales. TODAY CARBON FOOTPRINT = GLOBAL WARMING
  • 5. CARBON FOOTPRINTS IN ALL INDUSTRIES
  • 6. LAYERS OF CARBON FOOTPRINTS Primary footprint - monitors carbon emission directly through energy consumption - burning fossil fuels for electricity, heating and transportation, etc. Secondary footprint- relates to indirect carbon emissions (Life cycle of products and Sustainability).
  • 7. HOW TO CALCULATE CARBON FOOTPRINTS Calculation of carbon foot prints totally depends on type of energy used types of natural resources and size of any organization.
  • 8. NEED OF CARBON FOOTPRINT AUDIT IN TEXTILE INDUSTRY The Textile Industry in India is expected to grow from an estimated size of US$ 70 billion today to US$ 220 billion by 2020, which would proportionately increase impact on our Carbon Footprint.
  • 9. CONTD…  In 2008, annual global textile production was estimated at 60 billion kg of fabric. The estimated energy and water needed to produce such quantity of fabric is considered to be: 1,074 bn kWh of electricity 132 mn MT of coal. about 6-9 tn liters of water. Thus, the thermal energy required per metre of cloth is 4,500 - 5,500 Kcal and the electrical energy required per metre of cloth is 0.45 - 0.55 kwh.

  • 12. APPROACH TO REDUCE CARBON FOOTPRINT IN PRODUCTION Substituting Organic fibres for conventionally grown fibres Modern machines and equipments helps to reduce carbon emission Optimize process sequence Usage of chemicals and dyes Waste water treatment

  • 17. WAYS TO REDUCE CARBON FOOTPRINTS IN GMU  Use of metals such as chrome, cadmium, lead, nickel and other heavy metal residues are considered unfriendly to the environment, since these metals release residues that are harmful to the human skin.  Recycling of small pieces of waste fabrics into shoddy items and/or wipe clothes in the unit.  Co-ordination between design and production department  Biodegradable materials should be preferred against synthetic materials.  CAD and CAM systems can be used to gain optimum fabric utilization.
  • 18. INDUSTRIAL APPROACH
  • 19. Suggestions for general resource usage Car pool system or keeping office vans for certain routes can be set up for work. Keeping tyres properly inflated increases the efficiency of fuel. Turning off the vehicle’s engine at red light saves 20% of the fuel. Avoid large number of flights as air transportation has a largest carbon footprint than any other means. Prefer making conference calls. Dimmer switches which reduce energy consumption by up to 20% can be installed.
  • 20. SUMMARY In the present times when global warming is a major issue worldwide, it is our responsibility reduce our contribution to carbon footprints. Besides reducing waste and consequent reductions in air and land pollution, it will lead to number of individualized benefits. It will allow textile industry to demonstrate their commitment to reducing their negative impact on the climate and the planet.
