Presentació bamboo

  2. 2. Environmental degradation is the deterioration of theenvironment through depletion of resources such as air,water and soil, the destruction of ecosystems and theextinction of wildlife.
  3. 3. Bamboo textiles are cloth, yarn, and clothing made out of bamboofibres. In recent years a range of technologies have been developedallowing bamboo fibre to be used in a wide range of textile andfashion applications. Modern bamboo clothing is made from either100% bamboo yarn or a blend of bamboo and cotton yarn, or othertextile fibres.
  4. 4. GrowthBamboo reaching up to 35 meters tall is the fastest growing woodyplant in the world. There is bamboo in diverse climates from coldmountains to hot tropical regions.
  5. 5.  GrowthAbout 40 million hectares of the earth are covered with bamboo,mostly in Asia. These facts make bamboo a sustainable and versatileresource.
  6. 6.  HarvestingOnce a new shoot emerges from the ground, the new cane willreach its full height in just 8–10 weeks. Each cane reaches maturityin 3–5 years. Bamboo can be continually re-harvested with nodamage to the surrounding environment. It regenerates after beingcut just like a lawn without the need for replanting.
  7. 7.  Yield and land useBamboo can be used as food, fibre and shelter and due to its ease ofgrowth and extraordinary growth rate is a cheap, sustainable andefficient crop. Yields of bamboo greatly exceed the yield of mosttrees and needs little care and maintenance.
  8. 8. Greenhouse gases and global warmingBamboo minimizes CO2 and generates up to 35% more oxygen thanequivalent stands of trees. One hectare of bamboo sequesters 62tones of carbon dioxide per year while one hectare of young forestonly sequesters 15 tones of carbon dioxide per year.
  9. 9.  DeforestationBamboo planting can slow deforestation, providing an alternativesource of timber for the construction industry and cellulose fiber forthe textile industry. Bamboo doesn’t need replanting.
  10. 10. Water useVery little bamboo is irrigated and there is sound evidence that thewater-use efficiency of bamboo is twice that of other trees. Thismakes bamboo more able to handle harsh weather conditions suchas drought, flood and high temperatures.
  11. 11.  Soil erosionYearly replanting of crops such as cotton leads to soil erosion. Theextensive root system of bamboo and the fact that it is not uprootedduring harvesting means bamboo actually helps preserve soil andprevent soil erosion.
  12. 12. BiodegradableAs a natural product derived entirely from plant cellulose, bamboofibre is biodegradable in soil by micro organisms and sunlight.Clothing made from bamboo can be composted and disposed of inan organic and environmentally friendly manner.
  13. 13.  BiodegradableSynthetic fibressuch as nylon andpolyester are notbiodegradable andremain in landfillfor longer.
  14. 14. Pesticides and fertilizersBamboo doesn’t need pesticides or fertilizers for growing.Bamboo also contains a substance called bamboo-kun, anantimicrobial agent which gives the plant a natural resistance topest and fungi infestation. However, the finished bamboo fabricdoes not retain this antibacterial property.
  15. 15. • The growth cycle of bamboo is utterly sustainable.• Bamboo thrives naturally without using any pesticidesor fertilizers.• Bamboo fibre is 100% biodegradable.• Bamboo is the fastest growing plant in the world.
  16. 16. • As a grass, bamboo is cut, not uprooted, helping soilstability.• The yield you get from an acre of bamboo is 10 timesgreater than the yield you get from cotton.• The water requirement for bamboo is little, mainly justfrom what falls. As opposed to cotton, whose waterrequirement per shirts-worth is very big.
  17. 17.  Calculate the amount of clothes that you buy when the season changes.  Calculate the average price of the expense involved in these clothes.  Calculate also the emissions of co2 when these clothes are manufactured.  Calculate now how much the same amount of clothing made ​from bamboo would cost. Consult internet to look for prices.  Calculate also the cost of co2 when these clothes are manufactured with bamboo fiber.  Finally, calculate the percentage saved. After some time, is it better to buy clothes manufactured withbamboo fiber?
