The current world population is 7.1 billion; this number is expected to grow to 9.2 billion by 2050. The bulk of this growth will take place in underdeveloped and developing countries. As the economy in these countries improves, residents will have more purchase power, so per-capita consumption of goods, including textiles, will increase. In short, population and economic growth will stimulate rapid increases in textile production and consumption, which, in turn, will drive significant increases in the textile industry’s absolute energy use, water use, and carbon dioxide (CO2) and other environmentally harmful emissions.
China is the world’s top textile exporter with 40% of world textile and clothing exports. The textile and clothing industry is the largest manufacturing industry in China with about 24,000 enterprises. China is the largest clothing producer in the world and has the largest production capacity for textile products consisting of cotton, manmade fibers and silk.
The textile industry, in general, is not considered an energy-intensive industry. However, the textile industry comprises a large number of plants which all together consume a significant amount of energy. The share of total manufacturing energy consumed by the textile industry in a particular country depends upon the structure of the manufacturing sector in that country. For instance, the textile industry accounts for about 5% of the primary energy use in manufacturing in China, while this share is less than 2% in the US.
In addition to using substantial energy, the textile industry and especially the wet-processing is one of the largest consumer of water in manufacturing and hence one of the main producer of industrial wastewater. Also, since various chemicals are used in different textile processes like pre-treatment, dyeing, printing, and finishing, the textile wastewater contains many toxic chemicals which if not treated properly before discharge to the environment, can cause serious environmental damage. In addition, in many countries, the charges for water supply and effluent discharge are increasing. Hence, for companies to save cost and remain competitive, they need to save water and address issues related to wastewater disposal.
EAGER Textile tool has been developed by Lawrence Berkeley National Laboratory. EAGER Textile tool allows you to evaluate the impact of selected energy efficiency measures for the textile industry by choosing the measures that you would likely introduce in your facility, or would like to evaluate for potential use. You select the degree or share of implementation for each of the measures, and the EAGER Textile tool will calculate the typical energy savings (electricity, fuel, final, and primary energy), CO2 emission reduction, cost, and simple payback period.
