Teijin Aramid Twaron fibers cut energy consumption by 20%
Jun '14
The use of Twaron aramid fibers can reduce energy consumption by 20%, while reducing CO2 emissions by more than 100,000 tons per year. That’s what Teijin Aramid’s Customer Benefit Model (CBM) shows in a case in which the use of steel-wire hoisting ropes is compared with that of synthetic Twaron hoisting ropes in a specific deep-mining application. The Customer Benefit Model (CBM) – developed by Teijin Aramid – calculates which financial and sustainability-related benefits the use of Twaron offers in a specific application. 
In deep mining (at depths of more than 2,000m), the weight of steel ropes has a significant effect on energy use during hoisting. Synthetic hoisting ropes using Twaron aramid fibers have the same strength per diameter as steel ropes, but at 20% of the weight.
This means that, in a shaft, the same payload can be hoisted using less energy, causing fewer CO2 emissions and resulting in lower costs. And because no greasing is needed, maintenance costs are also reduced. 
In recognition of the value of this development, a consortium has been formed with Canadian mines, the Canadian government, a US rope manufacturer, a consultancy company and Teijin Aramid as fiber supplier. This consortium has developed case studies comparing steel wire ropes with synthetic Twaron ropes for different situations.
To develop and explore this new technology further and to fund test facilities, the consortium is now seeking financial support from other industry partners who are interested in participating in the next phase of the mine hoisting rope project, which will take place in 2014.
Sustainability Report 
The deep-mining case is one of the highlights in Teijin Aramid’s Sustainability Report 2013 that was published.
