igus introduces e-chain made entirely of recycled material

Conserving resources and extending the product life cycle — this is the goal igus is pursuing with the new E2.1.CG cradle-chain

This cradle-to-cradle principle of the circular economy, which is based on nature, aims to return consumer goods to the biological or technical cycle, in order to conserve valuable resources and raw materials. To pursue this goal, igus has developed the world’s first energy chain made from recycled material on the basis of its own chainge e-chain recycling programme.

From extreme weather and natural hazards to marine pollution, the climate crisis is getting worse and more people are becoming aware of it.

“Even the purchasing decisions of our customers are increasingly being shaped by ecological considerations. That is why we have put a lot of effort into product development in order to be able to produce more resource efficiently — without sacrificing product quality,” explained Jörg Ottersbach, head of the igus e-chains business unit.

The result is the E2.1.CG cradle-chain — a complete range of e-chains made from the new igumid CG material. Numerous tests in igus’s own test laboratory show that the new e-chain has almost the same technical properties and load limits as an energy chain made from the standard igumid G material. Another advantage is that the cradle-chain is available at the same price as e-chains made from the standard material. The new range is available from stock in five series and 28 chain types.

From discarded e-chain to recycled material

The cradle-chain uses, among other things, recycled material from the chainge recycling programme. As part of this programme, igus has been collecting used energy chains from customers since 2019 so they do not end up in industrial waste. This service is offered for both igus e-chains and chains from other manufacturers. So far, more than 32 tons of material has been collected across 13 countries. For 2022, igus has set itself the goal of increasing this total to 500 tons. Scrap material is sorted by type, cleaned and processed to new quality. This is possible with the help of a chemical analysis and formulation tuning — a process in which material is optimised for the desired properties and therefore enables constant product quality. The post-consumer material igumid CG is then used to make the recycled cradle-chain — without any loss of quality in terms of wear behaviour, stability or bending fatigue.

Sustainable raw material cycle — with 28% less CO2

With the new e-chain product range made of recycled material, igus is making a further effort to conserving resources and advancing the circular economy. According to the environment product declaration, this sustainable raw material cycle also reduces CO2 emissions by 28%.

Ottersbach said: “The focus should not be only on first use of products, but also the reuse of raw materials. We see a lot of ‘cradle-to-cradle’ potential and strive to reprocess as many raw materials and discarded products as possible so that precious resources are not waste, but used wisely for as long as possible.”
