How sustainable are plastics for movement?

Plastic is a much-discussed material. We know that high-performance polymers can make a contribution to the protection of resources and to the environment, and have made this the focus of our corporate activities.
We look at plastics in three phases: during their production, in use and at the end of the product's life. On this page, we show you our answers to the question of sustainability, both in terms of our products and in everyday life at igus. Not everything has been answered yet, and for some things, especially with regard to sustainable production, we are still working on answers and solutions.

Still to be solved:

  • Emissions of gases and chemicals from the production of raw materials 
  • Abrasion during use 
  • Dependence on the fossil raw material oil


  • By 2025, we want our buildings and production to be CO2-neutral.

Update on the path to climate neutrality

In 2021, we achieved 31.2% less CO2 emissions than in 2020. This figure relates to Scope 1 and Scope 2 emissions. The switch to green electricity in mid-2021 and to climate-neutral gas in October 2021 will play a key role here.

The three phases of plastic

Before ...

Production of plastics and parts

Diagram energy balance steel, aluminium, plastic

Energy balance

The production of 1 m³ of plastic requires around 50% less energy than that of 1 m³ of steel or aluminium.

Graph oil consumption of plastics

Oil consumption

The production of high-performance plastics accounts for just 0.5% of global oil consumption.

RheinEnergie green electricity seal

Power consumption

All of the electricity we purchase is green, and we are reducing the amount of power our machinery and equipment consume. We are acquiring injection moulding machines that are 40% more energy efficient and replacing old ones. We reduced power consumption by 11% in 2021 even as we increased production hours. 

Icon cycle

99% recycled

99% of our rejects in injection-moulding production (sprues, defective parts) are recycled and returned to the manufacturing process.

clean igus programme

Mechanical measures such as magnetic foils and guide plates prevent parts from falling out of the machines in the production process and becoming waste. We reduced our waste ratio (production waste + processed material) by 21% in 2021 thanks to these and other measures. 

Earth in front of green writing ISO 14001

Certified according to ISO 14001

In order to make our environmental policy transparent and comprehensible, we have been certified according to ISO standard 14001 since 2019, a recognised basis for environmental management systems. This helps us on our way towards a CO2-neutral factory.

Plastics in use


27 million tonnes of grease pollute the worldwide environment every year. Our polymers do not require lubrication.

Sustainability - durable products

Service life

Our polymers are optimised for wear. They do not corrode and do not get dirty from grease and dirt. They last longer and don't have to be replaced often. Thanks to our numerous tests in the test laboratory, we can calculate their service life exactly.

More sustainable - less weight


Plastic is lighter than steel and saves weight and therefore energy, which has to be applied for the movement. In an aeroplane, this amounts to roughly 4kg if iglidur plain bearings are used instead of metal-rolled bearings. This again positively impacts kerosene consumption.

Sustainability - less friction

Energy saving

Our polymers are tribologically optimised and have low friction. Together with the lower weight, this ensures that less drive energy has to be used to move a machine part in an application.

Sustainability - smart plastics

Predictive maintenance

Components are not replaced until they have reached the end of their product life cycle - this is the idea behind our smart plastics product range. Sensors indicate wear and parts are replaced when really necessary; resources are used carefully and rationally.

Sustainability - bearing exchange

Replaceable parts

Not having to replace the entire application when wear occurs was one of the leading ideas when we developed our exchange bearings for linear guides. The rail is not damaged and the bearing housing can be reused. This conserves resources - and simultaneously results in lower costs.

Sustainability - iglidur N54


With iglidur N54, we have developed a standard plain bearing that can be used universally and consists to 54% of renewable raw materials. The biopolymer bearing demonstrates that components can be sustainable, and motivates us in our future product development.

Graph conventional recycling

chainge Recycling Programme

We launched our "chainge" energy chain recycling programme in 2019. You can send us used energy chains (from igus or other manufacturers). You receive a voucher, and we separate components by type and use them ourselves or supply them to recycling partners. As of 12/2021, we have already received 25.97 tons of material.   

Graph Hydro Plastic Recycling Solution

HydroPRS recycling

We have invested five million euros in Mura Technologie, a company that uses a new technology, HydroPRS (Hydro Plastic Recycling Solution), to convert unsorted plastic waste to crude oil within 20 minutes. Conserves resources with pressure, temperature, and water. Construction of the first large-scale plant started in April 2021, and more and more companies are cooperating with Mura Technology.
