We are aware that the processing of plastics and the placement of plastic products on the market has consequences for the environment. We strive to keep these effects to a minimum, while maintaining an adequate level of economic efficiency. For this task, a cross-departmental team at igus is working on ways of identifying these effects and finding solutions to reduce them.
We consider the protection of the environment and climate to be an important element of our activity and mission. The avoidance of harm to the environment and sparing use of the limited resources that are available are therefore permanent components of our corporate responsibility.
The central environmental aspects for use, are the levels of energy consumption in plastics production and the creation of plastic waste. With a recycling rate of 99% for our internal injection moulding waste, we have already taken an important step.
In addition, our team is working on ways to make recycling even more efficient, prevent contamination caused by igus products and reduce energy consumption in their production.
We all contribute towards protection of the environment by:
25/09/2020 | In order for our extruders, which are needed for the production of bar stock, to function properly, they need cooling. For this purpose cold water is passed through the machine. It heats up and there comes the crux of the matter - until now, clean water has been discharged directly back into the sewage system.
We now want to change this and are therefore building our own re-cooling plant. After passing through the machine, the water is then cooled down again in a cooling tower, stored and can be used again to cool the machine. We are already using it for our injection moulding machines, and now an additional re-cooling system will also reduce the extruders' water consumption by more than half.
23/09/2020 | When an injection moulding machine ejects new parts, it may happen that they end up on the floor next to instead of in the collection container. Although there is nothing wrong with these parts, they are then thrown away. The fact that a part from the machine does not end up in the collection container may sound like an exception at first, but it is not at all uncommon, and above all the quantity accumulates with the large number of machines used in production.
A significant amount of waste can therefore be saved if the machines and their conveyor belts are optimised. For example, by the use of lids over the collection containers. Other measures are the sealing of gaps with magnetic foil to close the transition from the discharge chute to the conveyor belt. Even if this sounds banal, the sum of the individual measures brings the effect and in this case unnecessary plastic waste can be reduced.
