Polykemi have conducted a scientific study in 2020 and used the results to develop a simulation tool.
“The simulation tool enables us calculate the cradle-to-gate carbon footprint of all our materials. The results demonstrates that the choice of material has is significant in the fight against climate change” explains Henrik Palokangas, Sustainability Specialist at Polykemi.
“This enables our customers to assess the environmental footprint of the components they produce.”
“It’s easy to select materials out of force of habit, even though there may be significantly better alternatives available that would reduce costs, save time and lower the carbon footprint. We can demonstrate the difference material choices make and help select an optimal alternative”.
The right material for the right purpose – part of the solution
For any finished product on the shelf, between 60 and 80 percent of the carbon footprint originates from the raw materials it is produced from. That is why manufacturers have a responsibility to choose the best materials for their product.
In many cases, the carbon footprint can be reduced significantly by selecting plastic instead of, for instance, metal. For example PP is 10 times smarter material-wise because of its lower carbon footprint and its lower weight.
According to Polykemi’s scientific study, changing from the virgin material PA6 GF15 to PP GF15, which is technically possible in many applications, will reduce the carbon footprint by 6.9 kg of CO2e for every kg of material, i.e. 75 percent.
If a recycled PP is an option, the carbon footprint can be reduced by yet another 75 percent.
“Even virgin materials can provide significant climate savings. In addition, there is a lower density, which means that we can produce 15-20% more details on each kilo of material. This gives both increased profitability and enhanced climate performance,” says Mr. Palokangas.
“There is more to being material-smart than just using recycled materials.”
