Most impactful to the calculation is whether the machine utilizes an electric, hydraulic or hybrid drive. Going further, the calculation is also impacted by whether one or two-circuit pump technology or hydraulic accumulators are used, as well as other options like servo-electric dosing or ejection. Arburg notes that any features that enable simultaneous, dynamic and fast movements and shorten cycle times have a positive effect on the carbon footprint during use. The same applies to the screw diameter and installed power, so that the greater the shot weight and the smaller the power consumption, the better.

Although these different material groups differ significantly in terms of the CO2 emissions generated during their production, Arburg says a weighted mean value can be determined along the lines of the distribution. This so-called emissions factor is around 1.83 [kg CO2 equivalent per kg product] for an Allrounder. The CO2 equivalent for the complete injection molding machine thus corresponds to the emissions factor multiplied by the press’ weight.

Additive technology creates air pockets in film during orientation, cutting down on the amount of resin needed while boosting opacity, mechanical properties and recyclability.

Arburg has utilized the ISO TS 1467:2018 standard, which determines the greenhouse gas emissions of a product, to help its customers calculate the product carbon footprint (PCF) of its injection molding machines.

In addition to sunglasses, the company is also manufacturing some custom orders such as hemp plastic keychains with required logos, as well as hemp chess sets, can openers, earrings, display boxes and guitar picks, among other items.

Arburg calculates that electricity related CO2 emissions during production generate an emissions factor of 0.366 [kg CO2 equivalent per kWh] for the standard German electricity mix in the year 2020. On that basis, the electricity requirement is 2900 kWh for the Allrounder 370 H, with a CO2 equivalent of around 1,160 kg, while for the Allrounder 570 H, the electricity requirement would be 7295 kWh with emissions around 2670 kg CO2.

When you drill down to the level of an individual screw, the complete parts list of an injection molding machine could consist of 11,000 indivdual items. To help it better manage that figure, Arburg categorizes all its raw materials into eight distinct materials groups. On this basis, an Allrounder consists of more than 55% plastic-coated cast iron, and another 35% of steel and sheet metal, whether they’re hot-treated, painted, plastic-coated or untreated. Plastic components, drives and electronic components account for only about 7% of the total weight.

Mold maintenance is critical, and with this collection of content we’ve bundled some of the very best advice we’ve published on repairing, maintaining, evaluating and even hanging molds on injection molding machines.

If the raw material and electricity-related emissions are added, the total CO2 equivalent for a “cradle to gate” analysis is 6530 kg for the Allrounder 370 H and 16,430 kg for the Allrounder 570 H. So what does that actually mean? By comparison, Arburg says each person in Germany generates an average carbon footprint of around 12,000 kg/yr, depending on personal consumption, mobility, housing and nutrition.

Nevertheless, the lack of hemp processing facilities — only two in the state — has affected the growth of the industry. And that’s one of the reasons the purpose of hemp cultivation has shifted from CBD to fibers that can be utilized in construction materials and clothing. Hemp has also seen interest in being used not only as animal and pet feed, but also for making protein-rich, plant-based hamburgers.

However, Arburg notes that two aspects of how and where it makes its machines change the calculation. Vertically integrated, Arburg manufactures around 60% of its Allrounder components itself, with this production occurring exclusively at its central location in Lossburg, Germany. That facility utilizes carbon-neutral renewable energies such as solar, wind and geothermal energy, as well as combined heat and power. Beyond that, since 2016, electricity purchased regionally has come entirely from sustainabile sources. This means that the emissions factor for Arburg’s electricity mix is actually only 0.17 instead of 0.366—53% lower than the German average.

Reducing plastic production should be one of the goals of all of us who inhabit the Earth. Two brothers from Nebraska, Andrew Bader and Steve Bader, are doing their part in saving the planet from plastic waste, which takes from 20 to 500 years to decompose.

Sustainability continues to dominate new additives technology, but upping performance is also evident. Most of the new additives have been targeted to commodity resins and particularly polyolefins.

In the first step, Arburg looks at the “cradle to gate” carbon footprint of its machines—that is the amount of carbon emitted in the manufacture of the press. This extends through raw material extraction and the manufacturing phase. All told, this portion of the machine’s existence only accounts for 5% of its CO2 emissions. On a cradle-to-grave basis, which weighs a machine’s entire life, most of the PCF is generated during the use phase at the customer’s factory. The remaining remnant is associated with emissions made during the machine’s distribution and disposal.

Implementing a production monitoring system as the foundation of a ‘smart factory’ is about integrating people with new technology as much as it is about integrating machines and computers. Here are tips from a company that has gone through the process.

In Nebraska, the home state where brothers run their company, there are currently 62 licensed hemp growers, up from the first 10 licensed in 2019. In 2021, 886 acres gained permission for cultivating hemp outdoors and some 266,600-square-feet in greenhouses.

As for the Bader brothers, they are planning to rent a facility and expand production. They are also looking for investors to help advance the molds they use to fashion their sunglasses.

Mixed in among thought leaders from leading suppliers to injection molders and mold makers at the 2023 Molding and MoldMaking conferences will be molders and toolmakers themselves.

Remembering that fully 95% of an injection molding machine’s PCF is attributed to its operation, Arburg says a key parameter to assess that is the specific energy requirement [kWh per kg], which is calculated from power consumption per material throughput. As a rule of thumb, the shorter the cycle time and higher the shot weight, the smaller the specific energy requirement and better the CO2 equivalent.

Successfully starting or restarting an injection molding machine is less about ticking boxes on a rote checklist and more about individually assessing each processing scenario and its unique variables.

After successfully introducing a combined conference for moldmakers and injection molders in 2022, Plastics Technology and MoldMaking Technology are once again joining forces for a tooling/molding two-for-one.

Using that figure, the electricity-related CO2 equivalent for the Allrounder 370 H is actually only 490 kg versus 1160 kg, while for the Allrounder 570 the emissions amount to 1240 instead of 2670 kg CO2.

As the European Union’s Green Deal takes effect and companies strive toward climate neutral production by 2050, knowing the product carbon footpring (PCF) of the entire supply chain will become increasingly important for European businesses. Arburg notes that in Germany the laws go even further, enforcing a 65% reduction in CO2 emissions by 2030 with carbon neutrality by 2045.
