40 PROCESSING AND PACKAGING The circular economy in packaging technology: Sustainability needs collaboration The requirements placed on food packaging are immense. It needs to provide protection while simultaneously conveying the brand image, be tightly sealed yet easy to open, and create a reliable barrier while also being breathable when required. During the production process, it must also enable high-speed food packaging while, of course, remaining cost efficient. Decades of research and development have gone into tackling these diverse tasks. In recent years, the demand for sustainability has become huge. New packaging solutions need to be developed as soon as possible. They need to meet the same requirements as conventional packaging without burdening the environment or the purse. Syntegon Technology has set itself this Herculean task, which it is addressing in cooperation with all supply chain participants. By TORSTEN SAUER On the road to sustainable packaging solutions, the “circular economy” is pointing the way. This approach seeks to close energy and material cycles through the efficient use of resources, recycling and waste reduction. The aim is to achieve a sustainable improvement in environmental and climate protection. With this goal in mind, the European Union (EU) passed the Circular Economy Act in 2012 1 . The core of this legislation is a fivelevel hierarchy of waste, which helps to consistently orient the circular economy towards waste avoidance and recycling. It defined a sequence of waste avoidance, reuse, recycling and waste recovery – including energy recovery – and finally waste disposal. In each case, the most environmentally friendly option has priority. Syntegon Technology has set itself the goal of making a contribution to sustainability through its packaging solutions. This calls for collaboration with customers as well as packaging material manufacturers and suppliers, which Syntegon Technology sees as part of the solution. In concrete terms, the aim is to make both the packaging itself and the packaging process more sustainable. This includes, in particular, the development of machines that can process new, more environmentally friendly packaging materials. Syntegon Technology has developed a number of solutions with customers that target the first three stages of the waste hierarchy – waste avoidance, preparation for recovery, and recycling.

PROCESSING AND PACKAGING 41 The new blank feeding motion of the Elematic 2001 case packer can accommodate blanks that have been bent by moisture and changing temperatures. As a result, fewer blanks need to be thrown away, which contributes to more sustainable production processes STAGE 1 – AVOIDANCE: NO PRODUCT AND MATERIAL WASTE Packaging requirements are not necessarily at odds with sustainability. Primary and transport packaging offer product protection, and therefore contribute to sustainability by preventing food spoilage or waste during transport. An optimised packaging process also helps to prevent product waste. During necessary downtime for cleaning or format changes, batches can spoil and have to be disposed of. Minimising downtimes thanks to easier cleaning and faster format changeovers helps to reduce waste. In addition, more efficient production processes also mean resources, such as energy and water, are used more efficiently. Optimising machines can also help to reduce the amount of packaging material. The continuous development of sealing technologies is already doing its bit. Thanks to technological advances, thinner films can now be used while packs can be sealed more tightly around the product. This helps to reduce the amount of material used. Syntegon Technology has also developed cartoners and case packers that are more material-efficient thanks to higher tolerances. These include systems that can process slightly bent cardboard blanks or those made from recycled material. This wider tolerance range means that blanks, that would previously have been discarded as rejects, are now being processed by the machine. Efficiently designed secondary packaging and outer packaging also helps to minimise transport costs. According to Olivier Cottard, head of industries business units at DS Smith Packaging, shrinking standard secondary packaging by 5mm reduces shipping requirements by 20 truckloads per year. This results in carbon emissions savings of 100 metric tonnes as well as significant cost savings. Put differently, the carbon emissions savings are equivalent to the amount of carbon absorbed by 2,500 conifer seedlings in 10 years 2 . Waste prevention also involves replacing environmentally harmful packaging materials with more environmentally friendly options such as using paper instead of plastic. Paper or cardboard already account for around 65% of all packaging 3 , but the application possibilities for paper in primary packaging are far from exhausted. Syntegon Technology is currently working on making conventional plastic packaging solutions usable with paper In collaboration with the paper manufacturer BillerudKorsnäs, Syntegon Technology has developed a process for securely packaging and sealing dry foods such as sugar, pasta, or cereals in mono-material paper using vertical flow wrappers FOOD & BEVERAGE ASIA JUNE / JULY <strong>2021</strong>
