Aurora Organic Dairy installed an Aseptic Combi Predis from Sidel in their second milk plant, a greenfield project in Columbia, Missouri. FDA-approved and part of a complete line, which also features Tetra Pak Processing Systems technology. This bottling solution helped the key player in the US organic dairy market expand its organic milk offerings from ultra-pasteurized cartons and HDPE gallon jugs to PET. This choice marks the start of a new journey for Aurora – bottling its UHT milk in PET, ultimately enabling an attractive and premium packaging that reaches consumers in new channels.

Founded in 1976 and headquartered in Colorado, Aurora is a pioneer in the field of sustainable and organic milk production. The company has come a long way from converting its first farm in Colorado to exclusive organic production in 2003 and building its on-farm milk plant in Platteville, Colorado, in 2004. Now, Aurora Organic Dairy is the leading producer and processor of store-brand organic milk and butter for US retailers. The company’s unique selling point is their philosophy that starts from crop growing to distribution of their award-winning dairy products – the company’s vertically integrated supply chain offers unparalleled traceability and affordable organic dairy with excellent quality. As they continuously seek to collaborate with forward-thinking companies that share their values around innovation, they chose Sidel’s Aseptic Combi Predis at their new plant in Columbia, Missouri. This solution allows for an expanded product line, namely a variety of products in PET bottles.

Breaking with traditions to sustain core values in a competitive market

As the leading store-brand organic dairy producer and processor in the US, Aurora continues to challenge themselves in line with their goal – to bring organic milk to mainstream America with the highest quality and freshness, more affordable pricing, and improved availability for consumers.

According to Aurora Organic Dairy’s Chief Customer Officer, Jason Lee, the beverage category has been quickly changing, which makes it challenging to compete in the traditional Liquid Dairy Products (LDP) market without adapting to change. He explains, “We’re seeing growth opportunities and customer interest in aseptically bottled milk and milk-based products in PET. These observations have opened the door for unique private brand products to stand out on the shelf – setting them apart from national brands and the more traditional packaging for liquid dairy. We continue to work toward our mission by bringing the nutritional benefits of organic dairy products to more people in more places with a commitment to integrity in everything we do. This is why we relentlessly seek innovations to achieve product differentiation.”

After years of processing ultra-pasteurized milk in gallon jugs and half-gallon cartons, Aurora started to bottle low-acid, shelf-stable organic milk in PET in 2019 by choosing Sidel’s Aseptic Combi Predis. By doing so, Aurora benefits from increased marketing opportunities while leveraging a cost-effective and flexible production process. PET packaging allows brand differentiation due to the virtually endless design freedom it offers while ensuring strong brand recognition across a complete bottle family from large to on-the-go formats. These properties are highly valued by Aurora, which is now producing its organic milk bottled in PET in 8oz, 12oz, 16oz, and 32oz squared containers, reminiscent of the classic glass milk bottles used for home delivery in the past.

An FDA-approved aseptic PET solution for Aurora

Aurora implemented Sidel’s Aseptic Combi Predis because of its certified proficiency. On top of its more than 180 references worldwide, the solution was the world’s first aseptic PET filling equipment with dry preform sterilization to get approved by the FDA three years ago. Thus, Aurora’s extremely high standards are preserved by the barrier properties offered by PET – enabling the highest food safety requirements – and the 100% sterile processing and packaging provided by the line. Sidel’s reputation in aseptic packaging (more than 40 years both in PET and in aseptic applications) was also a key purchasing factor for Aurora, backed up by their first-hand experience of Sidel’s center of expertise for filling plus some customer visits in the US as well as in Europe to observe the Combi Predis in action.

Big change made easy

Sidel’s Aseptic Combi Predis offers the simplest and fastest dry preform decontamination on the market, the lowest Total Cost of Ownership (TCO), and an optimized environmental footprint. No water is used in this process, and the use of chemicals is radically reduced while maintaining a high output, offering good ease of operations, and ensuring a very flexible production. The latter aspect was a critical success factor in this project, considering Aurora’s need for producing multiple SKUs and delivering on store brands’ expectations.

Teams from Sidel and Aurora have completed the ramp-up and the commercial validation of the aseptic PET complete line, successfully filling the various bottle formats, now available on the market.

“Our innovation team has been working very closely with the Sidel packaging team to develop new container designs quickly. Sidel has been a great partner throughout this process, and we are extremely excited about the future capabilities this line provides our customers and us,” Lee concludes.

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.
