Automation behind a leap in sustainable bottle output

Our Efficient Motion Control technology powers Frugalpac’s new generation of high-performance Frugal Bottle Assembly Machines (FBAM-2), boosting output by more than fivefold.

Who says a bottle has to be made of glass?

Frugalpac, a King’s Award-winning cleantech company based in Suffolk, UK, is decarbonizing the packaging industry with bottles made primarily from recycled paperboard and produced close to filling lines. Whether for wine, spirits or edible oils, these lightweight, fully recyclable containers offer clear sustainability advantages over glass: They use at least four times less water in production, weigh five times less in transport and have up to an 84% lower carbon footprint. The bottles are fully recyclable too: not only the outer paper layer itself but also the mono-material polyethylene-based food-grade pouch within it, which can be easily separated.

This more sustainable packaging solution has caught on – so much so that Frugalpac has developed a new generation of machines to produce its Frugal Bottles: Frugal Bottle Assembly Machine 2 or FBAM 2. It increases annual output per line from around 2.5 million to over 14 million. Behind this leap are multiple innovations – from process and machine design improvements to a fully integrated automation architecture.

Lightweight

70 g per Frugal Bottle reduces material use and cuts the carbon footprint to 92 g CO2e versus 558 g CO2e for glass.

100% recycled

Glass bottles typically contain around 35% recycled content; Frugalpac bottles are made entirely from recycled paperboard.

Proven impact

Over 4 million Frugal Bottles produced has saved over 1,392 metric tons of CO2, equal to 5.6 million kilometers driven by a gas-powered car.

A collaborative approach

The journey to FBAM 2 started with a strategic partnership in which we came together with Frugalpac and Underwoods, a certified Siemens Industry Distribution Partner. Over a period of ten months, the team worked on redesigning the machine control system to improve scalability, reliability and efficiency, while ensuring consistent processing of 100% recycled material. On the commercial side, Frugalpac is collaborating with Siemens Financial Services – our B2B financing arm – to offer tailored payment solutions to their customers.

"Through strong collaboration with Frugalpac and Underwoods, we transformed an innovative concept into a scalable, high-performance industrial solution that delivers beyond the output levels of conventional glass bottle manufacturing alongside significant decarbonization of the beverage industry," comments Olly Gibbs, OEM Account Manager at Siemens.

The solution consists of a complete controls package built around our Efficient Motion Control technology, including a Simatic S7‑1500 CPU for advanced motion control and Sinamics S120 servo drive systems with more than 20 coordinated axis movements. The result is precise coordination of the machine’s many moving parts, enabling higher speeds and consistent performance. Simatic HMI Unified Comfort Panels provide intuitive operator interaction and full transparency about machine status.

All components are fully integrated within the engineering platform TIA Portal, which brings software and hardware configuration – across PLCs, drives, HMIs, communication networks and safety – into a single project. This integration is supported by pre‑verified function modules, which accelerates development through reduced commissioning time and engineering effort. That means faster rollout and scaling. In addition, the network-based control architecture significantly reduces wiring requirements, allowing Frugalpac to achieve savings of up to 65% in wiring costs while enhancing system reliability and flexibility. So that Frugalpac’s people can get accustomed to working with the technology installed in FBAM 2 – such as TIA Portal and cybersecurity solutions – Sitrain courses are also part of the project.

Set for growth

All of this technology has made FBAM 2 significantly faster than its predecessor – it takes just three seconds to produce a single bottle. These higher speeds mean up to 30% lower overall bottle costs and faster returns. At the same time, the machine was designed with scale in mind to support the vision of a global fleet. Built-in cybersecurity standards ensure secure connectivity for remote installation support and lifecycle management, while connected data enables continuous monitoring and energy optimization. Furthermore, the experience gained with the FBAM 2 fleet will serve as the foundation for future machine generations.

The FBAM‑2 gives the industry a practical way to move faster – cutting carbon, reducing costs and producing bottles closer to where drinks are made and sold.

Beyond the Bottle: New packaging horizons

With its Frugal Bottle – fully recyclable, lightweight and made close to bottling lines – Frugalpac is advancing its goal of decarbonizing the packaging industry. Aside from bottles, Frugalpac is currently looking at extending its portfolio to include the Frugal Carton for everything from juice and milk to cereal and the Frugal Pot for holding paint. In all its activities, the company is committed to a high level of recyclability and to giving its customers greater control over the outside of their packaging for branding, advertising and other custom design elements.

About Frugalpac

The biggest innovation for wine and spirits since the launch of the glass bottle

The people at Frugalpac are motivated by a passion to reduce the impact of carbon on the planet through packaging that uses recycled paper that’s easy to recycle again. The company operates its own engineering innovation center in Ipswich, UK.
