Sweden is home to two world-leading manufacturers in this field: Presona and Orwak. While both are Swedish companies with strong reputations, they focus on different market segments and employ distinct technological approaches.

Presona: Heavy-Duty Equipment for Large-Scale Industrial Recycling

Presona is the preferred choice for large-scale industrial recycling operations. The company is renowned for its robust, fully automatic horizontal balers designed for continuous, 24/7 operation.

Core Technology: The Pre-Press System
The key differentiator for Presona is its patented pre-press technology. Unlike traditional shear balers that cut material before compression, the pre-press system compresses material directly into the main chamber. This innovation offers two major advantages.

First, it delivers exceptional energy efficiency. By eliminating the need for high-powered shearing, Presona balers are up to 60 percent more energy-efficient than conventional models, significantly reducing long-term operating costs.

Second, it reduces wear and tear. With fewer moving parts subject to high friction—such as shear blades—the machine experiences less wear, leading to a longer lifespan and lower maintenance requirements.

Custom-Built Solutions
Presona does not produce standardized off-the-shelf balers. Instead, the company works closely with each client to tailor the system to their specific needs. A wide range of options is available, including conveyor belts, material distributors, automatic wire break monitors, and even PET bottle perforators for achieving higher bale density.

Typical Applications
Presona balers are ideal for large recycling centers, material recovery facilities, and major retailers. For example, Salling Group, the owner of Netto supermarkets, uses a Presona LP 85 VH1 to bale materials collected from over 250 stores, effectively turning what was once a waste management cost into a profit center.

Orwak: Compact and Versatile On-Site Baling Solutions

Orwak, now part of the TOMRA Group, is a leader in compact and versatile baling equipment. The company’s machines are designed for businesses that need to manage recyclables on-site, particularly in spaces where a large industrial baler would not fit.

Core Strengths: Vertical Balers and Versatility
Orwak is famous for its vertical balers, which occupy minimal floor space. A prime example is the Orwak 5040, which was originally developed for RePlanet recycling centers located near shopping malls and supermarkets. This model is notable for being one of the few compact vertical balers capable of compacting PET bottles with their caps on, making it highly efficient for handling beverage containers like aluminum cans.

High-Performance Horizontal Models
For larger operations, Orwak also offers fully automatic horizontal balers, such as the 1000 ATH. These machines are designed to produce mill-size bales that can be sold directly to downstream processing industries. They are ideal for large-scale waste handling at shopping centers, distribution centers, and recycling plants.

Typical Applications
A recent example is Carlsberg Croatia, which installed an Orwak MULTI 5070-HDC high-density baler in early 2026. This machine is specifically engineered for aluminum cans and PET bottles collected through deposit return systems. Its multi-chamber design allows for efficient material separation at the source, reducing transportation frequency and the company’s carbon footprint.

A Note on Swedish Innovation in Aluminum Packaging

Beyond world-class recycling machinery, Swedish innovation is also shaping the future of the aluminum can itself. A Swedish company called Meadow has developed the MEADOW KAPSUL™ technology. This technology modifies the can’s opening mechanism to create a pre-filled cartridge for a reusable dispenser. The system aims to reduce raw material consumption while maintaining full recyclability. It has received significant investment from the global can giant Ball Corporation, representing a forward-looking trend in Swedish aluminum packaging that could influence the types of cans entering the recycling stream in the future.

I hope this gives you a clear picture of the Swedish aluminum can baler landscape. If you can share your specific processing volume requirements—such as tons per hour—or your intended application, I would be happy to provide more targeted recommendations.
