Semi-automatic horizontal balers are the workhorses of high-volume recycling. They produce dense, transport-efficient bales quickly and consistently, saving labour and unlocking maximum rebates from recyclers.

We compared the KK 500 SA with the Compact & Bale CB58 to see which delivers the best efficiency, bale weight, and long-term value.

Build Quality and Design

The KK 500 SA is a heavy-duty baler with full chamber force for maximum compaction. It has a wide 2m × 1m loading aperture, making it well suited for bulky cardboard and high-volume plastics.

The CB58 is similarly robust, built from reinforced steel with hydraulic power optimised for dense compaction. It has a slightly smaller footprint but is designed for the same high-volume applications, with features for easy integration with conveyors or bin tippers.

Verdict: Both are rugged industrial machines; CB58 offers a more compact footprint with strong integration options.

Performance and Capacity

The KK 500 SA produces bales up to 650 kg, depending on material. This is heavier than the typical “mill-size” range, giving it an edge in compaction for very dense recyclables.

The CB58 consistently produces up to 550 kg mill-size bales, which fall squarely within the weight range most reprocessors prefer for rebate payments. While not as heavy as the KK, these bales are universally compliant and easier to handle.

Verdict: KK produces heavier bales, but CB58 hits the optimal rebate-ready weight more consistently.

Usability and Features

The KK 500 SA is simple to use, with push-button controls, manual wire tying, and safe bale ejection. Its reduced loading height makes it easier to feed bulky material.

The CB58 offers similar semi-automatic functionality, but Compact & Bale provide full operator training and servicing as standard. Options such as conveyor or bin tipper integration reduce labour time further.

Verdict: Both are straightforward to operate; CB58 is better supported with training and integration.

Energy Efficiency and Running Costs

The KK 500 SA runs on a three-phase power supply and is marketed as low maintenance. Servicing and parts are handled through KK Balers.

The CB58 also uses a three-phase supply with similar energy demand, but Compact & Bale’s model is different: they not only service the machine, they also collect the bales and pay rebates, offsetting lifetime running costs.

Verdict: Equal on energy, but CB58 offers stronger ROI through rebates.

Why Bale Weight Matters

Producing heavier bales reduces storage space and collection frequency. The KK 500 SA can produce extra-heavy bales up to 650 kg, which is valuable for dense plastics but can be harder to handle.

The CB58, by contrast, produces 500 kg mill-size bales, the industry standard for recyclers. This makes them easier to manage and guarantees maximum rebates without handling issues.

Wrapping Up

The KK 500 SA is a powerful semi-auto baler capable of producing extra-heavy bales of up to 650 kg. It’s ideal for sites dealing with dense plastics or wanting maximum compaction.

The Compact & Bale CB58 matches this with industrial-grade performance, producing consistently rebate-ready 500 kg bales, while adding Compact & Bale’s collection and rebate service for better lifetime value.

For sheer bale weight, the KK 500 SA has the edge. But for overall efficiency, rebate compliance, and complete service support, the CB58 is the Best Buy.
