For businesses producing medium-to-high volumes of cardboard and plastic waste, mid-to-large vertical balers are the ideal step between small balers and full mill-size models. They produce dense bales in the 300 kg range, cutting down on waste collections while still being manageable for most handling equipment.
We compared the KK 30 LH with the Compact & Bale-supplied Strautmann BP28 to see which offers the best performance and long-term value.


Build Quality and Design
The KK 30 LH is a low-height vertical baler designed for sites where ceiling space is restricted. Despite its compact height, it delivers strong compaction and is built for consistent use in retail, hospitality, and medium-sized warehouses.
The BP28 is a traditional full-height vertical baler, built with reinforced steel and a heavy-duty press. It has a slightly larger footprint but prioritises maximum bale density in its class.
Verdict: KK 30 LH is ideal for sites with height restrictions; BP28 is better suited to sites prioritising bale density.
Performance and Capacity
The KK 30 LH produces bales of up to 300 kg, depending on material. This reduces waste volumes significantly and keeps storage areas tidy, though more bales may be required overall compared to larger models.
The BP28 produces heavier bales of 320–350 kg, meaning fewer bales per tonne of waste and stronger rebate potential.
Verdict: Both are efficient, but BP28 offers heavier bales for greater savings and rebates.
Usability and Features
The KK 30 LH is easy to load and operate, with a lower overall height that makes it more practical for smaller spaces. Safe bale ejection and simple controls keep training requirements minimal.
The BP28 also offers straightforward front-loading and safe bale ejection, but with a larger chamber and aperture that make it more suitable for bulkier materials and higher daily throughput. Compact & Bale back this up with full operator training and integration options.
Verdict: Both are user-friendly; BP28 is more versatile for larger, bulkier loads.
Energy Efficiency and Running Costs
The KK 30 LH is economical to run on a 3-phase supply, keeping energy costs in line with its size. Servicing is arranged through KK Balers.
The BP28 also uses a 3-phase supply and has similar energy demands. Where it differs is Compact & Bale’s collection and rebate model: not only do they supply and service the machine, but they also collect recyclables and pay rebates, turning waste into a revenue stream.
Verdict: Equal on efficiency, but BP28 lowers lifetime costs through rebates.
Specification Comparison: KK 30 LH vs BP28
| Feature | KK 30 LH | Compact & Bale BP28 |
|---|---|---|
| Type | Mid-to-large vertical baler (low height) | Mid-to-large vertical baler |
| Press Force | ~30 tonnes | ~28 tonnes |
| Bale Weight | Up to 300 kg | 320–350 kg |
| Loading Aperture | Standard front-loading | Larger front-loading aperture |
| Cycle Time | 45 seconds | 19 seconds |
| Power Requirement | 3-phase | 3-phase |
| Bale Ejection | Automatic | Automatic |
| Machine Height | Lower profile (for restricted sites) | Full-height (standard installation) |
| Suitable Waste | Cardboard, plastics, packaging | Cardboard, plastics, packaging |
| Aftercare and Service | KK Balers service | C&B service + collection and rebates |
Why Bale Weight Matters
The heavier the bale, the fewer are needed to process the same amount of waste. This not only saves labour but also reduces transport costs and boosts rebate income. While the KK 30 LH’s 300 kg bales are effective, the BP28’s 320–350 kg bales provide more efficiency and revenue potential over time.
Wrapping Up
The KK 30 LH is a reliable mid-size baler that stands out for its low-height design, making it a great choice for businesses with ceiling restrictions or space limitations.
The Compact & Bale BP28 produces consistently heavier bales, making it the stronger option for businesses looking to maximise efficiency and rebate returns. Combined with Compact & Bale’s collection and rebate service, the BP28 becomes a complete waste management solution.
For restricted spaces, the KK 30 LH is a smart option. But for most businesses focused on ROI, efficiency, and support, the BP28 offers the most benefits.
