Multi-chamber balers are designed for businesses that generate more than one waste stream, such as cardboard and plastic film, and want to keep materials separate without having to buy two machines. With multiple chambers side by side, they offer flexibility, save space, and streamline segregation.
We compared the PHS Wastekit 9020 Multi-Chamber Baler with the Compact & Bale-supplied MK1100 Twin baler to see which offers the best performance and value.
Build Quality and Design
The 9020 is a modular baler designed with two (or more, as available) chambers. This allows businesses to expand capacity over time by adding more chambers if waste volumes increase. Its compact design makes it suitable for retailers, hospitality venues, and offices.
The MK1100 Twin also has two chambers, but with a slightly larger footprint and reinforced steel construction. It uses one press plate that can be moved between chambers, making it ideal for businesses with steady volumes of cardboard and plastic packaging.
Verdict: Both are durable, but 9020S offers modular flexibility, while MK1100 Twin is built for higher daily throughput.
Performance and Capacity
The 9020 produces bales weighing around 250 kg, depending on the material. This is sufficient for most recyclers but may require more bales overall compared to heavier machines.
The MK1100 Twin also produces bales of up to 250 kg. This reduces storage space requirements and collection frequency.
Verdict: Both balers are around equal on grounds of capacity.
Usability and Features
The 9020 is simple to operate, with clear controls and a safe bale ejection system. Its big selling point is flexibility: operators can segregate waste streams and, if needed, expand the unit with additional chambers.
The MK1100 Twin provides the same segregation functionality but focuses on productivity. With slightly larger chambers and stronger compaction, it handles bulkier materials more easily. Compact & Bale also provide staff training and aftercare as part of their package.
Verdict: Both are easy to use; MK1100 Twin is more efficient for busier sites.
Energy Efficiency and Running Costs
The 9020 runs on a standard power supply and is efficient for its class, with relatively low operating costs.
The MK1100 Twin also runs efficiently, but Compact & Bale add value by collecting bales and paying rebates for recyclables. This helps customers recover costs and, in many cases, generate income from their waste.
Verdict: Equal on energy efficiency, but MK1100 Twin delivers stronger lifetime ROI with rebate payments.

Wrapping Up
The PHS Wastekit 9020 is a versatile, modular baler that works well for businesses wanting to bale multiple waste streams and keep options open for expansion.
The Compact & Bale MK1100 Twin, however, offers slightly heavier bales, stronger construction, and the added benefit of Compact & Bale’s rebate and collection service. This makes it more efficient and more profitable over its lifetime.
For flexibility, the 9020 is a good option. But for businesses focused on efficiency, cost savings, and long-term ROI, the MK1100 Twin is the better option.
