Multi-Chamber Waste Balers
Multi-chamber waste balers
Built for segregated waste streams
If your site generates more than one type of recyclable waste, a multi-chamber baler gives you the efficiency of multiple machines in a single compact unit. Instead of handling different materials separately – or investing in additional standalone balers – each chamber can be loaded and compacted independently, keeping waste streams clean, compliant, and ready for a streamlined collection. Our range – comprising the RWM 40 PET Multi, RWM 75 Multi, and RWM 200 Multi – spans compact entry-level solutions right through to higher-capacity configurations, with two chambers as standard and the option to add more. Whether you're a retailer separating cardboard from plastic film, a manufacturer managing multiple waste streams across the production floor, or a logistics operation handling different grades of plastic packaging, there's a machine built for every setup. Talk to us about your requirements, and we'll help you find the right fit.
Waste balers
What is a multi-chamber baler?
A multi-chamber waste baler is a vertical baling press with two or more independently operable chambers, each compressing a different recyclable material into neat, tied bales. A single set of electric and hydraulic components powers the entire unit, so businesses handling mixed streams – such as cardboard and plastic film – can bale each material separately without the cost, footprint, or maintenance overhead of running two standalone machines. Think of it as a two-in-one solution.
Here’s how a multi-chamber waste baler works:
- Each chamber has its own loading aperture, and materials are loaded into the correct chamber as waste is generated
- A shared hydraulic ram compresses each chamber in turn, producing dense, uniform bales
- Once the required bale size has been achieved, the operator ties the bale with wire or tape
- The finished bale is ejected and can be stacked, stored, or collected – separated by material type and ready for recycling
Chamber configuration, pressing force, and bale output vary by model. If you’re unsure what your business needs, our team is happy to help you identify the best specification.
By input
What materials does it bale?
Most Riverside balers are used to compact cardboard, paper, plastic film, and other dry recyclables. However, some of our larger and more powerful models are also suitable for denser or more specialist materials, including rigid plastics like PET and HDPE, light metals like aluminium cans, and textiles from production or returns processing. The right machine depends not only on the material itself, but also on the volume generated, available space, and how you need the finished bale to be handled. If you're unsure about suitability, get in touch and we’ll be happy to advise.

Bringing benefits in abundance
01
Get two machines in one
A multi-chamber baler delivers the output of multiple units from a single set of components, reducing the upfront investment while lowering ongoing energy and maintenance costs.
02
Segregate at source
Each chamber keeps a different material separate from the moment it’s loaded – protecting bale quality, satisfying processor requirements, and eliminating the time and cost of sorting later.
03
Reclaim floor space
One machine replaces the footprint of two or more separate balers and keeps loose waste contained – clearing walkways, minimising fire risks, and creating a safer working environment.
04
Recover more value
Separating and baling materials at source helps maintain cleaner recycling streams. This reduces contamination, improves recycling efficiency, and helps maximise material recovery.
05
Strengthen sustainability
Clean and consistent segregation supports environmental reporting, helps meet waste duty of care requirements, and demonstrates a visible commitment to responsible recycling.
06
Operate with ease
Top-loaded apertures and user-friendly controls mean our multi-chamber balers slot into busy workflows with minimal training, with a service and maintenance team on hand when needed.

Meet the RWM 150
If your operation only generates one recyclable stream, you likely don’t need a multi-chamber waste baler at all. The RWM 150 is a mid-range machine designed to handle high volumes of cardboard, paper, and plastic film in a single chamber, producing bales of up to 150kg with a compact footprint to match. It's a reliable, cost-effective solution for businesses generating significant volumes of a single recyclable material. It can also be an effective choice for larger facilities, where individual balers are positioned close to the source of waste, reducing internal handling and improving operational efficiency.

"SWM are committed to safety, which is one of the key factors in sustaining relationships with suppliers and contractors – that’s why Riverside Waste Machinery Ltd has been servicing our internal balers successfully for a number of years. We recently needed to purchase a tipping skip and – despite not being advertised on their website at that time – Riverside happily provided a quote, which we accepted, and delivery was made promptly after."
