If your business generates cardboard waste, and most do, a cardboard baler machine is one of the most straightforward ways to cut costs, gain back storage space, and turn a disposal problem into a potential revenue stream. But with several machine types on the market, choosing the wrong one is an avoidable and expensive mistake. Here’s what you need to know.
What is a Cardboard Baler Machine?
A cardboard baler uses a hydraulic ram to compress loose cardboard into dense, tightly-bound bales. Instead of overfilling bins or waiting for frequent collections, your cardboard is compacted on-site and stored neatly until it’s collected or sold. Mardon’s RamPack range can reduce disposal costs by up to 90%, and the larger mill-size models produce bales heavy enough to generate rebate income from waste collectors.
Simpler Recycling Legislation
Since 31 March 2025, Simpler Recycling legislation has required all businesses and non-domestic properties in England with 10 or more full-time employees to separate their waste into dry recyclables, food waste, and general waste. Paper and cardboard must be separated from other dry recyclables unless your waste collector gathers them together. For businesses that were previously throwing cardboard into mixed skips, this is a significant operational change, and a baler is one of the most practical ways to manage it.
The Three Types of Cardboard Baler, and Which One Suits Your Business
Vertical Balers
Vertical balers are the entry point. Mardon’s RamPack vertical range is designed for sites with small to medium volumes of recyclable waste, with a small footprint that suits locations where space is tight. Models range from 40kg to 650kg bale weights, so there’s a lot of variation within the category.
The smaller mini-range suits offices, independent retailers, and trade counters; the larger mill-size models are suited to businesses generating consistent volumes who want to maximise rebate income.
Material is fed in from the top and compressed downward, with the operator manually tying the bale.
Semi-Automatic Horizontal Baler
Semi-automatic horizontal balers sit in the middle. Mardon’s semi-auto RamPack range is programmed to bale automatically; the operator is notified when the bale is ready to be tied off and ejected, reducing the manual element significantly. With a pressing force of 36–80 tonnes and multiple loading options, these suit medium to large businesses producing steady volumes of cardboard, paper, soft plastics, or aluminium cans.
Retailers, builders’ merchants, and distribution operations are a natural fit here.
Fully Automatic Channel and Twin Ram Balers
These are for high-volume sites that need continuous throughput with minimal operator involvement. When combined with a conveyor system, Mardon’s fully automatic channel baler can run around the clock. The twin ram range steps it up further, with a pressing force of up to 180 tonnes and throughput of up to 18 tonnes per hour. It handles harder-to-bale rigid materials as well as cardboard and paper.
These are industrial installations suited to large distribution centres, manufacturing plants, and supermarket chains.

Matching Baler to Business: The Three Variables
Volume
Measure your cardboard output accurately over a couple of weeks before specifying a machine. Estimates tend to be too low.
Space
Vertical balers are compact by design. Horizontal and channel balers need significantly more floor area, plus clearance for loading and bale removal.
Labour
If staff time is limited, the semi-automatic and fully automatic options reduce operator involvement considerably. The machine does the compressing; you just deal with the finished bale.
Finance and Purchasing Options
Mardon offers finance and purchasing options alongside outright sale, making it easier to spread the cost of a machine against the savings it generates. Given that a baler can reduce disposal costs by up to 90% and the larger models generate rebate income, the payback case tends to be strong, but the right calculation depends on your actual volumes and current waste contractor costs. Mardon offers free site surveys to work through this with you.
If you’re unsure where to start, the free site survey is the sensible first step. You can reach the team on 0800 587 3028 or at sales@mardongroup.co.uk.
Frequently Asked Questions
What is a cardboard baler, and how does it work?
A cardboard baler uses a hydraulic ram to compress loose cardboard into dense, tightly-bound bales. These bales are easier to store, cheaper to collect, and in larger volumes can be sold to waste collectors for rebate income.
What size baler do I need?
It depends on your weekly cardboard volume, available floor space, and how much staff time you can dedicate to operating it. Vertical balers suit smaller sites with moderate volumes; horizontal and channel balers are better suited to medium and high-volume operations. A free site survey will give you a precise recommendation.
Do I legally need to separate my cardboard waste?
In England, yes. Since 31 March 2025, Simpler Recycling legislation requires all businesses with 10 or more full-time employees to separate dry recyclables, including cardboard, from general waste. A baler is one of the most practical ways to manage this on-site.
