A distribution centre is arguably the most consistent and predictable waste-generating operation in the commercial world. Every inbound pallet carries goods wrapped in stretch film and packaged in corrugated cases. Every goods receipt shift unwraps pallets and opens cases, generating the same two streams continuously: cardboard and plastic film. Every returns processing area adds further cardboard and packaging to the stream.
This predictability is an asset for waste management planning. Unlike a retailer where waste composition varies with product mix and seasonal trading, or a manufacturer where process waste is specific to the production type, a distribution centre generates the same two primary waste streams in volumes that scale directly and predictably with throughput. If you know your daily pallet intake, you can estimate your daily cardboard and film generation with reasonable accuracy. If you can estimate the volume, you can specify the right baling equipment with confidence.
The financial opportunity is correspondingly clear. Cardboard from a distribution centre is among the cleanest and most commercially valuable cardboard bale material available; it comes directly from supply chain packaging with minimal contamination. Plastic film, similarly, is clean stretch wrap and polythene with good recyclate value if properly segregated. A distribution centre that is not baling these two streams separately and selling or arranging free collection for the bales is paying for the disposal of material that has commercial value.
Gradeall manufactures baling equipment for distribution centre applications from Dungannon, Northern Ireland. The GH600 and GH500 horizontal balers address high-throughput distribution centre requirements. The GV500 and G-ECO 500 vertical balers serve mid-range distribution operations. The twin-chamber baler and multi-materials baler handle two-stream processing efficiently. With nearly 40 years of manufacturing experience and equipment in over 100 countries, Gradeall’s team understands distribution centre waste management at every scale.
The starting point for distribution centre baling specification is throughput: how many tonnes of cardboard and film does the operation generate per operating day?
Estimating cardboard generation. A rule of thumb for distribution centre cardboard is approximately 5 to 15 kg of cardboard per inbound pallet, depending on product type and pack format. A distribution centre receiving 200 pallets per day generates approximately 1,000 to 3,000 kg (1 to 3 tonnes) of cardboard per day. This estimate is a starting point; actual measurement from a waste audit or skip weight records gives a more accurate figure.
Estimating film generation. Stretch film consumption varies by pallet configuration and the number of wrapping passes used. A reasonable estimate for pallet wrap film is 0.3 to 0.6 kg per outbound pallet wrapped and a similar amount from inbound wrapping removed during goods receipt. For a distribution centre wrapping and receiving 200 pallets per day, total film generation is approximately 120 to 240 kg per day.
These estimates indicate that a distribution centre at 200 pallets per day is generating roughly 1 to 3 tonnes of cardboard and 120 to 240 kg of film per operating day, translating to a weekly production (five days) of 5 to 15 tonnes of cardboard and 600 to 1,200 kg of film.
At these volumes, horizontal balers become the specification for cardboard, producing higher throughput and better bale quality than vertical machines can achieve at this scale. The film stream at these volumes justifies a dedicated film baler rather than processing film in a multi-stream vertical baler.
For distribution centres generating over two tonnes of cardboard per day, horizontal balers offer meaningful operational and commercial advantages over vertical machines.
Throughput. A horizontal baler at distribution centre scale processes cardboard continuously from a conveyor infeed, producing bales without the discrete loading cycles that limit vertical baler throughput. For a five-day operation with eight hours of active baling time per day, a horizontal baler producing 10 to 20 tonnes per operating hour can process the entire day’s cardboard generation in a single baling shift.
Bale quality. Horizontal balers produce large-format, high-density bales (often 500 to 700 kg) that are preferred by paper merchants for their transport efficiency. The higher income per collection vehicle load from dense, large bales may produce better collection terms than lower-density vertical baler output.
Continuous infeed. A horizontal baler can be fed by conveyor directly from the goods receipt area, eliminating the manual loading that vertical balers require. For operations with cardboard generated across extended goods receipt shifts, conveyor-fed horizontal baling processes the material as it is generated rather than requiring accumulation and batch processing.
Gradeall’s conveyor systems integrate with the baling equipment, providing the infeed path from goods receipt cardboard breaking to the baler loading point.
For smaller distribution centres generating under two tonnes of cardboard per day, the GV500 provides vertical baling capacity at a lower capital cost than a horizontal system, with throughput that matches the volume requirement.
Plastic film from pallet wrapping is the second significant recyclable stream in distribution centre waste, and it requires specific operational handling to produce commercially valuable bales.
Segregation at source. Film is cleanest and most valuable when it comes directly from pallet wrapping operations before any contact with dirty floors, product residue, or other waste streams. Goods receipt operatives who remove stretch film from inbound pallets should deposit it directly into a designated film collection vessel positioned at the goods receipt workstation, not drop it on the floor or mix it with cardboard.
Air removal before baling. Stretch film as removed from a pallet contains significant trapped air. Film loaded into a baler without de-airing produces low-density bales with poor commercial value. A simple de-airing procedure (pushing the film down into a collection bag or using a film rolling station before loading) removes air and produces denser bales. Some distribution centres use a film wind-up station that rolls the film as it comes off the pallet, producing a compact roll that loads into the baler efficiently.
Dedicated film baler or multi-stream baler. For distribution centres generating significant film volumes (over 200 kg per day), a dedicated film baler produces better bale quality and commercial outcomes than processing film in a multi-stream machine alongside cardboard. For operations where film volumes are below this threshold, the twin-chamber baler runs film and cardboard simultaneously in separate chambers without compromising bale quality for either stream.
The efficiency of a distribution centre baling operation depends significantly on the bale storage and collection logistics. Bales that are stored well and collected efficiently add value; bales that accumulate in disorganised storage, get damaged by forklift contact, or mix material types create commercial problems.
Dedicated bale storage. A defined bale storage area, separate from active operational areas, with floor markings or physical separation between cardboard bales and film bales, prevents cross-contamination and allows accurate inventory of bales awaiting collection.
Collection contract and frequency. The collection frequency should match the bale production rate. A distribution centre producing 20 cardboard bales per day needs daily or twice-daily collection rather than the weekly collection appropriate for a small retailer. Negotiate collection frequency with the merchant before the baling operation commences; discover a frequency mismatch after the bale storage area is overflowing is an operational problem.
Waste transfer documentation. Each bale collection requires a waste transfer note. In a high-volume operation with frequent collections, a pre-agreed template note with only the variable quantities to complete per collection is more practical than completing a full note from scratch at each collection event.
Distribution centres that handle product returns generate additional cardboard and packaging waste from the returns stream. Returns packaging is often damaged, mixed, or contaminated with product residue to a greater degree than inbound delivery packaging. Assess returns packaging separately from inbound packaging to determine which elements are suitable for baling and which need to go to general waste.
Clean, intact cardboard from returns outer cases is baling-suitable. Packaging contaminated with returned product, heavily damaged cardboard from crushed returns, or packaging of mixed types that can’t be easily sorted may be more economically managed as general waste than sorted and baled.
“Distribution centres are where the baling investment case is most compelling, because the volume is high, the material is clean, and both streams, cardboard and film, have genuine commodity value,” says Conor Murphy, Director of Gradeall International. “The combination of disposal cost saving and bale income at distribution centre scale produces payback periods measured in months rather than years.”
Contact Gradeall International to discuss baling equipment specification and layout planning for your distribution centre.
A conveyor system collecting cardboard from multiple goods receipt bays and feeding a central horizontal baler is the most efficient configuration for large distribution centres. For smaller operations with two or three receipt bays, a cardboard trolley circuit collecting broken-down cardboard from each bay to a central baler on a regular schedule achieves adequate throughput without conveyor investment. Contact Gradeall International for guidance on conveyor integration with baling equipment.
Separately. Mixed cardboard and film bales have lower commercial value than single-material bales and may be rejected by some merchants. The modest additional operational effort of maintaining segregated streams is repaid in higher bale prices and more reliable collection arrangements.
Target bale weights that your recycling contractor or paper merchant accepts and that your forklift can handle safely. For horizontal balers producing mill-size bales, 500 to 700 kg is typical. For vertical balers, 300 to 500 kg is typical. Confirm the acceptable bale weight range with your collecting merchant before specifying the machine.
E-commerce peaks multiply cardboard volumes significantly over a short period. Ensure the baler specification handles the peak throughput requirement, the collection contract allows increased frequency during peak periods, and the bale storage area has capacity for a higher accumulation rate if the collecting merchant cannot respond immediately to peak-period production.
