Gradeall International recently delivered a G90 static waste compactor fitted with a bin lift to a large commercial bakery in Glasgow, Scotland. The installation highlights how purpose-built compaction equipment can address highly specific operational requirements — in this case, the need to accommodate a dolav pallet box disposal method while retaining the standard bin lift functionality the customer relied on.
The bakery had been using a dolav pallet box with their previous compactor and wanted to carry that workflow forward without compromise. Gradeall’s in-house engineering team developed a custom dolav pallet box adaptor that slots directly into the standard trunnion bin lift, allowing operators to wheel in a loaded pallet box and empty it into the compactor cleanly and efficiently.
The G90 is a high-capacity static waste compactor designed for commercial and industrial operations that generate significant volumes of compressible waste on a regular basis. “Static” refers to the unit being permanently installed at a fixed location, typically connected to a large external container that collects compacted waste for periodic collection by a waste contractor.
Static compactors like the G90 are suited to facilities where waste volumes are too high for portable units or manual handling, and where a consistent, predictable waste output is operationally important. Bakeries, food manufacturers, distribution centers, and large retail operations are among the most common users.
The G90 itself offers a 90-yard compaction capacity, positioning it between smaller commercial units and the larger 120 and 140-yard models Gradeall also manufactures. Its design prioritizes reliability under continuous use, with a robust hydraulic system and a straightforward operator interface that keeps training requirements minimal.
The G90 is built and engineered entirely at Gradeall’s manufacturing facility in Dungannon, Northern Ireland. That in-house capability is directly relevant to this Scottish bakery installation: when the customer identified a requirement for a dolav pallet box adaptor, the engineering team was able to design and produce one without the delays or constraints that come with outsourced manufacturing.
Standard features of the G90 include a heavy-duty hydraulic ram, a robust charging hopper suitable for bulk waste loading, and the trunnion bin lift system that accommodates standard waste bins. The addition of the dolav pallet box adaptor extends that compatibility to larger pallet-based containers without modifying the core machine or compromising the standard bin lift operation.
A dolav pallet box is a large, box-shaped container typically used in food production and distribution to move high volumes of loose material. In a bakery setting, these boxes are commonly used to collect unsold goods, production off-cuts, and packaging waste.
The challenge with dolav pallet boxes in a compactor application is the mismatch between the box geometry and a standard trunnion bin lift, which is designed for cylindrical or rectangular wheeled bins. Gradeall’s engineers resolved this by designing a dedicated adaptor that allows the dolav to be wheeled directly into the trunnion mechanism. Once positioned, the contents can be tipped cleanly into the compactor hopper, maintaining hygiene standards and eliminating the manual handling that would otherwise be required.
This kind of bespoke adaptation is a direct result of Gradeall designing and building all its machines in-house. The engineering team has the flexibility to develop custom components without the delays or costs typically associated with third-party fabrication.
Commercial bakeries operate with waste streams that differ significantly from general commercial waste. Understanding those differences matters when specifying compaction equipment, and it explains why an off-the-shelf solution often falls short in a food production environment.
Commercial bakeries globally discard enormous quantities of product every year. Industry estimates put the figure at around 30 million tons of bread and baked goods discarded annually across global supply chains. That volume reflects a combination of production over-runs, strict date labeling requirements, retailer returns, and production quality rejects.
At facility level, a large commercial bakery can generate several tons of waste per day, combining organic food waste, packaging materials, flour and ingredient bags, and cleaning waste. The organic fraction — bread, pastry off-cuts, out-of-date product — is the most logistically challenging because it compacts poorly compared to dry waste, generates moisture that can affect equipment, and has strict disposal requirements in many regions.
Packaging waste from bakeries is typically a mix of cardboard, plastic film, and polypropylene bags, all of which respond well to compaction. Managing both streams together — organic waste and dry packaging — often requires a compactor specification that accounts for moisture resistance and easy cleaning.
Bakery waste that reaches landfill creates a well-documented environmental problem. Organic material decomposes anaerobically in landfill conditions, producing methane — a greenhouse gas significantly more potent than carbon dioxide over a 20-year period. Regulatory pressure on landfill disposal has increased substantially across the UK, the US, and the European Union, with landfill diversion targets pushing operators toward compaction, composting, and energy recovery.
For a bakery operating at scale, a static compactor is part of the answer. By compacting waste on-site, the facility reduces the frequency of waste collections, lowers transport emissions, and reduces the total volume going to landfill. The compacted output can be collected in sealed containers that minimize odor and leachate risk during transit.
Beyond the environmental case, operational efficiency is a direct commercial driver. Fewer waste contractor visits mean lower haulage costs. Reduced manual handling means lower labor hours and lower risk of workplace injury. Fewer overflowing bins mean a cleaner, more compliant facility.
Food production environments are subject to stringent hygiene standards, and waste management equipment must fit within that framework. A compactor installed in or adjacent to a bakery production area needs to be easy to clean, resistant to the moisture and organic residue that bakery waste generates, and positioned to avoid cross-contamination risk.
The G90’s hopper design and the bin lift mechanism both address this. The trunnion bin lift allows bins to be emptied without operators needing to handle waste directly, reducing contamination exposure. The custom dolav adaptor in this Glasgow installation extends that hands-off approach to pallet box disposal, which was a key requirement from the customer at the outset.
The bin lift is an integral part of the G90’s functionality for operations that use wheeled waste containers. The standard trunnion mechanism accepts bins within a defined size and weight range, lifts them automatically, tips the contents into the hopper, and returns the empty bin to floor level.
The process is designed for single-operator use. The operator wheels the bin into the lift mechanism, initiates the lift cycle, and the machine handles the rest. This eliminates the manual effort and injury risk associated with lifting and emptying heavy bins, which is particularly relevant in food production environments where waste bins can contain dense, heavy organic material.
The dolav pallet box adaptor developed for the Glasgow bakery slots directly into the standard trunnion mechanism. The dolav — which sits on wheels — is positioned in the adaptor, the lift cycle is initiated, and the contents are emptied into the hopper exactly as with a standard bin.
The adaptor was designed to be removable, preserving the standard bin lift functionality when pallet box disposal is not required. This dual capability was a specific requirement from the customer, who needed both methods available depending on the type and source of waste being processed on a given day.
The G90 is typically paired with a hook lift or chain lift container for waste collection. Compacted waste is ejected from the machine into the container, which is then exchanged by a waste contractor when full. The sealed container design reduces odor during storage and transit, which matters in a food production context where proximity to production areas is common.
Gradeall’s container range includes options suited to the G90’s output, including the C30 hook lift container and the C15 chain lift container. Choosing the right container depends on the site layout, the contractor’s vehicle type, and the frequency of collection required.
The Glasgow bakery installation is a practical example of Gradeall’s broader approach to waste management equipment: designing solutions around the specific operational requirements of the customer rather than asking the customer to adapt their processes to a standard machine.
Gradeall has been manufacturing waste management and recycling equipment at its Dungannon facility for nearly 40 years. The company exports equipment to over 100 countries and manufactures a range that extends from tyre balers and sidewall cutters through to glass crushers, material balers, and the static and portable compactor range that includes the G90.
The in-house design capability underpinning the dolav adaptor is the same capability that allows Gradeall to develop bespoke solutions for customers across sectors, from manufacturing and distribution to healthcare, hospitality, and food production. All machines are designed using finite element analysis and built on-site, which means engineering modifications can be prototyped, tested, and refined within the same facility rather than being outsourced to a third party.
As Conor Murphy, Director of Gradeall International, explains: “When a customer has a specific operational requirement, being able to design and build everything in-house means we can solve the problem properly rather than offering a workaround. The dolav adaptor for the Glasgow bakery is a straightforward example — the customer needed both disposal methods available, and we built a solution that delivers exactly that.”
The G90 sits within a broader static compactor range that runs from 60-yard to 140-yard capacity. Larger operations or those with higher waste volumes may require the G120 or G140, while smaller facilities may find the G60 Supershort a more appropriate specification.
Gradeall also manufactures pre-crush compactors and twin-chamber balers for specific waste streams, as well as portable compactors in the GPC range for operations that require flexibility in waste collection location or container positioning. The right specification for any given operation depends on daily waste volumes, waste stream composition, site layout, and collection logistics.
The bakery context raises questions that apply broadly to food production operations considering static compaction equipment. A few practical points are worth addressing directly.
Moisture management is the primary mechanical consideration. Organic food waste contains significant moisture, and over time, leachate from wet waste can affect equipment components if the machine is not specified for the application. The G90’s design accounts for this in its hopper and drainage configuration, but operators should ensure the installation location allows for appropriate drainage and regular cleaning.
Odor control is a secondary concern in food production environments. A sealed container system, combined with regular collection scheduling, is the most effective approach. In warm weather or high-volume periods, more frequent collection intervals may be needed to maintain acceptable conditions near the machine.
Pest management is a related issue. Compacted waste in a sealed container provides far less pest exposure than open bins or skips, but the loading area around the compactor requires the same hygiene discipline as the rest of the production facility.
Finally, operator training requirements for a static compactor are minimal. The loading and lift cycle process can be covered in a short induction, and the machine’s controls are designed for straightforward daily operation. Maintenance requirements are also low when the machine is used within its design parameters and serviced at recommended intervals.
The G90 is suitable for a wide range of general commercial and industrial waste, including dry packaging materials, organic food waste, cardboard, plastic film, and mixed waste streams. For highly specific or hazardous waste streams, speak with Gradeall’s team to confirm the appropriate specification.
Yes. As demonstrated in the Glasgow bakery installation, Gradeall’s in-house engineering team can develop custom components and adaptors to meet specific customer requirements. All machines are designed and built at Gradeall’s Dungannon facility, which gives the company flexibility that most equipment suppliers cannot offer.
The G90 is typically paired with hook lift or chain lift containers. The appropriate container size depends on waste volumes, collection frequency, and site logistics. Gradeall’s team can advise on the right container specification for a given operation.
A static compactor is permanently installed at a fixed location and connected to an external container. It is suited to high-volume, continuous waste generation. A portable compactor is self-contained and can be repositioned or transported, making it more suited to operations with variable waste volumes or multiple collection points. Gradeall manufactures both types.
This depends on waste volumes and compaction ratios. The G90’s compaction ratio reduces waste volume significantly compared to loose disposal, which means fewer container exchanges and lower collection costs. A Gradeall specialist can model the expected collection frequency based on your operation’s daily waste output.
The standard trunnion bin lift is designed for bins within a defined size and weight range. The dolav pallet box adaptor demonstrates that the mechanism can be extended with custom components where needed. For specific bin compatibility questions, contact Gradeall directly.
Routine maintenance includes hydraulic system checks, hopper and container inspection, and cleaning of the loading area. Maintenance intervals and requirements are specified in the machine documentation. Gradeall also offers servicing and spare parts support for its full equipment range.
The G90 can be installed in covered outdoor locations. The appropriate installation conditions depend on the specific site and climate, and Gradeall’s team can advise during the specification process.
The G90’s capacity can handle substantial volume increases before the machine becomes a bottleneck. For operations expecting significant growth in waste volumes, Gradeall can model the point at which a larger capacity unit — such as the G120 or G140 — would be appropriate.
Gradeall supplies the compaction equipment; waste collection logistics are managed through the customer’s existing waste contractor relationship. Gradeall can advise on container specifications that are compatible with common contractor vehicles.
