Lisburn & Castlereagh City Council faced a straightforward but costly problem: open-top skips at the Cutts Recycling Centre were filling up faster than they could be collected. The result was a cycle of frequent, expensive skip hires and collection runs that put pressure on an already stretched municipal budget. When the site’s existing static compactor approached the end of its service life, the council recognised the need for a properly engineered, long-term solution rather than a like-for-like replacement.
Gradeall International, a manufacturer of waste management equipment based in Dungannon, Northern Ireland, was brought in to assess the site, design a practical layout, and supply four G120 static waste compactors built specifically for the operational demands at the Cutts. The result was a measurable reduction in skip collections, meaningful cost savings across multiple budget lines, and a foundation for more sustainable waste handling at the site for years ahead.
This case study covers the initial site assessment, the specification and configuration of the equipment, the installation process, and the environmental and financial outcomes the council achieved.
The Cutts Recycling Centre serves a substantial residential and commercial catchment area within the Lisburn & Castlereagh district. Like many council-run recycling sites, it handled a wide range of general and recyclable waste streams, and the volume arriving at the site made efficient compaction a practical necessity rather than an optional upgrade.
Before the Gradeall installation, the site relied on open-top skips as its primary collection infrastructure. Open-top skips have a fixed volume, and once full, they have to be collected and replaced regardless of whether the waste inside has been compacted. On a busy recycling site, that means collection vehicles are dispatched regularly, often to collect skips that are only partially compacted. The cost adds up across skip hire fees, haulage charges, and the fuel and time associated with frequent pickups.
The existing static compactor on site had provided some relief, but it had reached the end of its operational life. Running ageing equipment beyond its service window creates maintenance costs, reliability risk, and downtime that a public-facing recycling centre cannot easily absorb. The council needed to replace the unit and scale up capacity to match actual site throughput.
Before any equipment was specified, Gradeall carried out an initial site visit to understand how the Cutts operated in practice. This stage is critical. Equipment that works well on one site may be poorly suited to another because of differences in access routes, loading configurations, site layout, available footprint, and the specific waste streams being processed.
The Gradeall team reviewed the current waste management setup and identified the key operational pressures: the frequency of skip collections, the types of waste being deposited, and the physical constraints of the site. It was clear that a multi-unit static compactor installation for amenity sites was the right approach, and that the equipment would need to be configured with site-specific adaptations to work efficiently within the existing layout at the Cutts.
The outcome of the assessment fed directly into bespoke site layout drawings, which were produced by Gradeall and submitted to council officials for review and approval before manufacture began. Getting that sign-off before fabrication ensures the final equipment matches both the operational needs and the physical realities of the site.
The G120 static compactor is a heavy-duty unit designed for high-throughput environments like council recycling centres, transfer stations, and large commercial facilities. It is built to handle significant volumes of general waste, compressing material into a connected container to dramatically reduce the number of collection runs required.
Static compactors work by using a hydraulically driven compaction ram to push waste into a sealed or semi-sealed container. As waste is fed into the hopper, the ram activates and compresses the material before retracting to accept the next load. This cycle continues until the container reaches capacity. Because the waste is compacted rather than simply deposited, the containers hold far more material per collection than an equivalent open-top skip, which directly reduces the number of collections needed.
The G120 is well suited to operations that generate consistent, high volumes of general waste over the course of a working day. It handles mixed waste efficiently, and its construction is designed for the kind of sustained daily use that a public-facing recycling centre demands. For a full overview of the range, see Gradeall’s static compactor product category.
Gradeall manufactured the four G120 units with a specific set of features to match the requirements at the Cutts Recycling Centre. These were not off-the-shelf installations. Each unit was adapted to suit the site layout and the council’s operational needs.
Each compactor was fitted with a deck loading walk-on platform, allowing operatives to access the loading area safely and efficiently. The platforms were extended to accommodate the specific spatial constraints at the Cutts, where the standard platform dimensions would not have provided adequate working space. Handrails were installed across the platforms as a standard safety measure.
The hoppers were configured as double-door, manually loaded units. This design allows waste to be deposited directly into the hopper without requiring automated feeding equipment, which keeps the loading process straightforward for site operatives while maintaining the throughput the site needed. The full range of hopper and loading configurations available for static compactors is covered on the options page.
An electronic keypad code startup system was fitted to each compactor. This is a practical feature for any public-facing site: only authorised users with the correct code can activate the equipment, preventing accidental or unauthorised use. At a council recycling centre where the public has direct access to the site, this kind of access control is a meaningful operational safeguard.
The four G120 static waste compactors were manufactured at Gradeall’s facility in Dungannon, Northern Ireland, and installed at the Cutts Recycling Centre in August 2019. The installation followed the site layouts that had been reviewed and approved by Lisburn & Castlereagh City Council officials during the earlier planning stage.
Installing four units simultaneously on an operational recycling centre requires careful coordination. The site needed to remain accessible to the public during the process, and the positioning of each compactor had to align precisely with the approved layout drawings to ensure the extended platforms and double-door hoppers functioned as designed within the available space.
Gradeall’s involvement did not end at installation. The company also took on responsibility for the ongoing servicing and maintenance of the equipment. This is an important consideration for any public sector operator: having the manufacturer provide scheduled maintenance rather than relying on third-party service contracts means issues can be identified and resolved by engineers who understand the specific build and configuration of the equipment.
Installing four compactors rather than one fundamentally changes what a recycling centre can achieve. A single unit creates a bottleneck: when it is at capacity or undergoing maintenance, collections have to revert to the less efficient open-top skip approach. Four units working in parallel distribute the load across the site, reduce the risk of any single point of failure disrupting operations, and allow different waste streams or site areas to be handled by dedicated equipment.
At the Cutts, the four G120 units were positioned to serve different loading areas across the site, matching the spatial distribution of the drop-off points that members of the public use. This means waste moves a shorter distance from the point of deposit to the compactor, which improves efficiency for site operatives and reduces the time each loading cycle takes. Gradeall has delivered similar multi-unit installations at other council sites, including Antrim and Newtownabbey Borough Council and Ystradgynlais Recycling Centre.
The most direct way to evaluate a capital equipment investment like this is to look at what it changed. At the Cutts Recycling Centre, the operational shift from open-top skips to G120 static compactors produced quantifiable savings across several cost categories.
Skip collection frequency dropped by 50%. That single figure captures the core efficiency gain: by compacting waste before it goes into the container, each collection run removes significantly more material. Fewer collection runs mean fewer vehicle movements, lower fuel costs, and less administrative overhead for managing collection schedules.
Skip hire costs fell by 40%. Because the compacted containers last longer between collections and hold more material per run, the number of skip units the council needed to hire and maintain at any given time decreased. The compactors effectively replaced a larger number of passive containers with a smaller number of active, higher-capacity units.
Fuel costs associated with waste transport dropped by 30%. Fewer collection runs mean fewer vehicle movements on and off the site, with a direct reduction in fuel consumption for the haulage contractor. For a council managing a fleet of collection vehicles or working with a contracted haulier, this is a budget line that responds directly to collection frequency.
Skip replacement costs were reduced by 25%. Open-top skips are subject to wear, damage, and general deterioration from use. Compacted containers, which are used less frequently and designed for the higher mechanical stresses of compaction-based collection, have a longer working life. Fewer replacements mean lower capital expenditure on the infrastructure itself.
These savings worked together to improve the council’s operational budget at the site, releasing funds that could be redirected toward other services. That is the practical argument for investing in static compaction equipment: it is not just an environmental measure, it is a financial one.
Static waste compactors can reduce the volume of general waste by up to 75% compared to uncompacted material deposited in an open-top skip. That figure is worth dwelling on for a moment, because it explains why the economics shift so significantly once compaction is in place.
If a site generates 100 cubic meters of waste per week in an uncompacted state, introducing 75% volume reduction means that same waste now occupies roughly 25 cubic meters of container space. Instead of needing multiple skip collections to handle the 100 cubic meters, the site may need only one or two to handle the equivalent 25. At scale, across a year of site operations, that difference adds up to a substantial number of avoided vehicle movements and associated costs.
For Lisburn & Castlereagh City Council, the 50% reduction in skip collection frequency represents a real-world outcome from that volume reduction effect. The theoretical maximum is not always achieved in practice because waste streams vary in density and compactability, but the direction of the change is consistent: compaction always reduces collection frequency, and the G120 at the Cutts delivered that outcome at a scale the council could measure directly.
The financial case for static compactors is straightforward, but the environmental case is equally strong, and for a public sector operator with statutory environmental responsibilities, it matters.
Every avoided collection run represents a vehicle that did not travel to and from the site. Waste collection vehicles are typically diesel-powered, and each run generates carbon emissions from fuel combustion. A 50% reduction in collection frequency translates directly to fewer vehicle movements and, as the Lisburn data confirmed, a 30% reduction in fuel costs. That fuel saving is a proxy for an equivalent reduction in tailpipe emissions from the collection fleet.
Static compaction also has implications for landfill. Compacted waste occupies less physical space in a landfill cell, which extends the useful life of existing landfill capacity. More importantly for methane emissions, by reducing the volume of decomposable material arriving at landfill in a loose, aerated state, compaction can reduce the rate at which methane is generated in the early stages of landfill decomposition. Methane is a potent greenhouse gas, and reducing the volume of organic-rich mixed waste reaching landfill in an uncompacted state contributes to lower overall site emissions.
For councils under pressure to demonstrate progress against environmental targets, the case study at the Cutts Recycling Centre provides concrete, verified data points: reduced vehicle movements, lower fuel consumption, and a more efficient use of landfill space. For a wider look at how Gradeall equipment supports council sustainability goals, see the guide to how balers and compactors support council recycling programs.
Following the successful installation at the Cutts, Lisburn & Castlereagh City Council identified several directions for further improvement in its approach to waste management and environmental sustainability.
The council expressed interest in adopting more advanced waste sorting and processing technologies to improve recycling rates and reduce the proportion of material going to general waste disposal. Static compaction addresses the logistics of waste removal efficiently, but the bigger environmental prize lies in separating recyclable materials before they reach the compactor. Better sorting technology upstream of the compaction stage means more material is recovered for recycling and less ends up in landfill containers at all.
The council also identified circular economy principles as a priority. Encouraging local businesses and organisations to reduce waste generation at source, extend the lifespan of products, and improve material recovery means addressing the waste stream before it reaches the recycling centre rather than after. Static compaction at the Cutts is one element of a broader system, and its effectiveness is amplified when it operates alongside upstream waste reduction initiatives.
Community engagement was identified as another priority. Public-facing recycling centres serve as a visible interface between the council’s environmental commitments and the behavior of local residents. When a site operates efficiently and cleanly, it reinforces the message that waste management matters and that the infrastructure exists to support responsible disposal. The Gradeall Intelli-Fill system is one example of how real-time fill monitoring can support that kind of efficient, clean site operation.
The Lisburn & Castlereagh case study illustrates the broader argument for static compaction at council-operated recycling centres. The combination of volume reduction, lower collection frequency, reduced transport costs, and improved site efficiency makes static compactors a sound investment for any site handling consistent volumes of general waste.
Council recycling centres face specific operational pressures that make compaction particularly valuable. They are public-facing, which means maintaining a tidy, functional environment is important for public confidence and compliance with site regulations. They operate on fixed budgets, which means reducing operating costs through equipment efficiency directly improves what the council can deliver elsewhere. And they carry environmental obligations, which means demonstrating measurable progress on emissions and landfill diversion is not optional.
A G120 static compactor addresses all three pressures. It keeps waste contained and compressed rather than accumulating in open-top skips. It reduces collection frequency and associated costs. And it contributes to measurable reductions in vehicle movements and fuel consumption.
The Gradeall approach at the Cutts — starting with a site visit, producing layout drawings for council approval, manufacturing to site-specific specifications, installing across an operational site, and providing ongoing maintenance — reflects what a properly managed equipment installation looks like in practice. The savings the council achieved were not accidental; they were the result of equipment correctly specified and configured for the site’s actual needs. Further examples of this approach can be found in the council amenity site case study and the G120 installation at Larne Redlands.
Gradeall International manufactures static and portable compactors, tyre balers, sidewall cutters, glass crushers, and a range of waste processing equipment at its facility in Dungannon, Northern Ireland, and exports to over 100 countries worldwide. For operations considering static compaction, the starting point is always an honest assessment of the site: volume throughput, physical layout, access constraints, and the waste streams being handled. That assessment determines what equipment is right, how it should be configured, and what outcomes a realistic investment case should project.
For further reading on how councils are using Gradeall compaction equipment to improve recycling centre operations, the guide to optimising council recycling programs covers the wider decision-making framework in detail.
The council’s existing static compactor at the Cutts Recycling Centre had reached the end of its service life, and the site relied heavily on open-top skips that were filling up too quickly. Frequent skip collections were generating high costs. The council needed to replace the ageing compactor and scale up the site capacity to match actual waste throughput.
The G120 is a heavy-duty static waste compactor manufactured by Gradeall International. It uses a hydraulically driven compaction ram to compress general waste into a connected container, dramatically reducing the volume of material per collection run. It is designed for high-throughput environments such as council recycling centres, transfer stations, and large commercial facilities.
Each of the four G120 units at the Cutts was fitted with a deck loading walk-on platform extended to match the specific site layout, double-door manually loaded hoppers, handrails, and an electronic keypad code startup system to prevent unauthorised use. The equipment configuration followed site layouts reviewed and approved by council officials before manufacture.
Lisburn & Castlereagh City Council achieved a 50% reduction in skip collection frequency, a 40% reduction in skip hire costs, a 30% reduction in fuel costs associated with waste transport, and a 25% reduction in skip replacement costs. These savings were achieved across the site’s annual operating budget.
Static compactors can reduce the volume of general waste by up to 75% compared to uncompacted material. The actual figure varies depending on the density and composition of the waste stream, but compaction consistently delivers substantial volume reduction, which is the mechanism behind the reduction in collection frequency and associated costs.
The reduction in skip collection frequency produced a corresponding reduction in vehicle movements to and from the site, with a 30% reduction in associated fuel consumption. Fewer vehicle movements mean lower carbon emissions from the collection fleet. The installation also contributes to more efficient use of landfill space by ensuring waste is compacted before disposal rather than deposited loosely.
Yes. Gradeall provides servicing and maintenance for the equipment it installs. For the Lisburn installation, this means the council has ongoing support from the manufacturer rather than relying on third-party service arrangements. Having the manufacturing team involved in maintenance means issues are identified and resolved by engineers who understand the specific configuration of the installed units.
Following the successful installation at the Cutts, Lisburn & Castlereagh City Council identified further priorities, including adopting advanced waste sorting and processing technologies to improve recycling rates, advocating for circular economy practices with local businesses and organisations, and engaging with the community to encourage sustainable waste disposal habits.
