This article takes an in depth look at trash compactors and their use.
You will learn more about topics such as:
A compactor is a machine designed to compress, reduce, and compact a variety of materials through hydraulic, mechanical, or pneumatic force. The initial steps in the compacting process are the collection of the material to be compacted. This is completed using various means depending on the application and includes manual loading, loaders, conveyors, or other dumping methods.
Once the compactor reaches a certain level, it is activated to compress the material into a smaller form by forcing out air, fluids, and moisture. The main goal of a compactor is to compress waste materials into a container to increase the amount of trash a container can hold and hauled per load.
Steps to the compacting process:
The process of compacting reduces the volume of waste and its footprint, allowing a more convenient and economical method for removing it. Trash compactors are an environmentally compliant method for removing waste cleanly and safely. The reduced volume and mass of waste decreases its space in a landfill.
In modern industry, an industrial trash compactor is a must in order to keep up with demand and changing regulations regarding pollution and proper disposal of waste materials. Every industry produces its own unique type of waste that has to be handled in a specific way. The type of waste is the determining factor regarding the type of compactor. In essence, there is a compactor to meet the needs of waste products.
Types of Waste:
The general categories for compactors:
An auger compactor has a rotating auger located in the feeder or waste collector. As waste material is fed into the collection chamber, the auger or screw crushes it and moves it into a second container. Auger compactors have the strength, endurance, and power to crush very large items, much like a pre-crusher compactor.
Auger compactors can crush dry waste making them an ideal solution for a wide variety of commercial and industrial uses. Large bulky waste is significantly reduced as it is crushed by the movement of the auger. Auger compactors are ideal for dry waste and should not be used with liquid waste.
A bag compactor is designed to compress bags into a removable bin. They are designed to control the dust created by the compacting of plastic and paper bags. Bags are loaded into the bag compactor, which pulls in any dust or contaminants. The bags are then compressed into a removable bin that can be lined with a plastic bag for easy transfer to a dumpster. Bag compactors come in sizes that range from 50 gallons to 150 gallons.
Chute fed compactors are used in multistory buildings, hospitals, and resorts and have a two or three yard front or rear load container. They have a chute hopper that receives trash that sends it to the compacting chamber. A sensor detects the quantity of the waste material and activates the compression cycle of the ram. When the compactor is full, an alert light lets the operator know to unload the compactor. The design of chute fed compactors is a feed option that would be built to go with a compactor, wet or dry.
Portable trash compactors are located inside buildings and are smaller than stationary, vertical, or self-contained compactors. They can handle gallons of trash and can be moved to be positioned in different locations. They have a built-in cart for the safe removal of the compacted waste. The compacted material is formed into a block in the cart in the lower part of the compactor. It is loaded through a front latched door and compacts the waste material into the cart.
A pre-crusher is a unique form of compactor that compacts materials before they can be compacted. Their purpose is to smash waste materials before they are compacted to reduce the volume of the trash. The majority of the items that are put through a pre-crusher are large and bulky such as furniture, drums, and pallets.
If a large item is not broken down before being placed in a compactor, it will leave gaps and open space in the compactor bin. A pre-crusher breaks down large items to ensure that waste material is tightly packed. They are designed for use in heavy duty work environments such as construction and industrial manufacturing.
A function of pre-crushers is to destroy products, materials, and items that could possibly be used for resale. The crushing process destroys any value that a product may have.
Self-contained compactors are used for compressing wet waste and waste that generates liquids. The compactor and container are one unit that can be hauled away to be emptied at a landfill. The tight seal of a self-contained compactor provides a clean method for the removal of any type of waste material. When the unit is full, the compactor and container are taken to a landfill, where the waste is emptied.
A unique feature of self-contained compactors is their power pact, which is remote and not connected to the compactor or container. It can be positioned in various places with the most common location being next to the compactor.
Wet waste is loaded into the compactor where the ram crushes it to 75% smaller than its original volume. The mechanism of the compactor is fused to a container that holds the waste and prevents leakage. Self-contained compactors are liquid tight for the safety and protection of workers and the environment.
Stationary compactors are designed for mid to large volume operations that produce dry waste materials. They are mounted on site with a connected container that is removed and dumped at the local landfill. Applications include department stores, warehouses, fulfillment, and manufacturing to name a few. The compactor can be set up to be fed by hand, cart, or conveyor. Sales representatives offer guidance and advice as to the placement, design, and set up of stationary compactors.
The design of stationary compactors allows for the compaction of dry waste. Materials stationary compactor compact include cardboard, mixed paper, plastic, and textiles all of which are recyclables.
A Vertical Compactor is a small compactor that compacts trash vertically into a dumpster sized container that can be emptied by a collection truck. Vertical compactors have a small footprint and are ideal for use in locations with limited available space. Waste is loaded from the front or back of the compactor
As a hand fed compactor, vertical Compactors are suitable for wet or dry waste with low to mid volumes. An 80% full light lets users know that the container needs to be emptied. Vertical compactors can be used with multiple containers that can be switched when full between dumps.
Trash compactors have become an essential part of several industries to reduce the volume of waste produced from production, record keeping, shipping and receiving, and various manufacturing processes. As concern for the condition of the environment grows, the use of compactors as a means for reducing the size of loads dumped into landfills has increased.
The simple process of crushing waste and compressing it has had a significant impact in limiting the size of waste material and reducing the cost of waste removal. Since the introduction of the first compactor in the s, their use has grown from a convenience to a vital part of environmental protection and sustainability. Trash compactors protect workers from the fumes of waste material and enhance an environment by providing a clean solution to waste removal.
The use of compactors can be categorized by the industries that depend on them. In general, every type of business produces some form of waste material to be removed and dumped. The size and volume of work of a business increase the need for the use of a compactor.
The widest use for compactors is found in various retail, restaurant, and hotel operations that produce a variety of waste products from packing materials and boxes to leftover food. Years ago, a major concern for commercial enterprises was the types of rodents and vermin that lived off the piles of waste their businesses produced. The implementation and use of compactors have eliminated the problem while decreasing the footprint that commercial waste produces.
Commercial compactors are normally vertical and are placed either inside or outside, depending on the needs of the business. Vertical compactors come in a variety of sizes such that they can be placed in a work area or outside the back door.
The healthcare and medical industries have a completely different type of waste material that is potentially dangerous and harmful. The disposal of medical instruments and tools requires careful care and planning to protect waste management personnel from being infected by needles, swabs, and other used instruments. The waste materials are carefully managed and monitored and equipped with alerts warning of dangerous or hazardous conditions in the compactor.
The design of a medical waste compactor necessitates the employment of containment, storage, and transportation to prevent exposure of waste to the public. Healthcare professionals and local health departments generally accept these requirements.
Industrial compactors are larger and capable of processing greater quantities of waste material. An emphasis for modern industrial operations is the collection of recyclable and reusable materials. A popular method in the recycling effort is the single stream self contained compactor that separates recyclable material from landfill materials. Paper, aluminum, and plastics are placed in one container, while landfill waste such as wet and food waste is placed in the other.
Industrial operations use a wide selection of compactors with stationary and self-contained being the most common.
There is a growing demand for schools to recycle paper, furniture, plastic bags, toner cartridges, computers, and electronic devices to save landfill space and remove pollution from the environment. One method that has become a practical solution for school recycling is the indoor hopper, which is ideal for use in busy corridors and hallways. Indoor hoppers are on casters for easy mobility and placement. They are designed to be front or rear loaded for easy access. When full, they can be wheeled to the hauler area to be unloaded.
The few uses for compactors listed above are a small fraction of the applications where compactors are used. Airports depend on compactors to keep surfaces clean. The food industry relies heavily on self-contained compactors for compressing and decreasing their volume of waste as well as preventing infestations from rodents and vermin. Any place that has waste, whether it be large or small, depends on a compactor to reduce the volume of its waste material and diminish its waste footprint.
The many configurations of compactors have a single goal: to compress waste material into a compact size for removal or recycling. From this general principle, manufacturers have developed a variety of methods and techniques that are designed to meet the needs of specific materials and applications.
In the majority of cases, the compression process is initiated by a ram that is powered by a hydraulic or pneumatic motor. The size, force, and power of the system depends on the types of materials to be processed and the size of the chamber.
The HPU supplies the power to the compactor and consists of an electric motor, pump, hydraulic directional valve, a pressure control valve, and a reservoir. To avoid the hazard of electrical shock, the power unit is not connected to the compactor box.
The ram is the part of a trash compactor that compresses the waste material. It is driven by the force of a hydraulic motor that transfers fluid under pressure to move the ram. In essence, the ram of a trash compactor is similar to a piston on an automobile. It is connected to a shaft, which varies in size according to the type of trash compactor and the size of the waste container compartment.
The movement of the ram is governed by different mechanisms, which can be an on and off switch activated by an operator or an automatic switch when the compactor reaches a specified load level. The thickness, weight, and shape of the ram is determined by the design of the compactor. Hydraulic motors are used due to the efficiency at which they can supply compressive force.
Rams move horizontally or vertically and are guided along the waste chamber or may have lubrication. The movement of the ram is quiet and efficient.
The compression chamber is where waste material is gathered and placed for processing. It is the part of a trash compactor where the ram moves to compress the collected material. The chamber is the largest part of a trash compactor and is accessible through the hopper with large trash compactors and directly accessible in smaller trash compactors.
Using the piston analogy, the ram moves along the compression chamber and is contained within its walls. Of the various parts of a trash compactor, the compression chamber is the sturdiest and most durable. It is tightly sealed with walls made of steel. Although the compression chamber is not delicate or fragile, there are restrictions in regard to the types of materials it may contain, such as hazardous chemicals, aerosol containers, explosive materials, certain foods, and items with strong odors, noxious smells, or poisonous vapors.
The force and power of the compactor is created by the hydraulic pump that forces the ram against the trash. Hydraulic fluid in the pump pushes a piston that pushes the ram. When a sufficient amount of pressure builds up along the surface of the ram, as the trash is compacted into a container, the piston retracts, pulling the ram back to allow more trash to be loaded in the chamber.
In the image below, the hydraulic pump can be seen at the top of the image of a vertical trash compactor.
The control panel of a compactor includes a variety of switches and buttons designed to enable easy and safe use of the compactor. The key feature of the control panel is safe operation since it contains more than a simple on and off switch. It is a hydraulic power unit with a control station that can be mounted inside or outside depending on how the machine is fed. Control panels can be a panel box like the one pictured but are usually remote button stations.
The majority of industrial compactors have a key that is required for access to the controls. Once access has been granted, the operator can turn the compactor on and off. Three indicator lights display the status of the compactor. A red light indicates that the compactor is full and should be emptied. When the ram is in motion, a green light will appear on the panel. For some models, a yellow light indicates that a cleaning or deodorizing agent is being applied.
As with all forms of large equipment, safety is the key to the operation of a trash compactor. Before workers are allowed to operate a trash compactor, they are trained by qualified personnel and only allowed to operate the compactor after being observed. The control panel is the final line of defense of a trash compactor that guarantees the safety and protection of personnel.
An essential feature of all large compactors is the emergency stop button that halts the operation of the compactor regardless of where it is in its cycle. This is a necessary safety feature, especially for large industrial compactors such as pre-crushers, self-contained, and stationary compactors that handle large volumes of waste and crush it with great force.
Regardless of the size of a business, waste management is a key component of its operation. In modern society, this particular aspect of business has gained greater significance due to the sustainability movement and the need to be eco-friendly. Inappropriate, irresponsible, and improper waste management can threaten the existence of a business and lead to it being shut down.

The easiest to use and widely available method for waste management is the trash compactor that comes in sizes, designs, and configurations to fit the needs of any business. A small investment in a compactor can lead to multiple benefits in business operations.
The proper management of waste and its control can lower the costs of doing business. The compacting of waste, garbage, and refuse reduces the need for its collection and having bins and containers for storing it for pickup. The use of a trash compactor removes the need for trash bags or other such measures.
The consolidation and compression of trash lowers the waste footprint of a business and diminishes the number of trips to the landfill to unload and empty trash. This saves on the costs of trash pickup and the necessary labor.
In the present business environment, every means is being taken to cut down on the time used for a certain job or project. The elimination of the concerns for waste management can be a simple and efficient method for eliminating one major issue. This can be facilitated by installing a compactor system, which cuts down on cost, eliminates wasted time, and provides a smooth and economical solution.
The size of a business' footprint is a constant concern since the greater the size of the footprint, the greater the cost. Trash compactors can reduce the size of a company's footprint by disposing of bulky and space consuming waste materials. Large pieces of waste matter can be reduced making the waste matter easier to handle such that it takes up less space.
The installation and use of a compactor are easy, convenient, and efficient. Once positioned, the simple pressing of a button activates the powerful mechanism that compresses, flattens, and crushes large quantities of useless or recyclable materials. Regardless of how easy it is to operate a trash compactor, its operation is always restricted to trained personnel.
There are several factors related to the accumulation of trash, the most important of which is its toxic and harmful nature. When waste is allowed to set and be untreated, it rots and produces odors, which can be harmful and possibly dangerous. Trash and waste can easily be disposed of in a trash compactor that contains the odor and compresses the material. Additionally, there are restrictions on the types of waste that can be compressed such as toxic chemicals, potentially explosive items, and material that can produce toxic vapors or odors.
The very old, tried, and true method of throwing trash in a bin or trash can until it overflows has been found to be ineffective and diminishes the appearance of a business' property. A major benefit of a compactor is its ability to take those overflowing piles of garbage and trash and compress them to reduce their volume for easy disposal. The appearance of the exterior of a business is left looking spruced, clean, and well organized.
Society has become acutely aware of how a business deals with environmental issues and tends to support those businesses that show concern for sustaining and protecting the environment. This single factor can be the turning point in how a business appears to the public. Concern for the environment can be seen everywhere in the United States with recycling programs by trash collecting companies and sustainability programs by major corporations.
These many efforts create a positive public image that encourages customers to support a business. Implementing a compactor system is a vital step in a program for improving how a company is viewed.
Of all the many benefits of instituting a compactor program, environmental awareness is the most vital. Going Green is the slogan of the century and one that all concerned businesses have placed at the forefront of their objectives. A compactor reduces the size of the waste sent to a landfill and has the potential to assist in separating recyclable materials from landfill waste. It is the optimum environmental mechanism that removes contaminants and safely constricts and controls them.
As restrictions in the UK ease and businesses begin to operate at full capacity the age-old problem of waste rears its ugly head! Unfortunately, all businesses produce waste that can't be recycled. This waste is typically put into bins and skips and sent to landfill. On average waste collected can cost from £160 ' £500 per tonne disposal. This cost can really start to add up. There is a fantastic cost saving opportunity for your business as compacting your waste can drastically reduce the number of pickups required, saving your business thousands of pounds a year. Our Compactors are able to reduce waste volumes by up to 5:1.
Let's do the maths, if you compact five times more waste into your skip, you're going to reduce your tonnage cost down to £160 per tonne.
Waste compactors are typically used by organisations with medium to large volumes of low-value mixed waste. They're designed to compress this waste to reduce the volume of space it requires. In turn, fewer waste collections are required, which leads to cost savings. In order to complete this task compactors deploy a powerful compaction ram that delivers up to 36 tonnes of force. Typically, these machines handle the disposal of general black bag waste, wet food waste, broken pallets, plastic wrapping, furniture and window frames. It's also possible to compact plastic, paper and cardboard, however, if you have a sufficient stream of these recyclables you may benefit more from a baler.
Compactors are typically sited outside and are fed by hand, conveyor belt, bin lift or forklift truck. This minimises the amount of waste handling required, thus reducing labour costs.
Here at Landfill Alternatives we sell and lease a wide range of Waste Compactors. These fall into three categories; Static, Portable and Specialist. We're often asked what the difference is between a static and portable Compactor. This article will explain the key differences, but first, we'll start by outlining the general benefits of compactors.
The key purpose of compactors is to minimise the volume of waste. This translates to fewer collections ensuring you're disposing of waste in the most cost-effective manner. However, in addition to this, they also offer a host of other benefits such as;
Compactors provide an efficient system for disposing of waste, that results in fewer collections and minimises the
number of rubbish bags, and handling required. This results in a significant cost saving for your business.
Compactors eliminate any chances of unauthorised dumping of waste. This ensures you're only paying to dispose of what your business produces.
Overflowing bins can be unsightly, unhygienic and pose a safety hazard. They can also attract rodents, emit unpleasant odours and waste can escape making the site look untidy. A compactor can eliminate all of these issues.
As compactors can be loaded by bin tippers, conveyor belts and dump trucks they require very little waste handling. This frees up your labour force enabling them to focus on more essential tasks.
With fewer waste collections there are less trucks on the road emitting greenhouse gases. Compacted waste also takes up less space in landfills where space is increasingly limited.
Waste collection vehicles onsite pose a hazard, they also require valuable labour time to organise and supervise. Therefore, the less contractor traffic on site the better.
Now we've established the benefits of compacting waste it's time to discuss the differences between static and portable compactors.
Static Compactors are bolted to a hard surface in your yard with a 35yd or 40yd enclosed roll-on roll-off skip attached to it.
Static compactors offer the following advantages;
Our largest compactor can hold up to 12T of waste. Therefore if you are processing large volumes or light waste they may be more suitable.
When your skip is full the contractor will change your skip over with an empty one straight away meaning there are no waiting times.
Our static compactors are more customisable. The machine can be loaded from different sides, with different size and shaped hoppers depending on your needs.
However, it is also important to consider the following;
Machines are bolted to the floor, once they're installed they are more difficult to relocate.
Static compactors do not have a watertight seal. As a result, if you're disposing of wet waste you'll need a portable compactor.
Typically smaller in size, portable compactors are placed in the yard and then lifted onto a truck once full. We have two different sizes of portable compactor for sale & lease hire: 10 m/3 and 20 m/3.
Portable compactors offer the following advantages;
These units would fit within an average car parking space. If space is limited our portable compactors can be a viable option.
Naturally, these units can be moved around the yard, offering you more flexibility if your space requirements change.
The majority of our portable compactors offer a watertight seal and self-cleaning blades. This makes them perfect for the disposal of wet waste. This keeps your site clean and hygienic.
However, it is also important to consider the following;
With a smaller capacity, these units fill up quicker. If you have a high volume of dry waste you may be best suited with a static unit.
When your unit is full, it will be taken away to be emptied. This results in downtime during the changeover period.
If you're considering purchasing or leasing one of our compactors you should consider the following;
Typically, in order to achieve a cost saving a business should be disposing of 5 litre wheelie bins per week.
If you're disposing of wet waste, you'll require a sealed portable compactor. We offer both static and portable options for dry waste.
Including the skip, our largest compactor is approximately 10m in length. Factoring in the additional access space required for the removal truck, these machines can occupy a significant amount of space. Therefore, if space is limited, you may be better suited with a portable compactor.
If you dispose of large amounts of paper, cardboard or plastic you may benefit from a Recycling Baler.
