Although designed specifically for cardboard and corrugated cardboard compression, most cardboard balers can also bale materials such as paper and plastics. Like other types of balers, cardboard balers can be either vertical or horizontal, depending on the flow of material through the machine. However, cardboard balers are typically vertical as these types of balers are more suited to lightweight waste material compression. They are loaded from an input area at the top end of the baler, and material is fed down into the chamber where it is pounded and crushed into a compact bale.
Although not as common, horizontal balers can also be used for heavy-duty cardboard waste as they are able to bear a greater weight load and usually have an automated motion system. For both vertical and horizontal balers, the compaction of the material uses a hydraulic system which is a more efficient compaction method, and results in less heat being produced during the process.
Some cardboard balers can be designed to produce bales in specific sizes according to a manufacturer’s transport, storage or recycling capabilities. Custom specification in a baler will potentially cost more than a standard model, and while it may save in the long term, it might not be a necessary feature of a baler.
Balers are durable pieces of machinery and are available to be purchased second-hand. Used balers are typically refurbished, which can be a risk, but if the refurbishment process has been done correctly, are able to last for a good number of years. Check for quality of workmanship and material when sourcing used balers to ensure a good deal. For high waste-producing industries such as retail stores or food processing services, the necessity of compacting and baling waste materials is both environmental and economical.
Reducing the bulk of waste makes the process of disposing of it easier and cheaper, and the time required for recycling is also reduced which cuts back on the carbon emissions being released. Complete turn-key recycling systems can be designed around an individual baler, allowing for a fully “green” process. Manufacturers need to be environmentally responsible in their waste management processes, and balers are one way in which to aid their efforts.
