Maintenance of waste compactors

Basis for efficient waste management in the company

Waste compactors are indispensable devices in many industries as they reduce waste volumes, cut costs and contribute to sustainability. Regular maintenance is essential for these devices to work reliably and efficiently. In this article, we take a look at the different types of waste compactors, how they work, their benefits and the maintenance tasks involved.

Types of compactors and how they work

Vertical presses

Functional principle:
Vertical compactors compact waste using a vertically moving pressing plate. The waste is filled into a chamber and the pressing plate presses onto the material from above.

Advantages:

  • Compact design, ideal for smaller businesses
  • Low space requirement
  • Simple operation and installation

Required maintenance tasks:

  • Checking the hydraulics: checking for leaks or damage
  • Cleaning the press chamber: regular removal of residues
  • Check the electrical components: make sure that the control unit and motors are working properly
  • Lubrication of moving parts: Reduction of wear

Horizontal presses


Horizontal balers compact waste horizontally in an output chamber. They often have automatic feeding systems and are suitable for large quantities.

Advantages:

  • Efficient for high waste volumes
  • Automatic loading possible
  • Optional connection to conveyor belts or waste garbage cans

Required maintenance tasks:

  • Maintenance of the conveyor belts: Make sure that there are no blockages or damage
  • Checking the hydraulics and pneumatics: checking for leaks and correct pressure
  • Cleaning the feed and press chamber: Prevention of material jams
  • Software updates: ensuring that automation works smoothly

Screw presses

Functional principle:
Screw balers use a rotating screw that continuously compacts waste and dispenses it into bales or containers.

Advantages:

  • Continuous operation without interruptions
  • Suitable for liquid-contaminated waste such as food waste
  • Low energy consumption

Required maintenance tasks:

  • Checking the screw: Check for wear or damage
  • Cleaning the dispensing area: Make sure that no blockages occur
  • Replacement of wearing parts: In particular, replace seals and bearings regularly
  • Checking the drive motor: Ensure that the power remains constant

Baling presses

Functional principle:
Baling presses compress waste (e.g. paper, cardboard, plastics) into compact bales that can be easily stored or transported

Advantages:

  • Reduction of volume for storage and transportation
  • High compaction, ideal for recycled materials
  • Flexible for different types of waste

Required maintenance tasks:

  • Check the binding devices: Ensure that the balls are tied correctly
  • Checking the hydraulic cylinders: preventing pressure loss or leaks
  • Cleaning the filler opening: preventing blockages
  • Regular calibration: make sure the balls are the right size and density

General maintenance tasks for all compactors

  • Safety check: Regularly check all safety devices such as emergency stop switches and protective covers.
  • Check the power supply: Check cables, plugs and fuses.
  • Regular inspections by specialist personnel: Preventive maintenance to avoid breakdowns.
  • Staff training: Ensure that the operator uses the machine correctly and in accordance with the instructions.
  • Keeping a maintenance log: Documentation of all maintenance measures carried out.

What is important for the safe and reliable use of waste compactors?

The safe and reliable use of waste compactors is essential to prevent accidents at work, optimize machine performance and ensure a long service life. Here are the key aspects that should be considered:

Staff training and instruction

  • Operator training: Employees should be fully trained in the operation of the compactor, including its function, safety features and maintenance requirements.
  • Knowledge of the dangers: Information about possible risks such as crushing points, overheating or electrical hazards.
  • Emergency measures: Employees should know how to stop the waste compactor in an emergency and switch it off safely.

Compliance with safety regulations

  • Safety devices: All safety covers, sensors and emergency stop switches must be in working order and must not be tampered with.
  • Safety distances: The workplace around the waste compactor should be free of obstacles and a safe distance from the compactor must be ensured at all times.
  • Hazardous substances: Additional safety measures are required when compacting special types of waste (e.g. chemicals or flammable materials).

Regular inspections and maintenance

  • Maintenance schedule: The compactor should be serviced regularly in accordance with the manufacturer’s recommendations. This includes checking the hydraulics, electrics and mechanical components.
  • Wear check: Moving parts, seals and hoses must be checked regularly for wear and replaced if necessary.
  • Cleaning: Waste residues and dust deposits must be removed regularly to prevent blockages or damage.

Operation according to the manufacturer’s specifications

  • Observe the maximum capacity: The press must not be overloaded, as the hydraulics may overload and cause damage.
  • Correct waste types: Only compact the types of waste approved for the respective compactor. Incorrect materials can cause damage or dangerous situations.
  • Monitoring during operation: The machine should never run unattended so that quick action can be taken in the event of problems.

Ergonomic and efficient work design

  • Easy accessibility: The working area around the compactor should be designed in such a way that loading and unloading is possible without physical strain.
  • Use automation: For larger quantities of waste, automatic feed systems or conveyor belts can increase safety and efficiency.

Dealing with defects and faults

  • Immediate shutdown: If irregularities such as unusual noises, overheating or error messages occur, the machine should be checked immediately.
  • Qualified personnel only: Repairs and troubleshooting may only be carried out by trained personnel or the manufacturer.

Compliance with legal requirements and standards

  • Occupational health and safety guidelines: The use of the waste compactor must comply with the applicable safety standards, e.g. the requirements of the Ordinance on Industrial Safety and Health (BetrSichV) in the EU.
  • Inspection obligations: Regular inspections by experts or authorized inspectors ensure operational safety.

Emergency management

  • Emergency stop switch: The emergency stop switch must be easily accessible and clearly visible.
  • First aid equipment: A first aid station should be available at the workplace and employees should be trained in first aid.
  • Fire extinguisher: A suitable fire extinguisher should be to hand in case of possible fires, e.g. caused by compacted flammable materials.

By taking these aspects into account, the waste compactor is operated safely, efficiently and sustainably. This not only protects the health of employees, but also ensures a high level of reliability and a long service life for the machine.


What legal obligations exist in connection with the operation of waste compactors?

The operation of waste compactors in Austria is subject to various legal regulations that are intended to ensure both the protection of employees and compliance with environmental standards. Here are the key legal obligations that employers and operators must observe:

Employee Protection Act (ASchG):
