Find out how food waste processing equipment is leading the change to sustainable food waste processing and greening your waste. It is a hidden secret that the waste treatment technology in food waste treatment equipment and residual municipal waste equipment is very important.
First, just think how much waste food these machines have to process!
Did you know that approximately one-third of all food produced globally goes to waste? In the United States alone, the Environmental Protection Agency (EPA) estimated that food waste amounted to 35 million tons in 2018.
This staggering amount not only has environmental implications but also economic and social ones. Fortunately, waste de-packaging equipment can help businesses and municipalities efficiently manage their waste streams and reduce their environmental impact.
Introduction to Food Waste Processing Equipment
Waste de-packaging equipment is a vital component in modern waste management processes. It allows for the separation of food and organic pulp from packaging materials such as plastic, paper, and metals. This equipment is designed to handle various types of packaging trash, including cans, bottles, tetra packs, and plastic containers.
Benefits of Food Waste Processing Equipment
Diversion of Rubbish from Landfills
Waste processing and depackaging equipment helps divert rubbish from landfills, which is crucial in reducing greenhouse gas emissions.
When organic pulp is sent to a landfill, it decomposes and produces methane, a potent greenhouse gas that contributes to climate change. By separating the organic pulp from packaging materials, waste de-packaging equipment ensures that the organic soup can be processed separately through composting or anaerobic digestion, reducing the amount of methane produced.
Reduction in Contamination
Waste de-packaging equipment helps to reduce contamination in the garbage stream. Packaging materials such as plastic and glass can contaminate organic pulp and reduce the quality of compost or biogas produced from anaerobic digestion. By separating the packaging from the organic trash bins, waste de-packaging equipment ensures that the organic trash is of higher quality and can be used in various applications such as composting, animal feed, or biogas production.
Cost Savings
Waste de-packaging equipment can help businesses and municipalities save money by reducing the amount of rubbish sent to landfills. With the increasing cost of landfill fees and the implementation of regulations such as landfill bans, diverting rubbish from landfills can lead to significant cost savings.
In addition, waste de-packaging equipment can help generate revenue by producing high-quality compost or biogas that can be sold to farmers or energy companies.
Types of Discarded Food Processing Equipment
Screw Presses
Screw presses use a rotating screw to compress and separate packaging materials from organic junk. The screw press crushes the packaging materials and extracts the organic material, which is then ready for further processing.
Trommels
Trommels are machines that are very often used in garbage processing and treatment facilities to screen and separate trashed materials based on their size and shape. These machines consist of a rotating cylindrical drum with perforated screens that allow smaller materials to fall through while larger materials are retained and conveyed out of the machine. Trommels are designed to handle a wide variety of junked materials, including municipal solid refuse, construction and demolition rubble, and industrial junk.
One of the key benefits of using trommels in trash processing is their ability to efficiently separate garbage materials based on their size and shape. This is particularly useful in separating out smaller materials, such as glass, plastic, and metal, from larger bulky items like furniture and appliances. This separation allows for more efficient and effective downstream processing, such as sorting and recycling.
Trommels can also be used in combination with other machines, such as magnetic and eddy current separators, to further refine the separation process and recover valuable materials from the rubbish stream. Additionally, some trommels can be equipped with water sprays to clean and wash the trashed materials as they pass through the drum, further enhancing the separation process.

Centrifuges
Centrifuges use centrifugal force to separate packaging materials from inedible organic pulp. The waste is fed into the centrifuge, which spins at high speeds, separating the packaging from the organic material. The organic material can then be further processed for composting or anaerobic digestion.
Shredders
Shredders use sharp blades to cut and separate packaging materials from organic junk. The trash is fed into the shredder, which cuts the packaging materials into small pieces and separates them from the organic material. The organic material can then be further processed for composting or anaerobic digestion. They are good at reducing the size and volume of garbage materials, making them easier to transport and handle.
Hammermills
A hammermill is a machine used for shredding and grinding various types of solid waste materials, such as paper, cardboard, wood, plastics, and metals, into smaller pieces. The machine consists of a rotating shaft with free-swinging hammers that repeatedly impact and break down the discarded materials as they pass through a series of screens. The resulting material is then further processed or recycled. Hammermills are often used in refuse processing and treatment facilities as they are efficient and effective at reducing the size and volume of waste materials, making them easier to transport and handle. They are also commonly used in the production of alternative fuels from junk materials.
Crushers
A crusher is a machine used for crushing and breaking down various types of solid garbage materials, such as concrete, bricks, stones, and asphalt, into smaller pieces. The machine operates by applying a compressive force to the trashed material, breaking it down into smaller chunks or particles that are easier to transport and handle. Crushers are commonly used in trash processing and treatment facilities but are only included here for completeness because they are rarely if ever used on municipal solid trash and are not suitable for wasted food processing.
Conclusion on How Food Waste Processing Equipment is Leading the Change
Overall, the use of processing and depackaging equipment is a valuable tool for the recycling industry. These machines take up much of the space inside the huge garbage processing and treatment facilities that are appearing in ever larger numbers around the globe.
These technologies are helping to improve the efficiency and effectiveness of trash separation and recovery processes. By separating materials based on their size and shape, they enable facilities to recover more valuable materials and reduce the volume of waste that ends up in landfills or incinerators, ultimately contributing to a more sustainable refuse management system.
The resulting cost savings and revenue-generating opportunities help governments to implement the concept of the “circular economy” which scientists and engineers say will be essential for the global community to avoid run-away climate change.
With the increasing focus on sustainability and reducing greenhouse gas emissions, depackaging equipment is a necessary investment for businesses and municipalities looking to streamline their waste management processes.
