What is a Trash Compactor?
A trash compactor is an electrical or mechanical appliance designed to compress and reduce the volume of waste. Here are some key facts about trash compactors:
- Work by applying intense pressure to trash, reducing volume by up to 75%
- Allow more trash to fit into standard waste receptacles and bags
- Come in free-standing and under-counter models for residential and commercial use
- Require special heavy-duty trash bags to handle compressed waste
- Reduce number of trash bags required for collection
- Decrease trash storage space needed and trips to dump waste
- Require electricity or battery power to operate the compression mechanism
- Help limit overfilling of waste containers
- Are more eco-friendly by optimizing landfill space
Trash compactors provide an efficient way to minimize waste volume before collection. They can reduce waste hauling needs for households and businesses.
What is a Garbage Disposal?
A garbage disposal is an electrical appliance that grinds up food scraps into tiny particles that can flush down the drain. Here are some key facts about garbage disposals:
- Designed to shred food waste from the kitchen into tiny pieces
- Use fast-spinning blades and motors to pulverize scraps
- Are installed under the kitchen sink and connect to the drain line
- Can handle most food items besides bones, grease, and fibrous veggies
- Require a constant flow of cold water when running to flush particles down
- Help prevent clogged drains by processing food debris
- Reduce amount of food waste sent to landfills and methane emissions
- Require electricity and proper installation for operation
- Can support a more sustainable way to handle food waste
Garbage disposals offer an efficient method for eliminating food waste within the home. They divert scraps from landfills and waste containers.
Major Differences
While trash compactors and garbage disposals both deal with waste management, there are some notable differences between the two appliances:
| Trash Compactors | Garbage Disposals |
|---|---|
| Compress all types of trash including food waste | Only grind up food scraps and waste |
| Reduce volume of waste for less frequent emptying | Eliminate food waste by sending it down the drain |
| Require special bags to handle compressed trash | Require a properly installed unit under the sink |
| Help optimize landfill space | Help divert food waste from landfills |
| Can minimize hauling needs for collection | Can increase grey water production |
While both appliances aim to optimize waste management, compactors condense all trash types and disposals only grind food. Compactors reduce waste volume for storage and collection, while disposals eliminate food waste via the sewer system.
Working Mechanism
Trash compactors and garbage disposals also differ significantly in their working mechanisms:
Trash Compactor Mechanism
- Uses a hydraulically or electrically powered pressing plate
- Plate applies intense pressure against the trash to compress it
- Trash is squeezed and condensed through powerful compacting force
- Pressure can be over 4,000 psi depending on the model
- Start button activates the pressing plate to initiate compaction
- Compressing cycle runs until maximum pressure is reached
- Compacted trash has 75% less volume on average
Garbage Disposal Mechanism
- Uses a high-speed electric motor spinning at 1,700+ rpm
- Motor powers metal turntable at bottom called a shredder plate
- Turntable has raised blades that pulverize food waste
- Food scraps are shredded by centripetal grinding action
- Spinning shredder and blades create particles small enough to flush
- Water flow prevents clogged drains and aids particle flushing
- Food waste flushed to sewers, wastewater treatment plants
Compactors reduce trash volume through strong compressive force, while disposals use fast grinding blades that shred and drain food waste.
