A compactor is a machine used to reduce the volume of waste materials by compressing them. It is commonly used in landfills, construction sites, and recycling facilities to make waste management more efficient. By compacting materials, it helps save space and makes transportation easier. There are different types of compactors, including static compactors and vibratory compactors. Static compactors apply pressure to waste without movement, while vibratory compactors use vibrations to enhance the compression process. Both types play a crucial role in managing waste and improving the overall efficiency of waste disposal systems.
