Key points
- Balers make bales of a single material that can often be sold or recycled
- Compactors squash general or mixed waste into a container to cut the number of collections
- Many busy sites benefit from both — a baler for recyclables and a compactor for general waste
- The right choice depends on your waste mix, volumes, space and collection arrangements
Balers and compactors both reduce the volume of waste, but they do different jobs. Choosing the right one — or the right combination — can cut your waste costs and free up space on site.
What a baler does
A baler compresses a single type of material, such as cardboard, plastic film or plastic bottles, into dense, tied bales. Because the material is kept separate and clean, bales can often be collected by a merchant or reprocessor, and in some cases sold. Balers come in vertical models for lower volumes and smaller spaces, and horizontal models for high volumes and continuous feeding.
What a compactor does
A compactor compresses general or mixed waste into a container or skip. It doesn't make a saleable product, but packing more waste into each container means fewer collections — which can make a significant difference to transport costs. Static compactors are fixed in place and fed through a chute or hopper; portable compactors combine the compactor and container in one unit that is collected whole.
Questions to help you decide
- What's in your waste? Large volumes of clean cardboard, film or plastics point towards a baler. Mixed general waste points towards a compactor.
- How much do you produce? Volume decides the size of machine and whether vertical or horizontal (for balers) makes sense.
- How much space do you have? Think about the machine, the feed area, bale storage and vehicle access for collections.
- How are you collected? Talk to your waste contractor and your merchant about what they can take and how.
- Who will run it? Consider operator time and training, and how the machine fits into your site's routine.
Why many sites have both
On busy sites, a common setup is a baler for recyclables like cardboard and a compactor for whatever's left. Separating recyclables reduces the general waste going into the compactor, and good segregation often reduces overall waste costs.
Getting it right
The best choice depends on your site. We can look at your waste streams, volumes and layout and suggest a practical setup — whether that's a new machine, a refurbished one, or getting more from the equipment you already have.
Frequently asked questions
Can a compactor be used for cardboard?
It can, but compacting cardboard with general waste means losing its recycling value. If you produce a lot of clean cardboard, a baler usually makes more sense.
Do I need a vertical or horizontal baler?
Vertical balers suit lower volumes and smaller spaces and are loaded by hand. Horizontal balers suit high volumes and can be fed continuously, often by conveyor. Your weekly volume and available space are the main deciding factors.
This guide is general information to help you understand your equipment. Always follow your machine manufacturer's instructions and your site's safe systems of work, and isolate machinery before any inspection or maintenance.
