Briquetting, Baling, or Shredding?
Selecting the Right Waste Processing Machine for Your Factory
Every production line leaves something behind: metal chips from CNC machining, aluminum offcuts, sawdust, plastic, paper, and cardboard. Left loose, this material takes up floor space, slows down handling, and adds to labor and transport costs.
Three technologies deal with it: briquetting, baling, and shredding. They are not interchangeable. Each solves a different problem, so the right choice starts with your material and what you need to achieve.
Before choosing a machine, define the main problem you need to solve: reducing volume, recovering value from scrap, or preparing material for the next process.
Cuts large or bulky material into smaller pieces. It reduces size.
Uses a hydraulic ram to compress bulky material into large bales, which are then tied with wire or strap.
Uses high hydraulic pressure to compact loose, granular material into small, dense briquettes.
Simply put:
A briquetting press compacts loose metal chips and scrap under high pressure, forming solid, dense briquettes. It is the standard solution for chips produced by turning, milling, and drilling.
Loose chips are bulky and difficult to store and handle. A Briquetting Machine can reduce the storage space they need by 5:1 up to 20:1, depending on the material. This means significant space savings and lower transport costs for scrap haulers.
During compaction, the press also squeezes out the coolant and cutting oil trapped in the chips. The recovered coolant can be filtered and returned to your machining lines, cutting coolant purchases and reducing the volume of oily waste you need to dispose of.
Briquetting also adds value at the recycling stage. Dense, dry, uniform briquettes improve yield when the material is recycled. Results depend on the material, so chip type, chip length, and oil or moisture content should be checked before selecting a machine.
A baler compresses large, light, or springy material into bales that are easy to stack, move by forklift, and ship. Typical applications include:
Cardboard and paper
Plastic film, PET bottles, and containers
Light sheet-metal scrap and other bulky recyclable waste
For high-volume operations, a horizontal auto-tie Baling Press Machine compresses and ties bales automatically, keeping pace with continuous production and making waste recycling operations more efficient.
As a rule of thumb: if the material is bulky and light, bale it. If it is loose chips or fine scrap, briquette it.
Shredding does not compact material. A Shredder Machine breaks long metal scrap and turnings into smaller pieces that are easier to store, transport, and feed into the next process. It can handle carbon steel, stainless steel and other alloy steels, aluminum alloys, porous steel, and titanium.
Because it crushes material rather than striking or cutting it, a well-designed shredder uses less energy, causes less wear, runs quietly, and keeps operating costs low.
Shredding is often the first stage of a complete processing line, for example:
Shredding → Briquetting
Shredding → Sorting → Baling
Long, stringy turnings are difficult to compact as they are. Shredding them first gives a more consistent feed, so the briquetting press produces better briquettes and runs more efficiently.
You have loose metal chips or fine scrap that take up too much space, carry coolant, and need densifying before storage, transport, or recycling.
You have long turnings or bulky metal scrap that are too large or tangled to handle or to feed into another machine.
Many factories need more than one process. A combined line, such as a shredder feeding a briquetting press, often delivers better results than any single machine.
Match the machine to your factory's main challenge:
Specifications only tell part of the story. Review these four points first.
Rated force in tonnes is easy to compare, but it is not the whole picture. In briquetting, what actually compacts the material is the specific pressure on it, which depends on both press force and briquette diameter. Two machines with the same tonnage can produce very different results.
Hydraulic system design matters just as much. Pump and cylinder sizing, cycle time, oil cooling, and duty rating determine whether a machine can run reliably shift after shift. A correctly matched machine will outperform a larger one that is wrong for the material.
Briquetting compacts loose metal chips and scrap into dense briquettes, reducing storage volume by up to 20:1 and recovering coolant for reuse.
Baling compresses bulky material such as cardboard, paper, and plastic into tied bales.
Shredding breaks long and bulky metal scrap into smaller pieces for easier handling and downstream processing.
Used together, they can form a complete material-handling system.
Before investing in a Briquetting Machine, Baling Press Machine, or Shredder Machine, review your material type, daily volume, material size, and intended output. An experienced machinery specialist can help you match the right equipment to your factory.
The best machine depends on your material and process requirements. If you are unsure whether briquetting, baling, or shredding is right for your application, contact the B.P. Power Engineering team for expert advice from our hydraulic engineers.
We also offer material testing services. You can test your actual waste on our machines before purchasing, so you can see the results and choose with confidence.

Material Type and Properties
Identify the exact material: carbon steel, stainless or alloy steel, aluminum, titanium, or non-metal waste such as cardboard and plastic. Hardness, bulk density, particle size, and oil or moisture content all affect which machine works and how well it performs.
2. Daily Processing Volume
Measure your output in kilograms per hour or tonnages per shift, and allow for production growth. A machine sized only for today's volume can quickly become a bottleneck.
3. Feed Material Size
Size is the deciding factor when selecting a shredder, and it also affects compaction equipment. Long or tangled material may need shredding before it can be briquetted or baled.
4. End Use of the Processed Output
Define your goal: saving storage space, lowering transport costs, recovering coolant, improving recycling yield, or selling scrap. The end use determines the right output format, and therefore the right machine.
You have large volumes of cardboard, paper, plastic, or light scrap that need compressing into bales.
