How to Choose a Shredder for Green Waste Processing

How to Choose the Right JENZ Shredder for Green Waste Processing

Choosing the right green waste shredder is about more than simply comparing machine sizes and headline throughput figures. The type of material you process, the volume you handle, your required output and how the machine fits into your wider operation all play an important role.

For businesses processing green waste, woody material, branches, roots, forestry residues or biomass, JENZ shredders provide a versatile solution designed for demanding professional applications.

CRJ Services is the UK and Ireland dealer for JENZ, supporting customers with machine sales, hire, parts, servicing and technical support. This means operators can get advice not only on which machine to choose, but also on how it can work effectively within their existing processing operation.

What is a JENZ shredder used for?

JENZ shredders are designed to process a wide range of organic and woody materials, making them suitable for applications across the waste management, recycling, forestry and biomass industries.

Depending on the machine and application, materials can include:

• Green waste
• Branches and tree trimmings
• Woody garden waste
• Roots and root wood
• Forestry residues
• Bark
• Wood waste
• Biomass feedstock

One of the key advantages of using a professional shredder is its ability to process mixed and variable material streams efficiently.

However, not every green waste operation has the same requirements. Choosing the right JENZ shredder starts with understanding exactly what you need to process.

1. What type of green waste are you processing?

The composition of your material should be one of the first considerations when selecting a shredder.

Green waste can range from relatively light garden and hedge trimmings to much heavier material containing large branches, roots and woody sections.

For example, an operation processing predominantly soft green waste may have very different requirements to one handling large volumes of woody arboricultural waste.

When discussing your requirements with a machinery specialist, consider:

• What percentage of the material is woody?
• What is the maximum material size?
• Are roots or root wood included?
• How consistent is the incoming material?
• Is contamination present?
• Does the material contain soil or other unwanted material?

Providing an accurate picture of the material allows the appropriate JENZ shredder configuration to be considered rather than simply choosing a machine based on its maximum capacity.

2. How much material do you need to process?

Throughput is naturally an important consideration when investing in a commercial green waste shredder.

However, the highest possible tonnes-per-hour figure isn’t necessarily the most important specification.

Consider how much material you actually need to process:

• Per hour
• Per day
• Per week
• During seasonal peaks
• Across the lifetime of the machine

The amount and consistency of material available will influence the size and specification of the shredder required.

A machine that is undersized for the application could become a bottleneck, while a machine significantly larger than necessary may not provide the best return on investment.

The objective should be to select a JENZ shredder that provides the right level of processing capacity for your operation.

3. What do you want the shredded material to be used for?

The required end product should also influence your choice of shredder.

Green waste may be processed for a variety of applications, including:

Composting
Shredding can help reduce the size of organic material before it enters a composting process.

Biomass
Woody waste and forestry residues can be processed into a more manageable feedstock for biomass applications.

Further screening
Shredded material can be passed through a trommel or other screening equipment to separate different fractions.

Mulch and landscaping
Depending on the material and required specification, processed green waste can be used in landscaping applications.

This is why it is important to consider the complete processing chain, rather than viewing the shredder as a standalone machine.

4. Do you need a mobile green waste shredder?

Mobility can be a major consideration for businesses processing green waste at multiple locations.

A mobile JENZ shredder can allow operators to take processing equipment closer to where material is generated, reducing unnecessary transportation of bulky, unprocessed waste.

This can be particularly valuable for:

• Arboricultural contractors
• Forestry businesses
• Waste management companies
• Local authorities
• Recycling operations
• Biomass processors
• Contractors working across multiple sites

Processing material closer to its source can potentially reduce handling and transportation requirements, while allowing businesses to make better use of their machinery.

The right solution will depend on your site, material flow and how frequently the machine needs to be moved.

5. Consider the complete processing system

A shredder is rarely the only machine involved in a professional green waste processing operation.

Depending on the application, the process could involve:

Material collection → Feeding → JENZ shredding → Screening → Stockpiling → Further processing or end use

This means the capacity of the shredder should be considered alongside the equipment around it.

For example, there is little benefit in having a shredder capable of processing significantly more material than the screening equipment can handle.

Likewise, the way material is fed into the shredder can have a significant effect on real-world productivity.

Looking at the whole processing system can help identify potential bottlenecks and ensure equipment works together effectively.

6. Don’t choose a shredder based on throughput alone

Manufacturers provide throughput figures to help operators compare machinery, but actual performance depends on the application.

Factors that can affect the output of a JENZ shredder include:

• Material type
• Material density
• Moisture content
• Feed size
• Material consistency
• Contamination
• Desired output
• Feeding method
• Operator experience
• Machine configuration

For this reason, a machine’s headline maximum throughput shouldn’t be the only figure considered when comparing green waste shredders.

The more useful question is:

How will this particular JENZ shredder perform on my material, in my operation and at my required output?

This is where application-specific advice can make a significant difference.

7. Buy or hire a JENZ shredder?

For some businesses, purchasing a shredder is the obvious long-term solution. For others, hiring a JENZ shredder can provide greater flexibility.

Buying a JENZ shredder

Purchasing may be suitable if you:

• Process green waste consistently
• Have a long-term requirement for shredding capacity
• Want to own your processing equipment
• Have predictable material volumes
• Want to integrate the shredder into an established processing operation

Hiring a JENZ shredder

Hiring can be particularly useful when you:

• Have seasonal increases in green waste
• Need additional processing capacity
• Have a short-term contract
• Are undertaking a specific project
• Want to trial a machine before purchasing
• Need flexibility while assessing future processing requirements

For some operators, hiring also provides an opportunity to see how a JENZ shredder performs on their own material before making a longer-term investment.

CRJ Services provides JENZ machinery for both hire and purchase, helping customers find an option that fits their operational requirements.

8. Think about support after the machine arrives

Selecting the right shredder is only the beginning.

What is the best JENZ shredder for green waste?

There isn’t one JENZ shredder that is right for every green waste application.

The best machine depends on factors including:

• Material: What are you processing and how variable is it?
• Volume: How many tonnes do you need to process?
• Output: What does the finished material need to look like?
• Mobility: Does the machine need to move between sites?
• Application: Is the material destined for composting, biomass, screening or another use?
• Operation: How frequently will the machine be used?

These factors should be considered together when selecting the appropriate JENZ equipment.
