1 T/H Fallen Leaf Pellet Machine in Lebanon

Why a Biomass Recovery Operator Is Looking at Fallen Leaves

In Lebanon, fallen leaves are generated through urban landscaping, garden maintenance and seasonal vegetation management. The quantity and composition depend on the location, tree species and collection period. In areas with deciduous trees, leaves can accumulate over a relatively short period, while olive-growing districts generate a separate stream of woody pruning residues during orchard maintenance.

The proposed customer is a small biomass recovery and agricultural waste processing operator. Its business already involves collecting and sorting plant residues from several sources. The aim is to make better use of selected dry material instead of handling every load as loose waste. However, the operator does not intend to pelletize all incoming leaves indiscriminately. Soil, stones, plastic litter, treated wood and other contaminants must be removed before the material enters the production process.

Fallen leaves are light and bulky. Their moisture content changes with rainfall, storage conditions and the time elapsed between collection and processing. Some loads contain mostly dry leaves, while others include wet foliage, grass clippings, twigs and soil. Feeding this mixed material directly into a pellet machine would make stable operation difficult.

The proposed solution is to establish a dedicated preparation route for the usable fraction. Fallen leaves remain a key component, while olive pruning residues and clean sawdust provide additional fibrous material. This gives the operator a more controlled feedstock than a leaf-only formulation and creates a practical basis for evaluating biomass pellet production.

A Blend Designed Around the Available Raw Materials

The project uses three material streams that may be available to an operator working with landscaping contractors and agricultural residue suppliers in Lebanon. The proposed formulation is expressed on a dry-matter basis. It is a starting point for trials, not a guaranteed production recipe.

The leaf fraction comes from screened landscaping collections, while olive pruning residues may be obtained from orchard maintenance. Sawdust should come from a traceable source and must not contain paint, preservatives, adhesives or other unsuitable contaminants.

The blend is intentionally not based on 100% fallen leaves. Leaf species and collection conditions can influence ash content, mineral composition, fiber structure and pellet durability. A woody fraction may improve the physical behavior of the mixture, but it does not automatically make the finished pellets suitable for every combustion system. Laboratory testing is still needed to establish the final product's fuel characteristics.

If trials show that the leaf fraction causes excessive ash, poor durability or unstable feeding, the formulation should be adjusted. The final proportions must be based on the actual raw materials and the specifications required by the intended buyer, rather than fixed solely to achieve a nominal output rate.

Preparing Fallen Leaves Before They Reach the Pellet Machine

Material preparation will determine much of the project's success. Freshly collected leaves should be inspected and separated from soil, stones, plastic litter and other foreign matter. Long twigs and branches should be removed from the leaf stream and processed separately with suitable size-reduction equipment before they are blended with the prepared leaves.

Dry leaves may require shredding or grinding to achieve a more uniform feed. Olive pruning branches generally need chipping first, followed by hammer milling or other suitable grinding equipment. For initial process planning, a particle size around 3 mm is a useful target for the prepared woody fraction. The final specification should be confirmed through trials because excessively long fibers can interfere with feeding, while unnecessarily fine grinding can increase power consumption and dust generation.

Moisture must be checked for each incoming material stream. Leaves collected after rain can hold considerably more water than material that has been stored under cover. Olive pruning residues may also vary in moisture according to their condition and storage period.

If the prepared material contains more than 20% moisture, a suitable drying stage is required before pelletizing. The proposed process should therefore retain access to a dryer or include one in the equipment plan if the operator's existing preparation system cannot meet the moisture requirement.

An initial moisture range of approximately 10–15% may be tested for the prepared blend. This is a starting point rather than a guaranteed optimum. Leaf-heavy mixtures can respond differently from ordinary wood materials, so moisture should be adjusted according to pellet formation, durability and feeding stability.

After drying and grinding, the three fractions should be mixed evenly. The material should not be sent directly from collection vehicles into the pellet machine. Consistent screening, particle size and moisture are essential if the operator wants to obtain repeatable output throughout the changing collection season.

MZLH420 Technical Specifications for the Project

One RICHI MZLH420 ring die biomass pellet mill machine is proposed for the initial installation. This model offers a reference capacity suitable for an operator seeking a more substantial output than a small pilot unit, while still retaining the option to expand the surrounding process equipment in stages.

The proposed 8 mm pellet falls within the model's stated diameter range. Its final length, density, durability and fines content should be established through production trials and aligned with the requirements of the intended fuel market.

The reference capacity of 1.0–1.2 T/H should not be interpreted as a guaranteed output for every leaf-and-wood mixture. Actual performance depends on moisture, leaf species, particle size, formulation, feeding conditions and the required pellet quality. A sample test is particularly important for this project because fallen leaves can differ substantially from conventional wood feedstock.

The anti-bridging feeder helps maintain material movement, while the forced feeder supports controlled delivery into the pelletizing chamber. These features are relevant when processing prepared plant materials with varying flow characteristics. Regular inspection, correct adjustment and routine maintenance remain necessary for dependable operation.

Why the Operator Is Starting with One Machine

The customer is not planning to replace the entire waste preparation operation. The proposed purchase adds a pelletizing stage to a workflow that already includes collection, sorting and material preparation. This makes a single-machine installation a reasonable first step for assessing the feasibility of the product.

Before committing to a complete automated biomass pellet production line, the operator needs to establish whether the available leaf-and-wood blend can produce pellets with acceptable durability and whether its ash characteristics meet the intended buyer's requirements. The trial should also reveal how much material is lost during screening and how consistently the machine can be supplied.

A staged investment gives the business room to adapt the formulation before adding more equipment. If the initial trials demonstrate stable production, the operator can evaluate a cooler, vibrating screen, conveyors and a packing machine according to the confirmed output rate.

RICHI Machinery supplies individual biomass pellet machines as well as complete pellet production line equipment. A customized process can be developed around suitable machinery that the customer already owns, reducing unnecessary duplication. The final arrangement should be based on the actual feedstock, the required product and the site's existing equipment.

Biomass Fuel Pellets and Other Potential Applications

The primary application in this proposed project is biomass fuel pellet production. However, the suitability of fallen-leaf pellets for combustion must be evaluated carefully. Leaf-rich pellets may have higher ash content than conventional wood pellets, and their performance depends on the plant species, contamination level and blend composition.

The finished product should therefore be assessed for moisture, ash content, durability and other relevant fuel properties. Its intended use must match the specifications of the receiving combustion equipment. A product suitable for one industrial biomass application may not meet the requirements of a different heating system.

Animal bedding pellets could be explored as a separate product if a suitable clean plant-based formulation can be developed and validated for the intended animal species. That would require separate testing of dust, physical stability, moisture behavior and material safety. The fuel formulation should not automatically be treated as suitable for animal bedding.

The MZLH420 configuration described here does not include a conditioning system for feed processing. It should be specified for appropriate non-feed applications such as biomass fuel or other suitable plant-based pellets, not for manufacturing animal feed.

Quality Checks That Matter for Leaf-Based Pellets

For this project, quality control starts before the raw material enters the machine. The operator should record the source and condition of each collection load, remove unsuitable material and check moisture after preparation. These steps help distinguish a problem caused by the feedstock from one caused by machine settings.

Finished pellets should be checked for diameter, length, fines and durability. If pellets break easily during cooling, screening or handling, the formulation, moisture level and particle-size distribution may need to be adjusted. The operator should also monitor whether changes in leaf species or seasonal conditions affect the results.

After pelletizing, cooling and screening may be needed before the product is packed. Cooling supports safe handling and helps stabilize the pellets, while screening removes fines and broken pieces. The appropriate packing arrangement depends on the expected storage period, delivery method and customer requirements.

Dust extraction and housekeeping are important throughout collection, grinding, feeding and pelletizing. Plant residues can generate airborne dust, particularly when dry material is handled at several stages. Suitable extraction arrangements, machine guarding and safe maintenance procedures should form part of the site plan.

RICHI Engineering Support and Future Expansion

For a fallen leaf pellet machine project, the equipment cannot be selected in isolation from the raw material preparation system. RICHI can review the proposed blend, target pellet diameter, expected operating hours and existing machinery before confirming the final configuration.

The technical review should include the condition of the incoming leaves, the size-reduction equipment available for woody residues, the drying capacity and the feeding arrangement. If the prepared material has an unusually high leaf fraction or variable moisture, the process may need to be adjusted before a reliable production target is established.

Customers can purchase an individual pellet machine or request a complete customized biomass pellet production line. Where existing machinery remains suitable, it can be incorporated into the process design. Additional equipment can be considered later if the project expands beyond the initial pelletizing stage.

The proposed project in Lebanon illustrates a practical starting point: recover selected fallen leaves, blend them with suitable woody residues, prepare the material consistently and test the resulting pellets before committing to larger-scale automation. The MZLH420 provides a defined equipment option, while final performance and product suitability remain dependent on the actual raw material.

Shipping the Equipment to Lebanon

The proposed sea-freight route is from Qingdao Port in China to the Port of Beirut in Lebanon. The final routing, shipping schedule, cargo dimensions and freight arrangements should be confirmed with the logistics provider before dispatch.

Before the equipment arrives, the customer should confirm the installation space, electrical supply, foundation requirements and maintenance access. The upstream preparation system should also be checked to ensure that it can provide material with a consistent particle size and moisture level.

Commissioning should focus on stable feeding, pellet formation and the agreed product specification. Recording the raw material blend, moisture, operating conditions and finished pellet quality will help the operator establish repeatable settings as the composition of seasonal leaf collections changes.

Discussing a Fallen Leaf Pellet Project with RICHI

The proposed fallen leaf pellet machine in Lebanon project uses one MZLH420 ring die biomass pellet machine, with a reference capacity of 1.0–1.2 T/H and a target pellet diameter of approximately 8 mm. The initial plan is to process a controlled blend of fallen leaves, olive pruning residues and clean sawdust into biomass pellets, subject to material testing.

The key to the project is not simply pressing leaves into pellets. It is selecting a suitable feedstock, controlling contamination, managing moisture and confirming that the finished product meets the intended application's requirements. A trial with representative material is the most useful way to establish realistic operating conditions.

RICHI can assist in reviewing the proposed raw materials, assessing the equipment configuration and determining whether the project should begin with a single pellet machine or be developed into a complete biomass pellet production line. Customers considering a similar installation can provide details of their feedstock, moisture content, target pellet diameter and expected output to support the equipment selection process.
