2.5–3.0 T/H Cardboard Waste Fuel Pellets Machine in Chile

Raw Materials and Pellet Specifications

For this Chilean project, the client focused on sourcing locally abundant and readily available cardboard waste streams to ensure a consistent and cost-effective supply.

The primary raw materials included flattened cardboard boxes from packaging and distribution plants, post-consumer shipping boxes collected from urban recycling centers and retail stores, and industrial packaging scraps sourced directly from food and beverage manufacturers and other large-scale producers.

The cardboard waste undergoes a critical pre-processing stage to prepare it for pelletizing. The material is first shredded into small, uniform particles using industrial shredders.

These particles are then thoroughly mixed to achieve a consistent feedstock blend. Crucially, the moisture content of the mixture is carefully monitored and adjusted to an optimal level; this step is vital for ensuring the resulting pellets achieve maximum density, durability, and combustion efficiency during their end use as fuel.

The key technical specifications of the MZLH678 cardboard waste fuel pellets machines deployed in this project are detailed in the following table:

With two MZLH678 cardboard waste fuel pellets machine in Chile operating simultaneously, the facility achieves a combined production capacity of approximately 5 to 6 tons of fuel pellets per hour. This significant output level allows the client to consistently meet the substantial demand from industrial energy clients and participate meaningfully in the renewable energy supply chain.

The cardboard waste fuel pellets produced serve primarily as a high-grade renewable fuel source for several key applications. They are ideal for industrial heating, powering boilers in factories, bakeries, and food processing plants. They are also used for co-firing in biomass power stations, helping to reduce dependency on coal.

Furthermore, they contribute directly to various renewable energy projects, aiding in compliance with Chile’s national renewable energy targets. The pellets are specifically engineered for a high calorific value, low ash content, and uniform size to ensure efficient, clean, and reliable combustion in industrial settings.

Equipment Transportation and Installation

The logistics for delivering the MZLH678 cardboard waste fuel pellets machines from the manufacturer to the operational site in Chile were managed with precision. The machines were shipped from Qingdao Port in China to Valparaíso Port, Chile, one of the country’s primary and most important maritime hubs. Upon arrival and completion of customs formalities, the heavy equipment was securely loaded onto specialized trucks for the final overland transport to the client’s industrial facility in Santiago.

RICHI Machinery provided comprehensive, end-to-end support throughout this critical phase to ensure a seamless transition from delivery to production.

This support encompassed managing all necessary export documentation and facilitating smooth customs clearance in Chile, coordinating the entire sea transport logistics including insurance for the high-value cargo, providing professional on-site installation services and integrating the new pellet mills with the client's existing shredding and material handling equipment, conducting thorough machine commissioning and providing in-depth operator training focused on production efficiency and safety, and offering dedicated technical support during the initial trial production phase to troubleshoot any issues and optimize performance.

The client expressed particular appreciation for RICHI’s holistic service approach, emphasizing how this professional management significantly minimized potential installation delays and operational risks, allowing for a faster and more confident startup.

Equipment Features and Advantages

The MZLH678 cardboard waste fuel pellets machine was selected for its array of significant advantages that directly addressed the Chilean client's production needs and business objectives. Its standout features include high-capacity extrusion, capable of producing 2.5 to 3.0 tons per hour per unit, making it perfectly suitable for industrial-scale fuel production.

It offers versatile raw material handling, efficiently processing various types and thicknesses of cardboard waste. The machine ensures consistent pellet size and density, which is paramount for achieving high combustion efficiency in industrial applications.

Its robust and durable design is engineered to handle fibrous and thick cardboard continuously without necessitating frequent maintenance stops.

The standalone operational capability provides invaluable flexibility for batch processing, quality testing, and straightforward future expansion. Furthermore, its energy-efficient design optimizes electricity usage while maintaining high throughput, helping to control long-term operational costs.

These combined features empower the client to reliably produce high-quality, specification-compliant fuel pellets while maintaining tight control over both production quality and operational expenses.

Production Workflow

The production workflow implemented at the Santiago facility is meticulously organized to maximize efficiency, ensure product consistency, and maintain high quality standards. The process unfolds through six defined stages:

1. Collection and Sorting: Incoming cardboard waste is first segregated by type, thickness, and source to ensure a homogeneous feedstock and to remove any major contaminants.
2. Shredding: The sorted cardboard is fed into industrial shredders, which reduce the material into uniform, small particles ideal for smooth and consistent extrusion.
3. Mixing and Moisture Adjustment: The shredded particles are blended to achieve a uniform mixture. During this stage, the moisture content is precisely adjusted to the optimal level for pellet binding and final density.
4. Pelletizing: The conditioned feedstock is fed into the MZLH678 machines, where it is compressed under extreme pressure and extruded through the ring die to form dense, cylindrical fuel pellets.
5. Cooling and Screening: The hot, newly formed pellets are transferred to a cooling system (like a counter-flow cooler) to stabilize their temperature and hardness. They are then screened to remove fines and ensure a uniform, on-spec product size.
6. Packaging and Storage: The finished, cooled, and screened pellets are packaged into large bulk bags (big bags) or other industrial containers suitable for delivery to commercial clients, energy companies, and renewable energy projects.

This controlled and streamlined process is designed to guarantee that the final pellets meet stringent quality standards, resulting in a fuel product that burns efficiently and leaves minimal ash residue.

Market Potential and Pellet Application

The cardboard waste fuel pellets machine project in Chile strategically taps into a robust and growing market for renewable energy and sustainable industrial fuel. Chile’s industrial sector is increasingly seeking viable, cost-effective alternatives to coal and natural gas, a shift driven by both government incentives and tightening environmental regulations aimed at reducing carbon emissions.

By producing high-quality cardboard-based fuel pellets, the client achieves several key business and environmental objectives. They contribute to reduced fossil fuel dependency by providing a sustainable substitute for coal or wood in industrial boilers.

This allows them to build a strong eco-friendly brand, positioning themselves as a provider of sustainable energy solutions to environmentally conscious clients. The venture creates multiple revenue streams by selling pellets to a diverse client base including factories, energy companies, and dedicated renewable energy projects.

Most importantly, it delivers significant environmental benefits by diverting substantial volumes of cardboard waste from landfills and incineration, while simultaneously reducing the overall carbon footprint associated with industrial heating.

This multifaceted approach strategically positions the client as an innovative pioneer in Chile’s evolving sustainable fuel market, enabling them to generate profitable returns while fulfilling a clear and pressing environmental responsibility.
