The cost-effectiveness of moulded pulp products is also a significant advantage. Although initial investment in machinery can range from $100,000 to over $1,000,000 depending on capacity and complexity, the operational costs are lower in the long term due to the use of abundant and cheap raw materials. Moreover, the production speed can reach up to several thousand units per hour, making it a viable solution for mass production.

Types of Moulded Pulp Products

Moulded pulp products can be broadly categorized into three types based on their use and manufacturing process:

Thick Wall: Used for packaging heavier items such as automotive parts and furniture. These products have a thickness of 4mm or more, offering high strength and cushioning. The lifespan of thick wall pulp products can extend several years under proper conditions, emphasizing durability.

Transfer Moulded: The most common type for egg cartons, food trays, and cup carriers. These products have a medium thickness of about 1-3mm and provide a balance between strength and aesthetic appeal. They are designed for single use but are fully biodegradable and compostable.

Thermoformed Pulp: This type uses heat and pressure to create finer and more detailed shapes, similar to plastic packaging. The thickness is usually less than 1mm, making it suitable for electronic packaging and other high-end applications. Thermoformed products offer enhanced quality and texture, with a surface smoothness that competes with plastic.

The material quality of moulded pulp products is directly linked to the raw materials used. High-quality, post-consumer recycled paper yields products with superior strength and sustainability credentials. The cost of raw materials can vary, but on average, recycled paper costs about $50 to $100 per ton, making it a cost-effective solution.

The environmental value of using moulded pulp products is immense, reducing reliance on fossil fuel-based plastics and lowering the carbon footprint of packaging. Moreover, the biodegradability of moulded pulp means that products typically break down in a compost90 days.

The Role of Moulded Pulp Products in Reducing Landfill Waste

Biodegradability and Recyclability

Moulded pulp products significantly contribute to environmental sustainability through their biodegradability and recyclability. Unlike plastic, which can take over 400 years to decompose, moulded pulp products degrade within 90 days when composted, returning nutrients back to the soil. This rapid decomposition rate means that even if they end up in landfills, they do not persist for centuries, reducing long-term environmental damage.
