Occupational Environment Monitoring at the Sawdust Pellet Manufacturing Plant

1. Overview of Sawdust Pellet Manufacturing Plant

a. What is a sawdust pellet manufacturing plant?

Manufacturing plant for sawdust pellets is a specialized industrial facility that processes sawdust into sawdust pellets. Sawdust is a type of waste generated from sawing and wood processing in the wood industry. Instead of consuming energy and resources to dispose of sawdust, the sawdust pellet manufacturing plant utilizes this waste and converts it into valuable pellets.

During the production process, sawdust is pressed and compacted into uniform pellets using pressure and natural or chemical binders. Sawdust pellets have good combustibility and can be used as an alternative fuel for traditional energy sources such as coal, oil, or gas. Additionally, sawdust pellets can also be used as raw material in brick production, wood chip manufacturing, or in the thermal power industry.

b. Production stages in a sawdust pellet manufacturing plant

The production stages in a sawdust pellet manufacturing plant may include the following steps:

• Receiving and storing sawdust: Sawdust is collected from the sawing or wood processing operations and transported to the plant. It is then stored in warehouses for the next stage.
• Processing and preparing raw materials: Sawdust is treated to remove impurities and unwanted materials. It is then mixed with natural or chemical binders to create a uniform mixture.
• Pellet pressing and compaction: The sawdust and binder mixture is fed into a pressing or compacting machine. Pressure is applied to form sawdust pellets, ensuring the desired density and durability.
• Drying: After pellets are formed, they may need to be dried to remove moisture and ensure the quality of the final product.
• Packing and storage: Finished sawdust pellets are packaged appropriately and prepared for storage or shipment to sales points or end customers.

c. Machinery used in a sawdust pellet manufacturing plant

In a sawdust pellet manufacturing plant, the following types of machinery may be used:

• Sawdust grinder: Used to finely grind sawdust into small particles and achieve the necessary fineness for pellet pressing.
• Pellet press machine: Used to compress the sawdust-binder mixture into pellets, applying pressure to achieve the desired density and durability.
• Drying machine: Used to remove moisture from the pellets after formation, improving quality and durability.
• Packing machine: Used to pack sawdust pellets into suitable packaging. This may include measuring, filling, bagging, or boxing as required.
• Quality control machines: Used to ensure that pellets meet quality standards and market requirements, including strength testers, density testers, moisture analyzers, and other inspection devices.
• Waste processing machinery: Used to handle waste and recycle by-products generated during production.

d. Occupational diseases workers may face in sawdust pellet manufacturing plants

Workers in sawdust pellet manufacturing plants may be exposed to potential environmental hazards that could cause occupational diseases. Common occupational diseases in this work environment include:

• Respiratory diseases: Long-term exposure to sawdust dust can cause respiratory problems such as pneumonia, asthma, sinusitis, and other respiratory illnesses.
• Skin diseases: Contact with sawdust or binders can cause skin irritation, dermatitis, itching, and other skin problems.
• Eye diseases: Exposure to sawdust dust can irritate and damage the eyes, causing infections, bacterial problems, eye pain, tearing, conjunctivitis, and dryness.
• Ear diseases: Noise from machinery may lead to hearing issues such as hearing loss, tinnitus, and other ear-related problems.
• Spinal and musculoskeletal disorders: Industrial work activities can place strain on the spine and muscles, causing back pain, neck pain, and joint problems.

To prevent occupational diseases, sawdust pellet manufacturing plants should implement health and safety measures, including providing personal protective equipment, ensuring safe work procedures, controlling dust and noise, maintaining good ventilation, training workers on occupational safety and health, and regularly monitoring and evaluating employees’ health.

e. Common types of sawdust pellets on the market

On the market, there are several types of sawdust pellets used for different purposes, including:

• Standard sawdust pellets: Produced from natural sawdust, usually from pine or other trees. They are typically cylindrical with varying diameters and lengths.
• Biological sawdust pellets: Made from biologically treated sawdust and used as a renewable, environmentally friendly fuel source.
• Heat-generating pellets: Designed to provide heat for heating systems and thermal houses, made from low-moisture, tightly compacted sawdust.
• Pellets for dryers and boilers: Used as primary material in dryers and boilers to produce heat efficiently, typically low-moisture and tightly pressed.
• Pellets for ovens and baking: Suitable for use in ovens and bread baking, with fast-burning properties that generate sufficient heat for cooking.
• Pellets for livestock: Some pellets are used in animal husbandry, providing warmth and odor absorption for animals such as chickens, pigs, or horses.

2. Overview of occupational environment monitoring services

a. What is occupational environment monitoring in sawdust pellet manufacturing plants?

Occupational environment monitoring (or workplace environmental measurement) in sawdust pellet manufacturing plants involves collecting, evaluating, and analyzing measured indicators of workplace environmental factors to implement timely mitigation measures, minimize environmental harm to workers’ health, and prevent occupational diseases. Occupational environment monitoring is a mandatory requirement for sawdust pellet manufacturing plants.

Monitoring plays a vital role in caring for, protecting, and enhancing workers’ health, as workers are the primary human resource that directly generates profit for the enterprise. Workers regularly exposed to risks or occupational hazards beyond allowable standards may suffer health impacts and occupational diseases.
