Plastic granules

Sampling plastic granules in bulk has its own challenges and aspects that need to be considered. Here are some factors that should be considered when sampling plastic granules:

  1. Homogeneity: Plastic granules can vary in shape, size, color and chemical composition. Therefore, it is important to ensure that the sample taken represents this diversity. In some cases, it may be necessary to take several samples from different parts of the bulk material and combine them into one composite sample.
  2. Contamination: As with any sampling, it is important to avoid contamination. The sampling instruments should be clean and free of foreign materials to avoid contamination of the sample.
  3. Static: Plastic granules can generate static electricity, which can cause problems in the sampling process. The particles can stick to each other or to the sampling equipment. Appropriate equipment or methods may be required to overcome this problem.
  4. Physical properties: The physical properties of the granules, such as their fluidity, can affect sampling. This should be taken into account when choosing the sampling device.
  5. Environmental impact: Plastic granules are a type of microplastic that can have a significant environmental impact. Therefore, it is important to make sure that no granules are released into the environment during the sampling process.

When sampling plastic granules, it is important to ensure both the representativeness of the sample and safety and environmental responsibility. Appropriate training and equipment are essential, and sampling should always be carried out in accordance with applicable standards and best practices.
