Intermediate Fraction (10–50 mm) Analysis
The intermediate fraction in waste management, particularly municipal solid waste (MSW), plays a crucial role in the overall waste characterization and recycling processes. This size range is significant because it encompasses materials that are neither too small to be easily captured nor too large to be of immediate interest for composting or landfills.
Accurate analysis of this fraction helps municipalities, recycling facilities, and waste management companies make informed decisions about the types of materials they can process. For instance, understanding the composition of the 10–50 mm size range allows for better sorting techniques to recover valuable resources like metals, plastics, and glass.
Our analysis service focuses on providing a comprehensive breakdown of this fraction, ensuring that stakeholders have all necessary data to optimize resource recovery processes. This includes identifying contaminants, determining material purity, and assessing the potential for further processing or recycling.
The process begins with rigorous sample preparation, where the waste is carefully sieved to isolate particles within the 10–50 mm size range. Following this, advanced analytical techniques such as X-ray fluorescence (XRF), infrared spectroscopy, and optical sorting are employed to characterize the material composition.
Our laboratory adheres strictly to international standards like ISO 14684-2:2019 for sample preparation and ASTM D7354 for particle size analysis. This ensures that our results are reliable and consistent with global best practices in waste management testing.
| Applied Standards | Description |
|---|---|
| ISO 14684-2:2019 | Sampling of municipal solid waste for chemical analysis, part 2 – Sampling and preparation of intermediate fractions. |
| ASTM D7354 | Determination of particle size distribution in municipal solid waste by sieving. |
| EN 12698 | Determination of the composition of municipal solid waste for recycling and composting. |
The results from this analysis are reported comprehensively, including detailed breakdowns by chemical composition, particle size distribution, and any identified contaminants. These insights help clients optimize their sorting processes, improve resource recovery rates, and minimize environmental impact.

Use Cases and Application Examples
The intermediate fraction (10–50 mm) is a critical component in waste management processes, particularly for recycling and composting operations. Here are some real-world applications of our analysis service:
- Sorting Optimization: By analyzing the composition of this fraction, facilities can optimize sorting techniques to better recover valuable materials.
- Contaminant Identification: Our detailed reports help identify contaminants that could negatively impact recycling processes or environmental health.
- Resource Recovery: Understanding the material content in this size range aids in designing more efficient resource recovery systems.
- Compliance Verification: Our analysis can be used to verify compliance with local and international waste management regulations.
An example of a successful application is when we conducted an analysis for a municipal recycling facility. The results helped them refine their sorting methods, leading to increased recycling rates and reduced landfill contributions.
