ASTM D7831 Organic Fertilizer Recovery from Waste
The ASTM D7831 standard provides a method to recover organic fertilizer from waste materials, specifically targeting the recovery and quantification of nitrogen (N), phosphorus (P), potassium (K) inorganic fertilizers. This test is essential for waste management, recycling, and composting industries as it ensures that valuable nutrients are not lost during the decomposition process but can be recovered and reused.
The ASTM D7831 method involves a series of steps including sample preparation, digestion using strong acids, and subsequent analysis by various instrumental techniques such as inductively coupled plasma mass spectrometry (ICP-MS) or atomic absorption spectroscopy (AAS). The test measures the recoverable nitrogen, phosphorus, and potassium content from organic waste.
This service is critical for companies engaged in waste management, recycling, and composting. It helps them comply with environmental regulations while optimizing resource recovery processes. By accurately quantifying the nutrients available in waste streams, organizations can make informed decisions about how to best utilize these resources.
| Key Parameters | Description |
|---|---|
| Nitrogen (N) | Total nitrogen content which includes both organic and inorganic forms. |
| Phosphorus (P) | Inorganic phosphorus present in the waste stream. |
| Potassium (K) | Inorganic potassium found in the compost or waste material. |
The ASTM D7831 method ensures that all recoverable nutrients are accounted for, providing a comprehensive view of the nutrient content available for recovery. This information is crucial for optimizing fertilizer production processes and ensuring compliance with environmental standards.
For quality managers and R&D engineers involved in waste management and recycling projects, this service offers valuable insights into the potential value of waste streams. By understanding the precise composition of nutrients present in organic waste, they can design more efficient systems to recover these resources.
- Accurate nutrient recovery leads to better fertilizer production processes.
- Compliance with environmental regulations is simplified through precise quantification.
- Optimization of resource use within the industry enhances sustainability practices.
The ASTM D7831 method is widely recognized and used in laboratories around the world, ensuring consistent results across different testing facilities. This standardization is critical for maintaining confidence in the accuracy and reliability of nutrient recovery data.
For procurement officers seeking to source high-quality compostable waste materials, this service provides a reliable means of evaluating the potential value of incoming materials. By knowing the exact composition of nutrients present, they can make more informed purchasing decisions that align with their sustainability goals.
| Acceptance Criteria | Description |
|---|---|
| Nitrogen (N) | Average nitrogen content should be within the range of 0.5% to 1.2% for typical compostable waste. |
| Phosphorus (P) | Total phosphorus content must not exceed 0.4% in most cases. |
| Potassium (K) | Typical potassium levels range between 0.3% and 0.6% for organic waste materials. |
In conclusion, the ASTM D7831 Organic Fertilizer Recovery from Waste service is a vital tool in the waste management industry. It provides valuable insights into the nutrient content of organic waste streams, enabling more sustainable and efficient resource recovery processes.
