Sampling: What is the difference between continuous and discontinuous residuals?
As described in the Guide to FRMs, it is increasingly possible to get approval by obtaining a “Notice of Project” rather than a more cumbersome certificate of compliancy. In this case it is essential to deal with a company that benefits from ministerial accreditation.
Brome Mirabel Ingredients has been accredited to carry out sampling work by the Ministry of Sustainable Development, Environment, and Action against Climate Change (MSDEACC).
There are two main types of FRM production:
- Continuous production: This means that the FRM is generated in continuous fashion, i.e. a continuous, uninterrupted flow of materials during a certain period of time. If the fertilising residual results from such a continuous process, the sample must correspond to one day of production.
- Discontinuous production: This means that the FRM arises from one or more discontinuous activities and is stored in one or more piles. Discontinuous production is split up spatially or over time and can involve relatively small amounts. Sampling has to be representative of the volumes accumulated and the number of samples taken depends therefore on the size of the pile.
Similarly, different types of analysis are required:
The list of variables that need to be analysed differs according to the nature of the residual material and is given in Table 6.1 of the 2015 edition of the “Guide to Recycling Fertilising Residual Materials” . See previous reference.
- Analysis of inorganic variables : this involves mostly analysing metal content.
- Analysis of microbiological variables: this is the analysis of pathogens, usually the search for faecal coliforms and/or e-coli.
- Analysis of organic variables: this is carried out using metallic equipment in order to remove any materials that might affect the results of the analyses.
Whatever your product type or analysis needs may be, do not hesitate to contact us; we will be more than happy to advise you.
We are officially accredited for:
- Continuous FRM analyses (inorganic, organic and microbiological chemical analyses)
- Discontinuous FRM analyses (inorganic, organic and microbiological chemical analyses)
