Safety of Recycled Packaging

Smithers Pira will help you ensure that your recycled packaging is safe for use. We can perform studies to evaluate the effectiveness of recycling processes for both plastics and paper in the re-use of post-consumer waste for food packaging.

We can help you demonstrate safety of your recycled materials:
  • We carry out all work according to EU or FDA protocols.
  • Projects normally involve dosing virgin material with chemical surrogates and collecting the treated material in various points in the cleaning process.
  • Quantitative trace analysis of the surrogates in the cleaned material is then conducted and, if necessary, migration tests performed to establish the effectiveness of the process.
Support with EU Regulations

In the EU, recycling plastics for food contact applications is covered by Regulation (EC) No 282/2008. Part of compliance with this involves only using approved recycling processes. To approve a provess, it is necessary to submit a technical dossier to the ESFA. Part of this dossier involves determination of the decontamination efficiency of the recycling processes, often referred to as 'challenge testing' since it involves "challenging" the process with a plastic deliberately contaminated with surrogate contaminates.


How we can help:

- Smithers Pira can help you with this by preparing your contaminated feedstock, analysing it and then analysing the output from your process to determine the decontamination efficiency.

- We can also help you by writing this part of the dossier for you and providing advice on what you should include in the quality assurance system necessary to support future process users. 

Support with USA Regulations

In the USA, recyled materials are not covered by specific FDA Regulations, but need to comply with the relevant requirements of Chapter 21 of the Code of Federal Regulations.


How we can help:

To show that a recycling process is safe, we will use a challenge test in a similar fashion to that for the EU Regulations, but differing in the detail. 

Screening Tests

The screening tests aim to identify unknowns and provide a semi-quantitative analysis so that concentrations to food can be estimated by migration modelling. This approach has been applied to recycled plastics and irradiated plastics to good effect. 


How we can help:

Smithers Pira has developed a number of simple screening tests for evaluating the safety of Food Contact materials, whether recycled or materials containing NIAS.
