Compost and Digestate Testing

Contact us

Eurofins Food Testing UK Ltd. and Eurofins Agro Testing UK Ltd. offer ISO 17025-accredited testing services to support compliance with PAS 100, PAS 110, and the Animal By-Products Regulation (ABPR).

These standards support the safe reuse of organic materials across agriculture, landscaping, horticulture, and environmental applications.

 

What is PAS 100?

PAS 100 is the UK’s quality standard for compost. It ensures composted materials are

  • Safe for use in agriculture and horticulture

  • Consistent in composition

  • Free from unacceptable levels of contaminants and pathogens

  • Testing includes assessments for stability, maturity, microbiology, and physical contaminants

What is PAS 110?

PAS 110 is the UK's quality standard for anaerobic digestate, confirming the material is

  • Nutrient-rich and stable

  • Suitable for safe reuse

  • Compliant with end-of-waste criteria

  • Parameters include volatile solids, hygiene indicators, plant response, and physical contaminant levels

ABPR compliance for compost and digestate

If your compost or digestate includes animal by-products (ABPs), testing must also comply with Retained Regulation (EC) No 1069/2009. Depending on the material’s origin and intended use, approval from the Animal and Plant Health Agency (APHA) may be required.

Our testing services help ensure compliance with both PAS standards and the ABPR, supporting product quality, regulatory approval and safe application.
