BSI PAS 100

BSI PAS 100 is a nationally recognised standard for compost quality, developed by the British Standards Institution (BSI). It builds on the previous ‘Standards for Compost’ scheme to ensure composted materials are safe, reliable, and high-performing.

To achieve BSI PAS 100 Quality Protocol (QP) certification, compost must meet strict, independently verified standards. This includes controlled processing methods, such as an effective sanitisation stage, to ensure safety and consistency.

At Newbourne Farm Composting Ltd, all our products are fully BSI PAS 100 QP certified and regularly re-tested to maintain the highest quality.
