Compost specification details

BSI PAS 100 further details

A publicly available specification for compost materials has been prepared and published by the British Standards Institution (BSI PAS 100).

Compost standards

The BSI PAS 100 builds on the existing Composting Association standard. It will improve confidence in composted materials among end users, specifiers and blenders, and will help producers differentiate products that are safe, reliable and high performance.

The Composting Association has adopted BSI PAS 100 as the specification that composted materials must meet in order to achieve the independently verified Composting Association accreditation and use of TCA logo. Guidelines have been drafted to use as an easy tool when drawing up contracts for operation of large scale, licensed composting facilities.

Specifying Conformance to BSI PAS 100

These Guidelines have been drafted as an easy tool to be used when drawing up contracts for the operation of large scale, licensed composting facilities. They will help to properly refer to BSI PAS 100 in Local Authority Waste Management Contracts.
