What is PAS 100?

PAS 100 is an industry specification which can help end users distinguish compost products that are safe, reliable and high performance, from those that are not.

The standard covers the whole life cycle, from the production methods, through to quality control and laboratory testing. This ensures that the compost has been produced under best practice.


What are the benefits of PAS 100 certification?

PAS 100 certification allows composters to verify the consistent quality of their compost, thereby achieving ‘end of waste’ status. This reduces costs associated with waste handling controls and permits and opens new market opportunities.


How does it work?  

The standard requires the producer to implement a management system which ensures that compost is fit for purpose. This involves Hazard Analysis and Critical Control Point (HACCP) planning to identify and control hazards associated with adverse effects on the environment and on plant health.

WRM can develop a tailored PAS 100 management system including core documents such as the Quality Policy, Standard Operating Procedures and the HACCP Plan. WRM also conduct internal audits against the standard and provide support through the external certification process.
