Compost stability test evaluation paper published
A paper has been published in the Journal 'Waste Management' on some work that was carried out to evaluate compost (and related industry) stability tests.
Five stability tests were evaluated on composts from ten in-vessel composting sites. Results were varied with strong correlations for some tests, with more variation in others, particularly with more active compost samples. The findings suggest that the dynamic respiration tests (ORG0020 and DR4) are best suited to deal with the wide range of compost stabilities found. The study also concluded that PAS100 accredited composts were generally found to be more stable than non-accredited composts.
