Actually, a clear definition of their status and quality is necessary to secure valorization opportunities for all of the treated organic matter. In this study, three digestion plants have been followed for one year. Raw, solid and liquid digestate were sampled and characterized five times along the year in order to state on their quality and to compare it to the existing standards for soil improvers and fertilisers. In a French context, digestates do not fulfil the product specifications of soil improvers or fertilisers.
