The Autonomous Province of Bolzano's pilot project is entering its second stage. The first stage of the project focuses on finding ways to turn the semi-liquid digestate from the Lana biogas plant into valuable, high-quality compost products. This compost can be used as a soil improver and organic fertiliser for various agricultural and landscaping applications within the Autonomous Province of Bolzano.
The first phase of post-composting of digestate mixed with green waste has been successfully completed. On 2 February, the six compost piles of co-composted digestate (from the Lana biogas plant) and structuring material were screened. Over 12 weeks, the solids, interstitial gases and emissions were monitored. The final samples are now in the laboratory and the results will be discussed with project partners at BOKU Vienna, Vlaco and ECN next month. In the second trial additional waste streams from the local fruit and beverage industries will be used together with the digestate for post-composting.
