European policies are advocating a transition toward circular bio-economy, an economy aiming at reducing the dependence from fossil-based resources, limiting greenhouse gas emissions and environmental impacts. The aim of this paper is to assess the potential for circularity for bio-waste and related by-products, to highlight the role of compost and vermicompost in the circular bioeconomy and their use in the agricultural sector. Three different substrates were tested in the soilless cultivation of Salvia officinalis, a Mediterranean nutraceutical and healthy plant: vermicompost (40%), compost (40%) and peat (100%). The average values of the main biometric parameters were calculated and compared. Compost and vermicompost can be considered as sustainable peat alternative growing substrates.
Keywords: Sustainable bio-waste management, nutraceutical and healthy plants, circular bioeconomy, sustainable peat alternative growing media, compost, vermicompost.
