“…Compost, which can be used as a soil improver, organic fertilizer and growing substrate, according to Italian Legislative Decree 75/2010, has not to exceed limit values of human and animal indicator pathogens, as well as potentially toxic elements (heavy metals), aerobic biological activity, physical contaminants (impurities) and weed seeds. Compost tends to have an alkaline pH (7)(8)(9), which can affect the availability of nutrients. The spreading of compost, that is a stable and pollutant free material, also contributes to carbon sequestration, as its organic matter is incorporated into the soil.…”

The aim of this work is to assess the usefulness of biowaste deriving from Circular Bioeconomy (CBE) processes (i.e., vermicompost, compost and digestate), as growing substrates for the partial or total replacement of peat, by measuring the vegetation biometric parameters of sage (Salvia officinalis L.)—leaf area; Soil Plant Analysis Development (SPAD) value (index of chlorophyll concentration); fresh and dry weight of leaves; stem weight; root length. The results showed that vermicompost positively influenced most of above parameters (+16.7% for leaf area, +7.3% for fresh leaf weight, +6.4% for dry leaf weight, +8.5% for fresh stem weight, +0.9% for dry stem weight, +16% for root length) and, therefore, can be used as a sustainable growing substrate, alternative to peat, for the sage soilless cultivation. Yet, the results of some biometric parameters are better with peat rather than with compost (−7.2% for SPAD value, −47.3% for fresh leaf weight, −46.8% for dry leaf weight, −32.9% for fresh stem weight, −39.1% for dry stem weight, −52.4% for fresh root weight, −56.6% for dry root weight) and digestate (−30.2% for fresh leaf weight, −33.6% for dry leaf weight, −23.9% for fresh stem weight, −27% for dry stem weight, −51.8% for fresh root weight, −34.4% for dry root weight, −16% for root length). Therefore, these results are interesting for potted plants in nursery activity, while the above differences must be verified also after the transplanting of the tested plants in open field. However, the use of all the above growing substrates alternative to peat allows the sustainable valorization of food industry by-products, plant biomass, animal manure and the Organic Fraction of Municipal Solid Waste (OFMSW).

“…Anaerobic Digestion (AD) is a process for converting organic wastes, for example, animal husbandry effluents; plant biomass [6], food industry by-products, sewage sludge and Organic Fraction of Municipal Solid Waste (OFMSW), including food waste, into biogas and digestate [4,[6][7][8][9][10][11][12][13][14][15].…”

“…This is a universally popular utilization method. During anaerobic digestion biogas and post-digestion liquid are produced, which can be used instead of mineral fertilizers [14][15][16][17][18]. Methane fermentation is a natural process -it is conducted in anaerobic conditions with the participation of microorganisms: acidogenic, acetogenic and methanogenic bacteria.…”

Abstract. Anaerobic decomposition of plant residues from which biogas is produced, generates very large amounts of digestate. Due to its physicochemical properties post-digestion liquid can be used as a fertilizer. Postdigestion liquid was used in the field cultivation of fodder alfalfa and winter wheat. The content of macroelements and the content of protein in the grains of winter wheat fertilized with digestate were on the same levels as in the grains of wheat fertilized with mineral fertilizers. The analysis showed a similar content of macroelements in alfalfa leaves fertilized both with post-digestion liquid and mineral fertilizers as well. Fertilizing fields with digestate brings destruction of possible pathogens. Digestate utilization as a fertilizer brings tangible benefits in agricultural production, but it is also a product, the application of which can reduce the negative effects of mineral fertilization and contribute to development of sustainable agriculture. The study has shown that digestate can be used as a fertilizer.

In Italy, the Organic Fraction of Municipal Solid Waste (OFMSW) is nowadays landfilled or processed through aerobic composting. The Italian towns currently support a high cost for OFMSW disposal and cause a high environmental impact, because of long distances travelled from towns to a few available landfills and fewer treatment places, as well as the used waste management methods. An interesting option for OFMSW is Anaerobic Digestion (AD), producing biogas and "digestate". In this survey a theoretical biogas plant was placed near a town of Sicily Region (Italy), centralised with reference to the area considered for producing OFMSW. The distances travelled every year to transport OFMSW from the nine towns considered to the nearest composting plant and the biogas one were calculated using QGIS software. Therefore, the energy balance was computed for each of the four considered scenarios. Within the implementation of Integrated Solid Waste Management (ISWM) method, AD resulted in an energy balance much higher than that of aerobic composting. In fact, differently from composting, AD can significantly contribute to energy recovery, while retaining the nutrients in the digestate produced and reducing Greenhouse Gas (GHG) emissions. The use of a rational network of towns for OFMSW collection and transportation results relevant, in terms of increased energy balance, only in the case of composting. Therefore, if AD would be implemented as OFMSW management method, by means of biogas plants, each of them placed in an area including some towns, e.g. that considered in this survey, it could highly reduce the cost and the environmental impact of waste disposal.
