There is a need to find a solution to solve the problem of increasing agricultural practices which can lower the pressure on soil. Application of compost or biochar to the soil is proved to be a suitable solution to counteract this problem. Mixed application of these two products is even more sustainable environmental solution due to its effectiveness in the long-term carbon preservation. The biochar can be produced through gasification of municipal waste as a method for renewable energy production. This makes a new market for the unused biomass which is currently incinerated or landfilled. This paper summarizes the technical and economic aspect of system innovation toward utilizing organic and green waste for composting and energy production via gasification and application of the products (compost and biochar) for soil amendment, considering the case of Ravenna city in Italy. The municipal statistic data on waste management were used for this purpose. Gasification experiment of green waste for electricity production was performed in an open-top gasifier. The obtained results showed that the available waste in Ravenna could be used for production of large portion of energy consumption and at the same time provide biochar and compost mixture to be used in 700 hectare/y of the agricultural land in Ravenna. Moreover, the available methods and conditions in literature for mixing of biochar and compost were reviewed. The related European directives were also discussed. [ABSTRACT FROM AUTHOR]

Growth and vast usage in renewable energy implies better hourly and daily planning for reliable and constant renewable energy distribution. In this sense, the forecast of renewable energy becomes more and more important. In this work, we used the Weather Research and Forecasting Model (WRF) to forecast solar radiation. We run two forecast simulations with WRF and WRF-Solar model. Models have been running on daily basis to forecast solar radiation up to 48h with hourly outputs. In this paper we elaborated one summer month of 2017 with both model forecasts compared with ground measured data for solar irradiance at one location in Italy (lat 42°02.5' North; lon 12°18.4' East). Both models represents in good manner global irradiance with RMSE for a selected maximum of a daily range of about 13% while direct (25%) and diffuse (40%) solar radiation obtained by models differ from measured values.

This paper investigates the relationship between Indoor Environmental Quality index (IEQ): thermal comfort index and indoor temperature trend in moderate thermal environments, in buildings that belong to the Class A with reference to the Energy Performance of Building Directive (EPBD). The work consists of the measurement of IAQ and energy efficiency in a residential building located in centre-north of Italy, namely Ravenna. The results of the measurements, as well as the PMV-PPD indexes, are presented and commented. These indexes could be a criteria to test if EPBD labelling building could be coherent with EN 15251 [ABSTRACT FROM AUTHOR]
