The brick industry is currently facing a shortage of natural resources. Despite this, the demand for construction bricks is progressively increasing. Alternative materials, such as dredged sediments and solid organic waste, have been recently proposed as options to replace natural clay in brick manufacturing. Potential exploitation of dredged sediments in clay bricks is evaluated in this study. The chemical composition of the mixtures and the opto-thermal properties of brick samples, which differed for the dredged sediment content (from 10% to 50% of the clay weight), were investigated. Chemical analyses detected lower concentrations of heavy metals in bricks incorporating dredged sediments (DS). Negligible variations in thermal conductivity, thermal diffusivity, and specific heat were observed by increasing the amount of DS in the mixture. In particular, the thermal conductivity values ranged between 0.45 ± 0.03 W m−1 K−1 (DS-50) and 0.50 ± 0.03 W m−1 K−1 (DS-30). Conversely, the color shift value and spectral reflectance in the infrared field were found directly proportional to the concentration of DS. Using dredged sediments as building material demonstrated to be a solution to the problem of their disposal and the scarcity of raw materials, reducing the global warming score by up to 2.8%.

Wine production is a key sector for the Italian economy, representing 13 billion euros per year. The proportion of the market raises concerns about improving the production technology at low cost, safe practices, and low environmental impacts. The recurrent life cycle assessment performed does not report on the impacts of frost protection. This study presents the potential environmental impact of a novel late frost protection technique for vineyards that is currently under development. It consists of an organic coating made of sugar and straw to prevent vine damage due to frosts in vineyards in the coldest hours of late winter and early spring. From previous research at the University of Perugia (Italy), the technique has proven to be an effective protection method for vine shoots. Currently, the yields are protected by highly energy-demanding methods. For this study, we simulated two different scenarios of frosting protection so we could point out possible hotspots for the field application of the novel method and compare it to a technique usually employed in central Italy. Under the Centrum voor Milieukunde Leiden (CML) method, the cotton candy technique is estimated at 316 kg CO2 equivalent emissions for hectare. Employing the organic sugar-coating means avoiding 69,375 kg of CO2 eq. compared to the traditional technique of oak wood-burning into the vineyard. Preliminary cost analysis demonstrated the economic viability of implementing the organic coating.

Green roofs are a recurrent solution for improving environmental quality in buildings. Such systems can, among other things, reduce the urban heat island effect, improve indoor thermal comfort and visual quality, and reduce energy consumption in buildings, therefore promoting human comfort. This work presents the winter monitoring of a light-weight green roof assembly with the potential to be implemented in extensive urban areas. The green roof monitoring was compared to those of previous bituminous and cool-coating applications. Results show that the system was able to decrease heat losses maintaining a positive energy flow from solar radiation gains and a more constant indoor temperature. In a well-insulated construction, the impact during the cold season was discreet. However, compared to the reference building, a slightly lower indoor air temperature (about 1
