Humankind currently consumes more resources than our planet is able to generate. In our web survey, we investigated insects and earthworms, as a possible future food source. We targeted the survey to university students, as the possible future consumers and trendsetters of new food. A total of 3556 university students (18–29 years old) completed it. The aims of this study were to evaluate participants’ food preferences and their willingness to taste foods containing terrestrial invertebrates. Data were processed using Cronbach’s alfa to assess the reliability of each constructs. The food preferences showed pizza-focaccia and pasta at the highest rankings, followed by fruit and vegetables. Males have a higher preference for any kind of animal protein source. Gender influenced food preference and willingness to eat food with insect or earthworm ingredients. The results indicated that students were prone to consider novel food into the Italian diet and to familiarize with them in the future. Insects/earthworms were more accepted in salty snacks. Highlighting the essential amino-acids daily requirements of a snack with earthworm meal did not improve the willingness to taste it. Information and awareness of future global food demand can play a fundamental role in accepting new food.

Ammonia (NH₃), methane (CH₄), nitrous oxide (N₂O), and carbon dioxide (CO₂) emissions from livestock farms contribute to negative environmental impacts such as acidification and climate change. A significant part of these emissions is produced from the decomposition of slurry in livestock facilities, during storage and treatment phases. This research aimed at evaluating the effectiveness of the additive “SOP LAGOON” (made of agricultural gypsum processed with proprietary technology) on (i) NH₃ and Greenhouse Gas (GHG) emissions, (ii) slurry properties and N loss. Moreover, the Life Cycle Assessment (LCA) method was applied to assess the potential environmental impact associated with stored slurry treated with the additive. Six barrels were filled with 65 L of cattle slurry, of which three were used as a control while the additive was used in the other three. The results indicated that the use of the additive led to a reduction of total nitrogen, nitrates, and GHG emissions. LCA confirmed the higher environmental sustainability of the scenario with the additive for some environmental impact categories among which climate change. In conclusion, the additive has beneficial effects on both emissions and the environment, and the nitrogen present in the treated slurry could partially displace a mineral fertilizer, which can be considered an environmental credit.

Livestock activities, in particular swine farms, are sources of odorant compounds that cause conflicts with the neighboring population. Beside the effects on the neighborhood, excessive odor emission can cause discomfort to farm workers. In this context the APPROAch project, aims to test the application of two different air cleaning technologies (a wet acid scrubber and a dry filter) to reduce dust, ammonia and odors, in naturally ventilated pig facilities. The aim of the present study is to evaluate, in a pig farm, the odor removal efficiency of the two tested abatement technologies, based on air samples analyzed by dynamic olfactometry. Odor sampling was carried out at a pig facility involved in the project and brought to the lab within 30 h from sampling, as established by the European Standard EN 13725:2004. Odor concentration was evaluated by dynamic olfactometry using an Olfaktomat-n 6 (PRA-Odournet B.V.—Amsterdam, The Netherlands). The results show that the wet acid scrubber prototype presents an average odor removal efficiency of 16%, whereas dry filter has from limited to no effect. This efficiency could be considered as a good result for a prototype even if further analysis, with longer sampling periods are needed.
