The production of wood pellets has grown considerably in the last decades. Besides woody biomass, other feedstocks can be used for pellet production. Among these, miscanthus presents some advantages because, even if specifically cultivated, it requires low inputs such as fertilisers and pesticides and shows high biomass yield (up to 28 tons of dry matter ha−1 in Europe). Even if in the last years some studies evaluated the environmental impact of woody pellet production, there is no information about the environmental performances of miscanthus pellet production. In this study, the environmental impact of miscanthus pellet was evaluated using the Life Cycle Assessment approach with a cradle-to plant gate perspective. Primary data were collected in a small-medium size pelletizing plant located in Northern Italy where miscanthus is cultivated to be directly processed. The results highlight how the miscanthus pellet shows lower environmental impact compared to woody pellet, mainly due to the lower energy consumption during pelletizing. The possibility to pelletize the miscanthus biomass without any drying offsets the environmental impact related to the miscanthus cultivation for all the evaluated impact categories (except for Marine eutrophication). In detail, for global warming potential, 1 ton of miscanthus pellet shows an impact of 121.6 kg CO2 eq. (about 8% lower respect to woody pellet) while for the other evaluated impact categories the impact reduction ranges from 4 to 59%. Harvesting, which unlike the other field operations is carried out every year, is by far the main contributor to the impacts of the cultivation phase while electricity is the main contributor to the pelletizing phase.
In Italy, about 160 fatal accidents per year have occurred recently in agriculture, most of them involving agricultural machinery. The most frequent cause of fatal events is the tractor overturning. One of the opportunities to monitor the trend of agricultural tractors fatal overturning is a meticulous search for information on the numerous web portals, at national and local level. In fact, in their information purposes are also included the recording, practically in real time, of significant details about each fatal event, such as the place of the accident, the year, the month and the day of the week of occurring, the victim’s age, gender and nationality, etc. This article is describing the results of the monitoring of fatal tractor overturning accidents in the period of 2008–2019 in Italy. In the 12 years of the survey, 1414 fatal accidents were recorded, most of them occurring in the spring and summer months. The region with the highest cumulative number of fatal events was Tuscany (143). The majority (58.8%) of the victims were over 60, while 71.4% of accidents occurred during field work. Most (57.6%) of the tractors involved in the fatal events did not have rollover protective structures (ROPS), while 19.4% were equipped with a two-post foldable front roll-bar, which, however, was in the lowered position at the time of the accident. In most cases, the tractors involved were obsolete and in poor maintenance conditions, and did not comply with general and specific laws on work safety. To improve the situation, the introduction of the tractor training certificate for the drivers and the periodical inspection for tractors, as well as the issuing of significant financial supports to encourage the replacement of the old models with modern more safe models, are the most effective actions to be put into practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
