Influence of greenhouse different coverings on chemical and physical risk factors
2005
Crop production in greenhouses needs the use of chemicals and requires high levels of temperature and relative humidity to assure the increasing of crop production. This can cause risks for the health of the operators, especially if they are not equipped with protection devices. The risks may also vary with the type and/or size and/or shape of the protected structures. In order to determine the influence of different coverings on type and amount of risks, chemical and physical risk factors were measured inside greenhouses with different cladding materials (glass panels and plastic films) after crop management. In these two different greenhouses typologies, that were similar for location and…
The evaluation of urban soils aimed at the sustainability of plants in public and private flowerbeds
2020
The authors report the survey of some flowerbeds located in the city of Palermo with the aim of assessing the sustainability of the plants and the interventions to be implemented, i.e. cutting or transfer of plants, to achieve a sustainable green. In the case in which it is possible to insert other plants in the flowerbeds, it is recommended to elaborate a project using programs that allow to have a preview of the spaces available for the new plants. This work is methodological and is aimed at creating a green that can achieve the functional objectives in relation to the site where it is located (sustainability in all aspects) and at low management costs with no or almost no irrigation prac…
Sustainable technologies for greenhouse systems
2020
The greenhouse cultivation system in European countries represents one of the most energy-intensive sectors in the agriculture and agro-industry sector. In this regard, renewable energies represent an innovative solution to reduce energy costs and environmental impacts. Both, the energy demands and the economic aspects are analyzed with regard to the main energy users, i.e.: heating and cooling systems, lighting and pumping for irrigation. This work considers the use of solar photovoltaic and thermal energy. The use of semi-closed greenhouses is also considered.
Investigating on the environmental sustainability of organic animal products? The case of organic eggs
2020
Abstract The organic farming of laying hens is experiencing a growing trend in Italy, following an increase in consumer demand for organic eggs. The present study aimed to investigate the environmental performance of organic egg production for the first time in the Italian context. To this end, the Life Cycle Assessment (LCA) of organic egg production in a farm rearing laying hens located in Northern Italy was performed. The analysis was carried out in a cradle to farm gate perspective, with 1 kg of eggs selected as functional unit. Primary data relating to animal performances and resources consumed was collected on site, and subsequently integrated with secondary data, including estimates …

A Novel System for Measuring Damaging Impacts on Table Olives
2015
The consumer today demands high quality products; fruit with defects or in poor condition generate dissatisfaction and a consequent reduction in consumption. In recent years, interesting systems have been used (i. e. "artificial fruit") in order to identify the cause of damage during mechanical harvesting and/or post-harvest operations. In this paper, the authors present a new system designed to measure the impacts received by table olives in the processing stages from harvesting to packaging. The device is an instrumented sphere designed and implemented by the Agricultural Mechanics Section of the Department of Agricultural and Forest Sciences, University of Palermo, Italy. It contains a t…

Valorisation of urban green areas for producing renewable energy and biochar as growing substrate of Sicilian aromatic and nutraceutical species in a…
2020
This work is aimed at evaluating the possible building up of a gasifier for the energy valorisation of residual biomass deriving from urban areas and their surroundings. The area and the volumes of supply and economic convenience have been determined by implementing a GIS-based geographic method to the localisation and quantification of non-uniform elements of plant biomass. The pyrolysis and gasification processes of the lignocellulosic biomass obtained from pruning and maintenance operations of the urban and ornamental green include the production of a residual amount of biochar. The biochar can be used in agriculture as a soil improver and a substrate alternative to peat in the sustainab…
Hydroseeding application on degraded slopes in the southern Mediterranean area (Sicily)
2013
Abstract. Hydroseeding is a technique increasingly used to establish vegetation on degraded areas in order to provide environmental protection. The objective of this article was to evaluate the effectiveness of four different hydroseeding methods (bonded fiber matrix hydroseeding, thick hydroseeding, reinforced hydroseeding plus water retention, and reinforced hydroseeding) on a degraded artificial slope in the southern Mediterranean area determining total vegetation cover, hydroseeding vegetation cover, hydroseeding success index (HSI), natural and hydroseeded vegetation height. The test area does not allow the use of any operating machinery for soil and vegetation management, and the only…
Biowaste in a circular bioeconomy in Mediterranean area: A case study of compost and vermicompost as growing substrates alternative to peat
2020
European policies are advocating a transition toward circular bio-economy, an economy aiming at reducing the dependence from fossil-based resources, limiting greenhouse gas emissions and environmental impacts. The aim of this paper is to assess the potential for circularity for bio-waste and related by-products, to highlight the role of compost and vermicompost in the circular bioeconomy and their use in the agricultural sector. Three different substrates were tested in the soilless cultivation of Salvia officinalis, a Mediterranean nutraceutical and healthy plant: vermicompost (40%), compost (40%) and peat (100%). The average values of the main biometric parameters were calculated and comp…
