Full textConsiderata la complessità globale, il sistema dei poteri pubblici richiede il supporto del sistema sociale. L’uomo, in quanto membro della collettività, è chiamato a cooperare con l’Amministrazione, così integrando la funzione pubblica con quella privata, in un rapporto di tipo sussidiario. E’ oramai tramontata l’idea di un uomo non “socialmente impegnato”, il suo ruolo è riconsiderato come funzionale a finalità di cooperazione, per contribuire al sistema comune. L’ambiente determina il rovesciamento della visione di proprietà, che muta da attiva in passiva. Non è più l’ambiente, considerato come un bene, ad appartenere all’uomo, ma è quest’ultimo ad appartenere al primo. Si assiste a un allargamento delle garanzie, mediante lo sviluppo del diritto positivo verso un modello di amministrazione pubblica orizzontale, dove il rapporto tra soggetti pubblici e privati è ispirato alle logiche della corceted decision, rinvigorendo la legittimazione del privato alla partecipazione al procedimento. La public partecipation diviene una condizione di effettività della decisione, che, ove mancante, determinerebbe l’invalidità della decisione stessa. La previsione di una decisione condivisa e partecipata fa sorgere in capo all’Amministrazione competente un insieme di doveri, corrispondenti ad altrettanti diritti per i consociati, la cui violazione può essere direttamente causa di vizio per la decisione. Rispetto alla decisione finale dell’Amministrazione Pubblica, non risulta semplice definire quale sia il limite che divide la discrezionalità dalla doverosità del potere amministrativo. Risulta fuori discussione come l’attività della P.A. devia tendere alla migliore attuazione del principio dello sviluppo sostenibile, con il vincolo della priorità nella considerazione degli interessi alla tutela dell’ambiente. I cambiamenti analizzati inducono a considerare come la superiorità del potere pubblico sia stata sostituita dall’effettività, capace di offrire un esisto positivo all’attività pubblica. L’analisi economica della bontà della partecipazione e della rappresentazione delle istanze della collettività interessata passa attraverso l’affermazione della soggettività del valore ambientale, indefinibile aprioristicamente. Un approccio di tipo precauzionale, seguendo l’onda dello sviluppo sostenibile, consente di superare i limiti e le forzature che un’analisi basata sui costi e sui benefici potrebbe comportare, così relegando a un ruolo marginale la tecnica autoritaria del “comand and control”. La partecipazione dialettica del privato allo svolgimento della funzione, oltre a essere un’occasione di completamento per l’istruttoria, consentendo la c.d. regulation by information, permette di superare il rischio del proliferarsi dei fenomeni cc. dd. NIMBY. Questi ultimi, oltre a essere un costo per l’intera collettività, rappresentano ,soprattutto, il malcontento delle popolazioni che effettivamente vedono mutare la proprio quotidianità, in funzione di scelte di insediamento, prese spesso da lontano e sull’errato presupposto che benefici di breve periodo siano il mezzo migliore e più congruo per giungere a qualunque risultato. L’espressione comunitaria del principio di precauzione rende possibile la c.d. opzione zero in mancanza di un pieno ed esaustivo corredo di prove e di test tecnico scientifici. La scelta di campo dell’Unione europea per una versione “debole” del principio di precauzione, al cospetto di costruzioni più “forti” proposte dal diritto internazionale, sembra essere stata messa da parte e rimpiazzata da una più plausibile percezione della sua elasticità, nella sua intrinseca flessibilità e che, pertanto, la sua apparente debolezza possa in realtà risolversi in un vero e proprio valore aggiunto, in una forma aggiuntiva che finisce con il costituirne il più rilevante tratto di identificazione e di qualificazione. L’evoluzione dell’ordinamento e il conseguente abbandono della netta contrapposizione tra pubblico e privato ha recepito istanze di legalità sostanziale non più soddisfabili mediante il richiamo al solo principio di legalità. Il mutamento dei parametri dell’azione amministrativa, non più semplicemente agganciata ai filtri dell’imparzialità e del buon andamento, ritenuti oramai non sufficienti, ha comportato la sostituzione del “primato dell’autorità” con il “primato del consenso”1. L’interesse pubblico viene oggi individuato non con la legge, ma in itinere, mediante l’attività istruttoria 2 , vero e proprio strumento di partecipazione, prescindendo dal quale risulterebbe difficile giustificare l’esercizio di ampie potestà discrezionali da parte della p.a. La chiave di volta di questo cambiamento culturale è tutta nella “Deliberative Democracy”, che può conferire legittimità, equità e correttezza a procedure complesse, così come affermato dalla nuova direttiva 2014/52/UE. L’ordinamento francese può essere considerato, da questo punto di vista, come un buon esempio. Mediante l’enquete publique si è infatti realizzata la valorizzazione del momento partecipativo, andando oltre quella che è la logica della maggioranza, compiendo un passo in avanti importante verso la piena valorizzazione e applicazione del principio democratico. Questo modello riconosce l’importanza della formazione di un’opinione pubblica attenta in tema di procedimenti ambientali, in grado di controllare, 1 F. Bassi, Autorità e consenso, in Riv. Trim. Dir.

Un’attività della P.A. priva dell’apporto del cittadino finirebbe per risultare carente delle necessarie giustificazioni giuridiche. mediante un accesso agevole alle relative informazioni, la portata dell’impatto ambientale, le prospettive e gli esiti connessi alla realizzazione di un progetto.

Full textThe aim of this research project is the study and development of new high-performance construction materials, namely geopolymers, more sustainable than those already widely on the market (such as Ordinary Portland Cement-OPC), obtained from the recovery of industrial waste materials, for an environmental protection and sustainable development. The exploitation of different kinds of clayey waste -halloysitic, kaolinitic and smectitic - from mining operations, as potential precursor of geopolymeric materials in the view of a circular economy of mines is the main goal of this study. The influence of the main experimental variables such as type of the aluminosilicate powder, curing condition and temperature, composition of activating solution and molar Si:Al cation ratios on the geopolymerization process were deepened to achieve the finest properties of the final products. The influence of the calcination temperature on the reactivity of the aluminosilicate powders and on the properties of the final products were investigated. The mix design of formulations started with the use of clays as received without any firing pre-treatment and it was continued with the use of calcined clays. The clays were thermally treated at the temperature of 400-650°C. Then, the addition of low percentages of reactive fillers, specifically a sand from a clay washing process, waste glass powder, and a commercial metakaolin (MK), into the mix design of waste clay-based materials was evaluated to improve the chemical-physical properties and the consolidation degree of the materials. In fact, these clays alone are often not sufficiently reactive to obtain chemically stable formulations with acceptable mechanical properties but require the addition of reactive fillers. The alkali activators used in the formulations are NaOH 8M and Na2SiO3. Samples were cured at room temperature, except for a particular set of samples made with untreated clay and cured in conditions of controlled temperatures and humidity. Samples obtained were characterized to evaluate the influence of synthesis parameters on the microstructure and chemical and mechanical resistance. The chemical stability was analysed with the pH and ionic conductivity of leachate water and weight loss. The comparison of setting times was evaluated with the Vicat needle test. The variations on the microstructure were observed with density, XRD and SEM analysis, and tested the mechanical performance with the compressive strength. From this study, good formulations of high-performance materials based on clayey waste, consolidated at room temperature during 24-48 h, with compressive strength of 20-30 MPa were obtained. Thermal and dilatometric characterizations were also carried out on the best formulations to assess their resistance to heating. In alignment with the Circular Economy approach, this research activity shows a possible route of valorisation for different typologies of mining waste materials widely available to create alternative binders with reduced environmental impact and good performances. Additionally, the room temperature consolidation via alkaline activation of low cost Na-bearing solutions is also proposed to keep costs in line with cheap building materials. Apart from the aqueous solution, the proposed technology has no-water consumption. It should also be noted that the proposed materials processing does not, in turn, generate waste, thus closing the loop of green economy circle with no-water and no-waste manufacturing proposal.

Full textThe activity of the PhD research focused on the study of thermophysical properties and performance of new refrigerants and their mixtures with low environmental impact. This study was carried out using three different experimental set-ups: the isochoric apparatus, the apparatus SLE and experimental refrigeration system operating with a cycle cascade. The isochoric apparatus allows to find the P-V-T points of a gas or of a mixture both in the biphasic region and in superheated steam. The use of two thermostatic bath with silicone oils with different viscosities allows to study a range of temperatures ranging from -50 ° C to 100 ° C. It was immediately studied the new refrigerant R1234yf, which has replaced R134a in the car air conditioning, due to its low GWP value, in line with the new European directives. Data weren’t present in the literature yet, so results were published and subsequently confirmed by other studies. We subsequently turned to the study of thermophysical properties of the mixture R1234yf-CO2, and then we tested the other isomer and the mixture R1234ze R1234ze-CO2. The results were always compared with data from Refprop, the equation of Wagner in the biphasic region and the state equation of Martin-Hou in the region of superheated steam. The charging system has undergone changes to decrease the uncertainty due to estimation of the lost mass, the weak point of isochoric apparatus. A vacuum system was created to recover and weigh the loss mass in stages, so you can replace the previous estimate with a certain degree. The plant has been repeatedly tested with known gases, in order to validate the tests performed. The apparatus SLE allows to determine the melting point of the refrigerant gases and their mixtures, which were very low, requiring the use of liquid nitrogen. First, we found the triple point of the following fluids: - four hydro-olefin 2,3,3,3-tetrafluoroprop-1-ene, R1234yf, trans-1, 3,3,3 tetrafluoropropene, R1234ze (E), 3,3,3-trifluoropropene, R1234zf, 1.2, 3,3,3-pentafluoropropene, R1225ye (Z); - Five derivatives of propane-eptafluoropropano 1,1,1,2,3,3,3, R227ea; 1,1,1,3,3,3- exafluoropropano R236fa, 1,1,2,3,3,3 - exafluoropropano R236ea, 1,1,2,2,3- Pentafluoropropane, R245ca, 1,1,1,3,3-Pentafluoropropane, R245fa; - Three derivatives of the methane fluorometano, R41, and the Difluoromethane, R32, and the trifluoromethane, R23; - The four derivatives of ethane pentafluoroethane R125, 1,1,1,2-Tetrafluoroethane, R134a, 1,1,1,-trifluoroethane, R143a, 1.1-difluoroethane, R152a; - Mixtures: R1234yf-CO2, N2O and CO2-R1234ze + R41. Regarding the latter, the results were adjusted, where necessary, by the method of Rossini and interpreted using the equation of Schröder. The system was optimized by eliminating the internal copper coil that wrapped the measuring cell and placing the liquid nitrogen directly in contact with the measuring cell, thus improving heat transfer and reducing consumption of nitrogen liquid. The charging system has been modified to decrease the uncertainty of the title in the case of mixtures. As well as for the isochoric apparatus a vacuum system was created in order to allow more shots to recover and weigh the lost mass. Although this apparatus has been repeatedly tested with known gases in order to validate the tests Regarding the experimental refrigeration plant, after put it back in operation, we evaluated the performance of the refrigeration cycle cascade operating with CO2 and then with mixtures of CO2 + R23 in low temperature cycle. For the control both of valve laminating and of heat load we have chosen to use PID control, which aims to simulate the behavior of a refrigerator for freezing food. To improve the experimental plant, we used a volumetric flow meter on the high temperature cycle, after change of Labview software, which processes the data acquired from the plant, and we inserted a bypass system in the low temperature cycle; this system allows to recover the oil in circulation during the transition, in which the device operates in a partial load

Full textDue to the European and Italian laws in force, the waste management integrated systems will be necessarily organized with the aim of landfilling only pretrated and at least partly stabilized waste; these “new” refuses, having very different characteristics with respect of the raw waste, will allow a significant reduction in terms of biogas production and leachate pollutant load, even if this reduction will be not enough to result compatible the environment and the long-term behaviour is still to be understood; new disposal conditions and new management strategies must be defined, aiming at facilitating the development of the biodegradation processes, the achievement of the stabilization conditions and the shortening of the aftercare phase. Based on these issues, the present research focused on the behaviour of different pretreated waste and their mixtures once landfilled; in particular, Municipal Solid Waste Organic Fraction (MSWOF) at a different biostabilization degree (15 and 90 days), coming from a selection and composting plant, and bottom ash (BA) from MSW incineration were used to realize several landfill reactor in semipilot scale; such reactors were managed in different ways (anaerobic and semi-aerobic conditions), in order to evaluate the potential emissions via leachate, the sanitary implications and the length of the post-closure phase. The wastes were initially and periodically characterized in terms of several chemical, microbiological and geotechnical parameters; besides leachate characteristics and settlements of the bulk waste were monitored. Prior to be landfilled, the leaching behaviour of the waste and mixtures used was investigated, thus verifying whether the parameters analyzed in the eluates produced were below the limits fixed by Italian and European laws in force for non-hazardous waste. prEN 12457-1, prEN 12457-2 tests were executed, along with some other characterization tests: Toxicity Characteristic Leaching Procedure (TCLP), NEN 7341, which provided information about the maximum potential emission from the waste (availability) and Acid/Basic Neutralization Capacity (ANC/BNC), which furnishes the acid/base need by the waste to reach a predetermined pH, and pH static test, through which the heavy metals solubility curves as a function of pH can be developed. The eluates obtained in each test were characterized in terms of heavy metals, chlorides, sulphates, Total Dissolved Solids (TDS). The results obtained were used to compare the Italian and European laws regarding the acceptance of waste in landfill as well as the different behaviour of the waste studied as pH and liquid to solid ratio (L/S) changes. BA showed the maximum ANC value, resulting in a higher buffering effect exerted by this material, once landfilled; due to such a behaviour, the solubility of heavy metals in leachate is probably significantly reduced; besides, the length of the acid phase in the anaerobic metabolism can be shortened, allowing both a faster establishment of the methanogenic conditions and a limited production of biogas. The solubility curves showed different behaviour, depending on the organic content of the waste; in particular, minimum values of the heavy metal solubility corresponded to slightly alkaline pH (7÷9) for wastes with higher inorganic content, such as BA, and for neutral pH for predominantly organic waste, such as MSWOF. MSWOF, BA and their mixture resulted non-hazardous according to Italian law; with respect to the European Directive MSWOF resulted hazardous, due to the more restrictive limits. Arising from the results obtained by the study of the reactors, the anaerobic co-disposal of BA and MSWOF biostabilized at 15 days, in the percentages here used (30-70% by weight), allowed to reach some advantages in terms of both leachate organic load and a more rapid definitive closure of landfill, due to the more rapid settlements exhaustion and stabilization; besides, final settlements results lower. The presence of BA behaved as a rigid skeleton which firstly retarded the start of settling and secondly hindered the settlement rate, thus leading to a lower value reached at the biological stability occurrence. Despite the space increase made available by the biodegradable fraction consumption, the bulk waste did not settle appreciably because the BA, by aggregating the residual waste particles, made a sort of “cement”. Probably BA supplied aggregating and stabilizing properties to the materials which they are added to and functioned as structural and support material. The air supply to one of the mixed reactors, allowed to accelerate the biodegradation process, providing a significant reduction in the leachate organic load and a faster mechanical stabilization of the bulk waste; nevertheless, the aeration implies some burdens: proper air and water addition for the biological aerobic metabolism, costs increases due to the air needs, clogging of the air supply pipes, homogeneous water distribution and circulation. By the study of the monolandfills, containing MSWOF 15 and 90 days biostabilized, the release was significantly reduced (of about 70-80%) in the leachate from the latter and also a higher mechanical stability was reached. It is noteworthy that for all the reactors, the total amounts of heavy metals released during the experimental activity represented only a very limited fraction (in some case lower than 10%) of the initial content measured in the bulk waste. Consequently, leachate hazardousness resulted lower, on the other hand, significant heavy metals release can occur in case of pH or Eh changes in the landfill, due for example to oxygen and water entry because of the exhaustion of biogas production and problems at the isolation system. The data obtained showed that co-disposal of BA with MSWOF, being previously partly biostabilized, can allow to achieve a more rapidly plateau conditions of both the organic load released in the leachate, and the settlements of the bulk waste, unless for the operating conditions and the waste fraction percentages tested in this study. This implies some clear advantages in terms of the postclosure management. Moreover, leachate organic load and settlements trends were shown to be quite similar in the case of codisposal of BA and partly biostabilized MSWOF, and in the case of completely biostabilized MSWOF landfilling; thus co-disposal seems to represent a valid alternative to a more stressed and expensive pre-treatment phase. Finally, a strong correlation between the biochemical parameters of leachate and the mechanical behaviour of the bulk waste was demonstrated to exist. This correlation can be used as a valuable tool in both designing and modelling of landfill plant. It can also help in planning the best management practises as well as the economic implications related to either life or post-closure period of the landfill.

Full textThe aim of the study was to analyse the feasibility of recycling and reuse of waste and to carry out an environmental analysis of three case studies that are currently destined for landfill because they cannot be recycled by the current supply chains and are therefore not used as secondary raw materials. The three case studies were object of three research public projects aimed to assessing the applicability of different strategies to use as secondary raw materials and the environmental impacts of recycling. The first case study focused on the recycling and reuse of materials containing asbestos. In particular, the atmospheric emissions related to the thermal treatment process were evaluated, and the consequent environmental impact assessment using the LCA method. The second case study assessed the feasibility of recycling household hard plastics. The possibility of separating the different hard plastics by density was demonstrated, and it was possible to obtain a blend with good mechanical properties composed of post-consumer and post-industrial plastics. The LCA analysis showed a considerable reduction in environmental impacts compared to the production of new virgin plastics. The third case study analysed the possibility of reusing cellulose from Absorbent Health Products (AHP) obtained from Fater S.P.A.'s patent recycling process. Tests carried out during the project allowed to evaluate the use of recycled cellulose both for the production of insulating panels and as cellulose flakes. It has been demonstrated that recycled cellulose has the same properties as virgin cellulose for the thermal insulation of buildings and that the application of insulation panels is a valid method of use with a low environmental impact.

Full textDespite the fact that a substantial part of the world's population still lives at subsistence levels of consumption, there are indications that human activities are already overstretching the globe's limited resources and environmental services. The cause of this overstretch is the high per capita use of resources and environmental services from unsustainable consumption and production patterns in developed countries. The Kyoto Protocol and The European Commission have set a target of a 12% reduction in GHG emissions by 2012 and a 20% reduction by 2020. Italy's emissions reduction target under the Kyoto Protocol is to reduce by 2012 greenhouse gas emissions by 6.5 per cent below base-year levels. There is an increased concern about our environmental impacts and how we can reduce GHG emissions. The efforts to reduce the environmental impacts are generally targeted to energy plants and transports. There is much less awareness about the environmental impacts of the food supply chain. This lack of awareness is even more striking if we consider that it is widely acknowledged that agriculture has a great impact on the environment and that about 50% of food produced worldwide is lost from farm to fork. In light of this analysis, in this research I have quantified food waste produced along the food supply chain in Europe and in Italy and I have evaluated its environmental impacts. With this research I show the importance of diminishing food chain's inefficiencies to minimize our environmental impact and to reduce climate change.

Full textThe research target is the assessment of energy and environmental rating systems effectiveness in reducing buildings environmental impacts. The present work consist of two sections. In the first part the national version 2011 of the ITACA Protocol has been evaluated by an inner check between building better performances and reached rating scores. The relevant criteria has been implemented to a residential building with energy performances within the limit of the law and others 4 buildings with the same form and location, but with better energy performances by different envelopes and power systems. The rating system results well harmonized and weighted, because performances and scores are directly corresponding. In the same buildings a LCA analysis has been carried out, that has highlighted the environmental impacts relevance of utilized materials, water consumptions, and end-life scenarios in the high energy performances buildings during their management phase. ITACA Protocol criteria has been chosen to control these impacts. The second section deals the ITACA Protocol implementation to 20 houses study cases: 16 new constructions interventions and 4 refurbishment. These results have been compared with the average energy performance of an Italian residential estate, to evaluate the contribution to climate change adaption. Intervening on 25% of the current Italian housing estates built between 1952 and 2001 and on 15% of the built estates before 1952, with ITACA Protocol results in a reduction of the energy load in the housing sector of 20,66%, and of 16% in CO2 emissions. At the same time the materials and transport criteria show that it could be possible to save energy if the retrofit interventions were to be located in the city centers, near the public transport stops and near the main public and commercial services. Whilst from the technical point of view the application could be easily adopted, the high costs of these interventions still have a long payback time.

Moench) as a dedicated bio-energy crop and highlights the benefits and risks associated with the use of early, medium-late and late sorghum genotypes to generate electricity by direct combustion in a biomass power plant. The dynamics and duration of the field drying process were simulated through the development of a specific model ("sorghum haying model"), which integrated with CropSyst, was used to perform a production risk assessment analysis estimating the biomass losses (respiration and mechanical), the haymaking failures and consequently to quantify the amount of dry baled biomass available for the power plant. In addition, the number of hectares needed to plant sorghum and the probability to exceed the threshold of 64000 Mg DM y-1, necessary to feed a biomass power plant in Oltrepò Pavese, were estimated. A complete Life Cycle Assessment (LCA) study was carried out in order to evaluate the environmental impact of the three sorghum genotypes involved in this study. The LCA study takes into consideration the use of winter wheat straw as an additional biomass source to satisfy the total biomass power plant needs (94000 Mg DM y-1). Particular attention was given to the soil organic C change (ΔSOC) due to straw removal and haymaking failures soil incorporation. Early genotype showed the best biomass production and energy performance as well as the highest probability to exceed the threshold of 64000 Mg DM y-1. The LCA results did not show significant differences between genotypes although the lower environmental impact, has been achieved by the late genotype due to the highest amount of haymaking failures incorporated in the soil.

Full textNowadays, the qualitative and quantitative assessment of environmental impacts produced by every human activity is a topical field of research. As a matter of fact, all over the world there is an increasing attention about the environmental issues and influences exerted by productive and management sectors. In particular, the management of waste is a crucial sector involving important aspects of our life as well as it produces several environmental impacts that have to be adequately monitored and managed in a sustainable development perspective. In the first part, this study was focused on the evaluation of the positive and negative impacts caused on different environmental components by several municipal solid waste management systems defined at provincial scale. This assessment was performed by means of two different Life Cycle Assessment (LCA) procedures called WISARD and SimaPro, respectively. The LCA procedures were able to calculate the consequences produced by the whole system as well as by each phase. While, in the second part, the study was focused on the collection and transport of materials to determine environmental and economic effects for ten municipalities from 1000 to 10,000 inhabitants. The performed analysis taken into account a kerbside collection system of all recyclables, glass excepted, with a percentage of separate collection varying in the range of 35% – 80% and transport to composting of putrescibles, RDF pressed balls production and incineration, final landfilling. There are other two scenarios, for 80% separate collection, that consider different alternatives of treatment for residues as dry residue sorting and final landfilling or direct disposal in landfill. The obtained results pointed out that the increasing of the percentage separated collection involves an environmental performances’ improvement of management system and an environmental benefits’ increase. For high percentage of waste separated collection incineration doesn’t weighed upon impact’s results respectful to dry residue sorting. The results are similar for both Life Cycle Assessment procedures in qualitative terms. xviii With regard phase of collection and transport for communities results show how impacts rise such as community’s size; opposite management costs in term of Euro/inhabitant/year increase for the little communities but don’t depend by the number of inhabitants for the communities with a population major of 5000 inhabitants. The multi-criteria analysis was developed giving the same importance to both economic and environmental variables. The principal result obtained was that the municipalities up to 4000 inhabitants must get together to optimize both environmental and management costs. [edited by author]

Full textThe livestock breeding in Italy plays an important role in the agri-food sector, spanning from social to economic and to environmental aspects. Italy is a leader in the production of quality milk for direct consumption and is the main European country producing PDO cheeses. However, milk production carries impacts on the environment, as livestock farming contributes to greenhouse gas emissions, mainly resulting from animals’ digestion system, manure management and feed purchase, as well as pollutants. With the aim of a sustainable agricultural and agri-food development, it is important to identify, through Life Cycle Assessment (LCA), main criticalities related to the dairy sector, in order to adopt environmental mitigation actions. In this regard, the EC has developed the Product Environmental Footprint (PEF) methodology and specific Category Rules (PEFCR), harmonizing the methodological choices of LCA and providing objective criteria to compare the eco-compatibility of products. The LIFE TTGG (The Tough Get Going) project applies the PEFCR, calculating the environmental performance of the Grana Padano and Comté PDO supply chains and laying the bases for transforming the environmental problems arising from the activities of individual producers into opportunities for improvement, with a view to the Country's ecological transition.

Full textIn order to reduce the use of pesticides products and increase the resilience of wheat cultivation, in the context of climate change, it is necessary to fully understand the interactions and relationship between agronomic techniques with low environmental impacts and positive varieties traits. The general aim of this study is to characterize and identify the most suitable wheat varieties to achieve low environmental impact cultivation of common wheat. One experiment, carried out during three years at an organic farm, characterized 24 accessions of common wheat. The surveys carried out concerned both the agronomic, the nutritional, and the nutraceutical components. Some accessions registered excellent agronomic performance. A second study aimed to characterize, from a nutritional and agronomic point of view, different genotypes and evolutionary populations of common wheat, observing how they are influenced by different environments and meteorological trends. Some varieties in favorable pedoclimatic conditions reached extremely high production values, while in different contexts, they recorded lower values. In contrast, the evolutionary Bioadapt population registered high stability, in terms of production results achieved. The third research studied some aspects of common wheat physiology, to understand a physiological characteristic of plants, with particular relevance and important implications for sustainable cultivation of common wheat. The aim was to identify the common wheat varieties with a higher potential allelopathic activity, through the analysis of the initial root growth of the wheat plant and surrounding weeds. 30 cultivars of common wheat were selected and compared, while the perennial ryegrass was employed as weed model species. The allelopathic capacity seemed to be not simply a dose-dependent response to the molecules emitted in the growing substrate. The characterizations of the varietal resources carried out in the present study represent a valid starting point for future breeding programs, to obtain suitable varieties for low-input production systems.
