    Conventional methods for chromium removal from industrial effluents may be limited by technological or economical constraints, especially when they are applied to dilute metal solutions. Thus, biotechnological processes, which are efficient at low metal concentrations and require the use of fewer chemicals, may play an important role. The chromium recovery proposed here is based on the specific uptake of this metal by acidophilic fungi. Fifty acidophilic fungal isolates from the Río Tinto basin, an extreme acidic environment, were tested. Most of them were resistant to Cr(III) and Cr(VI) solutions at concentrations up to 10 mmol/L. The influence of different experimental conditions was evaluated (medium concentration, kinetics, requirement of induction etc.). Fungal isolate 143 was able to remove 63% of Cr(III) at 0.1 mmol/L, 74% at 1 mmol/L and 21% at 10 mmol/L. These are the best Cr(III)-fungal-uptake results at acidic pH described in the literature so far. It should be possible to use these acidophilic fungi, for example in tannery wastewater, as they can resist chromium concentrations and pH values found in these effluents (between 6.5-7.5 mmol/L Cr III and pH as low as 3-4)

    This work performs a comparative life cycle assessment (LCA) of two fuels for heating boilers, namely wood chips and oil. The LCA methodology allows comparing the environmental impacts of the two analyzed fuels, thus assessing which is environmentally more advantageous. The study is focused on Mediterranean forests located in the Argençola region (Catalonia, northeastern Spain) by applying forest management practices focused to ensure a sustainable exploitation. The direct use of wood chips as a fuel for boilers simplifies notably the number of processes involved in producing such a fuel. The results presented clearly show the environmental benefits of using small-scale produced wood chips instead of fossil oil by analyzing representative impact categories defined by the CML and EDIP methods, even when considering the changes in the carbon stock in the forests under analysis due to the management approach adopted. A sensitivity analysis has also been conducted to assess the impact of the data with higher uncertainty on the final LCA results.

    Biofuels are nowadays considered a questionable environmental alternative to fossil fuels. In that context, this work analyses the environmental impacts when introducing rapeseed on the traditional and current wheat and barley agricultural rotation by means of a comparative life cycle assessment (LCA). The introduction of rapeseed, the correctness of its conversion to obtain straight vegetable oil and its use as self-consumption biofuel in tractors are evaluated. Life cycle assessment is used in this work to evaluate the impacts of different considered scenarios. A sensitivity analysis has also been conducted. The results presented show a modest environmental improvement (diminishment of 6 out of the 10 analyzed environmental impacts) when introducing rapeseed to local crop rotations and its partial conversion to oil to be used as fuel in existing diesel engines. Additionally, the ratio between the energy obtained and the total energy input shows moderate positive results when comparing the latter case with the current one. Results from this study can be used to support research and decision making to assess the convenience of introducing alternative fuels in agricultural exploitations

    The straight use of vegetable oils as fuel in diesel engines entails adjusting several physical properties such as density and viscosity. By adequately heating the vegetable oil before entering the injection system, its physical parameters can reach values very close to that of diesel fuel. Consequently, by properly adjusting the temperature of vegetable oils used as fuel, it is possible to improve their combustion performance, thus avoiding premature engine aging due to incomplete burning. In this study the density and viscosity of several vegetable oils are studied within a wide variety of temperatures. The optimal range of temperatures at which each vegetable oil should operate in order to adjust its properties to those of automotive diesel and biodiesel is then found. Additionally an empirical relationship between the dependence of viscosity with density is presented. Thus, by means of the above-described relationship, through measuring the density of a given oil, its viscosity can be directly deduced

    The oil price instability and the measures taken to reduce the increase in greenhouse gas emissions are the main factors promoting the development and use of environmentally friendly energies. From an energy efficiency point of view, biofuels constitute a renewable energy source and its use helps to reduce energy dependency on fossil fuels. The most used biofuels for transport worldwide are biodiesel (BD) and bioethanol. However, there are other options such as straight vegetable oil (SVO). SVO can be small-scale produced in local cooperatives through pressing, filtering and conditioning processes which are much simpler than the ones required for BD production. In this study a comparative life cycle assessment (LCA) of two biofuels obtained from Spanish rapeseed, namely small-scale SVO and large-scale BD, is performed. The LCA methodology allows the two biofuels¿ production and their rate of consumption in a vehicle (a truck) to be compared. In this manner, it is possible to assess which is environmentally advantageous: to use SVO directly as biofuel or to convert it to BD. Moreover, LCA is used in the study to calculate the energy return on investment index (EROI) and an energy conversion ratio to evaluate which biofuel is more energy efficient. The obtained results show the environmental benefits of using SVO instead of BD by analyzing representative impact categories defined by the CML and EDIP methods. A sensitivity analysis has also been conducted. EROI indexes for SVO and BD production show a clear preference for SVO as compared to BD.

    The use of straight vegetable oil (SVO) as biofuel has been recognized as a valid substitute of diesel fuel in the agricultural sector under specific circumstances. Its direct use reduces most of the chemical processes involved when converting it into biodiesel, thus lowering harmful emissions. This study presents the economic analysis of a self-supply farming model that uses rapeseed as its fuel base. This model addresses agricultural environmental concerns and can even minimize dependence on the fluctuating costs of diesel fuel. The use of SVO in agriculture can help reduce farmers’ vulnerability to fossil fuel prices. The economic evaluation of the model proposed in this study shows clear economic benefits of introducing rapeseed to the traditional crop rotation of wheat and barley. The key factors analyzed in this model are diesel fuel price, diesel fuel grants and crop aids. The current situation in Spain favors the use of diesel fuel in agriculture rather than rapeseed SVO due to an 8% profit difference. However, results show that changes in key factors slightly affect the profit margin, calculating a difference of only 3.7% for particular factor combinations. Combined environmental-friendly agriculture supporting policies are necessary to cover this slight profit difference to promote this biofuel

    The objectives of the research here described were to put in evidence the eco-profiles of two product-systems concerning bovine leather manufactured in Italy and Spain, to identify their hot spots and to find out if the different technologies and cooperative management solutions adopted led to significant environmental differences in the two systems analysed. The environmental impacts of two systems were analysed by means of the life cycle assessment (LCA) methodology. At the macro-phase level, tanning resulted to be the most burdensome phase for almost all impact categories in both systems. At the level of the specific tannery phases, the main hot spots were tanning, dyeing-retaining and soaking in the Italian system, soaking-liming, tanning and retanning in the Spanish one. The main differences between the two systems and a few options for improvement were identified at three levels: energy mix, industrial processes and solid waste management. Despite the technological and waste management dissimilarity of the two systems, their total environmental burdens appeared quite similar. However, relevant differences in the most burdening phases, operations and substances are highlighted in this paper. Improvements in both systems should be aimed at by means of an optimisation of tanning processes and reduction of chemicals use. Further studies dealing with inventories of recovery processes and landfill disposal of wastes are recommended.

    This chapter presents a method to produce rapeseed and process it to obtain rapeseed oil and rapeseed cake meal from a small-scale point of view. It also shows how rapeseed oil can be used as fuel in diesel engines for agriculture self-consumption. A production, processing and use-as-fuel model for rapeseed oil is also presented, analysing environmentally and economically the use of rapeseed oil as fuel compared to other agricultural production alternatives. The results are evaluated for dry Mediterranean area conditions

    La dependència actual dels combustibles fòssils en la majoria de sectors industrials i domèstics no és sostenible ni a curt ni a llarg termini. Això està obligant a plantejar alternatives a la majoria de sectors industrials especialment encaminades a l’estalvi energètic i la utilització d’energies renovables. A més a més en el cas dels combustibles, la Unió Europea està incentivant l’ús de biocarburants degut als compromisos assumits en el protocol de Kyoto. Els biocarburants més comuns pel cas del transport són el biodièsel i el bioetanol, que en la majoria dels casos, es produeixen a gran escala i presenten seriosos problemes ambientals i socials tal i com citen els treballs de diversos autors. En aquest escenari és interessant proposar i avaluar ambientalment altres biocarburants no presents actualment en el mercat. En aquesta tesi es proposen i s’avaluen ambientalment (mitjançant l’anàlisi del cicle de vida, ACV) dos biocombustibles, l’oli de colza pel cas del transport, comparat amb la seva conversió a biodièsel i l’estella forestal per a calefacció comparada amb el gasoil. En l’últim apartat d’aquesta tesi es realitza una caracterització de sis olis vegetals, per tal de determinar la temperatura òptima de preescalfament per ser utilitzats com a biocombustibles en motors dièsel actuals. Conjuntament amb aquesta caracterització es parametritza la densitat, viscositat i tensió superficial d’aquests olis en funció de la temperatura.

En el último apartado de esta tesis se realiza una caracterización de seis aceites vegetales, para determinar la temperatura óptima de precalentamiento para ser utilizados como biocombustibles en motores diesel actuales. Conjuntamente con esta caracterización se parametriza la densidad, viscosidad y tensión superficial de estos aceites en función de la temperatura

    The current dependence on fossil fuels in most industrial and domestic sectors is not sustainable in neither short nor long term. This is promoting alternatives to most industries, especially focused on saving energy and using renewable energy. Moreover, the European Union is encouraging the use of biofuels trough the commitments in the Kyoto Protocol. The most common biofuels for transport are biodiesel and bioethanol, which in most cases, are large scale produced and involve serious environmental and social problems according to several authors. In this scenario it is interesting to evaluate other alternative fuels, being environmentally friendly and not currently present in the market. This thesis presents and environmentally analyses two biofuels using life cycle assessment (LCA) methodology. One is straight vegetable rapeseed oil used for truck transport compared to rapeseed biodiesel. The other is wood chips for heating compared to diesel as heating fuel. In the last section of this PjD a characterization of six vegetable oils is performed in order to determine the optimal preheating temperature to use it as biofuel in current diesel engines. Together with this characterization, the density, the viscosity and the surface tension of different vegetable oils are parameterized for a wide range of temperature.

    ABSTRACT: Obtaining energy from forest chips is a technology widely used in many regions. There are currently many studies and applications on the use of forest biomass [1,2], mainly promoted by policies aimed to reduce greenhouse gases. The forests of the Mediterranean area are characterized by a mountain relief. This orography makes difficult the selective biomass extraction from the forest. Thus, the biomass is accumulated in the forest and becomes a serious danger for wildfires. Forest fires are considered the most important natural impact in the Mediterranean region due to its effect to ecosystems, as some authors state [3,4]. This study aims to compare by means of LCA methodology the use of forest chips and diesel fuels in a boiler, focusing on the difficulty of extracting the wood from a Mediterranean forest area. In the Mediterranean area there are no environmental studies centred on the extraction of timber from forest areas without affecting the life in the forest. This work presents an LCA, where the difficulties of extracting the biomass from the forest and its use in heating boilers are presented.

    This work proposes and analyses a model for an agricultural fuel self-supply exploitation. The model is based on the current extended crop rotation of wheat and barley in Anoia region (Catalonia, Spain). The introduction of rapeseed to the current crop rotation and its conversion into oil to be used as agricultural fuel is presented. Life cycle assessment methodology is used to carry out an environmental and an economic assessment. Environmental results show a preference for the vegetable oil based scenario in terms of CO2 equivalent emissions and energy consumption as well as no major difference in land used for the considered scenarios. Economic assessment shows a preference for the rapeseed introduction in the current crop rotation agricultural system without converting the seed into oil and using it as biofuel. The basis to develop the life cycle social assessment is also presented, calculating a social impact category as an example.

    Biofuels nowadays are an important topic of study. The most significant point is the availability of bioethanol or biodiesel and their production from different raw materials. It is already known that large scale production of first-generation biodiesel cannot be seen as an alternative to fossil fuels due to land requirements, competition with food, increase in fertilizer requirements and pressure on tropical forests among others. This fact does not necessarily apply to second-generation biofuels or small scale niche productions. Straight vegetable oil (SVO) can be used directly in diesel engines with minor modifications. Our proposal is a small-scale SVO production system for self-supply in agricultural machinery. In this paper a model to provide SVO to local farmers in a specific area in Catalonia (Spain) is presented. We also present a discussion about the regulations to be changed in order to make possible the incorporation of SVO as engine fuel in diesel vehicles and a comparative analysis between the emissions of tractors fed with SVO and petrodiesel. Moreover a quantitative economic analysis of modifying diesel engines and long-term operability costs are shown and a firstrun economic analysis comparing the actual crop rotation with the proposed one and some alternatives is studied.

    Actualment els biocarburants ocupen una important àrea d’estudi, essent el biodièsel i el bioetanol els més utilitzats en el nostre territori. La major part d’aquests biocarburants són de primera generació i la seva fabricació a gran escala presenta seriosos problemes ambientals i socials a causa de la gran demanda de terres agrícoles [1-2]. Tot i això, la necessitat de reduir l’emissió de gasos d’efecte hivernacle n’incrementa la seva demanda. Actualment, és interessant pensar en implementar altres biocarburants no presents al mercat espanyol, com és el cas de l’oli vegetal fabricat a petita escala. La producció d’oli vegetal és més senzilla que la de biodièsel, doncs inclou menys processos i menys consum energètic. L’oli vegetal obtingut del premsat de llavors de plantes oleaginoses es pot usar com a biocarburant realitzant una petita modificació al sistema d’alimentació dels motors dièsel convencionals. En alguns països europeus, com Alemanya i Dinamarca, ja s’utilitza l’oli vegetal com a biocarburant, principalment en maquinària agrícola, mentre que a Espanya no es troba a les gasolineres i només el fan servir alguns particulars [3]. Aquesta fitxa mostra els resultats econòmics de la introducció de la colza en la rotació de conreus clàssica a la zona de l’Anoia i l’autoconsum de l’oli de colza com a biocarburant en maquinària agrícola. Els resultats s’han obtingut mitjançant un model desenvolupat per a calcular el benefici obtingut en una explotació a partir de paràmetres com els rendiments de les collites de la zona de l’Anoia. Es considera l’oli fabricat a partir de la llavor de colza, ja que és possiblement la planta oleaginosa que millor s’adapta al clima mediterrani.

    La utilització de l’oli de colza com a carburant és una tecnologia que ja s’utilitza a altres països europeus com Alemanya i Dinamarca, degut principalment a dos factors: el gasoil agrícola està menys subvencionat i el grau de conscienciació mediambiental és major en aquest països. L’oli de colza és un biocarburant que s’obté del premsat de llavors de plantes oleaginoses i que, realitzant una petita modificació al sistema d’alimentació dels motors dièsel, pot ser utilitzat com a combustible. La fabricació de l’oli vegetal en front a la del biodièsel és més senzilla, ja que inclou menys processos i menys consum energètic. [1] En aquesta fitxa es pretén fer una breu explicació de la producció i consum de l’oli de colza, destinat a ser utilitzat directament com a biocarburant en maquinària agrícola. Ens centrarem en l’oli fabricat a partir de la llavor de colza, ja que possiblement és la planta oleaginosa que millor s’adapta al clima mediterrani.

    In the leather industry, in addition to the extrinsic contamination attributable to chemical products not absorbed by the hides, there is intrinsic contamination produced by the hides themselves. From each 100kg of raw material, 15kg of solubilised protein will end up in wastewater in the early stages of the process of transforming hides into leather. These proteins contain nearly 18% of nitrogen. In this study it is proposed to recover organic nitrogen from the proteins present in the effluents of the beamhouse operations of hides and the subsequent revalorization of the protein fraction obtained. This work seeks to characterize (the chemical oxygen demand (COD), total nitrogen, ammonium nitrogen, total soluble nitrogen, particulate nitrogen, organic nitrogen and protein) the wastewaters, individually or in groups, of the various beamhouse operations (soaking, unhairing-liming, washing, conditioning, deliming, bating, washing and pickling) with hair recovery. The studies are presented of the determination of the pH value (adjusted by means of buffers of acetic acid/sodium acetate) at which the greatest precipitate of the protein fraction is produced. In addition, the following tests were performed to characterize these precipitates: determination of the quantitative composition of the main components of the protein fraction (humidity, proteins, free amino acids, fats and other matter soluble in dichloromethane and ash); heavy metals content, calcium, magnesium, potassium and sodium and the composition in total amino acids with prior acid hydrolysis of the protein fraction with 6N hydrochloric acid.

    L'objectiu del projecte presentat aquí (que forma part del projecte CICLE), és conèixer la situació actual d'aprofitament i reciclatge de residus del sector paperer català i fer propostes de millora seguint els principis de l'ecologia industrial. Per això s'ha fet una diagnosi identifcant i quantificant els diferents residus produïts per aquesta indústria a Catalunya i el seu destí. Els residues de depuració grollera van actualment a abocador i els fangs de depuració, en una proporció elevada, tampoc no s'aprofiten. Les principals millores proposades són, per tant: la utilització de la tecnologia Rofire per a l'aprofitament energètic del residu de depuració grollera, que reduiria en un 85,8% les emissions de CO2 i que seria econòmicament viable quan el cost de l'abocador sigui d'uns 50,88€/t de residu i la cogeneració utilitzant fangs de depuració com a combustible. Aquesta darrera opció s'hauria d'estudiar a fons per a cada empresa en particular.

    This work has been funded by the European Commission through the Chrom6less Project (CRAFT -1999-71638). The objectives of the project were: - Establishment of the analytical methodology which provided reproducible results that may be free of interferences. - Identification of the factors that facilitated or impeded the transformation of Cr(III) to Cr(VI). - Establishment of the best conditions that allowed the production of chromium(VI) free leather, even during the life of the product, in contact with environmental agents such as light or heat. The following partners participated in the project: Inpelsa, Dercosa, Proquip, Igualada Leather Technology School, CID-CSIC and Miguel Hernandez University, from Spain, Gmelich, Knoll Sitzleder, and Lederinstitut Gerberschule Reutlingen from Germany, and Conceria Il Cigno, Calzaturificio Accademia and Stazione Experimentale from Italy. Hundreds of samples have been analysed during the project. In order to study the influence of several factors in chromium (VI) formation, a lot of skins/hides have been produced. Several leather articles (hides for clothing, footwear, upholstery, leather goods and furniture upholstery and skins for suede and double face)) have been manufactured free from Cr (VI). The main results obtained were: - The new analytical method CEN/TS 14495 has been validated. - Protective measures for the prevention of chromium (VI) formation have been identified. - New formulations for several hides/skins have been developed. - A handbook for the production of chromium (VI)-free leather has been published. The main conclusions of the project were: - The Chrom6less Project has shown that most of the skins/leathers did not contain hexavalent chromium. - It is now possible to confidently determine the Cr(VI) content in all kinds of leather regardless of their colour. - The application of protective measures developed in the Project allows leather to resist the effect of ageing without the formation of Cr(VI).
