Resumen
Abstract As a result of increasing industrial activity and stricter application of environmental standards, pressure is being brought on Industries to improve the quality of their effluents. To achieve these goals, cost-efficient and high-performance wastewater treatment processes are needed. Recently, tests were completed on the treatment of ground wood, TMP and de-inking process effluents at the Daishowa, Quebec, pulp and paper mill. The biological treatment used was a fixed-film process known as the “Biocarbone” process. These tests demonstrated conclusively the high effectiveness of the Biocarbone process at COD loads of up to 10 kg/m3.day. This represents a major savings of space when compared to conventional waste activated sludge processes with COD loads of 2-3 kg/m3.day. The object of the test was to verify BOD5 levels, TSS removal and toxicity levels with respect to existing environmental standards. At all times and for all conditions tested, the Biocarbone process met the accepted standards of 5 kg/t of BOD5, 8 kg/t of TSS, and total removal of toxicity on a monthly basis

Resumen
Biocarbone aerated biofilters were developed more than ten years ago. Almost one hundred plants worldwide provide complete treatment in very short hydraulic retention time. This allows to construct compact plants in sensitive areas such as inner cities, sea or mountain resorts. The filters can be adapted to high effluent qualities expected by the European directive on wastewater treatment. Full oxidation of ammonia can be achieved in less than two hours. A plant for complete removal of nitrogen has been operated for more than a year in Denmark to meet Europe's most stringent effluent requirements by using an anoxic biofilter in series with the Biocarbone. A new aerated biofilter, turning the Biocarbone principle upside down, is presented : a synthetic floating material allows enhanced performance, simplified backwash and a combination of anoxic and aerobic zones in one reactor. Effluent quality of less than 10 mg/l for all components (BOD, SS, TN) was demonstrated in a one-year long on-site test in Denmark and the first facility for 60 000 population equivalents is under startup. Full scale results of the upflow floating filter, Biostyr, are presented for nitrogen and phosphorus removal according to the European directive.

Resumen
The BIOCARBONE process is a recently developed method for wastewater treatment. High concentrations of active biomass attach to an expanded shale medium in an aerated, packed-bed filter. High-rate biological treatment and in-situ removal of suspended solids are claimed as advantages of the process. The pilot-scale evaluation aimed to assess the performance of the process and its economic feasibility for use in the UK. Carbonaceous oxidation of settled sewage and tertiary nitrification of secondary effluent were investigated in two pilot-scale reactors. Carbonaceous oxidation produced a good-quality effluent at volumetric loading rates up to 4.1 kg BOD5/m3.d (9.2 kg COD/m3,d). Automatic backwashing of the filter was required and problems were encountered with blockages of the process aeration grid. Tertiary nitrification achieved greater than 90% ammoniacal nitrogen (NH3-N) removal at volumetric loading rates up to 0.58 kg NH3-N/m3.d (0.63 kg KJN/m3.d). The economic evaluation indicated that costs of sewage treatment using the BIOCARBONE process would be comparable to those of the activated sludge process for sewage treatment works greater than 50,000 population equivalent. The results show that the BIOCARBONE process is suitable for both the carbonaceous oxidation of settled sewage and the tertiary nitrification of secondary effluent. The process may be an economic option for large sewage treatment works in the UK.

Resumen
The mechanism for the nitrate removal from wastewater in a submerged fixed film filter is reviewed and evaluated to demonstrate that the denitrification process is significantly reduced by the presence of oxygen. The kinetics were developed for a fully nitrate penetrated biofilm, influenced by oxygen. It was demonstrated that there is a linear reduction of the denitrification rate with depth of oxygen penetration, proportional to the oxygen concentration to the half power. For a partly nitrate penetrated biofilm the influence of oxygen is a function of the ratio between the penetration of oxygen and the penetration of nitrate without the influence of oxygen. The phenomenon was investigated in laboratory scale with biocarbone and biostyr as media and at a full scale biocarbone plant. The investigation was performed with organic matter in excess on a thin biofilm taken directly from a full scale plant. The results of the experiments with influence of oxygen fit the kinetic concepts well.

Resumen
To reach agreed-on climate goals, it is necessary to develop new energy carriers and industrial materials that are carbon-neutral. To combat global warming and keep Earth’s temperature from increasing by 1.5 °C, some of these solutions need to be carbon-negative. This study fulfills this criterion by producing clean hydrogen and biocarbon suitable for the metallurgic industry through the thermal decomposition of methane using biocarbon as a catalyst. Five different biomass samples were used to prepare biocarbons at a pyrolysis temperature of 1000 °C with a holding time of 90 min. When methane was cracked at 1100 °C with a holding time of 90 min, the highest hydrogen production was 105 mol/kg biocarbon, achieved using birch bark. The lowest hydrogen yield, of 68 mol/kg biocarbon, was achieved with steam-explosion pellets. All the biocarbons showed substantial carbon deposition from cracked methane on their surfaces, with the highest deposition on birch bark and spruce wood biocarbons of 42% relative to the biocarbon start weight. The carbon deposition increased with the decomposition temperature, the methane share in the purge gas and the holding time. The steam-explosion pellets, after deactivation, had a CO2 reactivity that was comparable to coke, a reducing agent that is commonly used in manganese-producing industries. About 90% of the potassium and sodium were removed from the biocarbon during catalytic decomposition of methane performed at 1100 °C. The alkali removal was calculated relative to the biocarbon produced under the same conditions, but with 100% N2 purge instead of CH4. After catalytic decomposition, the surface area of the biocarbon was reduced by 11–34%, depending on the biocarbon type.

Resumen
El propósito de esta investigación fue comparar las propiedades físicas y químicas de dos biocarbones en diferentes condiciones de pirólisis. En un reactor pirolítico se obtuvieron los biocarbones a partir de cáscara de cacao (BCA) y estiércol bovino (BSB). Las condiciones de pirólisis fueron: 200ºC/60 minutos; 250ºC/30 minutos(E2); 300ºC/30 minutos. El biocarbón se dejó enfriar, para luego tamizar, proceder con los análisis. El mayor rendimiento del BCA fue de 35,56% y del BSB de 71,11%. Los valores de pH de todos los ensayos fueron altamente alcalinos con rangos de 8,23 – 10,04. En la prueba de hidrofobicidad los valores fueron: 65,73 s biocarbón de cacao y 228,3 s biocarbón de bovino. El mayor porcentaje de ceniza fue el estiércol bovino con 89,94 %. El análisis de Infrarrojo indicó picos de grupos funcionales carboxílicos en ambos biocarbones a 300ºC por 30 minutos.

Resumen
About ten years ago, the first full scale Biocarbone aerated filter went into service in Soissons (France) for a capacity of 40 000 population equivalents. This compact wastewater treatment system combines aerobic biodegradation and filtration in one unit, eliminating the need for clarifiers and achieving high removal rates through fixed biomass. Since, a number of independent investigations have been performed to establish dimensioning criteria and process performance. This article summarises the reports of the US EPA, the Japanese JSWA, and the British WRC, as well as experiences acquired by cities and water authorities. In pilot and demonstration scale, reactor kinetics, sludge production and energy consumption was measured. Most reports agree on removal rates up to 4 kg BOD/m3 d or nitrification rates around 0.6 kg N/m3 d. Sludge yields ranged consistently around 0.8 kg SS / kg BOD removed, but oxygen transfer measurements varied from 7 % to 15 %. Full scale experience confirms these values, and operation results from large plants in North America are given. Several examples of using the Biocarbone process for low pollution residuals are demonstrated, including plants in Britain, Denmark and Switzerland. As tertiary installation fed with clarified secondary effluent, final residuals below 1 mg/l N-NH4 and 5 mg/l for SS and BOD can be achieved in a hydraulic detention time around one hour. On settled sewage, two hours detention time results in advanced secondary effluent quality below 5 mg/l N-NH4 and around 10 mg/l for BOD and SS. If an anoxic reactor is added, total nitrogen residuals below 10 mg/l can be achieved in about three and a half hours.

Resumen
The physical properties of biocarbon vary widely with the biomass used, and the temperature and duration of pyrolysis. This study identifies the effects of feedstock characteristics and pyrolysis conditions on the production of biocarbon and the corresponding properties for industrial applications. For coffee chaff and soy hulls, ash content and carbon content increased with pyrolysis temperature and duration. Ash content increased thermal conductivity and specific heat, and decreased electrical conductivity. Change in surface area with pyrolysis conditions was dependent on type of feedstock. Increased surface area corresponded with increased thermal and electrical conductivity. Increased carbon content corresponded with increased graphitization and thermal stability and decreased surface functionality. Properties of soy hull biocarbons were found to be similar to the properties of other biocarbons with industrial applications such as incorporation into polymer composites.

Resumen
Biological aerated filters combine bacterial degradation of pollution by fixed biomass with physical filtration in a single reactor.Several full-size plants with the BIOCARBONE process have established the compactness, ease of operation and high removal rates achievable with this advanced treatment system. Based on large-scale industrial experiences, a new biofilter design offering simplified operation and increased performance is presented. Design data for carbon and nutrient removal were collected during extensive pilot tests. Hydraulic conditions and pollution loadings were varied in order to optimize the biological and operational parameters of the filter. Carbon and ammonia oxidation as well as denitrification and suspended solids retention could be achieved with an overall hydraulic retention time of two hours.

Resumen
Wood-derived porous graphitic biocarbons with hierarchical structures were obtained by high-temperature (2200–2400 °C) non-catalytic graphitization, and their mechanical, electrical and thermal properties are reported for the first time. Compared to amorphous biocarbon produced at 1000 °C, the graphitized biocarbon-2200 °C and biocarbon-2400 °C exhibited increased compressive strength by ~38% (~36 MPa), increased electrical conductivity by ~8 fold (~29 S/cm), and increased thermal conductivity by ~5 fold (~9.5 W/(m·K) at 25 °C). The increase of duration time at 2200 °C contributed to increased thermal conductivity by ~12%, while the increase of temperature from 2200 to 2400 °C did not change their thermal conductivity, indicating that 2200 °C is sufficient for non-catalytic graphitization of wood-derived biocarbon.

Resumen
Ce travail examine la faisabilité de l'utilisation du biocarbone comme combustible alternatif dans les fours à chaux pour remplacer le charbon fossile dans le procédé Soda Ash. Les biocarbones ont été produits à partir de combustible solide de récupération (BC) et de bois (WBC). L'anthracite a été sélectionné comme combustible fossile de référence à remplacer et le biocoke issu de la coque de noix de coco a également été analysé pour comparaison. Les échantillons ont été caractérisés en termes de composition chimique et de propriétés physiques et thermiques. La stabilité thermique des combustibles et les performances de combustion ont été évaluées par analyse thermogravimétrique. L'évaluation des émissions a été réalisée en pyrolyse et en combustion, de l'échelle laboratoire à l'échelle pilote, de manière à reproduire les conditions extrêmes du four à chaux. Les résultats ont montré que la dévolatilisation a augmenté la stabilité thermique du biocarbone, rendant son comportement proche de celui de l'anthracite. Le biocoke et les biocarbones ont montré des températures d'ignition plus basses, mais un taux de combustion plus élevé par rapport à l'anthracite, le combustible le plus stable. Les émissions en CO2 des échantillons WBC ont été plus élevées que celles de BC. En ce qui concerne les composés organiques volatils, les hydrocarbures aromatiques polycycliques (HAP) ont été identifiés et quantifiés. Même si le biocarbone produit des HAP avec moins de cycles (<5) lors de la pyrolyse/combustion, ses émissions ont été plus élevées que celles de l'anthracite. Pour atténuer la réactivité du biocarbone, une co-combustion de 50/50 biocarbone/anthracite a été proposée, offrant ainsi les avantages d'une température d'ignition plus élevée et d'émissions plus faibles
This work investigates the feasibility of using biocarbon as an alternative limekiln fuel to substitute coal in the Soda Ash process. Biocarbons were produced from solid refuse fuel (BC) and wood (WBC). Anthracite was selected as the reference fossil fuel to be replaced, and biocoke from coconut shell was also considered for comparison. Samples were characterized in terms of chemical composition, physical and thermal properties. Fuel thermal stability and combustion performance were evaluated using thermogravimetric analysis. Emissions assessment was performed in pyrolysis and combustion from lab-scale to pilot-scale, so that extreme limekiln conditions were reproduced. The results showed that devolatilization increased biocarbon thermal stability, making its behavior close to that of anthracite. Biocoke and biocarbons showed lower ignition temperatures but a higher burning index compared to anthracite, which was shown as the most stable fuel. CO2 emissions from WBC were higher than those of BC samples. Amongst the volatile organic compounds released, polycyclic aromatic hydrocarbons (PAH) were identified and quantified. Even if biocarbon produced PAH with less rings (<5) in pyrolysis and combustion, its emissions were higher compared to anthracite. To mitigate biocarbon reactivity, a 50/50 biocarbon/anthracite co-combustion was proposed, thus offering the advantages of higher ignition temperature and lower emissions

Resumen
Ce travail propose une approche innovante pour la production, caractérisation et utilisation de catalyseurs biosourcés pour des applications dans les domaines de l'énergie et de l'environnement, afin de réduire le coût et l'impact des catalyseurs commerciaux actuellement utilisés. Le travail développé ici promeut une approche d'économie circulaire dans la mesure où des plantes issues de la phytoremédiation ont été employées pour la production de catalyseurs biosourcés, respectueux de l'environnement. Ces catalyseurs ont été utilisés pour produire des vecteurs énergétiques tels que l'hydrogène à partir des réactions de gaz à l'eau direct (water-gas shift, WGS) et indirect (reverse water-gas shift, RWGS), et pour la décomposition des polluants de NOx (deNOx). Les catalyseurs biosourcés ont été produits à partir de saule et fougère avec un contenu contrôlé en métaux introduit par imprégnation avant ou après pyrolyse à 800°C afin d'imiter l'hyperaccumulation (>3 g métal /kg biocarbone) dans un support carboné poreux. Les catalyseurs ainsi produits ont été testés pour les réactions de deNOx, ainsi que dans WGS et RWGS, et les dispositifs expérimentaux associés ont été développés et optimisés pendant la thèse. Ils ont été caractérisés en termes de composition, structure et stabilité thermique, ceci avant et après utilisation. Pour les trois réactions, les catalyseurs ont montré une sélectivité et une conversion élevées et maintenues dans les conditions de réaction, facilitées par le contenu en métaux catalytiques dont l'activité a été renforcée par les métaux inhérents. La présence de fonctions oxygénées de surface et d'une surface spécifique élevée (<419 m²/g) ont amélioré l'adsorption et la dissociation des gaz réactifs grâce à des sites supplémentaires formés par réduction et à une meilleure activité électronique. Avec ces caractéristiques, les catalyseurs biosourcés ont montré des performances meilleures que celles de catalyseurs références de la littérature en raison d'une meilleure stabilité ou activité catalytiques (conversion maintenue pour plus de 120h, énergie d'activation entre 0.5 et 186 kJ/mol, constante cinétique entre 1.9 x 10^-9 et 4.3 x 10^12. Le catalyseur de saule imprégné au Ni avant pyrolyse et le catalyseur bimétallique (Ni/Fe) de fougère ont montré les meilleures performances pour les réactions de deNOx, et RWGS et WGS, respectivement
This work proposes an innovative approach to the production, characterization and use of biocarbon catalysts for energy and environment-related applications, in order to reduce the cost and impact of the commercial catalysts currently in use. The work developed here promotes a circular economy approach in the way that plants from phytoremediation have been used for the production of eco-friendly biocarbon catalysts. They were used for the production of energy vectors such as hydrogen by direct and reverse water-gas shift reaction (WGS and RWGS respectively), as well as for the decomposition of NOx pollutants (deNOx). Biocarbon catalysts were produced from willow and fern with a controlled metal content introduced by wet impregnation before or after pyrolysis at 800°C to imitate hyperaccumulation (>3 g metal/kg biocarbon) in a porous carbon support. The resulting catalysts were tested in deNOx, as well as WGS and RWGS reactions, and the associated experimental equipments were developed and optimized during this thesis work. They were characterized in terms of composition, structure and thermal stability, before and after use. For the three reactions, the catalysts showed high selectivity and conversion, facilitated by the catalytic metals whose activity was enhanced by the inherent metals. The presence of surface oxygen functions and a high specific surface area (<419 m²/g) improved adsorption and dissociation of reactive gases thanks to additional reactive sites formed by reduction and enhanced electronic activity. With these characteristics, biocarbon catalysts showed better performances than literature-based reference catalysts as they were either more stable or active (conversion maintained for more than 120h, activation energy from 0.5 to 186 kJ/mol, kinetic constant between 1.9 x 10^-9 and 4.3 x 10^12). Willow biocarbon impregnated with Ni before pyrolysis and bimetallic (Ni/Fe) fern biocarbon showed the best performances for the deNOx, and RWGS and WGS reactions, respectively

Resumen
Natural graphite, a type of carbon, is used in most battery driven electronic devices around the world as it serves as the anode in Li-ion batteries. Since 67\% of global production of graphite originates from a single country the EU has classified it as a critical raw material with a high supply risk. If graphite can be produced locally from biomass not only would it potentially make batteries cheaper it could be a huge boon to the Swedish bio industry. In this thesis carbonization of pure lignin is done through hydrothermal carbonization and slow pyrolysis with peak temperature of 900\degree C. The type of carbon needed for these applications involves a high degree of crystallization and large surface areas and pore volumes. Analysis of the samples was done through X-Ray Diffraction, Raman spectroscopy, CHNO- and specific surface analysis. Results show a D/G ratio of 0.85, full width half maximum (FWHM) values of 7.7, which points toward a hard carbon with nano crystalline graphite present in the samples. SSA results show a Brunauer–Emmett–Teller (BET) surface area of around 350 $m^2/g$ and CHNO show a carbon content of about 90\%. The results are promising for use as an anode in hard carbon sodium-ion batteries or for $CO_2$ separation. Techno-economical analysis show that integrated biocarbon production in a bio-ethanol plant is a much more profitable solution than selling the lignin as biofuel or burning it for electricity production.

Resumo: O biochar, biomassa carbonizada por processo de pirólise, foi aplicado na Amazônia, região com diversidade no extrativismo e agricultura, e constituída por exuberante mata espessa com solos bem drenados, pouco férteis e ácidos, com restrita camada de matéria orgânica na sua superfície. Este estudo avaliou a influência do biochar de caroço de açaí (Euterpe oleracea Mart.) como condicionador de solo na produção de mudas de pimenta-do-reino (Piper nigrum L.). O experimento foi conduzido com 17 tratamentos em esquema fatorial 4x4+1, sendo 4 granulometrias combinadas com 4 doses de biochar, mais um controle, com 5 repetições, num delineamento em blocos casualizados. Foram avaliados variáveis no solo e na planta. Os resultados foram submetidos à análise da variância pelo teste F, seguindo-se com a análise de regressão polinomial, quando o teste F foi significativo a no mínimo 5 % de probabilidade. O teste de Tukey foi aplicado para comparação de médias. Observou-se que a inserção do biochar de caroço de açaí possibilitou aumento da atividade enzimática do solo e maior desenvolvimento vegetativo das mudas, sendo a dose de 16 t ha-1 e granulometrias de 5 mm o tratamento recomendado.
Abstract: The biochar, carbonized biomass by pyrolysis process, was applied in Amazonia, a region with diversity in extractivism and agriculture, and constituted by an exuberant thick forest with well drained, little fertile and acidic soils with restricted layer of organic matter in its surface. This study evaluated the influence of açaí lump biochar (Euterpe oleracea Mart.) as a soil conditioner in the production of black pepper (Piper nigrum L.) seedlings. The experiment was conducted with 17 treatments in a 4x4 + 1 factorial scheme, 4 particle sizes combined with 4 doses of biochar and a control, with 5 replications, in a randomized block design. Variables were evaluated in soil and plant. The results were submitted to analysis of variance by the F test, followed by polynomial regression analysis when the F test was significant at least 5 % probability. The Tukey test was applied for comparison of means. It was observed that the insertion of the biochar of the açaí lump allowed to increase the enzymatic activity of the soil and greater vegetative development of the seedlings, being the dose of 16 t ha-1 and particle sizes of 5 mm the recommended treatment.

Resumen
As células a combustível de etanol direto (DEFCs, Direct Ethanol Fuel Cells) são baseadas na eletro-oxidação do etanol à baixa temperatura e necessitam catalisadores à base de metais nobres, devido à cinética mais lenta para as reações de oxi-redução. Entre os catalisadores, a platina e as ligas de platina são os mais utilizados. Materiais para suportar os catalisadores são necessários a fim de reduzir a carga do mesmo empregada. Um dos suportes de catalisadores mais versáteis é o carvão ativado, e um dos mais utilizados tem sido o carvão mineral Vulcan. Recentemente, estudos têm sido realizados sobre a madeira como material precursor de carvão ativado, devido à sua sustentabilidade e também porque os materiais carbonosos obtidos têm excelentes propriedades finais. No presente trabalho, estudou-se a reação de eletro-oxidação do etanol, de catalisadores à base de Pt e PtSn suportados em biocarvões obtidos a partir da madeira Eucalyptus grandis. No início desse trabalho não havia relatos na literatura sobre o uso de carvões ativados obtidos a partir de madeira de Eucalyptus grandis como precursor. Foram utilizados dois métodos de ativação nos suportes, ativação física com CO2 e ativação química com ZnCl2. Os suportes de catalisadores foram caracterizados por análise textural, análise elementar, análise termogravimétrica e por espectroscopia de infravermelho. As técnicas empregadas para a caracterização dos catalisadores foram espectrometria de retroespalhamento de Rutherford (RBS), difração de raios-X (DRX), análise termogravimétrica (TGA), microscopia eletrônica de transmissão (MET), voltametria cíclica (VC) e caracterização espectroeletroquímica (ATR-FTIR in-situ). Os biocarvões apresentaram áreas superficiais maiores e tamanhos de poros menores do que o carvão Vulcan, independente do tratamento. A natureza do suporte influenciou nas características morfológicas dos eletrocatalisadores preparados. Com base nos resultados obtidos os catalisadores suportados nos suportes com ativação química apresentaram os melhores resultados de densidade de corrente para eletro-oxidação do etanol, com exceção do catalisador PtSn suportado no biocarvão ativado fisicamente (PtSn/BCAF). Pode-se dizer que os biocarvões são adequados para aplicações em células de combustível, podendo substituir o uso de suportes baseados em carvões minerais. A eletro-oxidação do etanol nos eletrocataliadores de PtSn nos carvões ativados ocorre principalmente através da produção de acetaldeído e ácido acético.
Direct ethanol fuel cells (DEFC) are based on ethanol electrooxidation at low-temperature and they require noble metal based catalysts, due to the slower kinetic of redox reactions. Among the catalysts, platinum and its alloys have been the most widely used. Catalysts support materials have been employed with the intent to reduce loading catalyst. One of the most versatile catalyst supports is activated carbon, and one of the most widely used is the Vulcan®, a mineral carbon. Currently, different studies have been conducted concerning wood as activated carbon precursor, because of its sustainability and its properties, like suitable porous texture, surface area and surface chemistry. In this work, it was studied ethanol electrooxidation reaction on Pt and PSn catalysts supported on biocarbon. Biocarbons were obtained from Eucalyptus grandis. Literature reports the use of carbon materials as catalyst support, however focused on carbon fibers and carbon nanotubes, without any precedent on the use of activated carbon obtained from Eucalyptus grandis until the start of this work. The carbon supports were obtained by physical activation using CO2, and chemical activation with ZnCl2. Catalyst support characterization boarded elemental analysis, texture analysis, thermogravimetric analysis and infrared spectroscopy. Techniques employed for the catalyst characterization were Rutherford backscattering spectrometry (RBS), X-ray diffraction (XRD), thermogravimetric analysis (TGA), transmission electron microscopy (TEM), cyclic voltammetry (CV) and spectroelectrochemical characterization (ATR-FTIR in situ). Biocarbons presended the higher surface areas and smallest pore size than the Vulcan ones, independent of the treatment. The support nature influenced on the catalyst morphology. Results showed that the catalyst on the chemically activated supports presented the best current density for ethanol electro-oxidation, except for the PtSn on the physically activated biocarbon (PtSn/BCAF). Biocarbons resulted adequate for fuel cell applications and are capable of substituting the conventional supports based on mineral carbon. Ethanol electro-oxidation on PtSn catalysts takes place through the production of acetaldehyde and acetic acid reaction mechanism.

Resumen
La producció de pinya tropical és una activitat econòmica important a Costa Rica, l’àrea de cultiu de la qual ha augmentat significativament en les dues darreres dècades, i amb una significativa generació de residus agroindustrials i ús intensiu de plaguicides com els herbicides bromacil i diuron. Tots dos han estat detectats en aigües superficials i subterrànies, causant problemes ambientals, de salut i econòmics, malgrat que hi ha poca informació sobre el seu destí ambiental en sòls tropicals. La transformació de residus agroindustrials en biocarbó (biochar) mitjançant piròlisi i la seva adició al sòl com a esmena han estat proposats com una pràctica útil per a la gestió de residus que permet la millora de la qualitat del sòl, el segrestament de carboni i una possible mitigació de la mobilitat de plaguicides. L’objectiu de la tesi fou avaluar els beneficis i eventuals efectes no desitjats de l’adició de biocarbó a un sòl costa-riqueny cultivat amb pinya en combinació amb bromacil o diuron, considerant tant els seus efectes en el destí i eficiència com els ecotoxicològics. Els materials carbonitzats (MC) s’obtingueren per piròlisi a 300 o 600 ºC durant una hora, utilitzant com a materials de partida rostoll de pinya tropical (PS), “”pinzote”” de palmera d’oli (PF) i l’endocarp del fruit de café (cascarilla) (CH), que es van caracteritzar fisicoquímicament i es van aplicar al sòl a dosis d’aplicació de 10 i 20 t ha-1. S’avaluà la sorció, la degradació i la biodegradació dels plaguicides en condicions de laboratori, permetent la predicció del seu risc ambiental amb l’índex de classificació d’impacte de plaguicides. Addicionalment, es van avaluar efectes en l’emergència i creixement de d’enciam (Lactuca sativa), el desenvolupament d’invertebrats (el col·lèmbol Folsomia candid i l’enquitreid Enchytraeus crypticus) i la diversitat funcional de la comunitat dels microorganisms (MicrorespTM) per a provar possibles efectes dels MC en l’eficiència dels herbicides i en organismes terrestres no diana. Els MC a 300 ºC es classificaren com a materials torrefactes (MT) i a 600 ºC com a biocarbons (B). Els biocarbons presentaren major superfície específica, contingut de carboni fixe i pH que els MT, alhora que els PS-B i PF-B tenien major abundància de grups oxigenats superficials que CH-B i que tots els MT. Es va demostrar una sorció dèbil al sòl en tots dos plaguicides, fet que suggereix una elevada mobilitat, i la degradació i biodegradació del bromacil fou limitada en comparació al diruon. L’adició de biocarbó incrementà la persistència del bromacil, i els PS-MT i PF-MT la sorció del diuron. No obstant, això no va canviar la mobilitat i toxicitat aquàtica predites pels pesticides. L’adició de MC no reduí l’eficiència dels herbicides, però augmentà l’emergència sense incrementar el creixement. L’aplicació d’herbicides no causà efectes tòxics en col·lèmbols o enquitreids, sinó que promogué la reproducció sense afectar la supervivència. S’observà una evitació generalitzada de les barreges sòl-MC en enquitreids contrària a la preferència dominant en col·lèmbols, independentment de la presència d’herbicides. Finalment, no aparegueren canvis en la diversitat funcional microbiana amb l’adició d’herbicides o MC, llevat de l’increment en la taxa de consum d’alguns substrats en algunes barreges sòl-MC tractades amb diuron. En conclusió, l’adició de MC no canvià l’eficiència dels herbicides ni el seu destí en l’Ultisol tropical argilós estudiat. Sota la gestió habitual del cultiu de la pinya a la regió nord de Costa Rica, tots dos herbicides presentaren un elevat risc ambiental per a aigües superficials i subterrànies, i malgrat que l’adició de MC no ho va mitigar, no van causar efectes negatius sinó una millora del sòl com a hàbitat per a invertebrats edàfics.
La producción de piña es una actividad económica importante en Costa Rica que ha aumentado significativamente su área cultivada en las dos últimas décadas, con una alta generación de residuos agroindustriales y un uso intensivo de plaguicidas, incluidos los herbicidas bromacil y diurón. Ambos se han detectado en aguas superficiales y subterráneas, lo que ha causado problemas ambientales, de salud y económicos, aunque aún existe poca información sobre su destino ambiental en los suelos tropicales. La transformación de residuos agroindustriales en biocarbón (biochar) mediante pirólisis y su adición al suelo como enmienda, se ha propuesto como una práctica útil de gestión de residuos capaz de mejorar la calidad del suelo, el secuestro de carbono y que podría mitigar la movilidad de los plaguicidas. El objetivo de la tesis fue evaluar los beneficios y eventuales efectos no deseados de la adición de biocarbón a un suelo costarricense cultivado con piña en combinación con bromacil o diuron, considerando tanto sus efectos ecotoxicológicos como en su destino y eficiencia. Los materiales carbonizados (MC) se obtuvieron pirolizando a 300 o 600 °C durante una hora rastrojo de piña (PS), pinzote de palma aceitera (PF) y cascarilla de café (CH), se caracterizaron física y químicamente y se mezclaron con suelo en dosis de aplicación equivalentes a 10 y 20 t ha-1. Se evaluaron la sorción, la degradación y la biodegradación de ambos plaguicidas en condiciones de laboratorio con lo que se predijo su riesgo ambiental con el Índice de Clasificación de Impacto de Plaguicidas. Además, se midió la emergencia y el crecimiento de la lechuga (Lactuca sativa), el desarrollo de invertebrados (colémbolo Folsomia candida; enquitréido Enchytraeus crypticus) y la diversidad funcional de los microorganismos (Microresp™) para probar los efectos de los MC en la eficiencia de los herbicidas y sobre organismos terrestres no diana. Los MC a 300 °C se clasificaron como materiales torrefactos (MT) y a 600 °C como biocarbones (B). Los biocarbones mostraron mayor superficie específica, contenido de carbono fijo y pH que los MT, mientras que los PS-B y PF-B presentaron mayor abundancia de grupos funcionales oxigenados superficiales que el CH-B y que todos los MT. Se observó una sorción débil de ambos plaguicidas en el suelo, lo que sugiere una alta movilidad, mientras que la degradación y biodegradación de bromacil fue limitada comparada con el diurón. La adición de biocarbón aumentó la persistencia del bromacil, mientras que los PS-MT y PF-MT aumentaron la sorción del diurón. No obstante, la movilidad y la toxicidad acuática predichas de los herbicidas no se afectaron. La adición de MC no redujo la eficiencia de los herbicidas, pero aumentó la emergencia sin mejorar el crecimiento. La aplicación de herbicidas no tuvo efectos tóxicos sobre colémbolos o enquitréidos pues promovió su reproducción sin afectar la supervivencia. Hubo una evitación generalizada de los enquitréidos de las mezclas suelo-MC opuesta a la preferencia general de los colémbolos, independientemente de la presencia de herbicidas. Finalmente, no se demostraron cambios en la diversidad funcional microbiana por la adición de herbicidas o MC, y solo se observó un aumento en la tasa de consumo de algunos sustratos en algunas mezclas suelo-MC tratados con diurón. En conclusión, la adición de MC no cambió la eficiencia de los herbicidas ni su destino en el Ultisol tropical arcilloso estudiado. Bajo la gestión habitual del cultivo de la piña en la Región Norte de Costa Rica, ambos herbicidas presentaron un elevado riesgo ambiental para aguas superficiales y subterráneas, y pese a que la adición de MC no le mitigar, no causaron efectos negativos sino una mejora del suelo como hábitat para invertebrados edáficos.
Pineapple production is an important economic activity in Costa Rica as shown by the increase in its cropped area in the last two decades. It involves a high generation of agro-wastes as well as an intensive application of pesticides, including the herbicides bromacil, and diuron. Their use is associated with problems of environmental, health and economic concern, because it has been detected in both surface water and groundwater. However, there is still scarce information about the environmental fate of these herbicides in tropical soils. The transformation of this agro-waste surplus by pyrolysis into biochar, a carbonaceous material, followed by its addition to soil as an amendment, has been suggested as a useful waste management practice. This is because it may improve the soil quality and carbon sequestration and potentially mitigate the mobility of pesticides. The aim of this thesis was to evaluate the benefits and unexpected effects of biochar addition to a Costa Rican agricultural soil cropped to pineapple, concurrently considering the effects on bromacil and diuron fate and efficiency as well as non-target soil ecotoxicological effects. For this purpose, pineapple stubble (PS), oil palm fiber (PF) and coffee hulls (CH) were pyrolyzed at 300 or 600 °C for one hour and then physically and chemically characterized. Mixtures of the charred materials (CM) with soil were prepared at application rates equivalent to 10 and 20 t ha-1. Sorption, degradation, and biodegradation of both pesticides were evaluated in the laboratory, and the results were used to predict their environmental risk with the Pesticide Impact Rating Index. In addition, lettuce emergence and growth (Lactuca sativa), invertebrates performance (collembolan Folsomia candida; enchytraeid Enchytraeus crypticus), and microorganism functional diversity (Microresp™) were used to test the effects of CM on the herbicides’ efficiency and on the non-target soil biological groups. CM pyrolyzed at 300 °C were classified as torrefied materials (TM), while those pyrolized at 600 °C were classified as biochars (B). Biochars showed higher specific surface area, fixed carbon content and pH values than TM, while PS-B and PF-B presented a higher abundance of surface oxygenated chemical groups than CH-B and all the TM. A weak sorption of both herbicides to soil was observed suggesting a high mobility, while the degradation and biodegradation of bromacil was more limited compared to that of diuron. The addition of biochars increased the persistence of bromacil, while PS-TM and PF-TM increased the sorption of diuron. Despite that, the predicted mobility and aquatic toxicity of the herbicides were unaffected. The addition of CM did not reduce herbicide efficiency but increased seedling emergence without improving growth. The adding of herbicides had no toxic effects on collembolans and enchytraeids as it promoted their reproduction without affecting survival. A generalized avoidance of CM-mixtures by enchytraeids was observed as opposed to the general preference shown in collembolans, irrespective of the supplementation or not of herbicides. Finally, no changes in the microbial functional diversity by the sole addition of herbicides or CM were demonstrated, and a significant increase in the consumption rate of some substrates was observed only in some diuron-treated CM-mixtures. In summary, the addition of CM did not change the efficiency of the herbicides nor their fate in a tropical clay Ultisol. Under pineapple cropping conditions of the northern region of Costa Rica, bromacil and diuron presented a high estimated environmental risk to surface water and groundwater, and the addition of CM did not change this risk. Simultaneously, no negative effects to the soil ecosystem were observed, but there was an improvement in soil as a habitat for some soil invertebrates.

As florestas nativas são muito exploradas devido à crescente demanda de madeira e seus derivados para suprir o mercado consumidor, deixando evidente a importância das florestas plantadas como recurso para suprir a demanda comercial. O Pinus é uma espécie que se destaca devido a sua adaptabilidade aos mais diversos ambientes brasileiros. As indústrias beneficiadoras da matéria-prima para geração de madeira se caracterizam por gerar grande quantidade de resíduos denominados de “serragem”, muitas vezes sem destinação. O objetivo desta pesquisa foi de gerar biochar através do processo de pirólise em diferentes temperaturas: 300º, 400º, 500º e 600ºC utilizando serragem de pinus spp. e avaliar sua incorporação ao solo na forma de substrato para germinação e desenvolvimento de mudas. Os biochar foram caracterizados quanto ao rendimento por pirólise e determinados seus teores de cinzas e carbono fixo segundo a norma ABNT NBR 8112/86. Todos os dados analisados desde a granulometria, caracterização físico-química, análises de germinação e o índice de qualidade de mudas através da metodologia de DICKSON, foram submetidos à analise estatísticas por teste de confrontamento de médias Tukey a 5% de probabilidade. Pode-se concluir que houve diferença significativa nos tratamentos que foram incorporados biochar, comprovando estatisticamente que o BC400, BC500 e BC600 obtiveram os melhores resultados o que também foi confirmado pelo índice de qualidade de mudas (IQD); não houve diferença entre nenhum tratamento com relação à quantidade de biochar e/ou serragem incorporada ao solo.
Native forests are overexploited due to growing demand for wood and its derivatives to meet the consumer market, making it clear the importance of planted forests as a resource to meet the commercial demand. The pine is a species that stands out because of its adaptability to the most diverse Brazilian environments. The beneficiary industries of the raw material for the generation of wood are characterized by generating large amounts of waste called "sawdust", often without destination. The objective of this research was to generate biochar through pyrolysis process at different temperatures: 300, 400th, 500th and 600 ° C using spp pine sawdust. and evaluate its incorporation into the soil as substrate for germination and seedling development. The biochar were characterized in terms of yield determined by pyrolysis and their ash content and fixed carbon according to ABNT NBR 8112/86. All data from the analyzed particle, physicochemical characterization, analysis germination and seedling quality index through Dickson method, were subjected to statistical analysis by means confronting Tukey test at 5% probability. It can be concluded that there was significant difference in treatments which were incorporated into biochar, proving that statistically BC400, BC500 and BC600 obtained the best results which was also confirmed by the changes of quality index (DCI); there was no treatment difference with respect to the amount of biochar and / or sawdust incorporated into the soil.
