Mismanagement during postharvest handling of cassava can degrade the quality of the product and depreciate its selling price considerably. This study proposed the feasibility of using RGB-depth camera to measure the quality of cassava roots in a non-destructive, fast and cost-effective manner. Methodology to estimate the volume of cassavas Kasetsart 50 variety was the focus of this study. Using RGB-D images collected from 60 cassava samples with each one being photographed from 6 different orientations. Image Processing model and Point Cloud image model were used to find the volume from depth images, and then disk method and box method were used to estimate the volume of cassava under ellipsoidal shape. Both estimation methods provided usable values for the volumes in the range of 100 - 500 ml with RMSE values of 5.91% and 4.02%, respectively. The estimated volume can be applied to find density to predict the rotten cassava for improving quality and efficiency of cassava industry.

Full textAbstract:
The food business opportunity is very interesting for home industry entrepreneurs in West Sumatra, a home industry of cassava chips. The step of the cassava chip production process that takes longer time than the other step is the washing process. The cassava washing process is carried out manually because washing device that uses motor drives are not affordable for home industry entrepreneurs. In addition, the cassava washing process makes a physical complaint from the operators. Therefore, this research designs a cassava washer that is affordable for the home industry by considering design methods, ergonomic aspects, and customers' needs. This design is carried out using the Quality Function Deployment (QFD) method to translate the voice of the customer into technical and design characteristics, morphological charts for generating alternative designs, and an objective weighted method for evaluating that alternative. The result of this research is the design of a cassava washer which is more practical because it makes the operator works easier and can save time in the washing process. It is also very affordable, with an estimated cost of production IDR2,397,743.

The increasing consumption of water and the legal requirements for sustainable use of water resources is seen as a universal concern. The production of cassava starch uses large volumes of water and consequently generates significant amounts of wastewater that require proper treatments for their reuse or discharge to the environment. Most of the research for the treatment of effluents from cassava processing companies is done with anaerobic digestion. The aim of this paper was to evaluate an innovative process for organic load reduction of cassava wastewater, through oxidation processes with hydrogen peroxide, ozone and ultraviolet radiation. For the development of the tests, we used a photoreactor with a volume of 6.2 liters with two UV lamps with 75W, an ozone generator with capacity of 10g O3 h-1 and hydrogen peroxide solution - 50 % (w/w). Assays were performed in acidic and alkaline medium, with a treatment time of 420 minutes. The substrate used was collected in cassava processing company and went through processes of sedimentation and filtration before the testing. These processes provided reduction of organic matter higher than 50%. The dosage of hydrogen peroxide was determined by the COD. The test with hydrogen peroxide and ultraviolet radiation in alkaline medium provided reduction of 50.1% organic matter (with pH 7.0 and H2O2/COD ratio equal to 3). In an acidic medium, the efficiency was 92.1 % (pH 2.4 and H2O2/COD ratio equal to 3). The ozone test with no ultraviolet radiation in alkaline promoted reduction of 66.0 % (pH 11.0 and ozone dosage equal to 1.49 g h-1). The test with ozone and ultraviolet radiation in acid medium promoted reduction of 41.8 % (pH 6.6 to ozone dosage equal to 1.49 g h-1). The test with ozone and ultraviolet radiation in alkaline medium promoted reduction of 80.8 % (pH 10.5 and ozone dosage equal to 1.98 g h-1). The test with hydrogen peroxide, ozone and ...

The present study aimed to evaluate the correlation between the physical characteristics of the soil, promoted by different tillage, and the qualitative and quantitative agronomic traits and physiologic indexes of cassava pla nt and identify at what time of plant development these correlations imply in possible differences in agronomic components. A field experiment was carried out in a randomized block split plot design with six replications. The types of tillage (minimum till age, conventional tillage and no tillage) were considered main plots and the times of evaluation, the subplots. The results, except for physiological indexes, were subjected to analysis of variance at 5% level of probability by F test, the treatments were compared by t test at 5% probability and times of evaluation were compared by regression. Additionally, all parameters were correlated by the Pearson coefficient.

For the development of the tests, we used a photoreactor with a volume of 6.2 liters with two UV lamps with 75W, an ozone generator with capacity of 10g O3 h-1 and hydrogen peroxide solution - 50 % (w/w). Assays were performed in acidic and alkaline medium, with a treatment time of 420 minutes. The substrate used was collected in cassava processing company and went through processes of sedimentation and filtration before the testing. These processes provided reduction of organic matter higher than 50%. The dosage of hydrogen peroxide was determined by the COD. The test with hydrogen peroxide and ultraviolet radiation in alkaline medium provided reduction of 50.1% organic matter (with pH 7.0 and H2O2/COD ratio equal to 3). In an acidic medium, the efficiency was 92.1 % (pH 2.4 and H2O2/COD ratio equal to 3). The ozone test with no ultraviolet radiation in alkaline promoted reduction of 66.0 % (pH 11.0 and ozone dosage equal to 1.49 g h-1). The test with ozone and ultraviolet radiation in acid medium promoted reduction of 41.8 % (pH 6.6 to ozone dosage equal to 1.49 g h-1). The test with ozone and ultraviolet radiation in alkaline medium promoted reduction of 80.8 % (pH 10.5 and ozone dosage equal to 1.98 g h-1). The test with hydrogen peroxide, ozone and ...

Resumo: Essa pesquisa teve como objetivo avaliar as características fisiológicas, bioquímicas e os componentes da produção da mandioca de mesa IAC 576-70 sob deficiência hídrica em diferentes fases fenológicas da cultura. O experimento foi conduzido em cultivo protegido, em delineamento inteiramente casualizado e esquema fatorial 3x3, constituído por três fases fenológicas (de 90 a 180; de 180 a 270 e de 270 a 360 dias após o plantio, DAP) e três tensões de água no solo (-10, -40 e -70 kPa), com cinco repetições. As manivas-sementes foram plantadas em caixas com 0,30 m3 de solo e a umidade do solo foi monitorada por tensiômetros, mantendo-se o solo na capacidade de campo até o início dos tratamentos. As características fisiológicas e bioquímicas foram descritas apenas na fase de 90 a 180 DAP, pois a perda natural de folhas no período do inverno na região comprometeu as avaliações nas demais fases. Aos 135 DAP a deficiência hídrica aumentou 42,9% o teor de clorofila total nas plantas sob tensão de -70 kPa. O potencial da água, o teor relativo de água e o extravasamento de eletrólitos nas folhas não foram alterados pelas tensões de água no solo. Houve acréscimo de 16,0% na densidade estomática foliar nas tensões de -40 e -70 kPa, enquanto que a eficiência quântica efetiva do fotossintema II e a taxa de transporte de elétrons foram reduzidas. As plantas sob as menores tensões de água no solo aumentaram 15,4% os teores de açúcares solúveis nas folhas. As atividades das enzimas antioxidan...

Abstract: This research aimed to evaluate the physiological and biochemical characteristics and yield components of sweet cassava plants IAC 576-70 under water deficit in different phenological phases of the crop. The experiment was carried out in a completely randomized design and factorial scheme 3 x 3, consisting of three phenological stages (90 to 180, 180 to 270 and 270 to 360 days after planting DAP), and three soil water tension (-10, -40 and -70 kPa), with five replicates. The stem cuttings were planted in boxes with 0.30 m3 of soil and the soil moisture was monitored by tensiometers, keeping the soil in the field capacity until the beginning of the treatments. The physiological and biochemical characteristics were described only in the phenological phase 90 to 180 DAP, because the natural loss of leaves in the winter period in the region compromised the evaluations in the other phases. At 135 DAP the water deficit increased by 42.9% the total chlorophyll content in plants under tension of -70 kPa. The water potential, relative water content and electrolyte leakage in the leaf were not altered by soil water tension. There was an increase of 16.0% in leaf stomatal density under tensions of -40 and -70 kPa, while the effective quantum efficiency of photosystem II and the rate of electron transport were reduced. The plants under the tensions of -40 and -70 kPa increased the soluble sugar content of the leaves by 15.4%. The activities of antioxidant enzymes were more accentuated at...

In dairy farming, one of the factors that raise the cost of production is feed, which can reach 70% of the total cost. With this, it is necessary to look for alternatives to reduce these costs without sacrificing productivity. An alternative is to enrich food resources of the animals, through the use of byproducts of industrial manioc starch. These alternative foods may constitute an interesting strategy, because in addition to being acquired by a low commercial value, may have high energy content and can also give an appropriate final destination byproduct of the cassava industry, contributing to the environment. The residue obtained during the processing of cassava has moisture content between 75% and 85%. The animal productivity can be affected negatively, depending on consumption and digestibility of nutrients. This study aimed to evaluate the chemical, microbiological, and detect the presence of mycotoxins in moist residue cassava starch (RMCS), and to evaluate the influence of five levels RMCS on intake and digestibility of nutrients, production and composition milk, and some blood parameters in dairy cows, Holstein, with average initial production of 30.65 kg milk / day. We observed a significant reduction in consumption (EE), and a linear effect for all nutrients studied, except for crude protein. Milk production was negatively affected, with a reduction to include RMCS. The chemical composition of RMCS did not change during storage, only significant variation in dry matter (DM). For populations of microorganisms, there was a significant increase only fungi and yeasts. Zearalenone levels were detected in 100% of the samples analyzed RUFM. The milk was reduced, but the efficiency of feed conversion was not affected, indicating that the residue can be used, however, it is necessary to adjust the levels of inclusion of the diet. The storage of RMCS proved effective under the conditions studied, since there were no changes in the nutritional value of the residue, but high counts of yeasts and fungi, and mycotoxins, may suggest that the material has a high risk of degradation
Na atividade leiteira, um dos fatores que elevam os custos da produção é a alimentação animal, que podem chegar a 70% do custo total. Com isso, é necessário buscar alternativas para redução desses custos, sem prejudicar a produtividade. Uma alternativa é o enriquecimento dos recursos alimentícios dos animais, através da utilização de subprodutos da indústria de fécula de mandioca. Esses alimentos alternativos podem constituir uma estratégia interessante, pois, além de serem adquiridos por um baixo valor comercial, podem apresentar alto teor energético, podem também, dar um adequado destino final ao subproduto da fecularia, contribuindo para preservar o meio ambiente. O resíduo obtido durante o processamento da mandioca apresenta teor de umidade entre 75% e 85%. A produtividade animal pode ser afetada de forma negativa, dependendo do consumo e da digestibilidade dos nutrientes da dieta. Esta pesquisa tem por objetivo avaliar a composição química, microbiológica, e também detectar presença de micotoxinas no resíduo úmido de fécula de mandioca (RUFM), além disso, avaliar a influência de cinco níveis de RUFM sobre o consumo e digestibilidade dos nutrientes, produção e composição do leite, e alguns parâmetros sanguíneos de vacas em lactação, da raça Holandesa, com produção média inicial de 30,65 kg de leite/dia. Nesta pesquisa observou-se a redução significativa no consumo de extrato etéreo (EE), e o efeito linear negativo para todos os nutrientes estudados, exceto para a proteína bruta. A produção de leite foi influenciada de forma negativa, ocorrendo redução com a inclusão de RUFM. A composição química do RUFM não sofreu alterações durante a estocagem, houve variação significativa apenas nos teores de matéria seca (MS). Para as populações de microrganismos, houve elevação significativa apenas de fungos e leveduras. Níveis de Zearalenona foram detectados em 100% das amostras de RUFM analisadas. A produção de leite sofreu redução, mas a eficiência na conversão alimentar não foi alterada, mostrando que o resíduo pode ser utilizado, no entanto, é necessário adequar os níveis de inclusão deste na dieta. A estocagem do RUFM mostrou ser eficiente nas condições estudadas, pois não houve alterações no valor nutricional do resíduo, porém, altas contagens de fungos e leveduras, e a presença de micotoxinas, podem sugerir que o material tenha alto risco de degradação

This research aimed to study the treatment of manipueira by combined process of coagulation/flocculation and membrane separation, targeting the non-potable reuse this water. For pretreatment of the effluent triage was performed using five natural coagulants (Acquapol WW, and S5T Tanfloc POP, ST, SG), a chemical (Al2SO4) and a cationic flocculant (Zetag ® 8185).Experimental designs Plackett & Burman (PB12) followed by a full factorial 2k was used in order to obtain the best experimental conditions in the process. The supernatant obtained in step of coagulation/flocculation under went a process of separation of micro-and ultrafiltration membranes varying pressures (0,6, 1 and 1,4 bar), permeate flows being analyzed, fouling and removal efficiency.The raw sewage and water resulting from treatment in the best conditions of coagulation/flocculation and filtration, under went a toxicity test using brine shrimp body. From the selected sorting the sedimentation time 15 minutes and Tanfloc POP among the natural coagulants.The best condition of operation of the coagulation/flocculation obtained through experimental planning was 1 min to 10 min, TMR TML, 180 rpm for VMR and 10 rpm of VML, pH of 8.5 and coagulant concentration of 440 mg L-1, with removals of 88,5% to turbidity and 78,9% color. The model adjusted to the data in the color parameter removal complete factorial planning using coagulant Tanfloc POP. The tests of filtration (MF and UF) presented on pressure of 1,4 bar, above 95% removal of colour and turbidity, and above 60% for nitrogen and COT, but with lower COD removal (less than 70%). The toxicityof that treated wastewater (66% and 100%) reported toxic to the test organism due to the presence of free cyanide. The permeated obtained (MF) could be used for less noble purposes among the classes (2, 3 and 4) suggested by the ABNT NBR 13,696/1997. The results obtained in this study demonstrate the potential of C/F, MF and UF, for treatment of manipueira.
Esta pesquisa teve como objetivo estudar o tratamento da manipueira por processo combinado de coagulação/floculação e separação por membranas, visando o reuso não potável desta água. Para o pré-tratamento do efluente foi realizada uma triagem utilizando cinco coagulantes naturais (Acquapol WW, S5T e Tanfloc POP, ST, SG), um químico (Al2SO4) e um floculante catiônico (Zetag 8185®). Planejamentos experimentais Plackett & Burman (PB12) seguido de um fatorial completo 2k foram utilizados a fim de obter as melhores condições experimentais no processo. O sobrenadante obtido na etapa de coagulação/floculação foi submetido a um processo de separação por membranas de micro e ultrafiltração variando-se as pressões (0,6, 1 e 1,4 bar), sendo analisados os fluxos de permeado, fouling e eficiência de remoção. O efluente bruto e a água resultante do tratamento nas melhores condições dos ensaios de coagulação/floculação e filtração, foram submetidos a um ensaio de toxicidade utilizando o organismo Artemia salina. A partir da triagem selecionou-se o tempo de sedimentação de 15 minutos e o Tanfloc POP dentre os coagulantes naturais. A melhor condição de operação da coagulação/floculação obtida através dos planejamentos experimentais foi de 1 min para TMR, 10 min de TML, 180 rpm para VMR e 10 rpm de VML, pH de 8,5 e concentração do coagulante de 440 mg L-1, com remoções de 88,5% para cor e 78,9% de turbidez. O modelo ajustou-se aos dados de remoção do parâmetro cor no planejamento fatorial completo utilizando o coagulante Tanfloc POP. Os ensaios de filtração (MF e UF) apresentaram na pressão de 1,4 bar, remoções acima de 95% de cor e turbidez, e acima de 60% para nitrogênio e TOC, porém com baixa remoção de DQO (menor que 70%). A toxicidade, do efluente mesmo tratado (66% e 100%) apresentou-se tóxico para o organismo teste devido à presença de cianeto livre. O permeado obtido (MF) poderia ser utilizado para fins menos nobres dentre as classes (2, 3 e 4) sugeridas pela ABNT NBR 13.969/1997. Os resultados obtidos neste estudo demonstram o potencial dos processos de C/F, MF e UF, para tratamento da manipueira.

Full textAbstract:
O estudo tem como objetivo diagnosticar a competitividade da cadeia de produção agroindustrial de fécula de mandioca, enfatizando o segmento de produção de matéria-prima e os determinantes do processo de inovação tecnológica. Especificamente, pretende-se identificar quais as principais restrições para melhorar a competitividade da cadeia; calcular um indicador de competitividade que relacione as variações de preços do produto e dos insumos, assim como as decisões estratégicas de políticas públicas e privadas; determinar como os investimentos em tecnologia têm influenciado os níveis de competitividade do segmento agrícola e identificar quais fatores explicam e determinam a trajetória tecnológica implementada na cadeia. Para atingir esses objetivos, utilizou-se um instrumental que permite realizar predições quantitativas dos efeitos da adoção de políticas públicas e de decisões gerenciais internas às firmas que atuam na cadeia. Essas predições foram baseadas num indicador de competitividade fundamentado no conceito de quase-renda, o qual foi estimado por meio de um modelo lógite ordenado. No estudo dos aspectos relacionados à tecnologia, além das abordagens que privilegiam os sinais de mercados, utilizaram-se aquelas que reconhecem a importância do caráter sistêmico e interdependente dos fatores determinantes da decisão de inovar. Com base nos resultados, pode-se concluir que a cadeia ainda não está suficientemente capacitada e organizada para transformar as potencialidades identificadas em verdadeiras oportunidades de mercado. Têm concorrido para isso a trajetória tecnológica seguida e o desempenho econômico observado no segmento agrícola. Esse segmento apresentou-se marginalmente competitivo, ou seja, a quase-renda gerada não foi suficiente para remunerar os fatores de produção específicos, utilizados no processo de produção, pelo menos no nível do custo de oportunidade considerado. Os principais fatores e condicionantes que estão restringindo a competitividade relacionam-se aos aspectos do lado da demanda; a limitações tecnológicas, tanto do segmento agrícola como do de processamento e a fatores estruturais e sistêmicos. As possibilidades de melhorar a competitividade vinculam-se a ações do lado da receita, ou seja, aumentos na produtividade média e/ou nos preços. Embora a capacidade de os produtores intervirem, de forma isolada, na trajetória dos preços seja mais remota, os resultados alcançados sinalizam que a variável preço assuma maior relevância no processo. Portanto, as políticas que reduzem a instabilidade nos preços são as mais seguras como estratégia de intervenção. Nesse sentido, a adoção de relações mais harmoniosas, que valorizem a forte dependência entre os elos da cadeia, promoverá ganhos competitivos. Quanto aos determinantes da trajetória tecnológica, destacam-se: as características intrínsecas da cultura, que lhe conferem rusticidade e adaptabilidade a condições ambientais adversas; a possibilidade de utilizar fatores de produção de baixo custo de oportunidade; o grau de apropriabilidade dos retornos dos investimentos em geração de tecnologia; o fato de ser uma cultura sobre a qual a quantidade de pesquisa ainda é relativamente baixa; os limites impostos pelo paradigma tecnológico vigente; o nível de demanda interna por mandioca e derivados, que ainda vem sendo atendido por uma oferta praticamente associada aos sistemas de produção tradicionais e a inexistência de grupos de interesse vinculados ao setor mandioqueiro.This study is aimed at determining the cassava starch agro-industrial production chain competitiveness with special attention to the raw material production segment and the factors leading to technological innovation processes. It is specifically intended to identify the main constraints on gains in the production chain competitiveness, to compute a competitiveness index which relates the products price and the production costs, as well as public and private policy strategies, to determine how investments in technology have influenced the agricultural segment competitiveness, and to identify which factors explain and determine the production chain technological background. In order to meet these objectives, we used tools that allow quantitative predictions to evaluate the effects of public policies and companies internal managerial decisions. Such predictions were based on a competitiveness index underpinned by the quasi-rent concept computed through an ordered logit model. In the study of the technological aspects, besides the approaches that are based mainly on market signals, we considered the systemic and interdependent importance of factors leading to the decision to innovate. Results show that the production chain is not sufficiently able and organized to change the identified potentialities into real market opportunities, and the technological trajectory and economic performance of the agricultural segment have contributed to such a panorama. The agricultural segment showed to be marginally competitive, that is, the quasi-rent generated did not offset specific production factors, at least at the opportunity cost level considered. The main factors and conditions restricting competitiveness are related to characteristics related to the demand side, to technological constraints, not only in the agricultural segment, but also in processing, and to structural and systemic factors. Potential improvements in competitiveness are linked to actions on the revenue side, that is, in average productivity and/or prices. Although the possibility of individual growers interfering in price trajectories is remote, results indicate that the variable price should have greater relevance in the process. Therefore, policies that reduce price instabilities are the safest intervention strategies. Consequently, the adoption of more harmonious relationships, which value a strong interdependence of the chain links, will generate gains in competitiveness. The technological trajectory determining factors that stand out are the crops intrinsic characteristics of rusticity and adaptability to adverse environmental conditions, the possibility of using production factors of low opportunity cost, the suitable payoff level of investments in technology, the relatively little research carried out on the crop, the limits imposed by the technological paradigm, the standard domestic demand for cassava and its by-products, which has been satisfied by a supply almost completely associated to traditional production systems, and the non-existence of interest groups linked to the cassava sector.

The pollution by synthetic dyes from the dyeing process has seriously damaged the aquatic biota of receivers bodies, requiring thus, efficient and inexpensive alternatives to remove these contaminants before they are released to the environment. An alternative method is adsorption using agro industrial biomass as adsorbents, which besides removing of the environmental dyes have the advantage of the reuse of waste that would be discarded. In this work, the sheath peach palm and cassava peel, both in its form in nature and chemically treated, were studied as its adsorption capacity of reactive blue dye 5G. The characterization of the samples was realized using MEV and spectroscopy in infrared region which identified the presence of carboxylic groups, hydroxyl and carbonyl in both materials. Was also evaluated from the TGA the thermal behavior of the samples, it can noted three stages of degradation: Moisture removal, decomposition of hemicellulose, cellulose and lignin. The kinetic test showed a equilibration time of 20 to 200 minute for cassava biomass of cassava in nature and modified, respectively. For biomass from peach palm the adsorption equilibrium time was from 600 minutes for both adsorbents. The model of pseudo-second order was the that best fit to the experimental data for both, however, the peach palm in nature also follows a kinetics described by intra-particle diffusion model. The experimental data obtained in equilibrium test were adjusted to Freundlich isotherm model, suggesting that the removal of the dye is based in a multilayer adsorption on the surface of the adsorbents. The maximum biosorption capacity was 21.3 mg g-1 for modified cassava biomass and 21.4 mg g-1 for biomass from peach palm in nature. Both adsorbents when applied in industrial effluent showed good efficiency in removal of this dye in aqueous medium. Thus, aiming at industrial application, it becomes feasible work with the biomass of peach palm and cassava in nature form, due to its low cost of implementation and not generate new waste resulting from the modification. Thus, the use of sheath of peach palm and cassava to be a alternative for the adsorption of the dye reactive blue 5G in aqueous effluents.
A poluição por corantes sintéticos oriundos do processo de tingimento tem danificado seriamente a biota aquática dos corpos receptores, necessitando assim de alternativas eficientes e baratas que removam esses contaminantes antes que sejam lançados ao meio ambiente. Um processo alternativo é adsorção utilizando biomassas agroindustriais como adsorventes, que além de removerem os corantes do ambiente possuem como vantagem o reaproveitamento de resíduos que seriam descartados. Neste trabalho, a bainha do palmito pupunha e a casca de mandioca, ambos em sua forma in natura e quimicamente tratados, foram estudados quanto a sua capacidade de adsorção do corante azul reativo 5G. A caracterização dos materiais foi realizada utilizando MEV e espectroscopia na região do infravermelho a qual identificou a presença de grupos carboxílicos, hidroxila e carbonila em ambos materiais. Também foi avaliado a partir do TGA o comportamento térmico das amostras, o qual observou três estágios de degradação: remoção da umidade, decomposição da hemicelulose, celulose e lignina. O teste cinético apresentou um tempo de equilíbrio de 20 e 200 minutos para a biomassa de mandioca in natura e modificada, respectivamente. Para a biomassa do palmito pupunha o tempo de equilíbrio de adsorção foi a partir de 600 minutos para ambos adsorventes. O modelo de pseudo-segunda ordem foi o que melhor se ajustou aos dados experimentais, entretanto, para o palmito in natura segue-se também uma cinética descrita pelo modelo de difusão intra-particula. Os dados experimentais obtidos no teste de equilíbrio foram ajustados ao modelo isotérmico de Freundlich, sugerindo que a remoção do corante baseia-se em um processo de adsorção de multicamadas sobre a superfície dos adsorventes. A capacidade máxima de biossorção foi de 21.03 mg g-1 para a biomassa de mandioca modificada e 21.43 mg g-1 para a biomassa do palmito pupunha in natura. Todos os materiais quando aplicados ao efluente industrial bruto demonstraram boa eficiência na remoção do corante presente em meio aquoso. Assim, visando à aplicação industrial, torna-se viável trabalhar com as biomassas de palmito e mandioca em sua forma in natura, devido seu baixo custo na aplicação e não geração de novos resíduos oriundos da modificação. Desta forma, a utilização da bainha do palmito pupunha e da casca de mandioca mostrou ser uma alternativa promissora para a adsorção do corante azul reativo 5G em efluentes aquosos.

AbstractIn Nigeria, processing cassava for food and industry yields around 15 million tons of wet peels annually. These peels are usually dumped near processing centres to rot or dry enough to be burned. Rotting heaps release methane into the air and a stinking effluent that pollutes nearby streams and underground water, while burning produces clouds of acrid smoke. However, when properly dried, peels can be an ingredient in animal feed. Previous attempts over two decades to use peels in animal feed failed to yield profitable options for drying wet peels at commercial scale, but recent research suggests that cassava peels can be processed into high-quality cassava peel (HQCP) products to be used as nutritious, low-cost animal feed ingredients. The core innovation was to adopt the same steps and equipment used for processing cassava roots into gari, the main staple food in the country. When dried, 3 tons of wet peels yield a tonne of healthy and energy-rich animal feed, containing nearly 3,000 kilocalories per kilogram of dry matter (kcal/kgDM). Adopting this innovation at scale in Nigeria’s poultry and fish sectors alone has the potential to turn approximately 3.6 million tons of wet peels into 1.2 million tons of feed ingredients capable of replacing approximately 810,000 tons of largely imported maize. The innovation has great potential to increase feed availability and lower its cost while saving cereals for human consumption, reducing the import bill, creating new business opportunities, and protecting the environment. This research was initiated by CGIAR centres and taken up by the CGIAR Research Program on Roots, Tubers and Bananas (RTB) over the past decade with strategic input from the CGIAR Research Program on Livestock to accelerate development of the innovation, and this chapter documents the potential and progress in taking this innovation to scale.

Full textAbstract:
Cassava is an important food security and industrial crop. Its production is constrained by viral diseases such as cassava mosaic disease (CMD) and cassava brown streak disease (CBSD), caused by cassava mosaic begomoviruses (CMBs) and ipomoviruses, respectively. In recent years, CMBs have been associated with satellite DNAs. Food security status of cassava coupled with high demand for cassava as feed and industrial uses has been the driving force for scientists and the research community in Africa and beyond. In this review, cassava production, uses of cassava, production constraints, begomoviruses, satellite DNAs, Bemisia tabaci, cassava mosaic disease (CMD), Cassava brown streak virus (CBSV), current and future efforts in cassava production and research are discussed. This was done in an effort to create a knowledge pool that can promote cassava food security status and mitigate disease and yield loss.

Full textAbstract:
Breakthrough innovations can spur growth in the modern era industry to realise sustainability and high returns on investments. Nowadays, biobased innovations for application in diverse industry sectors are considered as future pillars to counter resource depletion and ensure positive environmental impacts. Cassava is a strong flagship biomaterial promoting solution for resource-efficient use and green environment. Innovative industrial application of cassava biomaterials enriches literature, presenting cassava as a versatile and unrivalled crop that is cardinal for more sustainable environment and biodegradable industrial products. Work on novel cassava biomaterials, which are low-cost, unexploited and with zero competition for food supply, are included. Using an integrated sustainable process, it shows how to indirectly reduce waste streams, through their effective use, guaranteeing zero carbon footprints and acting as a non-traditional strategy for equilibrium atmosphere and active packaging systems. Applications of Cassava biomaterial in food, as food supplements and in packaging systems are also covered in this chapter.

Full textAbstract:
Cassava is a good source of carbohydrates and a staple diet in many countries. It has a high-calorie count but a low protein and fat content. Microalgae biomass is increasingly being used in the food business industry due to its ease of production, low carbon requirements, and small footprint. The usage of microalgae in combination with cassava is becoming more common as it can boost the amount of nutrients in processed cassava products. In this chapter, we discuss the development of cassava products that combine cassava with microalgae. Furthermore, cassava waste contains carbohydrates, which can be used as a carbon source for the development of microalgae. Cassava starch, when modified to become cationic cassava starch, has the potential to be used as a flocculant agent for the separation of microalgal biomass. Cassava starch is also well-known for being a low-cost source of bioplastics. This chapter also addresses the possibilities for microalgae and cassava to be used as bioplastics in the same way.
