Present status and potentials of inshore and offshore pelagic fisheries in the capture and processing industries of Nigeria

Apart from activities of some foreign-based vessels, commercial exploitation of pelagic fishery resources in Nigeria has been limited to inland and inshore waters. Estimated potential for the inshore pelagic fishery is 70,000-90,000 tonnes while the small pelagic resources in the near offshore as well as tuna and tuna-like fishes further offshore have potentials of about 10,000 metric tonnes each. Despite the abundance of tuna within and adjoining the Nigerian EEZ, and its importance in the international market, only foreign-flagged vessels take advantage. In addition, the inshore pelagic fisheries in Nigeria have for long remained underexploited. The most common processing method has remained the age-old traditional smoke-drying, which is inadequate resulting in colossal waste through denaturation and incessant infestations by insects and moulds among other causes. The use of modern smoking techniques coupled with effective distribution systems can undoubtedly reduce waste. However, these are often not within the reach of most artisanal processors. It is proposed that the organised private sector should invest on simple but proven processing equipment such as smoking kilns. The inshore pelagic fish species and other small fishes can sustain cottage canning industries sited in fishing villages/settlements while larger canning factories should be based on offshore resources. Modalities for successful investments are highlighted, while a major consideration is given to joint ventures

Development of solar air heaters & thermal energy storage system for drying applications in food processing industries

In the present work, the author has designed and developed all types of solar air heaters called porous and nonporous collectors. The developed solar air heaters were subjected to different air mass flow rates in order to standardize the flow per unit area of the collector. Much attention was given to investigate the performance of the solar air heaters fitted with baffles. The output obtained from the experiments on pilot models, helped the installation of solar air heating system for industrial drying applications also. Apart from these, various types of solar dryers, for small and medium scale drying applications, were also built up. The feasibility of ‘latent heat thermal energy storage system’ based on Phase Change Material was also undertaken. The application of solar greenhouse for drying industrial effluent was analyzed in the present study and a solar greenhouse was developed. The effectiveness of Computational Fluid Dynamics (CFD) in the field of solar air heaters was also analyzed. The thesis is divided into eight chapters.

Valorization of date palm (Phoenix dactylifera) fruit processing by-products and wastes using bioprocess technology – Review

The date palm Phoenix dactylifera has played an important role in the day-to-day life of the people for the last 7000 years. Today worldwide production, utilization and industrialization of dates are continuously increasing since date fruits have earned great importance in human nutrition owing to their rich content of essential nutrients. Tons of date palm fruit wastes are discarded daily by the date processing industries leading to environmental problems. Wastes such as date pits represent an average of 10% of the date fruits. Thus, there is an urgent need to find suitable applications for this waste. In spite of several studies on date palm cultivation, their utilization and scope for utilizing date fruit in therapeutic applications, very few reviews are available and they are limited to the chemistry and pharmacology of the date fruits and phytochemical composition, nutritional significance and potential health benefits of date fruit consumption. In this context, in the present review the prospects of valorization of these date fruit processing by-products and wastes’ employing fermentation and enzyme processing technologies towards total utilization of this valuable commodity for the production of biofuels, biopolymers, biosurfactants, organic acids, antibiotics, industrial enzymes and other possible industrial chemicals are discussed

Processo alternativo de catch-up em indústrias intensivas em recursos naturais: uma análise empírica da trajetória tecnológica da indústria de bioetanol de cana-de-açúcar no Brasil

Esta tese diz respeito ao desenvolvimento tecnológico e inovação em indústrias intensivas em recursos naturais no contexto de economias emergentes. A tese explora como a acumulação de capacidades tecnológicas e os mecanismos de aprendizagem influenciaram a trajetória tecnológica na indústria de bioetanol de cana-de-açúcar no Brasil, durante o período de meados da década de 1970 a 2014. Muito se avançou na compreensão do processo de catch-up tecnológico de empresas e indústrias de economias emergentes. Contudo, essas pesquisas geralmente exploram o processo de catch-up tecnológico relacionado às trajetórias tecnológicas já mapeadas pelos líderes mundiais em indústrias de manufatura e transformação. Parte desses estudos ignora que o desenvolvimento de atividades industriais poderia ocorrer em indústrias intensivas em recursos naturais. Além disso, indústrias intensivas em recursos naturais são geralmente encapsuladas como commodities e low-tech, caracterizadas por uma limitada oportunidade de aprendizagem tecnológica e acumulação de capacidades tecnológicas. Entretanto, o processo de industrialização em indústrias intensivas em recursos naturais em regiões como a América Latina ainda é pouco compreendido e são escassas as pesquisas que investigam o processo de catch-up tecnológico em nível de indústria, com raras exceções. Baseando-se em evidências da indústria de bioetanol do Brasil, esta pesquisa explora um processo de catch-up tecnológico que tem recebido pouca atenção na literatura. Esta pesquisa adotou um desenho qualitativo com base em uma estratégia de estudo de caso em nível de indústria, com extensivo trabalho de campo e coleta de evidências empíricas de primeira mão com cobertura de longo prazo em 20 organizações. Esta pesquisa encontrou que: (1) a evolução da trajetória tecnológica da indústria de bioetanol no Brasil caracterizou-se pela abertura de uma direção distinta daquela mapeada por líderes tecnológicos existentes. Esse processo de desvio qualitativo da trajetória tecnológica dominante iniciou durante os primeiros estágios de desenvolvimento tecnológico. Assim, a indústria percorreu uma trajetória de entrada precoce em path-creating; (2) a evolução dessa trajetória tecnológica não se deu de maneira homogenia. Foram encontrados três padrões relativamente distintos de acumulação de capacidades tecnológicas para funções (ou áreas) tecnológicas específicas: feedstock, processos agrícolas e processos industriais. Nas funções de feedstock e processos industriais, houve acumulação de capacidades tecnológicas de liderança mundial, enquanto na função processos agrícolas a acumulação de capacidades tecnológicas não evoluiu além do nível intermediário; (3) essas capacidades foram acumuladas de forma dispersa entre os atores da indústria (empresas produtoras, institutos de pesquisa, universidades, fornecedores, empresas de biotecnologia etc.) e possibilitaram a abertura de oportunidades de exploração de novos negócios, ainda que modestamente aproveitadas; e (4) a sutil heterogeneidade encontrada nos padrões de acumulação de capacidades tecnológicas foi influenciada pela combinação de mecanismos de aprendizagem tecnológica utilizados pela indústria ao longo do tempo. Por fim, constatou-se também que essa trajetória tecnológica contribuiu para gerar implicações significativas e foi também influenciada por fatores outros. Não obstante, esses resultados merecem esforço de investigação mais sistemático, uma vez que foram examinados aqui de forma superficial. Concluiu-se, portanto, que posições tecnológicas relevantes, especialmente por indústrias de economias emergentes, podem ser alcançadas por meio de trajetórias tecnológicas que não se baseiam, necessariamente, em tecnologias dominantes, já exploradas por líderes mundiais, de economias avançadas. Assim, os processos alternativos de catch-up podem ser altamente relevantes para a obtenção de progresso industrial. Ademais, a pesquisa concluiu que as indústrias intensivas em recursos naturais oferecem oportunidades para inovações significativas, e podem ser protagonistas nesse processo de catch-up alternativo, particularmente no contexto de países abundantes em recursos naturais. Assim sendo, esta pesquisa contribui para gerar novas evidências e explicações que nos ajudem a ampliar a noção de alternativas para o desenvolvimento industrial e econômico no contexto de economias emergentes. No debate sobre desenvolvimento industrial e econômico, as trajetórias tecnológicas alternativas, bem como as indústrias intensivas em recursos naturais, deveriam receber uma atenção especial por parte de decisores de políticas públicas e de ações empresariais.
