A case study on the designing of tururi fiber's composites and its potential use as a sustainable material for product design.

O objetivo da presente pesquisa foi analisar a criação de compósitos da fibra vegetal amazônica tururi (Manicaria saccifera Gaertn.) com a resina epóxi-vinil-éster como potencial material sustentável para o design de produtos, segundo a óptica de projeto de Manzini e Vezzoli (2002). Para tanto, analisou-se o ciclo de vida do compósito produzido com o método de infusão a vácuo. Buscou-se apreender as várias fases que diferenciam a entrada, permanência e a saída de um compósito como material para o mercado. Notou-se que o material desenvolvido tem potencial para a utilização no design de produtos como um produto sustentável pois apresenta um baixo impacto em sua pré-produção, produção, montagem e descarte.This research aimed to analyze the creation of composites made of the Amazonian fiber Tururi (Manicaria saccifera Gaertn) with epoxy-vinyl-ester resin as a sustainable material for product design, according to Manzini and Vezzoli's project perspective (2002). For this purpose, we analyzed the life cycle of a composite made of tururi fiber and epoxy-vinyl-ester resin, produced using the vacuum infusion method. We aimed to apprehend the various phases of entry, permanence and exit of such composite as an option for the product design market. It was noted that the developed composite has the potential to be used in product design as a sustainable material due to the low environmental impact of its pre-production, production, assembly, and disposal

Mechanical characterization of the green coconut fiber for application in the footwear industry

In the tropical countries, the green coconut water consumption generates a great problem with the fruit \ud final destination. To minimize this problem, it is necessary to find applicability to the residues. In this \ud sense, this study had as its objective to investigate the characteristics of the green coconut fiber, from the \ud fruit disposed in the city of Francisco Morato – Sao Paulo, and to compare them to the characteristics from \ud other natural fibers, to check the viability of application of these fibers in the manufacturing of shoe parts. \ud It was made a biological maceration on the fibers and traction and microscopy tests were run. The results \ud showed that the green coconut fibers have potential related to other natural fibers studied in literature, to \ud be used as reinforcement in the manufacturing of shoe parts and other design product

Outer membrane vesicles (OMV) production of Neisseria meningitidis serogroup B in batch process

AbstractSerogroup B outer membrane vesicles (OMV) with iron regulated proteins (IRP) from Neisseria meningitidis constitute the antigen for the vaccine against the disease caused by this bacterium. Aiming to enhance final OMV concentration, seven batch experiments were carried out under four different conditions: (i) with original Catlin medium; (ii) with original Catlin medium and lactate and amino acids pulse at the 6th cultivation hour; (iii) with Catlin medium with double initial concentrations of lactate and amino acids and (iv) Catlin medium without glycerol and with double initial concentrations of lactate and amino acids. The cultivation experiments were carried out in a 7-L bioreactor under the following conditions: 36°C, 0.5atm, overlay air 1L/min, agitation: 250–850rpm, and O2 control at 10%, 20h. After lactate and amino acids exhaustion, cell growth reached stationary phase and a significant release increase of OMV was observed. According to the Luedeking & Piret model, OMV liberation is non-growth associated. Glycerol was not consumed during cultivation. The maximum OMV concentration value attained was 162mg/L with correspondent productivity of 8.1mg/(Lh) employing Catlin medium with double initial concentrations of lactate and amino acids. The obtained OMV satisfied constitution and protein pattern criteria and were suitable for vaccine production

Buriti palm fiber (Mauritia flexuosa MART.): characterization and studies for its application in design products

Abstract. Buriti (Mauritia flexuosa Mart.) is the most common and abundant palm tree in the Brazilian territory and it is present throughout South America. It is known as the "Tree of Life", because everything in it can be used and many residents of rural communities have this palm tree as their main source of income. In different Brazilian states, the fibers removed from young leaves of the Buriti palm tree are employed in the manufacturing of handicraft, being this fiber popularly known as "flax or silk" of buriti. In order to apply the "flax or silk" of buriti in new products, it is necessary to study their physiochemical characteristics, as well as to monitor the handling of the palm tree, the extraction process of the fiber and its application in handmade products. The buriti fiber analyzed in this study is from the Brazilian Cerrado biome, more specifically from the town of Barreirinhas (Maranhão State). The fibers were tested in order to determine tensile rupture strength, tenacity, elongation, Young's modulus, cross microscopic structure and regain. In order to carry out the tests, the fibers were separated in 5 groups: 1) in natura fibers, 2) fibers boiled by the origin community, 3) fibers boiled in bleach, 4) fibers boiled in softener, and 5) fibers boiled in lemon juice, being the processing of last three groups done in the city of São Paulo. The group used for cross and longitudinal microscopy was in natura fibers. The groups of fibers referred were also maintained in water at 37°C for 21 days to determine its reaction and resistance to weather and were analyzed every 3 days. The results of tenacity, elongation and Young´s modulus for each group were respectively: 1) 28.4±5.6 cN/tex (CV=20%), 8.3±0.6% (CV=7%), 6.1±0.8 N/tex (CV=13%); 2) 31.0±7.7 cN/tex (CV=25%), 8.4±0.8% (CV=9%), 7.2±0.7 N/tex (CV=10%); 3) 27.6±7.2 cN/tex (CV=26%), 7.9±0.6% (CV=7%), 6.0±1.2 N/tex (CV=20%); 4) 22.1±8.8 cN/tex (CV=40%), 8.6±1.9% (CV=22%), 5.0±1.0 N/tex (CV=20%); 5) 29.7±6.5 cN/tex (CV=22%), 8.6±0.6% (CV=7%), 5.8±0.8 N/tex (CV=13%). Through this study it could be possible to expand knowledge regarding the potential of the Brazilian biodiversity, presenting applications for the buriti fiber in the development of new products to be employed in design and industry as well as collaborating in the construction of social benefits by encouraging the recovery and strengthening of local cultural identity, community organization around solidarity economy and consequent generation of income for fibers extractive communities

Reciclagem de resíduos do setor têxtil e confeccionista no Brasil:: panorama e ações relacionadas

O Brasil se configura como um dos maiores produtores mundiais do setor têxtil e vestuário. É um importante produtor da fibra de algodão, de fios, de tecidos planos e de malha, além de estimular o PIB do País gerando milhões de empregos diretos e indiretos no referido setor. Contudo, tal atividade cria diversos problemas ambientais como, por exemplo, a geração de resíduos sólidos oriundos dos processos industriais, confeccionistas e também do pós-consumo. O presente estudo visou apresentar o panorama atual dessa problemática e apontar possibilidades de reciclagem têxtil. Como metodologia, foram analisadas literatura científica, patentes, legislação e outras fontes bibliográficas, bem como foram consultadas informações de diferentes órgãos e instituições relacionadas ao setor têxtil, confeccionista e meio ambiente. Além disso, foram analisadas manualmente amostras de resíduos têxteis cedidas por uma indústria recicladora a fim de constatar algumas problemáticas referentes ao processamento desse material. Assim, apresenta-se um panorama sobre a reciclagem têxtil no Brasil, relacionando as principais problemáticas ligadas a essa atividade, ainda não muito estimulada em nível nacional
