Nova indústria i nova política industrial

La indústria ha tingut, i té encara, un paper clau en la vertebració de l"economia catalana i en la generació d"efectes multiplicadors que faciliten el desenvolupament de la resta d"activitats i el benestar de la societat. Actualment, i més enllà de la crisi econòmica i financera global, s"està generant un nou model industrial d"àmbit internacional caracteritzat per importants canvis en la naturalesa i la dinàmica dels mercats i en les estratègies de les empreses, per la internacionalització dels processos de producció i la seva repercussió sobre l"organització de les empreses i per la creixent importància dels processos d"innovació.

A evolução da indústria petroquímica brasileira

The Brazilian Petrochemical Industry is about to turn fifty years old, and endures profound changes. In less than four years, it has moved from a system of centralized decisions and a national lever of planning, to another which is spread, without massive actions and with less integration with the raw material supplying company. On this issue it is presented, briefly, a small history of the development of this industrial type, including issues on how the growth of this activity, so important to the development of Brazil, shall be lead.

Eletrólise de resíduos poluidores: I - Efluente de uma indústria liofilizadora de condimentos

Wastewater from a seasoning freeze-drying industry was electrolysed to increase its biodegradability. Stainless-steel electrodes were used at 9.09 A/m², for up to 80 min. Conductivity, pH, biochemical (BOD) and chemical (COD) oxygen demands, Daphnia similis acute toxicity bioassays, and bacteria counting through the plate count agar method were determined after different times of electrolysis. The results (e.g. higher BOD and lower COD) showed that the biodegradability of the wastewater was significantly increased; furthermore, Fe2+ ions liberated by the electrodes cause microorganisms to die and, when oxidised to Fe3+, contribute for the flocculation and sedimentation of solid residues.

A nova lei de patentes, a indústria química e a universidade

This paper aims to present some features of the Industrial Property Law now in force in Brazil, as far as they could be regarded to the activities of research and development in the field of Chemistry and related areas, not only in the chemical industry but also in the university. By means of analysis of the main articles and paragraphs, which could deal with the mentioned activities, the author points out the scope and limitations of that law and explains the meaning of common technical terms usually found in patent concerns. Ultimately, a brief discussion on the actual and the potential role of the Brazilian university in the sphere of the Industrial Property is made.

Utilização do resíduo líquido de indústria de processamento de suco de laranja como meio de cultura de Penicillium citrinum: depuração biológica do resíduo e produção de enzima

Penicillium citrinum grown in orange juice processing wastes medium under continuous agitation was studied in order to establish optimal conditions (incubation period, incubation temperature, initial pH and nitrogen addition) for biomass and ribonuclease production, as well as, biological depuration of the wastes. Nitrogen addition to wastes medium increased the biomass and ribonuclease production and provides COD reduction. The soy meal shows to be the best nitrogen source. The conditions for a more favorable enzyme and biomass production and COD reduction were initial pH 6.0 and temperature of 27°C. The maximum value obtained for these parameters on optimal conditions of cultivation was 11 U/mL of enzyme, 4 mg/mL of biomass (dry matter) and 55% of COD reduction, in 96 hours of incubation.

A técnica da reflectância difusa aplicada ao estudo da fluorescência de 2,3-naftalimidas n-substituídas com grupos alquila incluídas em b-ciclodextrina e adsorvidas em celulose microcristalina

The solution fluorescence of N-alkyl-2,3-naphthalimides (1-4) in polar protic and aprotic solvents was compared to the emission from solid samples resulting from the imide complexation with b-cyclodextrin or adsorption on the surface of microcrystalline cellulose. Solid samples of the inclusion complex 2,3-naphthalimides/b-cyclodextrin show maximum for fluorescence emission significantly different to the observed in methanolic solution. Beside this, a clear effect on the alkyl chain length could be observed for these samples which is probably due to differences in probe location inside the cyclodextrin cavity. The constancy for fluorescence quantum yield and fluorescence lifetime for the imides 1 - 4 adsorbed on microcrystalline cellulose suggests that, independently of the polarity of the solvent used for sample preparation, the probe is preferentially located on the cellulose surface. An increase of fluorescence quantum yield and fluorescence lifetime for solid samples, when compared to the values obtained in solution for the different solvents employed in this study (acetonitrile, methanol and water), is fully in accordance with a decrease of the probe mobility due to inclusion in b-cyclodextrin or to adsorption on cellulose.

A indústria petroquímica no próximo século: como substituir o petróleo como matéria-prima?

The world reserves of petroleum will finish in about 100 years. For a tropical country like Brazil, biomass will be the natural substitute for petroleum. For the best utilization of biomass, it first needs to be separated into its principal components: cellulose, hemicelluloses, lignins, vegetable and essential oils, non-structural carbohydrates, bark and foliage. All feedstocks for the chemical industry can be obtained from these biomass components, as shown in the first part of this paper. In the second part we discuss how the major products from petrochemicals can be obtained from the different biomass components. We show that Brazil can use different strategies, compared to other countries, to obtain petrochemical products, which could result in innovations. However, it is necessary that the government starts to invest immediately in order to keep the petrochemical industries competitive with foreign industries, so that they continue to be one of Brazil's major employers.

Exposição ocupacional a compostos orgânicos voláteis na indústria naval

The scope of this study involved the evaluation of the concentration of some volatile organic compounds in the internal environmental air of a naval shipyard in the State of Rio de Janeiro, during painting activities in enclosed, semi-enclosed and open areas. Xylene was the volatile compound found in greatest abundance (25.20 to 191.66 ppm) in the locations researched. Benzene in the air, which is a carcinogenic substance, attained levels of 3.34 ppm in semi-enclosed environments and the highest levels of toluene, xylene and n-butanol were found in the enclosed space of the ship. Results obtained highlight the need to establish air quality control programs in these internal areas, in order to safeguard the health of the workers.

Redução de poluentes de efluentes das indústrias de papel e celulose pela floculação/coagulação e degradação fotoquímica

The abatement of recalcitrant lignin macromolecules from effluents of pulp and paper industry was investigated by combined process. Flocculation and coagulation with aluminum sulfate and natural polyelectrolytes extracted from cactus Cereus peruvianus were used in the first step. After separation of solid residues by filtration, the photochemical methods using TiO2 as catalyst were employed for photocatalytic degradation of lignin compounds from solution. The abatement of lignin compounds after flocculation and coagulation was 46%, and after the overall process, the pollutants reduction observed were 66%. The remaining organic compounds may be removed by any biological treatment.

Caracterização e classificação do resíduo sólido "pó do balão", gerado na indústria siderúrgica não integrada a carvão vegetal: estudo de um caso na região de Sete Lagoas/MG

This research was developed by considering that the solid waste produced in the process of pig iron production represents the loss of raw materials and the increase in environmental problem. The charcoal based mini blast-furnace off gases dust named CHARCOK was collected from SIDERPA ¾ Siderúrgica Paulino Ltda, located in Sete Lagoas, Minas Gerais. The Charcok was characterized and classified according to ABNT (Associação Brasileira de Normas Técnicas) standard. The results showed that the Charcok should be classified as Class I Wastes ¾ "Hazard Wastes" because of its high concentration of phenols (54.5mg C6H5OH/kg). The Charcok had high concentration of iron and charcoal which can be used as energy source.

La força de la indústria

He defensat reiteradament que per poder transformar el país i fer-lo competitiu, Catalunya ha d'optar per l'economia del coneixement. Això no és només produir amb menys cost, que ho és, és produir coses amb noves característiques, amb valor afegit, i arribar a més gent a preus assequibles. La manera de fer això és optar per la recerca, el desenvolupament, la innovació i la transferència del coneixement entre els sectors públic i privat

Coneixement i indústria

En síntesi, l'economia del coneixement, per la qual hem d'apostar, no és eliminar la indústria, és una cosa ben diferent. Apostar per la recerca i la innovació sí, però també una indústria forta que les integri. El govern explica en el seu pla d'acció que s'han identificat i definit set àmbits en els quals centrarà les seves prioritats en política industrial i orientarà les seves accions
