Green product development and performance of Brazilian firms: measuring the role of human and technical aspects

The goal of this study is to present and test a conceptual framework that describes the technical aspects (TA), human/organizational aspects (HOA) of the adoption of green product development (GPD) practices and the effect of these practices on firms'environmental (EP), operational (OP) and market performance (MP). To this end, after reviewing the literature on these themes, a conceptual framework with 5 hypotheses is proposed. These hypotheses were tested on 62 Brazilian companies through structural equation modeling using SmartPLS 2.0M3. The main results of this study are as follows: (a) in general, the proposed framework obtained adequate goodness of fit statistics (GoF); (b) technological factors are shown to have an influence on the adoption of GPD practices, and those practices are related to company EP, OP and MP, thus confirming 4 hypotheses of the study; and (c) one of the study's hypotheses is not validated, indicating that the relationship of human/organizational aspects to GPD must be further analyzed. This work extends the literature because: (a) the conceptual framework tested in this study establishes several concepts that have been only partially tested in the previous literature; (b) this work presents evidence about Brazil, where the themes addressed herein have not been yet been thoroughly investigated; and (c) the non-validation of the hypothesis regarding the relationship between human/ organizational aspects with respect to the adoption of product-related environmental practices requires attention.

Um novo conceito de desenvolvimento econômico: um estudo comparativo entre Brasil e China

This study examines how close Brazil and China are close to the goals set by the new concept of economic development now adopted by major international institutions. Presents a brief history of economic and social trajectory of both countries, with emphasis on advances that have recently occurred in these countries. The study concludes that, although they adopted different ways, both countries moving towards a sustainable economic development

Sistemas de filtragem aplicados em processos fabris automotivos

The present work resulted from a study about coolant filtration systems in industries with metalworking process in large scale. The filtration and element filter world markets move billions of Reais per year and have a promissory future considering that with the global requirements of sustainable economic development, many companies invest in new filtering technology. Either known as coolant or cutting fluid, it is used to lubricate e cool parts during machining and is necessary due to the high volume demanded in the several machining operations and to the high cost of the product. Therefore, there is the need for recycling the product after its use. The work shows the technology and fundamentals of filtration as well as different filtering elements, filtration systems and scale contamination used in the industry. Also, there is a differentiation between filtration of the surface type (cake) and depth filtration and shows the basic theory of filtration by mathematic models in different operational conditions. Ultimately, project criteria for a coolant filtration system selection is shown followed by technical-operational details of a real vacuum filtration system and a case study aiming the operational cost reduction of the system

Limites e possibilidades para a apicultura na região central do Estado de São Paulo

Beekeeping is recognized as promoter of assumptions and dimensions of sustainable development, supported by the triple bottle line – economic viability, social relevance and environmental prudence. Historically, it is strongly related with the central state of São Paulo. This work has as main objective to identify the profile of beekeeping in the this region, based on four municipalities (Araraquara, Descalvado, Rio Claro and São Carlos) in order to determine the main difficulties faced by beekeepersfor the sustainable development, pointing alternative interventions able to soften the effects of difficulties. It was used two different and complementary methodological strategies. The first one was a search with the databases (SEADE and IBGE) to obtain secondary data and quantitative regarding beekeeping in the region. The second one, it wasthrough field research with the beekeepers. The survey found that beekeeping in the region, presents an essentially familial and hereditary. Was also noticed the damage caused in the production, by limiting access to the region’s bee pastures and use of pesticides. In processing, it was found the extremely precarious conditions. At the institutional level, it was found the relative weakness of the beekeepers cooperatives, and the lack of support from local governments to consolidate activity.

As políticas públicas ambientais e a dinâmica do espaço rural no município de Araras (SP)

Historically the evolution of the occupation of ararense territory was due to the expansion of agricultural activities. Such activities were intensified with the transformations engendered by the Green Revolution, increasing the exploitation, the area occupied by agriculture and the deforestation and consequent environmental degradation. Therefore the current reality of rural areas in Araras/SP has shown that part of agricultural practices made it does not guarantee the effectiveness of environmental legislation and the sustainability of farms. Considering the recently implemented environmental policies, such as Law nº 12.651 / 2012, better known as New Forest Code and Decree nº 8.235 / 2014 establishing a period of one year to rural property registered with the Rural Environmental Registry (CAR), as tools targeting to reduce environmental degradation and contribute to building a sustainable rural development. This work aims to analyze the dynamics of the rural municipality of Araras on the environmental situation in some rural properties and actions to be taken by the owners to the full compliance of its properties before the environmental public policy

Development of sustainable precision farming systems for swine: Estimating realtime individual amino acid requirements in growing-finishing pigs

The objective of this study was to develop and evaluate a mathematical model used to estimate the daily amino acid requirements of individual growing-finishing pigs. The model includes empirical and mechanistic model components. The empirical component estimates daily feed intake (DFI), BW, and daily gain (DG) based on individual pig information collected in real time. Based on DFI, BW, and DG estimates, the mechanistic component uses classic factorial equations to estimate the optimal concentration of amino acids that must be offered to each pig to meet its requirements. The model was evaluated with data from a study that investigated the effect of feeding pigs with a 3-phase or daily multiphase system. The DFI and BW values measured in this study were compared with those estimated by the empirical component of the model. The coherence of the values estimated by the mechanistic component was evaluated by analyzing if it followed a normal pattern of requirements. Lastly, the proposed model was evaluated by comparing its estimates with those generated by the existing growth model (InraPorc). The precision of the proposed model and InraPorc in estimating DFI and BW was evaluated through the mean absolute error. The empirical component results indicated that the DFI and BW trajectories of individual pigs fed ad libitum could be predicted 1 d (DFI) or 7 d (BW) ahead with the average mean absolute error of 12.45 and 1.85%, respectively. The average mean absolute error obtained with the InraPorc for the average individual of the population was 14.72% for DFI and 5.38% for BW. Major differences were observed when estimates from InraPorc were compared with individual observations. The proposed model, however, was effective in tracking the change in DFI and BW for each individual pig. The mechanistic model component estimated the optimal standardized ileal digestible Lys to NE ratio with reasonable between animal (average CV = 7%) and overtime (average CV = 14%) variation. Thus, the amino acid requirements estimated by model are animal- and time-dependent and follow, in real time, the individual DFI and BW growth patterns. The proposed model can follow the average feed intake and feed weight trajectory of each individual pig in real time with good accuracy. Based on these trajectories and using classical factorial equations, the model makes it possible to estimate dynamically the AA requirements of each animal, taking into account the intake and growth changes of the animal. © 2012 American Society of Animal Science.

Emergy diagnosis and reflections towards Brazilian sustainable development

This paper presents an environmental emergy-based diagnosis of Brazil compared with Russia, India, China, South Africa and United States. Reflections on the Brazilian sustainable development are presented and discussed based on the evaluations published since 1979. The variation of the emergy per capita for Brazil from 1979 to 2007 indicates that the country's growth is tied to the exploitation of non renewable natural resources which do not directly reflect in the welfare of the population. The total emergy exported per unit of gross domestic product increased in the period, suggesting that the country exports more emergy than that contained in the money received for the exportation. With the help of the emergy indices, the future development of Brazil is explored and discussed. The comparison among the BRICS (Brazil, Russia, India, China and South Africa) countries and United States indicates that what may be appropriate and usable within one country may not be within another and that to achieve the global sustainability two concomitant actions may occur: (i) the reduction of the total emergy use in developed economies, and (ii) the reduction of indigenous resources exportation in developing economies.
