An exploratory diagnosis and proposed index of technological change and sustainable industrial development in selected OECD member countries.

Industrial development has resulted in economic progress and the well-being of the society. At the same time, the impact of the industrial complex has disrupted the environment and resulted in climate change related impacts. The purpose of this study was to carry out an exploratory diagnosis and propose a technological change and sustainable industrial development index at the international level. Therefore, a network study was conducted to identify the main nodes and thematic clusters associated with cleaner production. A patent analysis was applied to technologies related three selected/relevant areas of cleaner production, i.e. carbon footprint, wastewater treatment, and renewable energy. Additionally, based on factor analysis, an index including different indicators related to scientific, technological, economic, environmental, and social issues was developed and proposed in this study.

Biorefinery and sustainability for the production of biofuels and value-added products: A trends analysis based on network and patent analysis.

Biorefineries are modern mechanisms used for producing value-added products and biofuels from different biomass sources. However, a crucial challenge is to achieve a sustainable model for their adequate implementation. Challenges related to technical efficiency and economic feasibility are two of the most relevant problems. Therefore, the present study sought to determine the current trends in basic research and technological development around biorefining and sustainability. We carried out a co-occurrence analysis and a patent analysis using data obtained from the Scopus and Lens databases to provide a general overview of the current state of this area of knowledge. The co-occurrence analysis intends to provide an overview of biorefining and sustainability based on terms associated with these two concepts as a starting point to determine the progress and existing challenges of the field. The results of the patent analysis consisted in identifying the main technological sectors, applicants, and territories where inventions associated with biorefining are registered. The analysis of the information showed that bioeconomy, techno-economic aspects, circular economy, technical issues associated with biomass production, and biofuels represent the focal point of basic research in a wide range of disciplines. Technology development is focused on fermentation, enzymes, and microorganisms, among other areas, which shows the validity of these traditional techniques in addressing the problems faced by the bioeconomy. This scenario shows that developed economies are the driving force behind this area of knowledge and that the PCT system is fundamental for the protection and commercialization of these inventions in places different from where they originated. Furthermore, the challenge lies in learning to work in alternative and complementary technological sectors, beyond microbiology and enzyme applications, in pursuit of the sector's technical and economic feasibility.

The impact of market factors on the development of eco-friendly energy technologies: the case of bioethanol.

Global warming is emerging as the most serious concern for the planet, with greenhouse gas emissions (GHG) contributing considerably to the problem. Consequently, warranting energy sustainability has turned into an urgent issue for scholars and policy-makers alike. Bioethanol has emerged as a viable eco-friendly replacement for avoiding GHG generating fossil fuels. However, bioethanol has faced several hurdles that have discouraged its development during these years. Apart from unpractical technological applications and failed ventures, bioethanol has been experiencing heavy competition from hydrocarbon fuels and adverse economic cycles. Currently, bioethanol is facing an uncertain scenario due to the combination of climbing crop prices and slow innovative production processes, including the cost-effective utilization of agriculture waste. Here, the impact of market conditions upon the competitive development of bioethanol is analyzed. It is argued that fluctuating fossil fuel prices over the last ten years has discouraged bioethanol's technological viability. As a result, the consolidation of industrial biotechnology, especially for biorefineries, has slowed down. Policy implications of recurrent fluctuations in the bioethanol market are also discussed.

Promotion of technological development and determination of biotechnology trends in five selected Latin American countries: an analysis based on PCT patent applications

Background: Science and technology are two desirable elements for the economic and social development of a country. Biotechnology has a particularly important potential for economic development. Nevertheless, patent production in Latin America remains underdeveloped, which creates the need to analyze its trend and the efforts made to promote patent production. Therefore, the purpose of this study was, on the one hand, to determine trends in biotechnology-related PCT (Patent Cooperation Treaty) applications in Chile, Mexico, Argentina, Brazil, and Cuba from 1999 to 2015, and, on the other hand, to determine whether there is a relationship between the gross domestic expenditure on research and experimental development as a percentage of gross domestic product (GERD/GDP) and PCT applications for biotechnological inventions from 2007 to 2015 (in this case, the period under study was limited from 2007 to 2015, due to data availability for GERD/GDP in the five selected countries). Results: The first part of this study shows that the growth in biotechnology PCT applications has been moderate and gradual and the trend was fitted to a linear model. The second set of results shows that GERD/GDP is associated with biotechnology-related PCT applications issued during the study period with a significance level of α = 0.01. Conclusions: Even though results indicate a gradual and modest progress, it is necessary that these five representative Latin American nations continue acting toward the protection of intellectual property in the area of biotechnology, especially by configuring strategies for further progress based on investments on research and development.

Transgenic crops: trends and dynamics in the world and in Latin America.

Transgenic crops have been the recipient of strong support as well as vigorously opposed opinions since their appearance. In any case, their growth throughout the world has been remarkable, and the production and commercialization of transgenics in Latin America has been especially significant. The purpose of the present study was to analyze transgenic crop production trends around the world and the relationship between the area allocated to the cultivation of transgenic crops and the profits generated by this activity. Data concerning Latin American countries and their participation in transgenic crop production are addressed specifically. The present study used covariance analysis, Pearson's correlation coefficient, time series analysis, Dicker-Fuller test, Durbin-Watson statistic, standardization, and different measures of central tendency. Results for the period between 1996 and 2016 show that, despite the significant increase in the area planted with this type of crops, their production presented a deterministic growth behavior, which is explained using a non-stationary model. Current data are insufficient to establish a causal relationship between cultivated hectares and their derived profits. Finally, the present study showed that production increased considerably from 2004 to 2016 in the cases of Brazil, Argentina, Paraguay, and Uruguay, as well as a positive relationship between the global area planted with transgenics and the corresponding area in these selected countries.
