This paper is based on the lecture delivered at the First South East European Congress of Chemical Engineering (SEECCHE1) held on September 25-28, 2005 in Beograd, Serbia. Time constraints did not permit me to publish it in the proceedings of the conference, and since the topic considered is very much pertinent to the current developments in our profession, it seems appropriate to present it in this special issue of the same journal that carried the papers from that conference. In addition, the paper represents a small tribute to my brother Aleksandar for his dedicated work in emphasizing the importance of fundamentals in chemical engineering education. In this paper an attempt is made to illustrate to the younger generations of chemical and process engineers the importance of reaction engineering and its relevance to societal needs globally. The slides and comments of the talk given at SEECCRE1 are made available on a web site indicated at the end of the paper.

This study evaluates the total length of tambaqui (Colossoma macropomum ) captured in the middle Solimões river and traded during seven years (1993, 1997 and 2000 to 2005) in the Tefé market, Amazon, Brazil. The Mamirauá Institute of Sustainable Development obtained measurements of the total lengths from 42207 individuals. The length average was 45.23 ± 6.29 cm (minim um of 13 cm and maximum of 105.5 cm ) and the mode was 45 cm . From the total tambaquis, 92.86% were smaller than 55 cm and 7.14% measured 58.24 ± 5.41 cm on average. Medium and standard deviation of the lengths recorded in all years showed sizes below the established by the environmental federal agency. The Kruskal Wallis test showed that there is no significant difference between the abundances and medium sizes of the captures during all months of the year. The historical data of the tambaqui fisheries for the middle Solimões region indicate that individuals of this species have been constantly captured at sizes below the minim um length of reproduction. Nine recommendations for tambaquis fisheries management in the region related to more efficient mechanisms of inspection, auto-ecology studies of the species, environmental protection, reduction of fishery pressure, diffusion and educational cam paigns that aim to correct exploitation of this resource are presented in this manuscript.

As the world’s largest developing country, and as the home to many of the world’s factories, China plays a crucial role in the sustainable development of the world economy regarding environmental protection, energy conservation, and emission reduction issues. Based on the data from 2003–2015, this paper examined the green total factor productivity and the technological progress in the Chinese manufacturing industry. A slack-based measure (SBM) Malmquist productivity index was used to measure the bias of technological change (BTC), input-biased technological change (IBTC), and output-biased technological change (OBTC) by decomposing the technological progress. It also investigated the mechanism of environmental regulation, property right structure, enterprise-scale, energy consumption structure, and other factors on China’s technological progress bias. The empirical results showed the following: (1) there was a bias of technological progress in the Chinese manufacturing industry during the research period; (2) although China’s manufacturing industry’s output tended to become greener, it was still characterized by a preference for overall CO2 output; and (3) the impact of environmental regulations on the Chinese manufacturing industry’s technological progress had a significant threshold effect. The flexible control of environmental regulatory strength will benefit the Chinese manufacturing industry’s technological development. (4) R&D investment, export delivery value, and structure of energy consumption significantly contributed to promoting technological progress. This study provides further insight into the sustainable development of China’s manufacturing sector to promote green-biased technological progress and to achieve the dual goal of environmental protection and healthy economic growth.

The aim of this editorial is to explore, conceptualize, and research the need to internalize both animals and ecosystems in our understanding of social citizenship and social policy. This editorial should be seen as a brief overview of the themes that should be covered in the contributions to the Special Issue, “Internalizing Animals and Ecosystems in Social Citizenship and Social Policy: From Political Community to Political Country”. This Special Issue argues the importance of integrating animals and ecosystems as a way to re-politicize humans’ social relation with both animals and our ecosystem as in sustainable development and social policy. If environmental policy becomes social policy, we would re-construct social citizenship to include consideration for animals and ecosystems as integral part of social policy. This expansion in scope is a progression from seeing humans as part of a political community to becoming more involved in their political country. This aligns with the concept of Country—an all-encompassing term in Australia, involving a people’s territory, land, water, biological resources, the complex obligations and relationships involved.

The need for sustainable development underscores the role and importance of integrating environmental concerns in non-environmental policies because it is evident that environmental regulations only are insufficient to manage all environmental issues. Law enforcement on environmental protection in Vietnam clearly demonstrates this situation. Vietnam’s legal system of environmental protection is incompatible or overlapped with other sectoral laws and in fact many environmental matters have been implemented in accordance with sectoral laws while disregarding environmental considerations due to the lack of specific and explicit environmental provisions or requirements in sectoral laws and regulations. From that situation, the paper emphasizes the need to integrate environmental protection requirements into the sectoral laws of Vietnam and proposes some fundamental criteria and procedures to integrate environmental requirements into sectoral laws.

The Arctic Council is an intergovernmental forum promoting cooperation, coordination and interaction among Arctic states, indigenous communities, and peoples on issues of common importance. The rising geo-political importance of the Arctic and the onset of climate change has resulted in the Council becoming a focus of increasing interest from both inside and beyond the Arctic. This has resulted in new demands placed on the Council, attracting an increasing number of participants, and instigating a period of transformation as Arctic states work to find a way to balance conflicting demands to improve the Council’s effectiveness and take care of national interests. This paper considers whether, during this time of change, the Council is having an impact on the issues it was formed to address, i.e., environmental protection and sustainable development. To provide answers, it looks at how the Council reports on and evaluates progress towards the implementation of recommendations it makes regarding biodiversity, how it identifies where activities have had impacts and uncovers the mechanisms through which they were successful, to provide an insight into how the Arctic Council can be an agent of change.

High Ti-bearing blast furnace (BF) slag is the smelting waste of vanadium titano-magnetite. It has great production but low utilization. The high Ti-bearing BF slag is used in building materials industry, which recycles waste material, saves resources and energy, benefiting environmental protection and achieving sustainable development of resources. Study on the recycling of high Ti-bearing BF slag will be an important subject of our researches in future.
