Nowadays, pollution is one of the biggest challenges for human society. Many types of research are directed toward finding sustainable solutions with minimum or no environmental impact. The contaminants affect the ecosystem components and the people's health equally. Cardiovascular and cancer are only two examples of diseases for which air and food adulteration are directly influenced. For each situation, the conditions need to be evaluated. Environmental accidents or rehearsal ones can determine the risk sources. Regardless of the case, prevention measures are always recommended. Different organic wastes recovery represents a possible solution ensuring an endurable process. Such an approach has to be also looked at from an economic point of view. Renewable natural raw materials usually have lower costs. Independent of the considered strategies, they all have to be based on two pilings. One acts by the authority’s involvement using legislation and standards, and the other refers to society through awareness and implication. The paper highlights some of the most recent and significant findings regarding eco-friendly and sustainable techniques newly developed that were presented in recently published articles. The topics considered essential for this approach regarded the improvements made to increase the city life, the industrial environment, and the laboratory techniques.

Cities can be considered as “complex systems,” since they are characterized by multiple connected elements and by relations among them that are not always recognizable. The massive presence of digital technologies in urban spaces that transform them into “hybrid” spaces makes cities even more complex. This article shows some of the challenges that arise in this new context (e.g., rethinking the people experience in the urban spaces; developing new “urban competences” using in an effective way the large amount of produced data; focusing on the human aspects rather than the technological ones; thinking of sustainable solutions from the environmental, social, and economic point of view; etc.), and it proposes the application of collaborative design frameworks that can offer specific tools and methodologies to face them.

Production Complex

The objective meaning of the sustainable development process in relation to the neo-industrialization of the economy is to create conditions for the restoration of the ecological identity of the national economy as a multi-industry production complex. We consider the neo-industrial development of the economy as the re-establishment of a competitive manufacturing complex in it, capable of saturating the domestic market avoiding increasing the burden on the environment with the innovative development of raw materials production, creating the material basis of national competitiveness in the environmental plan. From sustainable development point of view, neo-industrialization means conducting a comprehensive structural policy, the object of which should be national reproduction, and the subject is deep transformations of the processes that form the complex of human impact on nature, its institutional and technological structure, increasing the reproductive role of the green economy based on the potential of the internal market. At the same time, the history of greening industry, which dates back to the 1990s, testifies to the positive experience of replacing global production chains of raw materials, in particular, energy carriers, with the benefits of a fundamentally new type – alternative energy sources, biomaterials. Therefore, the development of technologically advanced manufacturing industry based on technologies of the green economy is possible as a result of the formation of production of goods and services that are maximally focused on meeting the environmental needs of society.

Article is devoted to the description and the analysis of the system-dynamic model of technological process of biogas production from multicomponent vegetable raw materials. A research objective – optimization of biogas production process from vegetable raw materials by methods of imitating modeling, finding of the optimal regimes of the simulated production cycle – the best ratio from the economic point of view between an exit of biomethane and rates of giving/replacement of the initial substratum depending on the composition of raw materials.In article models with a discrete and continuous cycle of production are considered, the description of the similar realization executed in the environment of multiapproach modeling of AnyLogic for model of technological process of anaerobic digestion of non-uniform multicomponent vegetable biomass is provided.The known stoichiometric model of production of biomethane is taken as a basis, her modification is made for a case of multicomponent raw materials (percentage division into conditional components – sugar, lignin and cellulose). Possibilities of modern software shells and environments of modeling in tasks of the complex analysis and optimization of the studied process are shown.During the conducted researches a row of non-trivial results on a choice of optimum parameters of an operation mode of the model bioreactor is received. For a case of the discrete process of up-dating of contents as parameters of optimization the frequency and a level of up-dating, and for the continuous flowing system – channel speed were selected.It is shown that the optimal values of the parameters from the point of view of the integrated output of the biomethane lie close to the cloud of critical acidification, which leads to the stoppage of the process. If the economic indicators are chosen as an optimization criterion, then we obtain optimal values of the parameters lying within the region of stable functioning of the model bioreactor.

The products from paper are widely used materials with several benefits. The corrugated paper keeps items protected through long-distance logistic processes and constant shipping and handling. The corrugated boxboards are ideal options for any industry’s shipping, packaging and storage needs. Papers and cardboards are quite low cost and also provide environmental-friendly solutions, using recyclable materials such as used corrugated cartons and old newspapers. Recycling offers a reduction in environmental impact in densely populated regions and a large production of paper and board products. Generally, the use of recycled fiber produces paper with poorer mechanical properties due to the decrease in the interfiber bonding. The recycled pulp must be treated to restore its bonding strength, for which there are six methods possible: mechanical treatment, chemical additives, chemical treatment, fractionation, papermaking process modification and blending with virgin fiber. Although some mills produce 100% recycled paper, the majority augment their used pulp with some virgin fiber. Paper properties can be tailored within some ranges by modifying the properties of fibers, but the influence of fine quality on structure, strength and optical properties of paper can be even greater. The properties of papers are essentially determined by their raw materials. Most of these raw materials are made from 100% recycled fiber, but as the quality of the waste fiber varies, different chemicals must be used to provide the desired or expected properties. From an environmental and economic point of view, the use of primary fibers can be an alternative.

The high freshwater consumption requirements in shrimp biorefinery approaches represents one of the major drawbacks of implementing these technologies within the shrimp processing industry. This also affects the costs associated with the plant operation, and consequently, the overall economic performance of the project. The application of mass integration tools such as water pinch analysis can reduce frewshwater consumption by up to 80%, contributing to shrimp biorefinery sustainability. In this work, the economic evaluation and the techno-economic sensitivity analysis for a mass integrated approach for shrimp biorefinery were performed to determine the economic feasibility of the project when located in the North-Colombia region and to identify the critical techno-economic variables affecting the profitability of the process. The integrated approach designed to process 4113.09 tons of fresh shrimp in Colombia reaches a return on investment (%ROI) at 65.88% and a net present value (NPV) at 10.40 MM USD. The process supports decreases of up to 28% in capacity of production and increases of 12% and 11% in the cost of raw materials and variable operating costs without incurring losses, respectively. These findings suggest that the proposed design of the water recycling network coupled to a shrimp biorefinery approach is attractive from an economic point of view.

Reflecting the interest in sustainable development (SD), researches on the attitude toward SD have been steadily conducted for various groups. To explore the characteristics of awareness and attitude of college students majoring in landscape architecture towards the concept of SD, this study has two research questions; to analysis latent classes according to the learning participation pattern (research question 1), and to explore student characteristics that influence the classification of each classes (research question 2). The latent class analysis (LCA) was used to identify the combination of relationships found in the classes based on similar patterns among the characteristics of people rather than the relationship between observed variables. A total of 495 students majoring in landscape architecture, 222 males and 275 females, are participated in this study. The results of this study are as follows. First, six latent classes were extracted in relation to attitudes toward SD. Second, college students majoring in landscape architecture tend to view the concept of SD from an ‘environmental’ and ‘environmental and economic harmony’ point of view rather than from an ‘environmental, social, and economic’ point of view. Third, grades and educational experiences were found to have a significant effect on the probability of belonging to a specific latent class for SD. Finally, based on these results, we suggest a method for organizing interdisciplinary courses to comprehensively access the ‘environmental, social and economic’ areas of the curriculum.

The Development Strategy

The concept of sustainable development in comparison with other paradigms was the most acceptable, from the point of view of determining the development strategy of society, in the medium and long term. Due to that, such important trends in science and practice as the restructuring and modernization of the economy, energy efficiency, environmental security, "green economy", etc. have been developed. One of the most important areas of research, important both for science and practice, is the measurement sustainability of development using the system of indicators. The quantitative measurement of sustainability makes it possible to shape strategies for the development of countries and regions, taking into account the ecological, social factors that previously could not even compete with economic factors. For Russia, this is important from different perspectives. Among the main reasons there is a significant differentiation of regions in terms of development level and the predominance of "raw materials" in the structure of the economy of many regions. Rational use of natural resources is a necessary condition for the sustainable development of any state or region.

Abstract Efforts were made to demonstrate that in biorefineries it is possible to manufacture all the commodities required for maintaining human civilisation on the current level. Biorefineries are based on processing biomass resulting from photosynthesis. From sugars, oils and proteins, a variety of food, feed, nutrients, pharmaceuticals, polymers, chemicals and fuels can further be produced. Production in biorefineries must be based on a few rules to fulfil sustainable development: all raw materials are derived from biomass, all products are biodegradable and production methods are in accordance with the principles of Green Chemistry and Clean Technology. The paper presents a summary of state-of-the-art concerning biorefineries, production methods and product range of leading companies in the world that are already implemented. Potential risks caused by the development of biorefineries, such as: insecurities of food and feed production, uncontrolled changes in global production profiles, monocultures, eutrophication, etc., were also highlighted in this paper. It was stressed that the sustainable development is not only an alternative point of view but is our condition to survive.

It is estimated that the amount of waste electrical and electronic equipment (WEEE) increases annually due to planned obsolescence, technological changes and changes in people's lifestyles. The aim of the present study is to identify risks and opportunities related to WEEE from an environmental, social and economic point of view, considering the intensified use of technology, the generation and the need to treat this waste. The study consisted of a bibliographic research followed by three case studies with waste disposal companies. Therefore, a table was drawn up outlining the risks and opportunities of WEEE, considering different points of view. From the environmental point of view, there is a risk of increasing the consumption of this equipment to increase the illegal and incorrect disposal, but the extraction of non-renewable raw materials can be reduced by implementing reverse logistics. From the economic perspective, the costs involved in the reverse logistics of WEEE are not clearly known; however, there is an expanding market for WEEE management. From the social point of view, the risk is the increase of informal and insecure work, which can be minimized through investments from public and private powers, thus generating formal jobs.
