“…According to environmental impacts, works carried out by Iriarte et al 34 showed that at urban subsystem level, the collection system with the least impact (following a life cycle assessment) is multi-container collection between three options (the mobile pneumatic, the multi-container and the door-to-door). Nevertheless, other works in Historical Centres in Spain showed that when the organic fraction is collected separately, the pneumatic collection could be a suitable alternative because the energy requirements are balanced with the savings from the anaerobic digestion process 35 .…”

According to EU regulations, member states shall take measures to encourage the recycling of biowaste in a way that fulfils a high level of environmental protection. In Spain, the separate collection of biowaste is only implemented in some regions. For this reason, a pilot scheme based on an information campaign and the location of a specific brown container for biowaste in specific zones of the city was carried out in Castelló de la Plana (Spain) over a period of six months. In this period, the collection and composition of the biowaste was monitored in depth with the goal of determining the evolution of the efficiency of the new collection system over time. In the zones, the quality rate in the biowaste container increased as the pilot study progressed, finally reaching 90%. The rate of biowaste separation also increased in the three zones over time, although in different ways, which means that there is greater collaboration on the part of citizens. On the other hand, an analysis of the rate of net biowaste daily collection from zones 2 and 3 has shown that their value increases as the rate of containerization of biowaste decreases. Therefore, to obtain better results it will be necessary to increase the containerization of biowaste, that is, to reduce the distance from the citizen to the container. It can thus be said that there is a positive evolution of the experience, which boosts confidence when it comes to implementing the system throughout the city.

“…While this technology apparently reduces local direct air emissions, it has a large energy demand caused by the need for generating vacuum for waste suction. Laso et al [118] presented an analysis that compares conventional door-to-door and pneumatic waste collection systems using Life Cycle Analysis. The considered system boundary includes accounting for the creation, installation, maintenance, and decommissioning of the waste collection system, as well as for the waste transfer, sorting and waste processing sub-systems.…”

Towards Efficient and Clean Process Integration: Utilisation of Renewable Resources and Energy-Saving Technologies

et al. 2019

View full text Add to dashboard Cite

The strong demand for sustainable energy supplies had escalated the discovery, and intensive research into cleaner energy sources, as well as efficient energy management practices. In the context of the circular economy, the efforts target not only the optimisation of resource utilisation at various stages, but the products’ eco-design is also emphasized to extend their life spans. Based on the concept of comprehensive circular integration, this review discusses the roles of Process Integration approaches, renewable energy sources utilisation and design modifications in addressing the process of energy and exergy efficiency improvement. The primary focus is to enhance the economic and environmental performance through process analysis, modelling and optimisation. The paper is categorised into sections to show the contribution of each aspect clearly, namely: (a) Design and numerical study for innovative energy-efficient technologies; (b) Process Integration—heat and power; (c) Process energy efficiency or emissions analysis; (d) Optimisation of renewable energy resources supply chain. Each section is assessed based on the latest contribution of this journal’s Special Issue from the 21st conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction (PRES 2018). The key results are highlighted and summarised within the broader context of the state of the art development.

“…Apart from distinct environmental, social and economic advantages, according to some authors, production of BF may open a door for the transition of economy from the linear model to the closed cycle model or "circular economy" [188][189][190][191][192]. It is believed that transition to the circular economy is the most efficient method to provide sustainable development.…”

Diffusion of the biofuels (BF) using is justified by opening up the opportunities for obtaining fuel and energy from previously inaccessible sources and by the existence of energy-deficient regions, in particular in Russia. Works of different scientists on the problems of creating and using BF were the methodological basis of this study. Information on the state and prospects of the development of renewable energy sources in Russian regions was collected from regulatory documents and was obtained by employing a questionnaire survey. For the study of the collected materials, the different methods of comparative analysis, and the methods of expert assessments were used. The results of the Status-Quo analysis of BF production in Russia have shown that the creation of BF performed relatively successfully. However, there are many more perspectives, connected with expanding the utilization of the different raw materials. Also, the analysis of organizational and economic mechanisms applied for production of BF and the obtained data on several organizations-producers allowed for proposing six indexes for the assessment of the BF production effectiveness. It is suggested that BF production in Russia will contribute to the sustainable development of a number of the country's regions in the near future.Energies 2019, 12, 3948 2 of 30 impact of permanent anthropogenic factors has required the taking of appropriate measures in this field both at the federal and regional levels. In particular, the accumulation of industrial, agricultural, and household wastes is becoming an essential incentive for the development of innovative activities aiming at the production of biofuel (BF). According to the existing data [3], the resource potential of recyclable organic waste biomass, including solid household wastes and sediments of wastewaters reaches 13,490.26 tons of coal equivalent (TCE) per year in Russia. This study led both at the federal level and in particular regions which have significant differences in terms of economic, geographic, and climatic conditions. According to pessimistic forecasts, the share of green energy in the Russian economy will arrive at 3-5% by 2035, according to positive ones, it will be equal to 8-10%. The proposed share of BF in the production of electric and heat energy with targeted management could be about 2-3% [4].Different geographic, climatic, economic, and other conditions in regions of Russia necessitate solving several scientific problems for optimization of the existing regional programs for the provision of sustainable development and determination of the role of REn and BF production in them.Therefore, the progress in BF production achieved in some leading countries has become a significant factor which causes a positive impact on the sustainable development of their economies. This gives rise to the suggestion that Russia has some conditions for a more extensive application of REn, in particular, for BF production and use. Correspondingly, this article characterizes some general trends of B...
