Cleaner Production practices motivators and performance in the brazilian industrial companies
Journal of Cleaner Production, 2019Co-Authors: Jose Augusto De Oliveira, Diogo Aparecido Lopes Silva, Gilberto Miller Devos Ganga, Moacir Godinho Filho, Andre Alves Ferreira, Kleber Francisco Esposto, Aldo Roberto OmettoAbstract:Abstract This research develops a relational model between institutional pressures to adopt Cleaner Production and the environmental, economic and operational performance impacts of such practices. Thus, by using a survey with a sample of two hundred and eight (208) Brazilian industrial companies, it was possible to evaluate the principal motivators driving Cleaner Production in these companies, define measures for the levels of adoption of such practices and analyse their contributions to environmental, economic and operational performance. It was concluded that all institutional pressures exert a positive influence on the levels of adoption of such Cleaner Production practices by the companies, with the pressure exerted by the productive chain, of which the companies form a part, particularly standing out, as well as the pressure from internal and external stakeholders. Moreover, it was concluded that the companies’ environmental, economic and operational performance is positively impacted by Cleaner Production practices supported by pressure exerted on the organizations. This study fills a gap in theory by advancing the frontier of knowledge in this field and serving as a reference for environmental public policies that support business guidelines regarding the need for investment in clean technology.

life cycle assessment in automotive sector a case study for engine valves towards Cleaner Production
Journal of Cleaner Production, 2018Co-Authors: Diogo Aparecido Lopes Silva, Jose Augusto De Oliveira, Remo Augusto Padovezi Filleti, Joao Fernando Gomes De Oliveira, Eraldo Jannone Da Silva, Aldo Roberto OmettoAbstract:Abstract Life Cycle Assessment (LCA) is a well-established tool to analyze environmental aspects and impacts of products and processes. However, there are few studies available regarding LCA of automotive components such as the small parts used by vehicle engines, e.g., intake and exhaust valves. This paper showed a cradle-to-grave LCA of exhaust valves produced in Brazil for automotive use. Based on environmental hotspots of the case study, Cleaner Production scenarios were developed to reduce environmental burdens and to improve manufacturing eco-efficiency. Thirteen midpoint impact categories were evaluated and more than 90% of all the impacts were due to fuel consumption into the internal combustion engine during the valves use phase. Regarding the valves manufacturing phase, the machining processes applied on the valve stem represented 63% of all the impacts, and they were strongly influenced by the consumption of electric energy, raw materials used in the valve stem and cutting fluid. For this reason, Cleaner Production scenarios were evaluated and tested in a centerless grinding process of the valve stem. The best Cleaner Production scenario showed a potential impact reduction up to 72% in the stand-by grinding mode followed by up to 44% less impacts in the dressing mode. Simple changes on grinding parameters produced a huge potential of minimizing environmental burdens in a life cycle perspective, especially in terms of impacts for resources (fossil and minerals) depletion (RD). A comparison between the environmental profiles before and after adopting the proposed Cleaner Production measures showed a significant reduction of 27% on the RD impacts. Therefore, improvements of the exhaust valve's manufacturing parameters can generate a better environmental life cycle performance towards Cleaner Production.

Cleaner energy for Cleaner Production modelling simulation optimisation and waste management
Journal of Cleaner Production, 2016Co-Authors: Jun Yow Yong, Jiři Jaromir Klemes, Petar Sabev Varbanov, Donald HuisinghAbstract:Abstract Energy supply and its efficient use in Production are key to ensuring the healthy functioning of the world economies. Based on that, to ensure sustainability, the supply and use of energy have to apply the principle of minimising negative environmental impacts and even improving the environment through net-regenerative development. In this context, ensuring Cleaner energy is the cornerstone for Cleaner Production, especially for reducing the emissions of greenhouse gases and other pollutants, which are directly related to the types and loads of the energy sources used. This introductory article presents a review of the main lessons recently learned in the area of more efficient energy use, Cleaner fuels and biofuels, Cleaner Production, CO 2 capture, optimisation and waste management. This article provides the readers with ideas and technologies that can be incorporated into real world solutions and can serve as the foundations for future research. With firm realisation of the importance of these issues, the 17th conference “Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction – PRES” was held in Prague, Czech Republic, to provide a platform for discussing ideas and devising solutions for Cleaner energy supplies that are used more effectively and efficiently. This was followed by comprehensive research that resulted in several high quality scientific contributions published in the Journal of Cleaner Production. The wide topical coverage and the high quality provided excellent directions for future collaborative research of the PRES family – including process level emission minimisation, self-sufficient regions, and industrial symbiosis for optimizing usage of waste heat and waste material flows.

recent Cleaner Production advances in process monitoring and optimisation
Journal of Cleaner Production, 2012Co-Authors: Jiři Jaromir Klemes, Petar Sabev Varbanov, Donald HuisinghAbstract:There is a growing understanding that environmental challenges, which mankind is facing cannot be solved by technological or societal sciences alone. An integrated, multi-disciplinary approach is needed, which combines the strengths of new advances in Cleaner Production technologies and political implementation of the policies and programs that are designed to help to ensure sustainable societal development based upon healthy eco-systems. With this aim in mind the organisers of the 14th International Conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction – PRES’11 – and the Editor & Publishers of the Journal of Cleaner Production joined efforts in developing this Special Issue. The main topics include environmental impact assessments, footprint assessment tools, new developments in biofuels and hydrogen Production and sustainable consumption. A major section is also devoted to the increasingly important area of CO2 minimisation. The final part addresses recent advances in electrical vehicles. Key conclusions and future trends include: Cleaner Production is a more and more important part of the planning, design, operation and management in all industrial sectors. To assess and evaluate progress towards more sustainable systems, it is essential that proper monitoring of the environmental and social impacts is done on a regular basis and that the results are used to help focusing societal attention on ways to make further improvements towards sustainable societal lifestyles. Key CO2-related aspects are avoidance, reuse, mitigation and minimisation. The preferred option of Cleaner Production is prevention or minimisation by better product design, process optimisation, monitoring, training and management combined with improved governmental policies that are uniformly enforced for all industrial and business facilities. An inter-linked research field, which is receiving increasing attention is energy storage related to electrical cars. They have the potential to merge several interesting options related to smart grids by using networks of car batteries for low, extra investment, electricity storage. It is anticipated that they, as well as various other opportunities, for Cleaner transport will receive more attention in the coming decade.

the roles of Cleaner Production in the sustainable development of modern societies an introduction to this special issue
Journal of Cleaner Production, 2010Co-Authors: S H Bonilla, C M V B Almeida, Biagio F Giannetti, Donald HuisinghAbstract:This issue of the Journal of Cleaner Production is based upon papers presented at the 1st International Workshop Advances in Cleaner Production (CP) held in Sao Paulo, Brazil, in 2007. The conference had the short-term purpose of deepening the Brazilian discussion on ''The Roles of Cleaner Production in the Sustainable Development of Modern Societies'', and it had the long-term objective of providing an on-going interdisciplinary forum for knowledge development and exchange on Cleaner Production (CP) and Sustainable Development. This issue is devoted to papers covering a broad range of perspectives of CP practices and strategies. A special focus is placed upon methodological tools designed to support effective decision-making pertaining to quantitative benefits from CP. The ten papers provide insights from research designed to holistically integrate CP to help society make effective progress to sustainability. Papers cover the importance of informal knowledge, as complementary to formal knowledge, in performing effective 'Environmental Impact Assessments.' One paper explores the roles of radical and incremental innovation in the context of alternative automotive technologies. Benefits of Ecodesign are explored in two papers; one concerning its integration with remanufacturing to extend the life of used products and one focusing the adoption of 'Emergy Envi- ronmental Accounting,' as a complementary decision-making tool. The development of the Brazilian LCI database for 'hydroelectric power generation' and its contribution to support regionally relevant LCA studies is highlighted in one paper. The complete Production chains of biodiesel and bioethanol are evaluated by using global methodologies, which help in the development of more objective and effective solutions. A ''compensatory area'', calculated in terms of emergy, is proposed in order to work in a sustainable way for bamboo Production. Finally, a paper about a novel approach for recycling used PET is also included. 2009 Published by Elsevier Ltd.
