Green Choices: The Environmental Impact of Consumption Habits

Abstract Ecological footprint is an important indicator used to measure the impact of human activities on ecosystems. This measure reflects how people consume natural resources, the waste they generate, and the state of biodiversity. In modern times, reducing the ecological footprint is an important issue for protecting ecosystems and ensuring sustainable development. The first aspect of the ecological footprint is the efficient use of natural resources. Proper management of water and energy aims to minimize the waste of these resources. The use of renewable energy sources, such as solar and wind power, helps reduce carbon emissions. This approach not only preserves the health of ecosystems, but also meets people's energy needs in a more sustainable way. The second important issue is waste management. Reducing waste in production processes, promoting recycling and recirculation of used materials contributes to reducing the environmental footprint. Each individual can help this process by making small changes in their daily life; for example, reducing the use of plastic and choosing more environmentally friendly products. Biodiversity conservation is also an important part of the ecological footprint. The health of ecosystems is related not only to the availability of natural resources, but also to the diversity of flora and fauna. Implementation of conservation projects to protect rare and endangered species ensures the sustainability of biological diversity. This also affects the strengthening of the relationship between people and ecosystems. Combating climate change is another important step in reducing our ecological footprint. Applying strategic approaches to reduce the carbon footprint is one of the most important tasks facing modern society. It also includes strategies for adapting to the effects of climate change. The active participation of the society in these issues makes it possible to achieve more effective results at the global level.

PRIORITY STRATEGIES TO CREATE AN ENVIRONMENTALLY FRIENDLY BATIK IN TRUSMI VILLAGE

Trusmi village is very famous for batik production, which is manufactured by industrial and small and medium enterprises (SMEs) at various scales. Batik artisans in Trusmi still practice traditional batik technique, which have been passed down from generation to generation for decades. Materials such as mori cloth, wax, and textile dyes, are readily available and sold in Trusmi village. Environmental and health impacts can arise from the production process of stamped and printed batik fabric, which involves the use of many chemicals and exposure to heat in the working environment. The use of chemical dyes in the fabric dyeing process, where craftsmen manually perform the coloring, does not adhere to safety and health. Furthermore, the remaining dye waste is disposed of into the environment without undergoing proper processing. The research aims to address the issue of batik production process waste in Trusmi village, Cirebon, West Java Province, using the root cause analysis (RCA) method. The article presents a root cause analysis of environmental impacts using RCA and provides advice on minimizing environmental effects at the most optimal cost. Based on the result of the research using the RCA method, the most critical strategy identified for achieving environmentally friendly batik production, as determined by the Analytical Hierarchy Process (AHP) and Analytical Network Process (ANP) analysis is to increase the awareness of batik producers.

The Emergence of Different Sustainable Development Approaches According to Environmental Ethics Theories

In recent years, population growth, changes in consumption patterns, urbanization, industrialization, and structural changes in agricultural production have brought about various environmental problems worldwide. At the core of these issues lies the significant impact of viewing nature as a resource repository and a dumping ground for waste in production processes aimed at satisfying increasing consumption. Humanity in the twentieth century came to terms with the fact that these problems also threatened its own existence. Global risks that began with pollution from waste sources and thinning of the ozone layer in the twentieth century have made it imperative for governments to seek solutions beyond their borders in the twenty-first century, particularly with climate change and global warming. The sustainable development approach, under the leadership of the United Nations, has come to the forefront in meetings addressing these challenges. Sustainable development, in essence, envisions restructuring today's activities in a way that they can also be carried out by future generations. However, the fundamental cause of environmental problems is the uncertainty of human domination in human-environment relationships. Measures taken without ethical scrutiny in this context are only aimed at addressing current problems. This study interprets the sustainable development approaches that have emerged in the quest for global solutions to environmental problems through various environmental ethics theories and discusses their theoretical foundations. Within the scope of this study, sustainability approaches are interpreted according to different environmental ethics theories, and different attitudes toward certain environmental problems are attempted to be revealed.

The possibilities of improving the human-machine co-operation in semi-automatic production process

Nowadays, modern production processes are undergoing intensive technological development, according to Industry 4.0 and Industry 5.0 assumptions. Despite the separate differentiation and numbering of these terms, the assumptions of the two approaches do not contradict each other. Industry 5.0 is a type of an extension of the drive for the highest possible degree of integration of automated systems (along with the pillars assumed in Industry 4.0) by finding a place where humans prove to be irreplaceable and their needs are identified as the most essential, central aspect. This leads to the implementation of semi-automated processes in which the cooperation between human and machine is the key. The paper presents an analysis and the results of the studies performed in company that produces vehicle control systems in automotive. The research includes quarter-a-year of studies and observation of production process. The studies aimed identifying waste in production process and proposing improvement methods, with particular reference to automated operations. Implementation of proposed improvements was mainly based on re-programming automated systems, but also on adding new process of cleaning brakes, that allowed to reduce the number of scrapped parts. Moreover, the implicated solutions allowed to achieve reduction of production process cycle time, financial savings and risk of the defects.

How to increase sustainable production in the food sector? Mapping industrial and business strategies and providing future research agenda

AbstractFood waste is a tremendous systemic challenge, mainly at all stages of consumption and the supply chain process. In recent years, the global food supply challenge has called for new methods to decrease food waste or recover them to more valuable materials. Indeed, understanding the techniques for reducing and recovering food waste provides insights into exploring the impact of waste food recovery on the environment. This paper aims to review the literature on food waste in production processes. Hence, we employ a bibliometric and thematic analysis to explore a total number of 163 scientific articles published between 2000 and 2021. The present research uses the theoretical model of circular economy to analyse the literature on the topic both thematically and with cluster analysis. The results provide significant implications for academics and practitioners, drawing attention to a closer relationship between people and food waste, increasing the culture of the value of waste in all processes from agricultural production to distribution and consumption. Finally, it reiterates the need to emphasise the pollution caused by food production.

Negative Environmental Impacts of Production Technologies

The current market environment is affected by several fundamental changes. A large number of these affect manufacturing companies the most. They are forced to continuously reduce their costs, improve the quality of service to their customers and adapt to a highly competitive environment. However, environmental requirements for production processes have become increasingly important in recent years. These are underpinned by legislative changes that put enormous pressure on manufacturers. Often, environmental requirements can also determine the economic success of a manufacturer. The areas that have a significant environmental impact include metallurgical technologies. These are currently predominantly based on the use of coke, which is produced from high-quality hard coal. The mining of raw materials also has significant environmental impacts. The article deals with analysing downstream production processes regarding their environmental impact. These are the areas of mining, ore processing and iron and steel production. These areas can be seen as downstream production stages. Iron ore processing and iron and steel production often occur within a single production organisation. Therefore, a possible overall optimisation in handling environmental impacts and treating pollutants can be assumed. The secondary objective of the paper is to analytically assess the potential reuse of the produced waste in production processes. The article is based on the research results carried out in a selected metallurgical enterprise in the Czech Republic.

Principles of technology optimization and equipment selection when involving municipal solid waste in production processes

Connecting lean and green with sustainability towards a conceptual model

Lean manufacturing has already proven to be an effective management philosophy for eliminating waste in production processes, leading to operational gains. However, nowadays, it is not enough just to obtain economic results, with the environmental aspect being a concern that organizations have been incorporating into their production processes due to stakeholder's pressure in order to increase their sustainable performance. As such, a bibliometric and a structured analysis of the literature were carried out focusing on the connection between lean, green and sustainability concepts. The Web of Science platform was used to collect data, encompassing the period from 1900 to 2020. The carried analyses covered the identification of the most relevant papers, including their authors, as well as their temporal and geographical distribution. There was also focus on the draft of a map to observe an underlying intellectual structure through VOSviewer. The novelty of this research is that, through the gathering of relevant data related to the three concepts considered and their analysis, a conceptual model was proposed consisting of lean-green and sustainability (LGS) tools to achieve superior triple bottom line (TBL) performance. This study pinpointed that in most of the cases where LGS tools have been applied (TPM - Total Productive Maintenance - and 6R, e.g.), there was a positive impact mostly on the economic and environmental pillars of the targeted companies. Although there were also a small number of other cases where it was found that an improved efficiency induced an increased consumption of energy and water, namely by lean tools (SMED - Single Minute Exchange of Dies, e.g.), the results demonstrated the capability of lean and green, especially their combination, to enhance sustainability outcomes. Future research should focus on quantifying the effects that LGS tools, in a single way or combined, bring to all TBL pillars, especially the social one, e.g., by developing key performance indicators. The testing of the proposed conceptual model, including its completion, is also encouraged, namely through the evaluation of what is the best combination of LGS tools, considering specific sectors of activity.

The Important Role of the Designer

This was the sound advice given by British designer Vivienne Westwood, when she was asked in 2018 about ethical and environmental issues in the fashion industry. It remains equally valid in 2020 and will continue to be the ethical code by which we should shop in the future. People in the textile and apparel industry are well aware of their responsibility to create a more sustainable supply chain, to reduce waste in production processes, and to recycle materials whenever possible. And much of the responsibility for these activities starts with the design team—groups of unsung heroes who have to juggle budgets, logistics, strategic plans, technology, aesthetics, functionality, and so much more. Designing goods for sustainability can mean many things—including: • designing high quality, durable products; • designing products that can be disassembled easily at their end-of-life, so that the materials and components can be easily recycled; • designing products which are made from organic, biodegradable, reclaimed or recycled materials and components; • designing products which generate a minimal amount of waste and pollution during their manufacture; • designing products which can be manufactured using machinery that can run on renewable energy, and consume a minimal amount of water; and • choosing manufacturing locations and distribution methods to minimize carbon emissions.

Function framework for describing digital technologies in the context of lean production

Intensifying challenges such as volatility, individualization and consequential complexity increasingly bring lean production systems to their performance limits. Using digital technologies serves as possible solution to overcome the limits of lean production and to enhance its capability of reducing waste within production processes. Therefore, a holistic and generic approach is required that allows to characterize digital technologies with respect to their effects on reducing waste in production processes. This paper introduces a function framework that describes digital technologies based on a function-oriented and impact-driven attribution concerning their effects on reducing waste and therefore on superordinate goals of lean production.

Penerapan Produksi Bersih untuk Meningkatkan Efisiensi Proses Pelapisan Logam

Metal coating wastes generally bring about environmental health problems resulting from liquid wastes that contain heavy metals. The waste processing carried out thus far does not solve the problems because it just move wastes to other media. Cleaner production comes to be an alternative in minimizing liquid wastes, for water consumption, and for raw material. The present research was intended to identify wastewater resulting from the production stage, get cleaner production opportunities that can be applied, and give priority to clean production opportunities. The research stages began with a quick scan to identify the sources of wastes in production process and to determine an alternative of cleaner production chance, and then an economic computation was done, including B/C ratio and payback period. The determination of the priority of cleaner production technique given to a company was conducted by using exponential comparison method. The results showed that liquid wastes were originated from the process of fat removing, metal coating and process of cleaning up the remaining oxides. Liquid waste or loss in the form of contaminated fat solvents, the quite great loss of water due to evaporation and leakage. Cleaner production opportunities that can be applied by modifying/adding tools so as to prevent alkali solutionfrom being contaminated, reducing evaporation and reducing leakages by good housekepping. Three opportunities for cleaner production obtained to have B/C Ratio of more than 1 is can be implemented. Based on the exponential comparison method, the main priority of cleaner production is found, that is pipe changes in the residual oxide cleaning process to avoid leakage, technically and operationally the easiest to implement and followed successively with modifiying/adding tools to process of fat removing and metal coating.
