<p>One of the significant methods, which reduce environmental damage, is by using the sustainable elements into construction activities. Bubbled deck is a slab system in which the ineffective concrete in the centre of the section is replaced by HDPE hollow spheres which are produced from waste plastic materials. It offers sustainable structural system due to decreasing (35%) of the self- weight and, therefore, the use and transport of less construction materials. In this study an investigation was carried out on (33) bubbled deck slabs of different dimensions and different sphere diameters, where part of specimens was with openings. The main objective of the study is to determine the impact parameters on increasing the sustainability effect through the input raw materials, energy consumption, and CO2 emissions for the bubbled deck slabs in comparison to solid slabs. Results of the study showed that the reduction of raw materials for bubbled deck slabs led to reduce the energy consumption and CO2 emission by (12%-40%).</p>

Natural stoppers are a magnificent closure for the production of aging wines and unique wines, whose application is limited by the availability of raw materials and more specifically of cork sheets of different thickness and quality. The growing demand for quality wine bottle closures leads to the search for alternative stopper production. The two-piece stopper is an alternative since it uses non-usable plates in a conventional way for the production of quality caps. The present study has analyzed the impact of the manufacture of these two-piece stoppers using different methodologies and for different dimensions by developing an LCA (Life Cycle Assessment), concluding that the process phases of the plate, its boiling, and its stabilization, are the phases with the greatest impact. Likewise, it is detected that the impacts in all phases are relatively similar (for one kg of net cork produced), although the volumetric difference between these stoppers represents a significant difference in impacts for each unit produced.

The problem of climate change is increasingly global and results in environmental damage due to the use of fossil energy in human activities. An increasing population will make energy consumption increase and can make things worse. Therefore, it is necessary to replace old energy with alternative energy that is more environmentally friendly and makes productivity effective and efficient. Renewable energy is pointed out as an alternative energy source that is environmentally friendly and the process is sustainable because it is always available in nature. Renewable energy is expected to increase the country's national income. This study aims to analyze the impact of renewable energy on economic growth in the Asia Pacific region as a whole. By using data from 2000-2015, panel data analysis in this study shows that Renewable Energy Consumption (REC) has a negative and significant relationship to economic growth, while renewable energy and combustible waste (CRW) has a significant and positive effect on economic growth.

Abstract The impact of information and communications technologies (ICT) on the environment is a complex highly-debated subject. Indeed, ICT can have both positive and negative impacts on the environment. While ICT tools and devices can be used to improve energy efficiency, which results in reduced CO2 emissions and environmental degradation, the manufacturing and use of ICT devices can become a major source of emission. Also, many ICT devices contain non-renewable and non-recyclable components that can cause significant environmental damage. Therefore, one may question that whether ICT improves environmental quality in countries with different income levels? To answer this question, this study investigated the environmental impacts of ICT in three groups of high, middle, and low-income countries from 2005 to 2019 using the Generalized Method of Moments (GMM). The ICT Development Index (IDI) was used as the measure of ICT development. Empirical results showed that the use of ICT led to reduced total CO2 emissions, CO2 emissions from solid fuel consumption, CO2 emissions damage, particulate emissions damage, and energy consumption in the studied countries. Therefore, ICT was found to have a generally negative (favorable) impact on environmental degradation in these countries. Considering this effect of ICT on environmental degradation and pollution, governments are recommended to pursue their energy consumption and emission objectives by promoting the use of ICT in the environmental sector and the implementation of green ICT projects.

This article aims to review the resolution of environmental disputes outside the court based on Law Number 32 of 2009 concerning Environmental Protection and Management (UUPPLH). The problem is focused on efforts to protect and restore environmental damage. The method used in this research is normative or doctrinal legal research. Data is collected through a literature approach and analyzed qualitatively. The rapid development of the industry, requires natural resources in the form of raw materials and energy sources that are very large as well. The consequence of the industrial development process is the increase in waste produced by the industry. This is very possible for friction between the surrounding communities, which in turn can lead to conflict or dispute. This study concludes that resolving environmental disputes outside the court is considered more beneficial because if it takes a case in court it takes a long time. By shortening the process the impact of environmental damage can be more quickly addressed so that the ecosystem can soon recover and social, economic and cultural life can proceed as it should.

The Impact

Plastic materials account for about 20% of waste electrical and electronic equipment (WEEE). The recycling of this plastic fraction is a complex issue, heavily conditioned by the content of harmful additives, such as brominated flame retardants. Thus, the management and reprocessing of WEEE plastics pose environmental and human health concerns, mainly in developing countries, where informal recycling and disposal are practiced. The objective of this study was twofold. Firstly, it aimed to investigate some of the available options described in the literature for the re-use of WEEE plastic scraps in construction materials, a promising recycling route in the developing countries. Moreover, it presents an evaluation of the impact of these available end-of-life scenarios on the environment by means of the life cycle assessment (LCA) approach. In order to consider worker health and human and ecological risks, the LCA analysis focuses on ecotoxicity more than on climate change. The LCA evaluation confirmed that the plastic re-use in the construction sector has a lower toxicity impact on the environment and human health than common landfilling and incineration practices. It also shows that the unregulated handling and dismantling activities, as well as the re-use practices, contribute significantly to the impact of WEEE plastic treatments.

Concrete has been used in the construction industry since long times. It is probably the most widely used construction material in the world, largely due to the abundance of the raw materials for cement manufacture, low relative cost and the versatility and adaptability of concrete in forming various structural shapes. Massive production of concrete and the associated substantial manufacture of cement have however been observed to have a very negative impact. One of the biggest issues of growing concern at the moment faced by concrete industries is the impact of cement production on the environment. The production of cement not only depletes significant amount of natural resources, but also liberates a considerable amount of carbon dioxide (CO2) and other greenhouse gases into the atmosphere as a result of decarbonation of limestone and the combustion of fossil fuels. In addition, cement is among the most energy intensive construction materials, after aluminium and steel [1].

Relevance and purpose. The systemic crisis in the mining industry has weakened the provision of the industry with proven reserves of the main types of minerals, which has made the search for technological solutions in order to restore the lost potential of the mineral resource base. Methodology. Theoretical studies of the movement of the grinding charge in the grinding chambers of planetary mills are based on the postulate of the equivalence of the forms of movement of the charge in mills. Grinding equipment of a new technical level is being improved in the direction of increasing the intensity of the effect of grinding bodies on the crushed material. The aim of the study is to increase the intensity of the impact of grinding bodies on the crushed mineral raw materials while minimizing the energy consumption of processing processes. The goal is achieved by integrating analytical and experimental studies with elements of engineering forecasting and modeling of the results. Results and scope. The results of studying the properties of rocks and their changes as a result of crushing and grinding in mechanical mills are presented. Information about devices for measuring the parameters of shock pulses and the practice of their application is systematized on the example of geological differences of rocks. Bench studies have confirmed the theoretically substantiated phenomenon of shock pulse amplitude suppression. The role of the processes of crushing and grinding in mills in the technological chain of waste-free utilization of the tailings of the concentration of chemically exposed ores is detailed. Сonclusions. The phenomenon of increasing the intensity of the impact of grinding bodies on the crushed mineral raw materials with the same energy consumption of processing processes can be used in the modernization of technologies for the development of mineral deposits.
