With the development of science and technology and industry level, solid wastes are fully utilized. Among which gangue is the solid waste generated in the process of coal mining, its comprehensive utilization rate is more than 60%. Environmental pollution in the process of coal mining is one of the typical environmental problems confronted in China. In this paper, the life cycle inventory (LCI) of gangue was acquired by the method of life cycle assessment and further environmental impact assessment was achieved as well. The results showed that environmental impacts based on allocation of calorific value were greater than that of economic value, and it’s about 3.68 times the impacts assigned by economic value. Therefore allocation of economic value was better.

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.

Goal And Scope

Life Cycle Assessment (LCA) adalah salah satu cara yang dapat digunakan untuk mengevaluasi sistem pengelolaan sampah berdasarkan nilai potensi dampak yang dihasilkan. Bank Sampah Asoka Berseri di Kabupaten Tuban merupakan salah satu contoh unit pengolah sampah yang bertujuan untuk mengurangi potensi dampak dari timbulan sampah secara kualitas maupun kuantitas di wilayah pedesaan. Tujuan studi ini adalah menghitung dan mengevaluasi potensi dampak lingkungan yang dihasilkan dari program bank sampah, kemudian dibandingkan dengan penanganan sampah konvensional yang dilakukan oleh masyarakat. Metode yang digunakan berdasarkan CML Baseline v4.4 dan 14000 standar ISO, meliputi goal and scope, life cycle inventory (LCI), life cycle impact assessment (LCIA) dan interpretasi. Simulasi LCA dilakukan dengan Software OpenLCA untuk menghitung nilai potensi dampak dari setiap kilogram sampah yang dihasilkan. Berdasarkan hasil simulasi, setiap 1 kg sampah yang dikelola oleh bank sampah menghasilkan potensi dampak pemanasan global lebih rendah (6,395 kg CO2 eq.) dibandingkan dengan penimbunan (13,057 kg CO2 eq.) dan pembakaran (10,850 kg CO2 eq.). Pengolahan sampah lebih lanjut menjadi RDF dan kompos di bank sampah berpotensi menghasilkan dampak lingkungan lebih rendah dan menambah pendapatan masyarakat.

Reflective Foil

In the last twenty years, the exploitation of non-renewable resources and the effects of their applications on environment and human health were considered central topics in political and scientific debate on European and worldwide scale. This kind of resources have been used in different sectors, as energy systems, technological research, but also in private/public buildings and production of consumer goods, involving significantly domestic and ordinary life of every human being. Studies about the effect of this exploitation carried out discouraging results, in terms of climate changes and energy sustenance; this determined a progressive approach process to a new concept of development, able to couple the qualitative standard of modern life with the respect of planet and its inhabitants. Starting from this reflection, scientific community moved towards research on alternative resources and developed a new way to conceive planning process and technical innovations, in order to exploit renewable energies and recycled materials, promote energy savings and reduce environmental pollution. In this context the present paper aims at evaluating benefits relating to different solutions of thermal insulation in building envelope. In fact a high grade of insulation ensures better comfort conditions in inner spaces, reducing energy consumptions due to heating and cooling conditioning. The paper presents the results of a detailed Life Cycle Assessment (LCA) of the reflective foil ISOLIVING, conceived and produced by an Italian company. The Life Cycle Assessment methodology allows to consider all stages of the life cycle, from the extraction of raw materials to the product’s disposal, in an optics “from cradle to grave.” In particular, the study takes into account the production phase of the reflective foil ISOLIVING, the installation phase, the transport of all components to the production site and also the end of life scenario of the material. The possibility to collect many detailed information about the production phase adds value to the study. The analysis is carried out according to UNI EN ISO 14040 and UNI EN ISO 14044, which regulate the LCA procedure. The LCA modeling was performed using SimaPro software application. The results of the analysis allow to make an important comparison concerning the environmental performances, between the reflective foil ISOLIVING and other types of insulating materials.

Abstract There is no clear direction in the management of electrical and electronic waste products (e-waste), as there are no regulations on ways to do so. This research attempts to understand the trade-off between economic value and environmental effects of the current disposal of e-waste to find ways to optimize waste management, focusing on cellphones, television CRTs, desktop computers, and air conditioners. A Life Cycle Assessment (LCA) is a tool that can analyze various influences, e.g., environmental, costs, and value added. Under the e-waste management status quo, most household e-wastes are kept in houses because owners do not know where to discard them. In addition, informal sectors, such as domestic farmers or workers, have been involved actively for more than a decade, leading to poor management standards for both health and the environment. The logistics are inefficient because the dismantling communities and recycling industry are far apart. Most e-waste is generated, and most recycling industries are located, in the Central region (the richest areas), while the dismantling communities are located in the Northeastern region (the poorest areas). Further, LCA and LCC of e-waste are sensitive to transportation, and not all e-waste parts can be recycled within the country. High-tech mineral extraction cannot be practiced in the country, and thus, circuit boards and batteries are exported for recycling. To promote a circular economy, e-waste management regulations should be implemented and a full recycling industry should be established in the country.
