ABSTRACTA surface-cleaning and preparation method that uses high-energy photons and a laminar flowing inert gas has been demonstrated as a feasible technology for broad-based industrial applications such as semiconductors, electronics, optics, coated optical and magnetic media, automotive, aerospace and art restoration. This technology is flexible in tool embodiment and is environmentally friendly because no water and chemicals are not used.

Industri hijau (sustainable) adalah industri yang penggunaan sumber dayanya dilakukan secara berkelanjutan sehingga mampu menyelaraskan pembangunan industri dengan kelestarian fungsi lingkungan hidup serta dapat memberi manfaat bagi masyarakat. Akibatnya, banyak perusahaan manufaktur telah mulai menerapkan praktek SSCM dan secara proaktif menyediakan produk dan layanan ramah lingkungan. Tingginya angka produksi pada industri manufaktur memunculkan isu negative dari segi lingkungan karena industri manufaktur dianggap tidak ramah lingkungan, penyebab perubahan iklim, kerusakan hutan dan penyebab pemanasan global.   Green industry (sustainable) is an industry whose use of resources is carried out in a sustainable manner so as to be able to align industrial development with the preservation of environmental functions and be able to benefit the community. As a result, many manufacturing companies have begun implementing SSCM practices and proactively providing environmentally friendly products and services. The high number of production in the manufacturing industry raises negative issues in terms of the environment because the manufacturing industry is considered not environmentally friendly, the cause of climate change, forest destruction and the cause of global warming.

This study examines global environmental sustainability in an open economy with international trade by studying the pattern of trade between the developed country and the developing country. Assuming that both economies are productive enough to grow and regulate pollution emissions optimally over time via emission tax, it is found that the developing country is bound to specialize in producing the pollution-intensive goods in a growing economy as long as there exists a sufficiently great technology gap in the production of environmentally friendly goods between the developed country and the developing country. The conclusion holds even if the marginal valuation of environmental improvement increases rapidly in the developing country. The developing country needs to export pollution-intensive goods where it has a comparative advantage in producing to finance imports of environmentally friendly goods that it values more over time. It is suggested that global cooperation for technological development to reduce pollution in the dirty manufacturing industry is needed to prevent ever-worsening environmental degradation in developing countries.
