The recycling cell formation problem means that disposal products are classified into recycling part families using group technology in their end of life phase. Disposal products have the uncertainties of product status by usage influences during product use phase and recycling cells are formed design, process and usage attributes. In order to treat the uncertainties, fuzzy set theory and fuzzy logic-based neural network model are applied to recycling cell formation problem for disposal products. In this paper, a heuristic approach for fuzzy ART neural network is suggested. The modified Fuzzy ART neural network is shown that it has a great efficiency and give an extension for systematically generating alternative solutions in the recycling cell formation problem. We present the results of this approach applied to disposal refrigerators and the comparison of performances between other algorithms. This paper introduced a procedure which integrates economic and environmental factors into the disassembly of disposal products for recycling in recycling cells. A qualitative method of disassembly analysis is developed and its aim is to improve the efficiency of the disassembly and to generated an optimal disassembly which maximize profits and minimize environmental impact. Three criteria established to reduce the search space and facilitate recycling opportunities.

Large scale generation of plastic waste has generated considerable interest it seeking innovative solutions to waste recycling and reuse. Plastic solid waste(PSW) treatment and recycling processes could be allocated to four major categories, re-extrusion(primary), mechanical recycling(secondary), chemical recycling(tertiary) and energy recovery(quaternary). This review considers the various aspects of the PSW recycling such as recycling methods of PSW, special problems about some proposed process, separation techniques, and recycling of mixed PSW.

This review paper provides a detailed analysis of PET (polyethylene terephthalate) bottle recycling in Japan. Japan is a global leader in PET bottle recycling due to its advanced regulatory framework and proactive industry initiatives. Japan's success attributes to the widespread adoption of bottle-to-bottle recycling, driven by the beverage industry's commitment to sustainability. By utilizing post-consumer PET bottle recovery and food-grade mechanical recycling technologies, Japan has achieved significant milestones in PET bottle recycling. This paper examines regulatory frameworks, collection systems, reprocessing facilities, and food safety assessments to highlight Japan's innovative approaches to PET bottle recycling and their impact on global sustainability efforts. Drawing parallels with Korea's early stages of PET recycling, it suggests involving major beverage companies and re-evaluating regulations to promote bottle-to-bottle recycling. The focus is on the implications for Korea to promote circular economy principles in plastic recycling.

Recently, E-glass fiber is the one of most widely used ceramic fiber for aerospace fields. Recycling technology for waste of wind power blades is arising issue for reasons of low manageability and high cost of wastes. Though glass fiber is perfectly dissolved in hydrofluoric acid, low cost for recycling and harmless to human is important for recycling of blades. Chemically melted glass fiber will be used as different purpose like accelerator of hardening for shotcrete. In this study, dissolution process of glass fiber is tested in NaOH solution at low temperatures. In addition, difference in diameter reduction of glass fiber is observed by various alkali concentration and reaction times, treatment temperatures using FE-SEM.

Plastic packaging generates less problems than most consumers think, but how to develop the recycling market for plastic waste materials will be critical for the plastic manufacturers. To do this, government must provide enough facility in order to balance economics for plastic recycling market and to run successful recycling programs. Various cost effective recycling technologies have been introduced and also have significant role to boost use of recycled plastics, but this could be only with well organized recycling policy.

In this study, a new process was developed to develop the waste rubber material recycling system. Firstly, the blending of the reclaimed rubber/virgin rubber as a compounding technology was investigated in this study. Secondly, the removal of odor by using zeolite. Thirdly, the continuous crosslinking process technology was studied the technology can solve the environmentally harmful substances and economic problems. Based on this technology, we have started to develop application technologies such as floor mats and rubber sheets for forklifts, and will further study the environmentally conscious products in various ways. Our research will contribute to the recycling industry.
