Policy for the Establishment of Recycling Society
Journal of the Korean Institute of Resources Recycling, volume 10, issue 2, 2001, Pages 3~12
Nowadays, countries all over the world are deeply concerned about pollution in the global environment, so they are seeking various ways to adequately disposal of waste. Still, the environmental situation seems to be getting worse and worse. It is evident that such wastes and pollution have been endangering human life nestled in this globe up to the end of the 20th century. We should not, however, tolerate such human misconduct and mal-management of resources any more in the new millenium. For realizing a society that is sustainable for generations to come, it is important to establish a social system for minimizing wastes, promote re-use and recycling, and develop technology for improving recycling efficiencies, including product designs that facil-itate re-use and recycling and innovative technologies for processing wastes. In this paper, reviewing the current status of Korean waste problems, the governmental policy and specific approach for the establishment for recycling society is considered.
Synthesis and Adsorption Characterization of Amidoximated Hydrolyzed Extruded PAN
Journal of the Korean Institute of Resources Recycling, volume 10, issue 2, 2001, Pages 13~19
Several hydrolyzed extruded PAN's were prepared through reaction of extruded PAN (7.5% methyl acrylate) with NaOH in methanol at various temperatures and times. These were amidoximated with hydroxylamine in MeOH and/or
O to introduce an excellent adsorption capacity of heavy metal ions. Amidoximated hydrolyzed extruded fAN showed superior swellability to non-hydrolyzed extruded PAM. The amidoximated extruded PAN hydrolyzed for 6h at
showed the best dimensional stability. Amidoximated hydrolyzed extruded PAN has more adsorption capacity of
than that of
These PAN derivates also showed an excellent selectivity for adsorption of metal ions.
Sulfuric Acid Leaching of Valuable Metals from Spent Petrochemical Catalyst using Hydrogen Peroxide as a Reducing Agent
Journal of the Korean Institute of Resources Recycling, volume 10, issue 2, 2001, Pages 20~26
Sulfuric acid leaching of Mn, Co and Fe from spent petrochemical catalyst was performed using hydrogen peroxide as a reducing agent. Low extraction of Mn, Co and Fe was obtained by only sulfuric acid. When hydrogen peroxide were added as a reducing agent, the high extraction of these metals could be obtained. Different from ordinary leaching, the extraction per-centages of metal components decreased with elevating leaching temperature in this process. Under the optimum condition, the extraction percentages of Mn, Co and Fe were 93.0% , 87.0% and 100% respectively.
A Study on Reusing of Electroless Ni-Cu-P Waste Solution
Journal of the Korean Institute of Resources Recycling, volume 10, issue 2, 2001, Pages 27~33
Reusing of electroless Ni-Cu-P waste solution was investigated in the plating time, plating rate, solution composion and deposit. Plating time of nickel-catalytic surface took longer than that of zincated-catalytic surface. Initial solution with 50f) waste solution additive at batch type was possible to reusing of waste solution. Plating time of initial solution at continuous type took longer 10 times over than that of batch type. Plating time of 50% waste solution additive at continuous type took longer 3.7 times over than that of batch type. Component change of nickel-copper for electroless deposition was greatly affected by depolited inferiority and larger decreased plating rate.
Mechanical Properties of in Recyclate HIPS with Concentration of Fly Ash
Journal of the Korean Institute of Resources Recycling, volume 10, issue 2, 2001, Pages 34~40
Post-consumer dairy HIPS bottles were gathered and recycled by the following processes; crushing into flakes, chemical treatment for the purpose of elimination aluminium caps, washing, and separation from other plastics, such as PP, PE, plasticized PVC These HIPS flakes were extruded into the chips using a single screw extruder. Recyclate HIPS chips were mixed with fly ash as an additive in the range of 5-50 wt%, which were formed from coal power plant. Recyclate HIPS chips mixed with fly ash were molded to investigate thermal and mechanical properties. Their samples, thermal and mechanical properties were measured via DSC, TGA, UTM, and impact strength analysis. The probable mechanical properties exhibited the range of 5∼30% fly ash contents for their applications.
A Research on the Recycling of Ceramic Wastes as an Aggregate for Concrete
Journal of the Korean Institute of Resources Recycling, volume 10, issue 2, 2001, Pages 41~49
In this study, the properties of cement mortar and concrete using ceramic wastes as fine aggregates and coarse aggregates are considered experimentally. Flow value of mortar using ceramic waste as fine aggregates is increased more or less, and the com- pressive strength of mortar using ceramic wastes as fine aggregates is increased with elapsed age. The slump value of concrete using ceramic wastes fine aggregates and coarse aggregates is somewhat decreased. The compressive strength of concrete using ceramic wastes as fine aggregates and coarse aggregates is lower than that of OPC concrete in early age, but has gradually increased in long ages.
