  • The adsorption features of nickel ion in wastewater on manganese dioxide from spent batteries were investigated for its usage as an adsorbent. The aquatic behavior of nickel ion was characterized by MINTEQ program and the considered influential variables on the adsorption of nickel ion were its initial concentration, reaction temperature, the amount of adsorbent, and pH. The adsorption ratio of nickel ion decreased with increasing its initial concentration and thermodynamic estimation has been carried out based on the adsorption characteristics of nickel ion depending on temperature. In addition, the adsorption of nickel ion was shown to be promoted according to the amount of manganese dioxide and a lot of nickel ions were adsorbed as the solution pH was raised.

  • In this paper the world wide patents on the recycling of used batteries were inspected. The trend and direction of on-going and future technologies on this matter were analyzed. The range of search was limited in the open patents and in DB of U.S.A.(USPTO, DLPHION), Japan(PAJ), Europe(EPO), and Korea(KIPRIS). For the search condition the keyword, battery, batteries, electric cell, patent, and recycling, and IPC classification were used. The total of 2,490 cases was found at the first search stage, then, through the 2 steps of filtering processes the total of 871 cases was selected for the final analysis. These 871 cases were classified by countries, companies, and technologies between the year 1971 and the you 2000.

  • This study was carried out for establishing the physical recycling technique for commercializing process on household batteries. The procedure involves shape separator, crushing, magnetic separation, classification and eddy current separation in sequence. The separation capacity was 400-600 unit cell/hr with shape separation system. The impurities such as manganese and zinc in the magnetic product were below 0.1% respectively, the concentration of iron was above 99% in spent carbon zinc battery. Also non-magnetic products are composed of 22-30% En, 16-22% Mn, 1-3% Fe in the case oi spent zinc carbon battery. The amounts of other components such as carbon rod, plastics and separator were about 37-50%. From the eddy current separation of nonferrous products, the plate-type zinc components were separated up to 96% with 2,250-2,750 meter/min of the conveyor speed.

  • This study was conducted to analysis citizen's attitude and style to the foodwaste from loth Sept. to 30th Sept. in 1996. The research was used questionare method and the analysis was used prequency analysis and cross table method by SPSS (scientific statistics). they answered that the most serious environment problem was waste problem and the best way to settle waste problem was to reduce waste production itself. And they answered that to settle environment problems, it was most important for us to change our life style. But It was not agreed between consciousness and action(execution). Because most of the food-related waste was among household waste, it's settlement was the most importment thing than any other. Nevertheless the seperation of waste was essential to effective incineration, the seperation process was not actually conducted and only a few housewife knew the difference of incinerable and non-incinerable waste. The recycling for the disused dry-cells and garbage is not completly. But we think that if the effective government's recycling counterplan for wastes, foodwaste or wasted dry cell, etc., is estabilished, rates of seperation and collection was increasing. Much usuage of onetime vinyl bag for shopping was become the one of the main cause in increasing the package waste, and so it was needed to use the longlife shopping basket.
