In order to construct a resources recycling society, waste reutilization as resources is attracting increasing attention. Vitrification treatment has possibilities of not only utilizing waste as civil construction materials, but also recovering valuable chemical components through high temperature treatment. Proposed process recovers phosphorus from incinerator ash of sewage sludge. This process both produces highly utilizable slag, and recovers yellow phosphorus from sludge incinerator ash by vitrifying it in a reducing atmosphere and volatilizing phosphorus. This report verified effectiveness of the phosphorus recovering vitrification process for incinerator ash of sewage sludge.

Two-step liquid-liquid extraction methods using aqueous and organic phases for separation of red (Y2O3: Eu3+), blue (BaMgAl10O17: Eu2+) and green (CeMgAl10O17: Tb3+) fine fluorescent powders were proposed in this paper. At first, the blue powder was extracted selectively into heptane phase using a chelating agent, 2-thenoyltrifluoroacetone (HTTA, CF3COCH2COC4H3S) under alkaline pH condition. Then, chloroform was used for extracting the green powder into the chloroform phase. The red powder separating from the green powder remained in aqueous phase with a depressant, potassium sodium tartrate tetrahydrate (PST, KNaC4H4O6·4H2O). The powders could be well separated in terms of their grade and recovery. The results suggested directions for future research into the recycling of fluorescent powders from fluorescent lights.

The effect of heat pre-treatment in the crushing of granite was investigated. The reduction of crushing energy was found to greatly depend on the prodcut size of granite as well as on the temperature of heat treatment. The magnetization of mica was also observed to increase by the heat treatment.Mica was recovered by first-stage magnetic separtion up to 98% by weight. In order to find one of the possible uses of mica, its aptitude as a filler for resings was examined. Mica was mixed with polyvinylchloride and the mechanical strength of the mixture was measred. As a result, mica showed almost the same reinforcing effect as talc which was popular filler for resins.
