    • PURPOSE: A composition used for marine algae pretreatment for a process of preparing glucose from marine algae is provided to enable relative saccharification and to prepare a large amount of saccharides of glucose from the marine algae. CONSTITUTION: A solution composition for pretreatment for a process of preparing glucose from marine algae contains 0.1-10 wt% of hydrolysate, 0.1-10 wt% of hydrogen peroxide, 0.1-10 wt% of silicate, and 0.001-1.0 wt% of sulphate. The weight ratio of the hydrolysate and hydrogen peroxide is 1:5-5:1. The hydrolysate includes sodium hydroxide, potassium hydroxide, calcium hydroxide, or ammonium hydroxide. The silicate is sodium silicate, aluminum siliate, boron silicate. A method for preparing glucose from marine algae comprises: a step of putting hydrolysate, hydrogen peroxide, silicate, and sulphate into water to prepare a solution for pretreatment; a step of pre-treating the marine algae with the solution; and a step of adding saccharifying enzyme to marine algae.

    • A solvent recovering method and an apparatus for reducing the volume of expanded plastic waste are provided to reduce the solvent recovering time and to increase the recovery rate of a solvent by excluding a natural drying process for removing moisture and a process for thermal melting, friction heat, or hot blast treatment. A solvent recovering method for reducing the volume of expanded plastic waste comprises the steps of: reducing the volume by pouring a solvent into the expanded plastic waste; heating the volume reduced reactant; collecting the solvent evaporated by heating; and recovering the volume reduced plastic after discharging the solvent. The reactant is heated in an extruder type evaporator(310). The quantity of the inflow reactant and the heating time of the reactant are controlled. The extruder type evaporator has a twin screw. In particular, the heating time of the reactant is controlled by regulating the rotational speed of the twin screw.
