Abstract: PURPOSE: A regeneration method of corrugated cardboard waste is developed to efficiently improve the strength and the dehydration property of the cardboard by using a suitable compound enzyme composition with a synergy effect. CONSTITUTION: A method for regenerating corrugated cardboard waste is characterized in that it uses a compound enzyme containing at least two or more of the enzymes selected from cellulase, hemicellulase and amylase based enzymes. The compound enzyme is contained at 0.01-0.1wt.% based on total dry weight of the corrugated cardboard waste. The compound enzyme activates at 40-70°C and under the pH values of 4.0-8.0 to increase the strength and the dehydrating load and minimize white water contamination to result in the improved quality of regenerated product and productivity.

Abstract translation: 目的：开发瓦楞纸板废纸的再生方法，通过使用具有协同效应的合适的复合酶组合物，有效提高纸板的强度和脱水性能。 构成：用于再生瓦楞纸板废料的方法的特征在于其使用含有选自纤维素酶，半纤维素酶和淀粉酶的酶中的至少两种或更多种酶的复合酶。 复合酶的含量基于瓦楞纸板废物的总干重为0.01-0.1重量％。 复合酶在40-70℃下，在4.0-8.0的pH值下活化，以提高强度和脱水负荷，最大限度地减少白水污染，从而提高再生产品的质量和生产率。

Abstract: PURPOSE: A method for recycling old corrugated container by treating old corrugated container using amylase-based enzyme is provided, thereby accelerating dehydration of reclaimed paper material capable of improving quality and productivity of corrugate board. CONSTITUTION: In a method for recycling old corrugated container, 0.01 to 0.1% by weight of amylase-based enzyme based on the total weight of dry old corrugated container is introduced into waste paper material. The amylase-based enzyme is α -amylase-based enzyme obtained from Bacillus licheniformis or Bacillus subtilis alone or mixtures thereof in a weight ratio of 1:9 to 9:1.
