淡水藻类生物量和橙子和柠檬皮作为组织纸浆补充剂进行了评估。藻类生物量的纤维素和半纤维素含量分别为7.1%和16.3%，而柑橘皮的纤维素含量为12.7%至13.6%，半纤维素为5.3%至6.1%。对于所有材料，木质素和灰分含量为2%或更低，使得它们适合用作纸浆补充剂。在纸浆中添加藻类生物质显著提高了纸浆的机械强度。然而，亮度受到叶绿素的不利影响。在纸浆中添加柑桔皮对纸张的裂断长没有影响，但耐破度提高，撕裂度降低。亮度在10%的比例下受到负面影响，因为柑橘皮颗粒表现为有色颜料。这两种材料的成本比传统纸浆低约45%，从而在将它们添加到纸浆中后，最终纸张价格降低0.9-4.5%。(c)2006爱思唯尔有限公司保留所有权利。
Freshwater algal biomass and orange and lemon peels were assessed as tissue paper pulp supplements. Cellulose and hemicellulose contents of algal biomass were 7.1% and 16.3%, respectively, whereas for citrus peels cellulose content ranged from 12.7% to 13.6% and hemicellulose from 5.3% to 6.1%. For all materials, lignin and ash content was 2% or lower, rendering them suitable for use as paper pulp supplements. The addition of algal biomass to paper pulp increased its mechanical strength significantly. However, brightness was adversely affected by chlorophyll. The addition of citrus peels in paper pulp had no effect on breaking length, increased bursting strength and decreased tearing resistance. Brightness was negatively affected at proportions of 10%, because citrus peel particles behave as coloured pigments. The cost of both materials is about 45% lower than that of conventional pulp, resulting in a 0.9-4.5% reduction in final paper price upon their addition to the pulp. (c) 2006 Elsevier Ltd.
