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.
对淡水藻类生物质以及橙子皮和柠檬皮作为薄页纸纸浆补充剂进行了评估。藻类生物质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在12.7%至13.6%之间，半纤维素含量在5.3%至6.1%之间。对于所有材料，木质素和灰分含量均为2%或更低，这使得它们适合用作纸浆补充剂。向纸浆中添加藻类生物质显著提高了其机械强度。然而，亮度受到叶绿素的不利影响。向纸浆中添加柑橘皮对裂断长没有影响，增加了耐破度并降低了撕裂强度。当添加比例为10%时，亮度受到负面影响，因为柑橘皮颗粒起到了有色颜料的作用。这两种材料的成本均比传统纸浆低约45%，在将它们添加到纸浆中后，最终纸张价格降低了0.9 - 4.5%。
