摘要： Disclosed is a formulation and method for treating paper so that paper in landfills produces less methane than untreated paper. The method includes adding one or more nitrate salts to paper during the process of making paper, or after the paper is made. One effect of adding the nitrate salts is promoting the growth of certain bacteria which do not produce methane as they consume paper products.

摘要： The invention is a method of making a wet formed, sheeted, readily reslurriable sheeted crosslinked cellulose and the products made by the method. Crosslinked wood pulp fibers tend to be quite brittle. If crosslinked while in sheeted form, the sheets cannot be readily defibered, either in a wet or dry state, without serious fiber degradation. The sheet products of the present invention can be easily redispersed or repulped in water without significant fiber breakage. The present products are made by including within the sheet, while still in wet form, a debonding or softening agent which is preferably added before the latent crosslinking reactant. Most preferably the debonder is added prior to the headbox of a paper machine and the crosslinking reactant is applied near the end of the forming wire or at the press section. The treated sheet is dried conventionally. Crosslinking may occur entirely during drying or during a period of additional heating, usually at a temperature in excess of 100.degree. C. for a short period of time. Conventional debonding agents and crosslinking reactants are suitable. The softening agent apparently reduces or prevents adhesive bonding between adjacent fibers caused by polymer formation external to the fiber under reaction conditions.
摘要翻译：本发明是一种制成湿成型，片状，易于再生的片状交联纤维素和通过该方法制备的产品的方法。交联的木浆纤维往往是相当脆的。如果以片状形式交联，则在湿或干的状态下，片材不能容易地脱纤维，而不会严重的纤维降解。本发明的片状产品可以容易地再分散或重新分配在水中而不会明显的纤维断裂。本产品通过在片状物中包含湿态形式，优选在潜在交联反应剂之前加入的脱粘剂或软化剂制成。最优选地，脱纸器在造纸机的流浆箱之前添加，并且交联反应物被施加在成形丝的端部附近或在压榨部分处。经处理的片材是常规干燥的。交联可能在干燥期间或在额外加热期间完全发生，通常在超过100℃的温度下短时间内完成。常规脱粘剂和交联反应物是合适的。在反应条件下，柔软剂明显降低或防止由纤维外部的聚合物形成引起的相邻纤维之间的粘结。
