English term or phrase: black liquor

Definition from Wikipedia:
Black liquor is a byproduct of the kraft process, (also known as kraft pulping or sulfate process) during the production of paper pulp. Wood is decomposed into cellulose fibers (from which paper is made), hemicellulose and lignin fragments. Black liquor is an aqueous solution of lignin residues, hemicellulose, and the inorganic chemicals used in the process.

Example sentence(s):

Black liquor (BL), a by-product of the chemical pulping process, is an important liquid fuel in the pulp and paper industry. It contains almost all of the inorganic cooking chemicals along with the lignin and other organic matter separated from the wood during pulping in the digester. LULEÅ UNIVERSITETSBIBLIOTEK
Sometimes, people just need to make the best with what they have got to work with. This is what paper mills are trying to do by burning the "black liquor" waste which is a leftover remnant of chemicals and the lignin. As part of the Kraft process, the leftovers are burned to create steam which turns large generators, which in turn provide electricity for the plant. AutoblogGreen
The black liquor waste stream is converted from the paper pulping process into synthesis gas. The synthesis gas can then be processed into a variety of fuels—likely dimethyl ether (DME) and methanol (MeOH), although fuels such as Fischer-Tropsch diesel (FTD), Synthetic Natural Gas (SNG), or hydrogen are also possible.

黑液

Definition:
　　在烧碱法、硫酸盐法制浆过程中，大约有50%的纤维原料物质溶解于蒸煮液中，因其颜色较深，称为黑液。
　　黑液大约有30%~35%的无机物，主要成份是氢氧化钠、碳酸钠、硫化钠、硫酸钠和有机物结合的其他钠盐。有65%~70%的有机物质，主要成份是木素、树脂、淀粉及低分子化合物等。

Example sentence(s):

造纸业带来的环境污染曾长期困扰着人们。造纸废水中，黑液是主要的污染源。造纸黑液直接排放到河流海洋里,会造成局部水域富营养化,破坏原有的生态平衡。它因此而背上了污染环境的恶名。 - 中华人民共和国科技部
将制浆黑液经化工过程处理，以回收化学品和热能，再供制浆生产使用的过程。简称碱回收。黑液是植物纤维原料在蒸煮成浆后，从纸浆中分离出被蒸煮药液溶解出来的木素和糖类等有机化合物的碱性溶液及残余的蒸煮液。 - 互动百科
将木片，秸秆等原料蒸煮打碎漂白，就成了纸浆，而这个过程中产生的废水就叫造纸黑液黑液中含木质素、半纤维素以及木糖、钾、氮、磷等物质，在工、农业生产中都是有很高利用价值的。特点嘛，也就是含各类物质咯，还有就是造纸（非制浆）过程中的废水（叫白水）强酸或者强碱 - 百度知道
