This volume brings together the current research on all aspects of lignins, the second most abundant group of biopolymers. It covers recent progress in elucidating some of the more intractable aspects of lignin preparation. Among the topics covered in its 41 chapters are: various methods for studying the structure of lignins; discussions of polymer products derived from the modification of lignin; water-soluble polymers; organosolv pulping, wood adhesives, and enzymatic lignin modification; and various products from lignins, including polyols, polyurethanes, polyblends, grafts, epoxies, and acrylics.

While newsprint may not be the ideal material for long-term preservation due to its inherent acid, lignin, and other impurities, the 20x24" Broadsheet Flat Newspaper Kit provides a comprehensive solution for extending the lifespan of your valuable newspapers and magazines. This all-in-one kit is designed to simplify the process of newspaper and magazine storage, ensuring that your cherished items are kept in optimal conditions.The kit includes a drop front box, ten archival quality polyethylene bags, and a metal desiccant canister. The polyethylene bags provide the first layer of protection, safeguarding your newspapers from dust, moisture, and other environmental factors. The drop front box offers an additional layer of security, further shielding your items from potential damage. The metal desiccant canister aids in maintaining a dry environment within the box, helping to prevent the harmful effects of humidity.To maximize the effectiveness of this kit, it is recommended to store the box in a cool, dry environment such as an air-conditioned closet. Avoid areas with temperature and humidity extremes like basements or attics. Remember, if the environment is uncomfortable for you, it will likely be the same for your stored newspapers. When packing your newspapers, avoid overstuffing the box. Instead, pack them loosely to prevent unnecessary stress on the papers.If your newspapers hold significant historical or personal value, you may want to consider professional deacidification services. While this can be costly for large quantities, it can significantly enhance the lifespan of your newsprint. However, for most users, the 20x24" Broadsheet Flat Newspaper Kit offers a practical and effective solution for preserving newspapers and magazines, slowing down the inevitable yellowing and brittleness that comes with time.

After the sold-out cassette release of Stanza / Stanza II on Beacon Sound in 2015 (a co-release with Baro) and 2016's The Benoit Pioulard Listening Matter on Kranky, Seattle's Thomas Meluch returns with a brand new Benoit Pioulard album of ambient bliss. Floating on a plume of pure shoegaze, Lignin Poise conjures nature, specifically the waters and forests of the Cascadia bioregion, as ecstatic reverie. It is a work of deliberate renewal in a time of global tumult. A golden oasis of deep memory

One of the most significant challenges facing mankind in the twenty-first century is the development of a sustainable global economy. Within the scientific community, this calls for the development of processes and technologies that will allow the sustainable production of materials from renewable natural resources. Plant material, in particular lignin, is one such resource. During the annual production of about 100 million metric tons of chemical wood pulps worldwide, approximately 45 and 2 million metric tons/year of kraft lignin and lignosulfonates, respectively, are also generated. Although lignosulfonates have found many applications outside the pulp and paper industry, the majority of kraft lignin is being used internally as a low-grade fuel for the kraft pulping operation. A surplus of kraft lignin will become available as kraft mills increase their pulp production without expanding the capacity of their recovery boilers that utilize lignin as a fuel. There is a tremendous opportunity and an enormous economic incentive to find better uses of kraft lignin, lignosulfonates and other industriallignins. The pulp and paper industry not only produces an enormous amount of lignins as by­ products of chemical wood pulps, but it also utilizes about 10 million metric tons of lignin per year as a component of mechanical wood pulps and papers. Mechanical wood pulps, produced in a yield of 90-98% with the retention of lignin, are mainly used to make low-quality, non-permanent papers such as newsprint and telephone directories because of the light-induced photooxidation of lignin and the yellowing of the papers.
