When fibers or fiber containing material are lost, valuable and scarce material is being lost and thrown away. In addition, costs also increase, since besides the raw material loss, there is a residue to handle, to transport and to dispose away. This residue is also called pollution. For this reason, generating fibrous solid wastes in pulp mills is a great ingenuousness, impacting on our costs and on nature.

The measures adopted in some countries for their eradication or to control their propagation are expensive, have been considered unfeasible from practical and economical perspectives, and have generated large amounts of residue that must be valorized in a sustainable way. This review brings together information on the valorization of bark, wood, leaves, flowers, pods, seeds, roots, and exudates from Acacia spp., through the production of high-value bioactive extracts (e.g., antioxidant, antimicrobial, anti-inflammatory, antidiabetic, antiviral, anthelmintic, or pesticidal agents, suitable to be explored by pharmaceutical, nutraceutical, cosmetics, and food and feed industries), its incorporation in innovative materials (e.g., polymers and composites, nanomaterials, low-cost adsorbents), as well as through the application of advanced thermochemical processes (e.g., flash pyrolysis) and pre-treatments to decompose biomass in its structural components, regarding the production of biofuels along with valuable chemicals derived from cellulose, hemicellulose, and lignin.

    PEER-REVIEWED REVIEW ARTICLE bioresources.com BIOCONVERSION OF KNOT REJECTS FROM A SULPHITE PULP MILL TO ETHANOL Xiao Zhang,a.b Maobing Tu, c Michael Paice, a George Sacciadis, a Zhihua Jiang, a Naceur Jemaa, a and Alain Thibault a Knot rejects obtained from pulp screening after sulphite pulping are difficult to dewater, which makes landfilling expensive and burning inefficient. The rejects were found to contain up to 50% cellulose, which is very susceptible to enzymatic hydrolysis to glucose. Knot rejects were hydrolyzed at 20% consistency in a laboratory peg mixer with cellulase enzyme. The thick slurry was liquefied within the first hour of mixing and resulted in a glucose concentration of over 100 g/L after 24 hours of reaction. This solution was fermented by yeast to give an ethanol concentration of over 5%. The laboratory results were confirmed at pilot scale with a mortar mixer (high consistency) or stirred tank reactor (medium consistency) at the 400 L and 6000 L scales, respectively. It was found that washing the knots with ammonia resulted in increased glucose conversion. Enzyme costs could be lowered by separating the enzyme from the hydrolyzed sugars by membrane ultrafiltration and recycling the enzyme to the subsequent batch of substrate. The combination of high-consistency hydrolysis and enzyme recycling minimizes capital investment, energy requirements, and enzyme costs, which are significant factors in the overall economic viability of cellulose conversion to ethanol.

  • Lan Su Garden Plant Talks Edgeworthia Chrysantha​邊緣菊花
    Lan Su Garden Plant Talks 邊緣菊花 Edgeworthia chrysantha​ ​ ​(biānyuán júhuā) Elizabeth Cha Smith (March 15, 2018) “Had I been born Chinese, I would have been a calligrapher, not a painter.” - Pablo Picasso (1965) Edgeworthia in Lan Su In our garden, volunteers know ​Edgeworthia chrysantha​ as the “Chinese paper bush” or just “paper bush.” Starting in early January, we start to notice its button-like green buds in Bed #20S behind the gift shop, and by early February we see them turning into golden yellow flower heads dangling at the tips of ternate (three-pronged) branches that extend from naked base branches. Edgeworthia is also known as “yellow daphne” because these plants belong to the same family and have similar fragrances and flowers. The combination of edgeworthia’s small, delicate yellow flower clusters and their gentle fragrance is a delightful surprise for our visitors, and it is really nice to know that the blooming will continue for several more weeks while we are still in winter mode. Although the symbolic value of edgeworthia in Chinese culture is not clear to me, I did read about how its flowers, bark, and roots have been used in folk medicine for their anti-inflammatory and analgesic properties and to treat ocular diseases as well as insomnia and depression. Chasing a Paper Trail Because of edgeworthia’s most common name, “paper bush”, I was interested in learning more about how the Chinese and other cultures used it to make paper. Imagine my surprise when I read ​The Paper Trail​ (a highly regarded monograph on the history of paper) and found that the author, Alexander Monro, does not mention edgeworthia once in his almost 400 page book! Despite my difficulty in finding out more about whether or how Chinese used edgeworthia in paper-making, archeologists/historians have known for a long time that the Chinese first invented more primitive forms of paper during the second century BCE using hemp (European paper-making dates to the 16th century).
