Technological Limitations

Once a biorefinery is ready to operate, the main processed materials need to be completely evaluated in terms of many different factors, including disposal regulations, technological limitations of installation, the market, and other societal considerations. In biorefinery, glycerol is the main by-product, representing around 10% of biodiesel production. In the last few decades, the large-scale production of biodiesel and glycerol has promoted research on a wide range of strategies in an attempt to valorize this by-product, with its transformation into added value chemicals being the strategy that exhibits the most promising route. Among them, C3 compounds obtained from routes such as hydrogenation, oxidation, esterification, etc. represent an alternative to petroleum-based routes for chemicals such as acrolein, propanediols, or carboxylic acids of interest for the polymer industry. Another widely studied and developed strategy includes processes such as reforming or pyrolysis for energy, clean fuels, and materials such as activated carbon. This review covers recent advances in catalysts used in the most promising strategies considering both chemicals and energy or fuel obtention. Due to the large variety in biorefinery industries, several potential emergent valorization routes are briefly summarized.

The increasing oil demand and exhaustion of reserves have initiated stimulus to search for new and sustainable sources of fuels and fine chemicals. Lignocellulosic biomass turned out to be a promising and renewable feedstock for these applications. 5-hydroxymethylfurfural (HMF) is one of the most promising building blocks for bio-based chemicals that can be derived from lignocellulosic biomass which can be potentially applied for large scale production. However, one of the main factors holding its transition is the need for sustainable, green and financially feasible processes. This review provides the studies made towards catalytic systems used for HMF production, as well as the various solvents and heating system applied. Research efforts to unravel the interactions among catalysts, solvents, and heating systems are encouraged, thereby engineering a synergistic conversion system for biomass valorization.

3D Weaving

Abstract There have been many publications on “3D Weaving”, and there are numerous patents on a variety of devices that may be used to make a “3D Woven” structure. The majority of the 3D woven products that are currently commercially available are formed by a 2D weaving process that is used to build up a preform with fibers oriented in three dimensions. Recent advances have lead to multiple insertion 3D weaving, i.e. 3D fabric formation with each process cycle, or multi-layers at one time. The 3Weaving™ process is a multiple insertion 3D weaving technology that is different from traditional weaving. These distinctions about the different processes will be detailed in this paper. Additionally, the economics, manufacturing and performance of 3D woven textile preforms for composites will be discussed. Problems and solutions in each of these areas that prevent the large scale production of advanced composites will be presented. The advantage of 3D textile preforming is the ability to take complexity and labor out of manually intensive and expensive composites fabrication processes, and put it in the relatively inexpensive automated preforming process.

Considerable amount of research is going on the role of plant species that exhibit anti-cancer properties. One such plant species is turmeric, which has been used in the human diet for centuries. The main active component/polyphenol in turmeric is curcumin. Recently, curcumin has been considered for cancer therapy. The initial challenge with curcumin is its large-scale production and purification of curcuminoids from turmeric. Most of the strategies are not fully effective due to the involvement of many organic solvents, time consumption, and inadequate separation between similar derivatives and crystal structures. Some of the methods to avoid using organic solvents are explained in this entry. The second challenge is that the isolated curcumin is unstable under various environmental and physiological conditions and degrades easily. Various strategies have been proposed and investigated to improve its aqueous solubility, stability, bioavailability, and potential therapeutic applications. Among them, nanoformulation is utilized to fill the gaps between clinical application and production. This review summarizes recent advances in curcumin's large-scale production and purification protocols, the necessity of nanoformulation, recent patents, and its anti-cancer mechanism. Emphasis is given on applying safe and green-tech methods of nanoformulation, including Mozafari and Heating methods.
