“…Renewable agriculture residues and processing together with forest industry produce annually billion tons of cellulosic biomass. [14] Among furan derivatives, furfural (FF) and 5hydroxymethylfurfural (HMF) are the most utilized cellulosic sugar-derived platform molecules in renewable chemistry. They are commonly produced via acid-catalyzed dehydration of pentose and hexose sugars, respectively.…”

The depletion of finite primary fossil fuels we are facing makes necessary a deep metamorphosis in fundamental parts of the chemical industry. A progressive transition from petro‐based starting materials toward renewable biomass‐derived sources will have to take place in the synthesis of added‐value chemicals, important for our everyday life, such as pharmaceuticals, polymers, agrochemicals etc. Moreover, greener processes, carried out under friendlier reaction conditions, must be designed to address current concerns about the climate change and the resulting pressing need to reduce the environmental footprint of chemical processes. To this end, organocatalysis could offer a valuable opportunity for upgrading biomass‐derived platform molecules in line with the principles of Green Chemistry. This review presents some of recent and remarkable advancements in this emerging area. Organocatalysis has proven to be an efficient tool to transform low value bio‐based renewable platform building blocks into new high value bio‐based chemicals, with potential applications as synthetic intermediates, innovative materials and pharmaceutically active compounds.

Plastics displaying many merits have been indispensable in daily life and they still maintain the strong momentum of development. Nevertheless, petroleum-based plastics possess a stable polymer structure and most of them are incinerated or accumulated in the environment, leading to devastating impacts on our ecology system. Thus, exploiting renewable and biodegradable materials to substitute or replace these traditional petroleum-derived plastics is an urgent and important task. In this work, renewable and biodegradable all-biomass cellulose/grape-seed-extract (GSEs) composite films with high transparency and anti-ultraviolet performance were fabricated successfully from pretreated old cotton textiles (P-OCTs) using a relatively simple, green, yet cost-effective, approach. It is proved that the obtained cellulose/GSEs composite films exhibit good ultraviolet shielding performance without sacrificing their transparency, and their UV-A and UV-B blocking values can reach as high as nearly 100%, indicating the good UV-blocking performance of GSEs. Meanwhile, the cellulose/GSEs film show higher thermal stability and water vapor transmission rate (WVTR) than most common plastics. Moreover, the mechanical property of the cellulose/GSEs film can be adjusted by the addition of a plasticizer. Briefly, the transparent all-biomass cellulose/grape-seed-extracts composite films with high anti-ultraviolet capacity were manufactured successfully and they can be used as potential materials in the packaging field.

As a nonfood crop, sweet sorghum has been extensively utilized for sugar production and biomass energy conversion. However, industrial production generates a significant amount of sweet sorghum skin. Although paper and cellulose-based films are commonly prepared through a bottom-up approach to capitalize on their abundant cellulose content. The bottom-up approach often involves the use of substantial quantities of chemical reagents, thereby posing a serious threat to environmental safety. In this study, inspired by the arrangement of traditional Chinese house roof tiles, we employed a stacking and hot-pressing preparation strategy to transform sweet sorghum skins into flexible sweet sorghum films (SF). SF retained the high degree of orientation of cellulose while obtaining high strength and toughness along with excellent light transmission properties. In particular, the mechanical properties of SF in the direction parallel to the fibers are exceptionally remarkable. The tensile strength measured 796.4 MPa, while the toughness stands at 7.63 MJ/m3. Additionally, SF exhibited outstanding optical characteristics, boasting a remarkable light transmission of 78% and a haze of 60%. Moreover, we established the feasibility of utilizing SF as a functional material for various applications, showcasing its potential for optical management, smart wearables, and electronic devices. Importantly, the successful preparation of large-size SF unlocked possibilities for their widespread and large-scale utilization, thus making a valuable contribution to environmental sustainability.
