“…Depending on their origin, they will have varying chemical compositions (typically with greater lignin and/or hemicellulose content than bast fibers) and degrees of crystallinity. An appealing aspect of these materials is that they are generally left-over byproducts from a crop primary purpose (e.g., sugar cane bagasse), presenting opportunities for more sustainable value creation for secondary portions of the plant …”

“…An appealing aspect of these materials is that they are generally left-over byproducts from a crop primary purpose (e.g., sugar cane bagasse), presenting opportunities for more sustainable value creation for secondary portions of the plant. 51 Physical and chemical treatments may be used to modify fibers prior to their introduction into a composite. They may be physically chopped to reduce the length and increase accessibility to cellulose.…”

As the global demand for plastics continues to grow, plastic waste is accumulating at an alarming rate with negative effects on the natural environment. The industrially compostable biopolymer poly(lactic acid) (PLA) is therefore being adopted for use in many applications, but the degradation of this material is slow under many end-of-life conditions. This Perspective explores the feasibility of accelerating the degradation of PLA through the formation of PLA-plant fiber composites. Topics include: (a) key properties of PLA, plant-based fibers, and biocomposites; (b) mechanisms of both hydrolytic degradation and biodegradation of PLA-fiber composites; (c) end-of-life degradation of PLA and PLA-plant fiber composites in aerobic and anaerobic conditions, relevant to compost, soil and seawater (aerobic), and landfills (anaerobic); and (d) sustainability and environmental impact of PLA and PLA-plant fiber composites, as evaluated using life cycle assessment. Additional degradation modes, including thermal and photodegradation, which are relevant during processing and use, have been omitted for clarity, as have other types of PLA biocomposites. Multiple studies have shown that the addition of some types of plant fibers to PLA (to form PLA biocomposites) accelerates both water transport in the material and hydrolysis, presenting a possible avenue for improving the end-of-life degradation of these materials. To facilitate the continued development of materials with enhanced biodegradability, we identify a need to implement testing protocols that can distinguish between different degradation mechanisms.

“…Cellulose, a polymer material with high aspect ratios, high toughness, low density, and low toxicity, is suitable for constructing flexible composite aerogel films. − Currently, researchers have prepared aerogel films from various cellulose sources including bacteria, plants, algae, and tunicates. − For example, Smalyukh et al prepared a highly transparent wood cellulose aerogel via colloidal self-assembly and procedures compatible with roll-to-roll processing . Waste transformation as the source of valuable materials is a more effective strategy than using commercial crops (e.g., wood, cotton, and bamboo) as raw materials for high-value valorization given socioeconomic and environmental protection. , As an agro-industrial byproduct resulting from sugar and alcohol industries, bagasse is one of the largest cellulose resources and appropriate for extracting cellulose at low cost (cellulose accounts for approximately 40–50 wt % of bagasse). − However, the inefficient treatments of bagasse, especially treated as industrial waste in the industry, not only waste this good cellulosic resource but also pollute the environment . Therefore, it is necessary to develop better extraction and reuse technologies for sugarcane cellulose from bagasse to further improve its economic value and reduce environmental pollution at the same time.…”

The preparation of functional composite aerogels for building envelopes, especially for building glazing as the key climate moderator, has been widely investigated to improve the sustainability of buildings. Unfortunately, the prohibitive costs, mechanical brittleness, and optical opacity limit the current development and application of composite aerogels. Herein, using the controllable extraction of cellulose from bagasse, a low-cost (less than $3 per square foot), flexible (>15% elastic deformation under 0.02 MPa) bagasse aerogel film with high visible-light transparency (>80% transmittance of visible light) and superinsulation (0.0158 W m–1 K–1) was developed. These properties were achieved by constructing a uniform three-dimensional network structure using elastic polysiloxane and a mixture of cellulose nanofibers and cellulose nanocrystals in an equal proportion. This cellulosic aerogel film would have the latent potential of application in highly glazed modern buildings to reduce the energy loss from windows.

“…Different pretreatment approaches have been adopted to disrupt lignocellulosic structures to enhance the accessibility of cellulose. These include physical, chemical, biological, and combined treatments. − The physical and chemical pretreatments reduce biomass recalcitrance and change the specific surface area, particle size, and degree of polymerization . However, they are limited by either long processing time, high energy demand, high cost, exposure to toxic chemicals, or environmental problems associated with chemical waste. , Biological pretreatments (such as enzymatic and whole-cell processes) are reported to increase both accessibility and purity of cellulose. , It remains the most eco-friendly method for cellulose extraction with regard to the principles of green chemistry.…”

Agroindustrial wastes are renewable sources and the most promising sustainable alternative to lignocellulosic biomass for cellulose production. This study assessed the electrothermal pretreatment of rambutan peel (RP) for producing cellulose fibers. The pretreatment was carried out by Ohmic heating at a solid-to-liquid ratio of 1:10 (w/v) in a water/ethanol (1:1, v/v) mixture as the electrical transmission medium at 60 ± 1 °C for different holding times (15, 30, and 60 min). Ohmic heating did not significantly influence the total fiber yield for the various holding times. However, the compositions of the samples in terms of extractives, lignin, hemicellulose, and α-cellulose content were significantly influenced. In addition, the electrothermal pretreatment method reduced the bleaching time of RP by 25%. The pretreated fibers were thermally stable up to 240 °C. Ohmic heating pretreatment times of 15 and 30 min were found most promising, reducing the required bleaching chemicals and increasing the α-cellulose yield. The pretreated bleached cellulose fibers had similar properties to nontreated bleached fibers and could be efficiently processed into stable gels of strong shear-thinning behavior with potential application as rheology modifiers in food products. Our results demonstrate that rambutan peel could serve as a promising sustainable alternative to woody biomass for cellulose production. Ohmic heating meets the requirements for industrial applications as it is eco-friendly, improves the efficiency and energy consumption in fiber processing, and could as well be included in the processing of similar food wastes.
