“…Solid-state 13 C CP/MAS NMR analysis of a control xylan/sorbitol film, NCW and NCW/xylan nanocomposite films is shown in Figure 1. 13 C NMR chemical shifts of the starting xylan and NCWs agreed with literature values [34][35][36][37] and could be readily assigned in the spectra of the nanocomposite films. The 13 C CP/MAS NMR spectra of the NCWs showed the typical spectra of crystalline cellulose and based on the integration of the cellulose C 4 peak region, the NCWs had a crystallinity of ∼64%.…”

A xylan nanocomposite film with improved strength and barrier properties was prepared by a solution casting using nanocellulose whiskers as a reinforcing agent. The 13 C cross-polarization magic angle spinning (CP/MAS) nuclear magnetic resonance (NMR) analysis of the spectral data obtained for the NCW/xylan nanocomposite films indicated the signal intensity originating from xylan-cellulose interactions. Qualitatively, the spectral data obtained for the NCW/xylan nanocomposite films indicated that the amount of xylan adsorbed to cellulose increases with the addition of NCW. In an attempt to quantify this effect, non-linear least-squared spectral line fitting was used to deconvolute the adsorbed xylan peak at ∼82 ppm. The peak intensity ratio of adsorbed xylan peak and xylan C 1 peak, which represents the total amount of xylan increases suggesting that upon the addition of NCW, the amount of adsorbed xylan increases. In an effort to further infer the structure-property relationships associated with the observed strength and barrier properties, 1 H NMR T 2 relaxation experiments were also conducted to investigate the change in the nature of carbohydrate-water interactions as a result of NCW incorporation. Water adsorbed into the 50% nanocomposite film had significantly shorter relaxation times with respect to the control xylan/sorbitol and all other NCW/xylan nanocomposite films. Additionally, X-ray diffraction of the nanocomposite films showed increased levels of crystalline material in the nanocomposites due to NCW addition.

“…The use of natural fiber in the preparation of composite materials has recently attracted much attention because of its low cost and environmental friendliness (Bhattacharya et al 2008;Ku et al 2011;Liu et al 2006;Xie et al 2010). As a natural polymer, the use of natural fiber offers environmental advantages such as reduced dependence on nonrenewable sources (La Mantia and Morreale 2011), degradability, and suitability for combustion as part of a carbon-neutral cycle.…”

Natural fiber is a renewable resource characterized by its low cost and environmental friendliness. However, flame retardant properties are one of the biggest limitations for the preparation of composite materials that need to be improved. In this work, a novel complex flame retardant consisting of aluminum hydroxide (ALH) and decabromine diphenyl oxide (PBDE) was proposed to inhibit the thermal decomposition. Flameretarding paper was made from softwood pulp and complex flame retardant. The thermal properties of the flame retardants were studied using thermogravimetric analysis (TGA). The mechanical properties of paper treated at different temperatures were tested, while the surface characteristics of natural fiber were detected by a scanning electron microscope (SEM) and atomic force microscope (AFM); their specific surface areas were also measured. The optimum value of aluminum hydroxide to decabromine diphenyl oxide was 3 to 1, added at 70% based on dried natural fiber. It also had good flame retardant performance and mechanical properties at 200 °C for 5 min; meanwhile, the tensile index of the handsheet was 82.5 Nm/g, and the specific surface area was 0.414 m 2 /g.

“…Recently, an extensive review from Jonoobi, et al [286] detailed the different preparation methods for CNFs from various natural resources and residues. Agricultural resources and residues such as wheat straw and soy hulls [287,288], empty fruit bunches [289], sugar beet pulp [290], potato pulp [291], swede root [292], bagasse [293,294], rice straw [293], banana rachis [295] and banana peels [296], have been used as a raw material for the production of CNFs. The extraction is conducted by mechanical processes, e.g., high-pressure homogenization, grinding, refining treatments or by acid hydrolysis.…”

Abstract:The vast and ever-growing amount of agricultural and food wastes has become a major concern throughout the whole world. Therefore, strategies for their processing and value-added reuse are needed to enable a sustainable utilization of feedstocks and reduce the environmental burden. By-products of potato, tomato, cereals and olive arise in significant amounts in European countries and are consequently of high relevance. Due to their composition with various beneficial ingredients, the waste products can be valorized by different techniques leading to economic and environmental advantages. This paper focuses on the waste generation during industrial processing of potato, tomato, cereals and olives within the European Union and reviews state-of-the-art technologies for their valorization. Furthermore, current applications, future perspectives and challenges are discussed.
