“…Notably, since glycerol typically requires additional production operations (i.e., as a byproduct of the biodiesel production process), the use of freely available biomass as a feedstock may be a more sustainable strategy. The literature reveals that (non-fossil) AA may be produced from biomass via stepwise processes, involving an initial LA acid production step (via sugar fermentation) followed by LA dehydration (i.e., fermentation-dehydration or FD pathway) [23][24][25]. The current study proposes an alternative "syngas pathway" that incorporates the conversion of biomass to (→) propylene → AA (i.e., thermochemical-fermentation-oxidation or the TFO pathway).…”

The global demand for acrylic acid (AA) is increasing due to its wide range of applications. Due to this growing demand, alternative AA production strategies must be explored to avoid the exacerbation of prevailing climate and global warming issues since current AA production strategies involve fossil resources. Investigations regarding alternative strategies for AA production therefore constitute an important research interest. The present study assesses waste apple pomace (WAP) as a feedstock for sustainable AA production. To undertake this assessment, process models based on two production pathways were designed, modelled and simulated in ASPEN plus® software. The two competing production pathways investigated included a process incorporating WAP conversion to lactic acid (LA) prior to LA dehydration to generate AA (denoted as the fermentation–dehydration, i.e., FD, pathway) and another process involving WAP conversion to propylene prior to propylene oxidation to generate AA (denoted as the thermochemical–fermentation–oxidation, i.e., TFO, pathway). Economic performance and potential environmental impact of the FD and TFO pathways were assessed using the metrics of minimum selling price (MSP) and potential environmental impacts per h (PEI/h). The study showed that the FD pathway presented an improved economic performance (MSP of AA: USD 1.17 per kg) compared to the economic performance (MSP of AA: USD 1.56 per kg) of the TFO pathway. Crucially, the TFO process was determined to present an improved environmental performance (2.07 kPEI/h) compared to the environmental performance of the FD process (8.72 kPEI/h). These observations suggested that the selection of the preferred AA production pathway or process will require a tradeoff between economic and environmental performance measures via the integration of a multicriteria decision assessment in future work.

“…After harvesting, the sugarcane plant (Saccharum officinarum) is crushed between the serrated rollers in the mill. The cellulose and hemicellulose comprise around 70 % of the sugarcane bagasse [19]. Bagasse fibers are gaining acceptance from many researchers as they can be used as a reinforcement material in composite preparation [13].…”

In spite of the fact that a prodigious portion of petroleum covers multitudinous products in the commercial world, its nonbiodegradable characteristic is an unenviable factor. The utilization of biodegradable polymers or biopolymers is a prominent alternative to petroleum-based plastic products. Reinforcing natural fibers to biopolymer matrices significantly improves the properties of prepared plastic products. Such biopolymer composites have been developed by researchers to provide environmentally responsible materials and thereby reduce carbon footprint. Modification or functionalization of natural fibers is important to ameliorate the interfacial bonding with biopolymers, and to successfully obtain high-performance composite materials that can compete with conventional petrochemical-based polymer composite counterparts. Another widely accepted composite development technique is by combining different types of fibers into a single matrix to develop highly valued hybrid composites. The review focuses on the extraction, processing and characterization of bio-based materials; natural fibers and biopolymers, and their synergistic application and future scope as biopolymer composites in automotive and other growing sectors.

“…The biomass fractions like cellulose, hemicellulose, and lignin can be chemically modified for the generation of several bioproducts. As a result, cellulose acetate, carboxymethylcellulose, methylcellulose, and furfural and phenol resins can be obtained (Resende and da Costa, 2019). The ethanol produced in both first-and second-generation platforms can be dehydrated and polymerized for the production of green plastic as an alternative to petroleum-based products (Confente et al, 2019).…”

The integrated approach in biorefinery mainly involves the utilization of various agroindustrial byproducts such as raw materials for the production of several biobased products like biofuels, bioenergy, and other high-value chemicals. Biofuels are the backbone of biorefineries, however, production of value-added biomolecules such as biopigments, biopolymers, biosurfactants, and nutritional yeast has been attracting great attention. The production of these biomolecules using traditional approaches has been extensively studied in the last few years owing to their promising application in different industries such as chemical, food/feed, and pharmaceuticals for the development of novel products for mankind. Moreover, the production of such biomolecules using lignocellulosic, starchy, and some other agroindustrial byproducts is still not fully explored. Hence, there is a huge scope in the development of sustainable biorefining approaches to make the technology cost-effective. The lignocellulosic biomasses usually used in biorefineries are mainly composed of cellulose, hemicellulose, and lignin, whereas starchy materials, besides starch, usually contain, protein, lipids, and some micronutrients. The processing of these biomasses through successive steps like pretreatments, enzymatic hydrolysis, and fermentation is essentially required to obtained final biobased products. Considering certain bottlenecks of above-mentioned conventional biorefineries approaches, new technologies have been proposed for the improved pretreatment of biomass and efficient enzymatic hydrolysis in order to minimize the concentration of toxic inhibitors in resulting hydrolysate. In this review, we highlighted the different agroindustrial byproducts and their applications for the production of valuable biorefinery products.
