“…Initially, the FD process that employs LA as a precursor to AA via its dehydration was investigated according to the simplified process flow diagram presented in Figure 1. LA production was based on similar techniques described in [42]. Figure 1 shows that initially, the water content of the WAP is reduced to 50 wt.% from 67 wt.% (Materne company, Brussels, Belgium) via mechanical dewatering operations.…”

Waste Apple Pomace Conversion to Acrylic Acid: Economic and Potential Environmental Impact Assessments

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.

“…The valorization of apple pomace in an integrated biorefinery draws more attention in the economic aspect since it is possible to obtain different products in the same facility with an integrated cascade valorization 134 . In an apple pomace‐based biorefinery for the multiproduction of 5‐hydroxymethylfurfural (5‐HMF), lactic acid and xylitol, efficient process design, modeling and simulation were performed 135 . Aiming to avoid unfavorable environmental outcomes while maintaining a minimum acceptable internal rate of return of 10%, a 0.64 mass fraction of the waste apple pomace must be processed to lactic acid while a 0.36 mass fraction of the apple must be processed to 5‐HMF (from C 6 sugars) and xylitol (from C 5 sugars).…”

Apple pomace can be used as feedstock in the production of propionic acid (productivity 8.01 g L −1 and yield 0.40 g g −1 ) using Propionibacterium freudenreichii .…”

This bibliometric study explored the scientific publications of apple waste over the period from 2000 to 2020, aiming to contribute to the sustainable development of the apple industry toward waste-biorefinery implementation, advocating a circular economy. The bibliometric study covered the publications' evolution, research areas, top-cited papers, international collaborative networks, top countries and journals. The results demonstrate that 628 documents (604 articles and 24 reviews) studied apple waste over the last 20 years, and the number of publications exponentially increased after 2010. The most used keywords revealed that the main studied topics in the field were associated with technologies to manage apple pomace, the main solid waste generated from juice production, demonstrating a research trend toward renewable energy and bio-based products. The bibliometric study indicated that the most productive countries are China, India and the USA. Apple waste could be an environmentally friendly feedstock for biorefinery design and implementation. The biorefinery could produce value-added products (polyphenols, pectin, sugars and essential oils) and bioenergy (ethanol, methane, electricity and heat) in different industrial arrangements. The main technological routes described in the literature have been associated with the production of lactic acid, xylitol, ethanol, bioactive compounds, xyloglucan, films, pectin, acetic acid, acetone-butanol-ethanol, emulsifiers and inulinase enzyme. In conclusion, this review contributes to the decision-making for the industrial implementation of a waste biorefinery, advocating circular economy transition based on the sustainable valorization of apple waste.
