This breakthrough is useful for <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>lications in the food, pharmaceutical, and biofuel industries.<\/p>\n<p>The production of each by-product depends on variations in temperature and pH, following a decomposition sequence that starts with phenolic compounds, passes through sugars, and ends with organic acids.<\/p>\n<p>The results showed a significant recovery: subcritical hydrolysis was able to obtain phenolic compounds ranging from 16.06 milligrams to 76.82 milligrams of gallic acid equivalent per gram (the standard for quantifying phenolic compounds). In contrast, acid hydrolysis obtained 12.76 milligrams of gallic acid equivalent per gram.<\/p>\n<p>In the case of sugars (glucose, xylose, and cellobiose), 448.54 milligrams were obtained per gram of corn stover hydrolyzed at 170 \u00b0C for a maximum of 30 minutes at a pH of 1. Traditional hydrolysis methods do not exceed 74.5 milligrams per gram of hydrolyzed stover. Thus, the yield increases six-fold while reducing time and energy costs.<\/p>\n<p>Finally, in the case of organic acids (acetic and formic), 1,157.19 milligrams were obtained per gram of hydrolyzed corn stover at 226 \u00b0C and a pH of 4.5. &#8220;This extraction of organic acids represents a concrete opportunity for producing renewable chemical precursors for use in biodegradable plastics, solvents, and natural preservatives,&#8221; says T\u00e2nia Forster-Carneiro, Rosa&#8217;s advisor, co-author of the article, and professor at UNICAMP&#8217;s School of Food Engineering (FEA).<\/p>\n<p>                                                                                                        <!-- TechX - News - In-article --><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Sustainable_method\"><\/span>Sustainable method<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The researchers also carried out a sustainability analysis of the <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">technology<\/a>, called EcoScale.

Other processes that use aggressive chemicals, such as sulfuric acid and sodium hydroxide, scored between 54.63 and 85.13 points.<\/p>\n<p>According to the scientist, another novel aspect of the study was the preliminary technical-economic analysis (or payback rate), which integrated experimental data with estimates of investments, operations, and economic returns. This analysis took into account factors such as the cost of equipment, inputs, and energy.<\/p>\n<p>&#8220;The analysis provides a strategic vision for decision-making, simulates different scenarios, and identifies the most promising ones for industrial application, strengthening the link between <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">science<\/a>, innovation, and practical application,&#8221; explains Forster-Carneiro.<\/p>\n<p>The work focused on sugar as the end product with the greatest economic value for biofuels. The results showed a payback period of between four and five years.<\/p>\n<div class=\"article-main__more p-4\">\n<p><strong>More information:<\/strong><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\tRafael Gabriel da Rosa et al, Valorizing corn stover waste into valuable bioproducts using subcritical water hydrolysis, <i>Biofuel Research Journal<\/i> (2025). <a rel=\"nofollow\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.18331\/BRJ2025.12.1.2\" target=\"_blank\">DOI: 10.18331\/BRJ2025.12.1.2<\/a><\/p>\n<\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>\n                                                <strong>Citation<\/strong>:<br \/>\n                                                Green technology uses corn stover to produce high-value bioderivatives and generate savings (2025, May 30)<br \/>\n                                                retrieved 30 May 2025<br \/>\n                                                from https:\/\/techxplore.com\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2025-05-green-technology-corn-stover-high.html\n                                            <\/p>\n<p>\n                                            This document is subject to copyright.
