Examples include mulching films\u2014used to <strong>protect crops<\/strong> and suppress weed growth\u2014as well as the ties and clips used to support plants. In some applications, fragments of these materials may remain in the soil, contributing to <a href=\"https:\/\/resoilfoundation.org\/en\/environment\/microplastics-europe-at-risk-target-2030\/\" target=\"_blank\" rel=\"noopener\">microplastic contamination.<\/a><\/p>\n<blockquote><p>SOUL focuses on <a href=\"https:\/\/resoilfoundation.org\/editoriali\/bioprodotti-vantaggi-agricoltura\/\" target=\"_blank\" rel=\"noopener\">products<\/a> that deliver the necessary performance during use while offering more sustainable end-of-life management solutions.<\/p><\/blockquote>\n<p>The project encompasses 11 innovative products, including <strong>mulching films,<\/strong> coatings for controlled-release fertilizers, <strong>agricultural clips<\/strong> and ties, pheromone dispensers, turf reinforcement netting, tree guards for saplings, and infill materials for sports fields.<\/p>\n<p>A common feature is their high content of renewable raw materials\u2014at least 95%, according to the project\u2019s objectives. The resources used are derived from agricultural residues, by-products of the agri-food industry, and low-impact crops grown on marginal land.<\/p>\n<p>The ambition is twofold: <strong>to reduce reliance on fossil-based raw materials<\/strong> and to improve the management of products at the end of their life cycle. Depending on the specific application, the proposed solutions include soil biodegradation, composting, reuse, or recycling.<\/p>\n<div class='avia-iframe-wrap'>\n<blockquote class=\"wp-embedded-content\" data-secret=\"QSUbC7oxIQ\"><p><a href=\"https:\/\/resoilfoundation.org\/en\/agricultural-industry\/polyethylene-mulches-negative-effect\/\">Polyethylene mulches leave behind &#8216;negative effects for decades&#8217;<\/a><\/p><\/blockquote>\n<p><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"\u201cPolyethylene mulches leave behind \u2018negative effects for decades\u2019\u201d \u2014 Re Soil Foundation\" src=\"https:\/\/resoilfoundation.org\/en\/agricultural-industry\/polyethylene-mulches-negative-effect\/embed\/#?secret=Leq4nfLjpi#?secret=QSUbC7oxIQ\" data-secret=\"QSUbC7oxIQ\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe><\/div>\n<h5>Innovative materials, yet compatible with existing technologies<\/h5>\n<p>One of the most significant challenges concerns the feasibility of producing these new materials using technologies already available within the plastics industry.<\/p>\n<p>For this reason, the project involves both research centers and companies specializing in the development and processing of biomaterials.<\/p>\n<p>Novamont, CSIC, EVOenzyme, and AITIIP are working on refining the <strong>new formulations,<\/strong> sharing scientific expertise and experimental results.

Furthermore, a material\u2019s ability to biodegrade must be evaluated under the specific <strong>environmental conditions expected<\/strong> during its use and at the end of its life cycle, while also ensuring there are no unintended ecotoxic effects.<\/p>\n<p>For this reason, SOUL dedicates a significant portion of its activities to <strong>evaluating biodegradation, ecotoxicity,<\/strong> and the impact on soil fertility.<\/p>\n<p>Normec OWS has begun analyzing samples of biomaterials provided by the project partners, while AIMPLAS is developing a tool to model and predict how these materials behave during the biodegradation process.<\/p>\n<p>The project also follows the &#8220;Safe and Sustainable by Design&#8221; approach, which integrates <strong>safety and sustainability considerations<\/strong> from the very earliest stages of design. These evaluations include a Life Cycle Assessment (LCA) to examine the environmental impacts of the solutions being developed.<\/p>\n<p>The goal is to ensure that replacing conventional plastics with new materials does not simply shift environmental impacts from one stage of the <strong>production cycle<\/strong> or <strong>end-of-life phase<\/strong> to another.<\/p>\n<h5>Five countries to put new products to the test<\/h5>\n<p>Following an initial year primarily dedicated to <strong>developing materials<\/strong> and defining verification protocols, SOUL is preparing for a new phase: testing under real-world conditions.<\/p>\n<p><strong>Five demonstration sites<\/strong> are planned\u2014in Italy, Spain, Portugal, Poland, and Ireland\u2014where the performance of the products will be evaluated across various environmental and operational contexts.<\/p>\n<p>The <strong>validation program<\/strong> is coordinated by the Polish institute IUNG (Institute of Soil Science and Plant Cultivation). A detailed testing plan will be finalized in the coming months, with input from the project\u2019s consortium partners.<\/p>\n<p>These trials will make it possible to assess <strong>how the materials perform<\/strong> in their intended applications and to gather data essential for evaluating their potential for future commercialization.<\/p>\n<h5>A European network connecting research, businesses, and farmers<\/h5>\n<p>SOUL goes beyond mere technological development. The project also aims to foster dialogue among researchers, businesses, farmers, policymakers, and other stakeholders interested in innovation within the bioeconomy.<\/p>\n<p>To this end, a Multi-Actor Advisory Panel (MAP) was established; this consultative group held its first meeting in September 2026. The panel serves as a channel for gathering input and observations from parties outside the consortium, helping to steer product development toward addressing concrete needs.<\/p>\n<p><strong>Re Soil Foundation &#8211; <\/strong>a project partner responsible for communication, dissemination, training, and stakeholder engagement &#8211; presented the results of initiatives carried out during the first year at the meeting in Madrid.<\/p>\n<p>Meanwhile, the <a href=\"https:\/\/bioeconomybureau.eu\/\" target=\"_blank\" rel=\"noopener\">European Bioeconomy Bureau<\/a> monitors the evolution of European policies concerning the bioeconomy and innovative materials. Last May, it helped organize the project\u2019s first workshop in Brussels, which focused on sector-specific policies.<\/p>\n<p>Coordinated by the Spanish organization Fundaci\u00f3n AITIIP and supported by the Circular Bio-based Europe Joint Undertaking (CBE JU)\u2014with co-funding from the European Union\u2014SOUL brings together 17 European partners and one Swiss associate partner.<\/p>\n<p>The <strong>challenge<\/strong> for the coming years will be to demonstrate that materials derived from renewable resources can deliver adequate industrial performance, reduce the environmental footprint of products, and help prevent soil contamination.<\/p>\n<p>If confirmed through testing and environmental assessments, this outcome could <strong>open up new opportunities<\/strong> for the use of bioplastics in agricultural activities and other sectors where recovering materials after use remains a significant challenge.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The European project SOUL has concluded its first year of activity.
