Core Objectives and Methodology

The primary objective of this research is to develop a sensitive, convenient, and reliable method to ensure the safety of recycled plastic products for consumer use. This directly supports the principles of a circular economy and sustainable production patterns.

• Problem Statement: Recycled plastics can contain impurities, including toxic residues and hazardous Volatile Organic Compounds (VOCs), which pose potential health risks and undermine consumer confidence.
• Proposed Solution: The project will develop a robust testing method to detect hazardous VOCs, thereby improving the quality and safety of recycled materials.

Analysis of Sustainable Development Goals in the Article

1. Which SDGs are addressed or connected to the issues highlighted in the article?

• SDG 3: Good Health and Well-being: The research aims to develop methods to test for toxic residues and hazardous chemicals (VOCs) in recycled plastics, directly addressing the health risks posed to consumers and workers. The article states, “Monitoring and reducing hazardous VOCs protects consumers and workers from health risks, contributing to healthier communities.”
• SDG 4: Quality Education: The grant provides hands-on research opportunities for undergraduate students at Troy University, enhancing their skills in analytical chemistry and strengthening the future STEM workforce. The article notes, “…provides valuable opportunities for Troy University undergraduate students to engage in hands-on research… and strengthen the STEM workforce.”
• SDG 8: Decent Work and Economic Growth: By improving the quality and safety of recycled plastics, the research is expected to boost their marketability, enhance the viability of the recycling industry, and create jobs. The article mentions that this work “enhances industry viability, creates jobs and fosters innovation.”
• SDG 9: Industry, Innovation, and Infrastructure: The project is centered on scientific research and technological innovation, funded by the National Science Foundation. It focuses on developing a new, sensitive, and reliable testing method (HS-SPME-GC-MS) to upgrade the technological capabilities of the plastics recycling industry.
• SDG 12: Responsible Consumption and Production: The core theme of the article is improving the safety and effectiveness of plastic recycling. This supports the environmentally sound management of waste, encourages higher recycling rates, and aims to reduce overall plastic waste generation, aligning with sustainable production and consumption patterns.
• SDG 14 (Life Below Water) and SDG 15 (Life on Land): By aiming to increase recycling rates, the research contributes to reducing the amount of plastic waste that ends up in landfills and ecosystems, which helps protect both terrestrial and marine environments from plastic pollution.

2. What specific targets under those SDGs can be identified based on the article’s content?

• Target 3.9: “By 2030, substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination.” The research directly supports this by developing a method to detect and monitor hazardous VOCs in recycled plastics, which are a source of chemical contamination.
• Target 4.4: “By 2030, substantially increase the number of youth and adults who have relevant skills, including technical and vocational skills, for employment, decent jobs and entrepreneurship.” The project provides undergraduate students with hands-on experience in “state-of-the-art analytical chemistry techniques,” which are relevant skills for the STEM workforce.
• Target 9.5: “Enhance scientific research, upgrade the technological capabilities of industrial sectors in all countries… encouraging innovation and substantially increasing the number of research and development workers…” The $534,194 grant from the NSF for “groundbreaking research” into a new testing methodology is a direct contribution to this target.
• Target 12.4: “By 2020, achieve the environmentally sound management of chemicals and all wastes throughout their life cycle… and significantly reduce their release to air, water and soil in order to minimize their adverse impacts on human health and the environment.” The research focuses on detecting hazardous chemicals within the plastic waste lifecycle to ensure recycled products are safe.
• Target 12.5: “By 2030, substantially reduce waste generation through prevention, reduction, recycling and reuse.” The article explicitly states that improving the safety of recycled plastics will “encourage higher recycling rates—ultimately reducing plastic waste in landfills.”
