Advancements in Chemical Assessment for Sustainable Innovation

The Importance of Safe and Sustainable Chemical Design

In recent years, the significance of safe and sustainable chemical design has garnered increasing attention. The global landscape is changing, as pollutants and hazardous materials pose significant threats to both human health and the environment. The Safe and Sustainable by Design (SSbD) framework has emerged as a critical approach to address these concerns. This framework emphasizes the need to consider safety and sustainability at every stage of the chemical life cycle, from initial design to production, use, and eventual disposal (Serra et al., 2025).

The Chemicals Strategy for Sustainability (CSS), a cornerstone of the European Green Deal, aims to phase out harmful substances while promoting safer alternatives. However, the existing methodologies for evaluating chemicals often lack integration and comprehensiveness. Traditional assessments typically evaluate health, environmental, and economic impacts independently, resulting in fragmented decision-making processes that do not capture the complexities of chemical interactions within ecosystems (Serra et al., 2025).

To achieve a truly sustainable future, it is essential to implement an integrated approach that encompasses the various dimensions of chemical assessment. The INSIGHT project aims to bridge these gaps by developing a novel computational framework for chemical and material impact assessment that integrates multiple domains of knowledge, thus offering a holistic perspective on the ramifications of chemical use.

Integrated Framework for Chemical and Material Impact Assessment

The INSIGHT project introduces an integrated framework designed to evaluate chemical and material impacts across environmental, health, social, and economic dimensions (Serra et al., 2025). This framework utilizes the Impact Outcome Pathway (IOP) approach, which extends the Adverse Outcome Pathway (AOP) concept by linking mechanistic insights to broader sustainability considerations.

The Impact Outcome Pathway (IOP) Concept

The IOP framework establishes causal links between chemical properties and their environmental, health, and socio-economic consequences (Serra et al., 2025). By integrating multi-source datasets—including toxicological profiles, life cycle inventories, and exposure models—INSIGHT promotes a structured knowledge graph that adheres to the FAIR principles (Findable, Accessible, Interoperable, Reusable). This integration ensures that data can be utilized effectively across various research domains, facilitating comprehensive impact assessments.

The IOP approach allows for a unified assessment framework that transcends traditional methodologies by enabling decision-makers to evaluate trade-offs and synergies between different impact dimensions. This is particularly relevant as industries face stricter regulatory standards and public demand for safer, more sustainable chemical products (Serra et al., 2025).

Utilizing Artificial Intelligence in Chemical Evaluations

Artificial Intelligence (AI) is revolutionizing the field of chemical evaluations by enhancing the predictability and interpretability of chemical and material impacts (Serra et al., 2025). The INSIGHT project employs AI-driven knowledge extraction techniques to analyze large datasets, enabling researchers to identify patterns and make informed predictions about the safety and sustainability of chemicals.

AI-Driven Knowledge Extraction

AI-driven models can analyze complex datasets and derive insights that may not be readily apparent through traditional analytical methods. For example, by utilizing machine learning algorithms, researchers can enhance their understanding of the interactions between chemical properties and biological responses, thereby improving the accuracy of risk assessments (Serra et al., 2025).

Moreover, AI facilitates the development of interactive decision-support tools that enable stakeholders to navigate complex datasets and modeling outputs with ease. This democratization of access to sophisticated analytical tools empowers industry stakeholders, policymakers, and regulatory bodies to make informed decisions regarding chemical safety and sustainability.

Case Studies Showcasing Innovations in Chemical Safety

The INSIGHT project has initiated several case studies to demonstrate the applicability of its integrated assessment framework. These case studies focus on diverse chemical classes, including per- and polyfluoroalkyl substances (PFAS), graphene-based materials, synthetic amorphous silica (SAS), and antimicrobial coatings (Serra et al., 2025).

1. Per- and Polyfluoroalkyl Substances (PFAS)

PFAS have been widely utilized in various industrial applications due to their unique chemical properties. However, their environmental persistence and potential health risks have raised significant regulatory concerns (Serra et al., 2025). The INSIGHT framework aims to develop computational models to identify safer alternatives to PFAS in lubricant formulations, integrating predictive toxicology models and environmental fate modeling to assess the feasibility of replacements.

2. Graphene-Based Materials (GBMs)

Graphene-based materials have garnered considerable interest in materials science due to their exceptional properties. However, challenges remain regarding their scalability and potential toxicity. The INSIGHT project evaluates the impact of GBMs on composite material durability and recyclability, leveraging computational models to assess their environmental fate and exposure scenarios (Serra et al., 2025).

3. Synthetic Amorphous Silica (SAS)

The transition from conventional SAS to bio-based alternatives provides an opportunity to enhance sustainability in tire manufacturing. The INSIGHT framework employs life-cycle assessments to compare the environmental impacts of bio-based SAS against conventional options, thus informing regulatory compliance pathways (Serra et al., 2025).

4. Antimicrobial Coatings

Antimicrobial coatings are increasingly utilized in healthcare and consumer products to prevent microbial contamination. The INSIGHT project evaluates the performance of nano-enabled antimicrobial coatings compared to conventional disinfectants, using computational modeling to predict their long-term environmental impacts and assess regulatory compliance (Serra et al., 2025).

Future Directions for Chemical Risk Assessment and Sustainability

The future of chemical risk assessment lies in the continued integration of mechanistic insights, AI technologies, and comprehensive data management strategies. The INSIGHT project emphasizes the importance of aligning its framework with regulatory standards to ensure stakeholder acceptance and facilitate the practical implementation of its findings.

Advancing Regulatory Integration

The INSIGHT project has established collaborative links with key initiatives such as the Partnership for the Assessment of Risks from Chemicals (PARC) and expert groups within the Organisation for Economic Co-operation and Development (OECD) (Serra et al., 2025). These collaborations focus on refining the SSbD framework to enhance regulatory acceptance and ensure that the outputs align with industry standards.

Promoting Interdisciplinary Collaboration

To address the complexities of chemical safety and sustainability, interdisciplinary collaboration between academia, industry, and regulatory bodies is essential. The INSIGHT project encourages joint efforts to develop innovative assessment methodologies and decision-support tools that can advance the field of chemical assessment.
