Food waste valorisation for a circular bioeconomy: integrating biochemical, thermochemical, and digital technologies with sustainability metrics

Food loss and waste (FLW) has emerged as a major global challenge, contributing to resource depletion, greenhouse gas emissions, and food insecurity throughout the agri-food supply chain. Transforming FLW into value-added products offers significant opportunities to advance the circular bioeconomy while improving resource efficiency and environmental sustainability. This review critically synthesizes recent advances in food waste valorisation by integrating biochemical, thermochemical, and integrated biorefinery technologies with sustainability assessment and digital innovations. A PRISMA-guided literature review was conducted using major scientific databases to evaluate food waste valorisation pathways, including anaerobic digestion, fermentation, enzymatic hydrolysis, hydrothermal carbonization, pyrolysis, gasification, and integrated biorefineries. The selected studies were comparatively analysed with respect to feedstock suitability, technology readiness, resource recovery potential, environmental performance, life cycle assessment (LCA), and circular bioeconomy principles. The synthesis indicates that integrated biorefinery systems provide superior resource recovery and product diversification compared with single-technology approaches by simultaneously producing biofuels, biochemicals, biofertilizers, biopolymers, enzymes, and other value-added products. No single technology is universally optimal; rather, technology selection depends on feedstock characteristics, process efficiency, infrastructure availability, economic feasibility, and regional socio-economic conditions. The review further identifies artificial intelligence, the Internet of Things (IoT), and smart monitoring systems as emerging tools for improving waste segregation, process optimization, and traceability. Key barriers to large-scale implementation include inconsistent feedstock quality, limited infrastructure, fragmented regulatory frameworks, market constraints, and inadequate sustainability assessment. This review provides an integrated analytical framework that combines advanced valorisation technologies, sustainability assessment, digital innovations, and circular bioeconomy principles. It identifies key technological and governance gaps, compares major valorisation pathways, and outlines strategic priorities for developing resilient, resource-efficient, and climate-responsive food waste management systems that support sustainable development. Analyses integrated biorefinery approaches for food waste valorisation across agri-food value chains. Assesses thermochemical and biochemical routes for converting food waste into value-added products. Discusses environmental and economic trade-offs in food waste valorisation using LCA-based perspectives. Explores non-conventional green technologies and niche bioproducts from food waste. Identifies barriers and opportunities for scaling sustainable food waste management.

Plastic waste management and the emergence of microplastics as an integrated challenge involving sources exposure pathways health implications and circular solutions

Plastic pollution has emerged as a pervasive global environmental and public health challenge, affecting terrestrial and aquatic ecosystems across all spatial scales. Macro-, micro-, and nanoplastics enter food webs through ingestion, inhalation, and trophic transfer, posing distinct yet interconnected toxicological and physiological risks to wildlife and livestock, while potential implications for human health are still being actively investigated. Macro plastics primarily cause physical injuries, gastrointestinal obstruction, starvation, and mortality in marine and terrestrial animals, while microplastics act as vectors for chemical additives and pathogens, inducing oxidative stress, inflammation, and microbiome disruption. Nanoplastics, due to their small size and high surface reactivity, exhibit enhanced bioavailability, enabling cellular uptake and translocation across biological barriers in experimental systems, with studies indicating potential genotoxic and endocrine-disrupting effects. However, evidence regarding long-term human health outcomes remains limited and is still emerging. This review synthesizes current evidence on exposure pathways, biological impacts, and ecosystem-level consequences of plastic pollution, highlighting critical knowledge gaps related to chronic toxicity, mixture effects, and long-term health outcomes. This review uniquely integrates waste management system failures, toxicological mechanisms, and circular economy interventions to provide a systems-level synthesis of plastic pollution pathways from production to health outcomes. We further examine mitigation strategies through a circular economy lens, emphasizing source reduction, product redesign, extended producer responsibility, improved waste management, and policy coherence across scales. Integrating technological innovation with governance, behavioral change, and stakeholder collaboration is essential to curb plastic leakage and prevent secondary micro- and nano plastic formation. Overall, addressing plastic pollution requires systemic, science-based interventions that link environmental protection with human health objectives. Such integrated approaches directly support the achievement of Sustainable Development Goals 3 (Good Health and Well-Being), 12 (Responsible Consumption and Production), 14 (Life Below Water), and 15 (Life on Land), reinforcing the urgency for coordinated global action.
