    Technological Innovations and Circular Economy in the Valorization of Agri-Food By-Products: Advances, Challenges and Perspectives
    (Multidisciplinary Digital Publishing Institute. Food, 2025-05-30) Sucari León, Reynaldo; Ligarda Samanez, Carlos A.; Huamán Carrión, Mary L.; Calsina Ponce, Wilber Cesar; Germán De la Cruz; Calderón Huamaní, Dante Fermín; Cabel Moscoso, Domingo J.; Garcia Espinoza, Antonina J.; Aroquipa Durán, Yolanda; Muñoz Saenz, Jenny C.; Muñoz Melgarejo, Mauricio; Jilaja Carita, Enoc E.
    The valorization of agri-food by-products is a critical pathway toward building sustainable food systems, reducing waste, and advancing the circular economy. This review aims to identify recent advances, key challenges, and future perspectives in this field. We conducted a critical and systematic synthesis of 159 peer-reviewed studies (2019–2025) selected based on quality and thematic relevance from leading international databases. The analysis focuses on emerging technologies such as ultrasound-assisted extraction, microencapsulation, spray drying, lyophilization, deep eutectic solvents, and colloidal systems, emphasizing their efficiency in recovering bioactive compounds from agro-industrial by-products. Significant challenges include industrial scalability, economic feasibility, regulatory compliance, and consumer acceptance. This paper also discusses current applications in functional foods and nutraceuticals, outlining promising directions for the sector. Although challenges remain, the findings offer valuable insights for researchers, industry, and policymakers aiming to foster sustainable innovation and implement strategies aligned with circular economy principles.

    Technological Innovations in Sustainable Civil Engineering: Advanced Materials, Resilient Design, and Digital Tools
    (Multidisciplinary Digital Publishing Institute. Sustainability, 2025-09-29) Sucari León, Reynaldo; Huamán Carrión, Mary L.; Cabel Moscoso, Domingo J.; Muñoz Sáenz, Doris Marlene; Martinez Hernandez, Jaime Antonio; Garcia Espinoza, Antonina J.; Calderón Huamaní, Dante Fermín; Carrasco Badajoz, Carlos; Darwin Pino Cordero; Aroquipa Durán, Yolanda
    Civil engineering today faces the challenge of responding to climate change, rapid urbanization, and the need to reduce environmental impacts. These factors drive the search for more sustainable approaches and the adoption of digital technologies. This article addresses three principal dimensions: advanced low-impact materials, resilient structural designs, and digital tools applied throughout the infrastructure life cycle. To this end, a systematic search was conducted considering studies published between 2020 and 2025, including both experimental and review works. The results show that materials such as geopolymers, biopolymers, natural fibers, and nanocomposites can significantly reduce the carbon footprint; however, they still face regulatory, cost, and adoption barriers. Likewise, modular, adaptable, and performance-based design proposals enhance infrastructure resilience against extreme climate events. Finally, digital tools such as Building Information Modeling, digital twins, artificial intelligence, the Internet of Things, and 3D printing provide improvements in planning, construction, and maintenance, though with limitations related to interoperability, investment, and training. In conclusion, the integration of materials, design, and digitalization presents a promising pathway toward safer, more resilient, and sustainable infrastructure, aligning with the Sustainable Development Goals and the concept of smart cities.
