Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit a manuscript to this Special Issue on Bio-Based Products and Co-product Applications. This issue is dedicated to exploring the dynamic field of utilizing food wastes and by-products to create sustainable solutions. Our focus is on the latest advancements in extracting, isolating, characterizing, and analyzing valuable compounds from these sources, contributing to a greener future. Highlighting the Special Issue's core objectives, we delve into the innovative utilization of bio-based products and co-products across diverse domains, and explore new breakthroughs in the extraction and isolation of bioactive compounds, unveiling their potential for varied applications. From cosmetics to food, pharmaceuticals to environmental initiatives, this issue showcases the transformative power of repurposing waste materials.

By spotlighting pioneering research in this field, we aim to foster environmentally conscious practices, minimize waste, and promote circular economy principles. Join us in exploring the limitless possibilities of bio-based products and co-products, as we endeavor to revolutionize industries while embracing sustainability. This Special Issue serves as a platform to share pioneering ideas, driving positive change on both ecological and industrial fronts. In this context, original research papers and comprehensive review articles delving into any of these diverse domains are encouraged for submission.

This study addresses the need for a comprehensive understanding of digestate and biochar in mitigating climate change and improving soil health, crucial for sustainable agriculture within the circular bioeconomy framework. Through a mesocosm experiment, soil was amended with digestates from pilot-scale reactors and two concentrations of biochar produced by pyrolysis of digested sewage sludge and waste wood. The Germination Index (GI) assay assessed phytotoxicity on Lactuca sativa and Triticum aestivum seeds. Greenhouse gas emissions (CO2, CH4, N2O) measurements, soil characteristics analyses, and the study of microbial community structure enriched the study’s depth. The GI assay revealed diverse responses among by-products, dilution rates, and plant types, highlighting the potential phyto-stimulatory effects of digestate and biochar water-extracts. While digestate proved to be effective as fertilizer, concerns arose regarding microbial contamination. Biochar application reduced Clostridiaceae presence in soil but unexpectedly increased N2O emissions at higher concentrations, emphasizing the need for further research on biochar’s role in mitigating microbial impacts. CO2 emissions increased with digestate application but decreased with a 10% biochar concentration, aligning with control levels. CH4 uptake decreased with digestate and high biochar concentrations. The study underscores the importance of tailored approaches considering biochar composition and dosage to optimize soil greenhouse gas fluxes and microbial communities. Full article

Powdered foods are easy to store and transport, with a longer shelf life that minimizes potential waste, contributing to sustainable development. Each food category has a unique composition, responsible for its chemical and physical attributes, which directly influences the stability of powdered products. The drying method used is essential to obtain the desired characteristics of the powdered food, and the choice of each technology can provide unique morphological properties regarding size, shape, and density, among other factors. Furthermore, rehydration properties must also be investigated, as they play a fundamental role in the reconstitution of powdered foods, influencing the dispersion and dissolution of the powder in liquids. Therefore, this review provides a comprehensive overview of the powdered food manufacturing process and its advantages. Special attention is given to the desirable properties of food powders, challenges related to stability, powdered food reconstitution properties, and case studies regarding many powdered foods.
