Sustainable Technologies and Waste Valorisation Technologies

Dear Colleagues,

The rapid development of engineering, digitalisation, environmental biotechnologies, and intelligent systems is transforming the approaches used to manage modern agricultural systems. These advances are reshaping the technological foundations of sustainable industrial production. They also exert a significant influence on the environmental future of surrounding ecosystems.

This Special Issue focuses on emerging engineering and technology-driven solutions that integrate mechanical systems, automation, sensors, data-driven control, and bioprocessing to support efficient, sustainable, and circular agricultural and environmental systems. Topics of interest include advanced design, modelling, optimisation, materials processing, and performance evaluation of machines, working tools, and processing units; soil–machine interaction, terramechanics, and innovative approaches that couple soil processing and field engineering practices with technologies for the sustainable utilisation and valorisation of organic agricultural biomass; energy-efficient field operations; and ICT-based, robotic, and sensor-integrated platforms for soil, crop, livestock, and environmental monitoring.

Special attention is given to environmental technologies, biotechnologies, and the resource-efficient utilisation and valorisation of organic biomass, including by-products from crop production, livestock systems, and various branches of the food, forestry, textile, and other related industries. Relevant approaches include microbial consortia, solid-state fermentation, bio-oxidative processes, engineered bioreactors, and mechanochemical activation technologies such as vortex layer reactors. These systems enable the conversion of diverse biomass into bioenergy, humic substances, plant biostimulants, soil conditioners, feed additives, functional ingredients, and other value-added materials.

Research addressing postharvest technologies, storage stability, drying, preservation, materials transformation, and digital monitoring systems is also encouraged.

By combining engineering, biotechnology, ICT, materials processing, and environmental technology, this Special Issue aims to highlight next-generation solutions that improve soil health, enhance product quality and storage, reduce environmental impact, and promote circularity in agricultural and industrial systems.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Technologies is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
