Agricultural and Biosystems Engineering for Implementing the Circular Economy Concept in Agriculture

Dear Colleagues,

Agricultural and Biosystems Engineering provides agricultural actors with the knowledge and skills required to use advanced technologies that can transform waste into new resources, thus contributing to the implementation of the Circular Economy concept in agriculture. Indeed, by managing organic (biomass) and non-organic (mostly, agro-plastics) waste, farmers can increase their economic returns while reducing the environmental footprint of agriculture. This Special Issue reports the results of scientific research and training activities carried out by Agricultural Engineers—mostly those implemented within the TANGO-Circular Project, in which farmers and agricultural stakeholders were trained on the appropriate use, post-consumer collection, and recycling of agricultural co-products, by-products, residuals, and waste. Their upskilling allowed them to play a proactive role in the valorization of agricultural waste, which was consolidated thanks to the participation of other interested actors involved in the Quadruple-Helix, including public institutions, private industries, universities/research centers, and civil society/non-profit organizations. During the Project Final Conference, held in Matera, Italy, on 25–27 June 2025, several European universities specializing in Agricultural and Biosystems Engineering presented data on the latest technologies and systems for valorizing agricultural waste, discussing on how to implement and harmonize them, thus shading light on cutting-edge technological solutions and creating innovative opportunities in agricultural waste valorization.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. AgriEngineering is an international peer-reviewed open access monthly journal published by MDPI.
