This conference is dedicated to the role of waste recycling in sustainable development and the identification of related environmental and economic benefits. The theme of the conference is "Biowaste – ecological value". The event was aimed at sharing knowledge, experience and ideas in the field of modern waste recycling technologies and safe reuse, reducing pollution and carbon dioxide emissions, as well as the role of biochar in improving soil health and food production. The conference provided a unique platform for establishing communications between representatives of science and business and finding global partners for future cooperation.

The event was attended by scientists from China, Russia, India, Norway, Australia, Brazil, Belgium, New Zealand, and Germany, who presented impressive results of their research. A delegation of the staff of the D.I. Ivanovsky Academy of Biology and Biotechnology of the Southern Federal University was invited to participate in the conference, which was held in two main areas: "Eco-recycling and safe reuse of waste" and "Biochar for soil health, food and feed".

Professor, Head of the Department of Soil Science and Land Resources Assessment, Doctor of Biological Sciences Tatyana Minkina presented a plenary report on the topic "Diagnostics of polluted soil and its remediation" ("Diagnostics of polluted soils and their remediation").

Professor, world-renowned leading scientist, head of the SFedU megagrant "Biorestavation of Polluted soil ecosystems" Ming Hung Wong made a plenary report on the topic: "Valorization of Organic Waste in Circular Cities, Emphasizing Food Waste".

Svetlana Sushkova, Chief Researcher, Head of the laboratory "Intelligent Agroecosystems", PhD, presented a report on "Antibiotic Resistance Genes in Soils of Technogenically Polluted Soil by Polyaromatic Hydrocarbons and Heavy Metals" ("Antibiotic resistance genes in soils technogenically contaminated with polyaromatic hydrocarbons and heavy metals").

Lead researcher, PhD Vishnu Rajpud presented a report on "Biochar and metal tolerant bacteria to alleviate the toxicity of nanoparticles on barely" ("Biochar and metal-resistant bacteria to reduce the toxicity of nanoparticles in conditions of minimal consumption").

First-year graduate student, junior researcher Priyadarshani Rajpud presented a report on "Insights into bio-waste biochar to remediate contaminated soil/water using emerging technology" ("Study of biological waste using biochar to restore contaminated soils/waters using modern technologies").

Tatiana Bauer, a leading researcher, PhD, presented a report on the topic "Design and mechanism of soil remediation biochar and nanocomposite materials for heavy metal contamination" ("Design and mechanism of soil restoration with biochar and nanocomposite materials to combat heavy metal pollution").

The reports of scientists present the results of research supported by the Ministry of Science and Higher Education of the Russian Federation, Agreement No. 075-15-2022-1122, No. 075-15-2022-1247 and the federal program "Priority 2030" (National Project "Science and Universities").

As part of the implementation of the international grant, together with the organizations of the BRICS countries, a working meeting was held with the project participants - Zhejiang University of Science and Technology (China) and Banaras Hindu University (India). During the meeting, issues of key carbonation technologies and rational disposal of urban food waste using big data and artificial intelligence were discussed. On the Russian side, this project is being implemented at the Southern Federal University under the leadership of Vishnu D. Rajput (Agreement No. 075-15-2022-1247).
