Since its inception in 2018, the Doctoral Colloquium on Bioenergy and Biobased Products has developed into an international platform for early-career researchers covering the entire value chain of bioenergy and biobased products. Reflecting political, economic and scientific developments, the colloquium has continuously expanded its scope, most recently including biotechnology and bioeconomy research. Biomass, as the only renewable carbon source, plays a key role in sustainable energy carriers, materials and products. As a limited resource, its efficient use requires innovative concepts such as cascading use and system integration. The colloquium promotes scientific exchange and networking among doctoral researchers presenting their latest work.

The 9^th Doctoral Colloquium BIOENERGY and BIOBASED PRODUCTS will take place on 23-24 September 2026 in Leipzig and is organised under the scientific coordination of Prof Dr Michal Nelles and Dr Elena Angelova (DBFZ). Contributions for oral and poster presentations are curated by the Programme Committee and supported by a Scientific Advisory Board comprising 50 scientists from 39 institutions in Germany, Austria, Switzerland, Italy and Norway.

The Doctoral Colloquium BIOENERGY and BIOBASED PRODUCTS offers you as a young student pursuing your PhD in this field an opportunity to present your work and enter into a professional discussion and exchange. You are welcome at all stages of your dissertation and work. You have the chance to present your scientific approach, methods and results in form of an oral presentation or a poster. As a knowledge and decision-maker of tomorrow you can share knowledge, discuss research gaps and meet colleagues and experienced supervisors.

The “BIOENERGY and BIOBASED PRODUCTS” PhD colloquium covers all aspects of the biomass conversion chain, from feedstock through conversion technologies to the resulting products and services. It also addresses cross-cutting themes such as economic viability, environmental and social aspects, and encompasses work on system analysis and system integration. Research into biological principles and findings rounds off the topic. The event comprises the following five main research areas:

• SUSTAINABLE RESOURCE BASE
• BIOENERGY SYSTEM ANALYSIS (INCL. TECHNICAL INTEGRATION)
• THERMOCHEMICAL CONVERSION
• BIOCHEMICAL CONVERSION & BIOTECHNOLOGY
• BIOREFINERIES, BIOECONOMY & BIOFUELS
• SOCIAL SCIENCE PERSPECTIVES ON BIOENERGY AND BIOBASED PRODUCTS
