Our bioreactor project sets new standards in the circular economy by efficiently converting expired food into high-quality compost. This serves as a natural fertilizer that improves soil health and replaces synthetic alternatives. Using a static composting process, our bioreactor promotes a high level of microbiological diversity – without time-consuming and labour-intensive turning or high energy consumption.
Sustainability and impact
With our approach, we make a double contribution to the environment: reducing food waste contributes to CO₂ savings, while the use of compost as a carbon storage actively combats climate change. Our aim is to spread this technology in Germany and make agriculture more environmentally friendly.
Technological innovations
Our system is based on the Johnson-Su principle and combines simple operation with state-of-the-art technology:
- Efficient irrigation: Thanks to moisture sensors and optimized spray nozzles, water is used in a targeted and resource-saving manner.
- Temperature control: An intelligent zone system ensures even heat distribution, maximizing compost quality.
- Energy-efficient control: Monitoring and automation is carried out by modern microcontrollers such as Raspberry Pi, which minimize energy consumption.
- Real-time monitoring: Advanced sensor technology continuously measures the nitrogen and carbon content, the pH value and the temperature of the compost. This data enables dynamic adjustment of the composting processes to ensure maximum efficiency.
Future vision and scaling
The bioreactor was developed for small and medium-sized applications, but we are working on scaling it up to industrial standards. Our vision is a Germany-wide network of bioreactors that convert food waste into valuable compost. With innovative technologies and a dedicated team, we want to shape the sustainable agriculture of the future.
