Our research group is focused on the improvement and optimization of the composting process, both at laboratory scale and in full-scale industrial facilities. We specialize in process control and monitoring, developing innovative techniques to ensure a more efficient and sustainable composting process.
Control and Optimization of Composting
We have refined respirometry techniques with three main objectives:
✔ To monitor biological activity during the process.
✔ To assess the stability of the final compost.
✔ To determine the aerobic biodegradability of different organic wastes.
We have several dynamic respirometers available for research and for collaborations with companies and public administrations.
Environmental Impact of Composting
In addition to optimizing the process, we study its environmental impact and compare it with other biological waste treatment technologies.
Our research has enabled us to quantify greenhouse gas emissions based on experimental data collected from full-scale municipal solid waste treatment plants and landfills.
Current Research Lines
✔ Effect of biochar on composting: emissions and final product quality.
✔ Community and domestic composting.
✔ Biodegradability studies of wastes, products, and new materials.
✔ Combined composting and anaerobic digestion.
Other Research Lines
✔ Development of a controller based on Specific Oxygen Uptake Rate (SOUR).
✔ Image analysis techniques to estimate compost stability.
✔ Application of compost for soil bioremediation.
Working Scales
We conduct research at different scales, allowing us to study the process from fundamental science to industrial application:
🧪 Laboratory: controlled experiments for process optimization.
⚙️ Pilot plant: medium-scale trials to validate results.
🏭 Industrial plants: field studies under real-world conditions.
