Customer benefits
Prevents ammonium spikes
By separating and treating urine on-site, the system prevents sudden surges of ammonium-rich wastewater from entering municipal treatment plants. This helps avoid overloads, ensures stable plant operation, and protects local water bodies from harmful discharges.
Produces sustainable fertilizers
Nutrients captured from urine are transformed into high-quality fertilizers with a 60% lower CO₂ footprint compared to conventional synthetic fertilizers. This reduces dependence on fossil-based fertilizer production while providing a tangible, eco-friendly product for agriculture.
Enables circular nutrient recovery
Instead of losing valuable nitrogen and phosphorus through the sewer system, these resources are recovered and reintroduced into the food chain. By closing the loop, festivals like Decibel Outdoor contribute to a more resilient and sustainable food production system.
Showcases innovative water management
Large-scale festivals are high-visibility events. By implementing circular water and nutrient solutions, Decibel Outdoor not only reduces its own environmental footprint but also demonstrates how innovation can transform water management — inspiring visitors, policymakers, and other organizers to rethink resource use.
