SyreN Changes

The SyreN System uses acidification technology to improve the nutrient value of the slurry and make it profitable for the farmer.

The stabilisation of slurry (acidification) to increase the nutrient values in slurry and eliminate the emissions - ammonia, methane, nitrous oxide - can be neutralized with the SyreN System. To become a profitable technology for agriculture and to compete with mineral fertilisers, it needs a new income source. This is offered by the SyreN Changes monitoring system through adoption of the carbon credit system and the issue of CO2 quotas that can be marketed and create a new income. A battery /solar powered wireless monitoring system for slurry storage tanks creates the needed documentation of pH value. An innovative business model makes this attractive for the farmer as it involves no labour and no investment. The use of the SyreN business model makes slurry application sustainable and legislative compliant.
