A virtuous multi-step biorefinery platform to convert urban biowaste into valuable molecules, not disregarding renewable energy and digestate production. The strategy is based on the integration of a thermal pretreatment capable of significantly increasing the fraction of fermentable organic carbon, in order to furthermore change the status of the feedstock to become more suitable for production of a) high-value bio-based molecules, b) biomethane and c) hygienized digestate to be recycled as biofertilizer.

The prototype uses soil moisture sensors which, through a measurement of dielectric permittivity, estimate the soil moisture based on which irrigation is started through relay-controlled solenoid valve. The system was developed using Open Source technologies. Specifically, for the hardware components, a small sized board computer Raspberry PI 3B + was used together with a 4G LTE Wi-Fi router and a Modbus rs485 / USB converter.
