Technical Data of the Equipment Used

Factors	Tunnel Composting
Tunnel	The tunnel will be of concrete or other non‐corrosive construction as an enclosed vessel
Water content at start‐up in the feedstock mixture	50–65%
Watering	As required during the process. During the post‐hygienisation phase, only clean water can be added
Ventilation	Forced aeration is provided by an aeration floor beneath the mass in the tunnel. The warm air is recirculated
Turning Equipment	Front end loader in order to load and unload the tunnels. Automatic filling system
Temperature during hygienisation	Standard 1: 55°C; Standard 2: 60°C
Temperature Monitoring	Temperature should be monitored to ensure that it is representative of the temperatures within the composting mass
