30 percent more: these 3 shredding techniques increase biogas yield

Agricultural residues are becoming increasingly popular as cost-effective substrates for biogas plants - however, suitable processing is required. We introduce three promising comminution techniques. Scientific studies have shown that comminution technology positively influences gas yield. Optimal substrate processing can increase gas yield by up to 30 percent. At the same time, substrate costs decrease, as cost-effective residues can be used that were previously unusable or only partially usable without pretreatment. Hammer mill, roller mill, fiberizer The hammer mill operates at high speed with rotating impact bars and is suitable for dry to semi-dry substrates. The roller mill is also suitable for varying moisture levels and is more energy efficient than hammer mills. Fiberization systems have been specifically developed for biogas plants and not only shred the stalks, but also break down cell structures, accelerating decomposition. Our article "More Gas from Residues" explains which technique offers which advantages and what biogas yield you can expect.
