Wet vs Dry Anaerobic Digestion: Pros and Cons & Biogas Yield Compared

Wet vs. Dry Anaerobic Digestion: Pros, Cons & Biogas Yield Compared Are you deciding between wet anaerobic digestion and dry anaerobic digestion for your waste-to-energy project? In this video, we break down the technical differences, advantages, and limitations of both systems so you can choose the right process for your waste stream — whether you’re dealing with food waste, manure, sewage sludge, yard waste, OFMSW, or agricultural residues. 🔎 What You’ll Learn: Why wet AD (less than 15% solids) dominates home and farm-scale digesters How dry AD (20–40% solids) handles stackable municipal and agricultural waste Why wet systems usually deliver higher biogas yields per tonne The trade-off between water demand vs. footprint size When dry digesters make sense for contaminated or residual waste How UK & EU waste treatment trends influence AD technology choices Wet digesters are typically continuous stirred tank reactors (CSTRs) — easy to pump, mix, and operate long-term. However, they require significant water input and produce large volumes of liquid digestate. Dry digesters operate in batch tunnels or plug-flow systems, using percolation to extract biogas from stackable material. They use less water and tolerate contamination better — but handling thick feedstock requires specialist loading systems. In short: ✔ Wet AD = higher biogas yield, continuous operation ✔ Dry AD = lower water use, smaller footprint ✔ The right choice depends entirely on your feedstock and objectives Both technologies play a critical role in delivering renewable biogas and biomethane for a net-zero future. 👉 For deeper technical guidance on dry anaerobic digestion systems, performance data, and design considerations, visit: https://anaerobic-digestion.com/dry-a... #anaerobicdigestion #biogas
