Siloxane compounds, a major cause of engine damage, were almost completely removed (>99.8 % reduction). Volatile organic compounds decreased by ~89 % overall, with final concentrations of ~65 mg/m³. The prototype achieved its design flow of 1500 m³/h, supplying three CHP units with 2.8 MW of instantaneous electrical output. These findings confirm the system’s effectiveness, modularity, and applicability for broader deployment in EU waste-to-energy facilities. The technology enables cost-efficient energy recovery, compliance with EU environmental standards, and the potential future upgrading of LFG to biomethane for injection into natural gas grids or use as transport fuel. ]]> ARTICLE <![CDATA[Reduced Order Modelling for the Drone Flow Field: Autoencoder-Driven Nonlinear Compression Versus Pod]]> https://sciendo.com/article/10.2478/lpts-2025-0044 https://sciendo.com/article/10.2478/lpts-2025-0044 Sat, 06 Dec 2025 00:00:00 GMT ARTICLE <![CDATA[Comparison of Existing Methods for Purifying Gases from Ship Propulsion Engines]]> https://sciendo.com/article/10.2478/lpts-2025-0046 https://sciendo.com/article/10.2478/lpts-2025-0046 Sat, 06 Dec 2025 00:00:00 GMT ARTICLE
