Multriwell is the new and durable solution for landfill gas extraction. This innovative technology enables landfill operators to extract considerably more gas compared to when traditional gas wells are used. The system consists of three components: short distance flexible vertical gas wells that are installed in very small grids, horizontal gas collection wells and a Trisoplast capping construction. Waste perforation within very small grids causes an enhanced bio-reaction, resulting in faster achievement of landfill inertia and settlement. Moreover leachate is spread more evenly through the waste, generating a higher biogas produce.
