Sircle provides a real time data for solid waste bins fill-levels and local traffic conditions. Sircle quantify and monitor solid waste bin fill levels ultrasonically to alert solid waste collection trucks when the bin needs to be emptied. Optimised collection routes are then identified, which diverts solid waste collection fleets away from traffic jams and smaller roads, then identifies the best routes to take. This improves the efficiency of the collection of municipal solid waste (MSW) and reduces operational costs.
