AbstractWe propose a quantization algebra of the Loday-Ronco Hopf algebra $$k[Y^\infty ]$$

, based on the Topological Recursion formula of Eynard and Orantin. We have shown in previous works that the Loday-Ronco Hopf algebra of planar binary trees is a space of solutions for the genus 0 version of Topological Recursion, and that an extension of the Loday Ronco Hopf algebra as to include some new graphs with loops is the correct setting to find a solution space for arbitrary genus. Here we show that this new algebra $$k[Y^\infty ]_h$$
