Synolys® - Double biomethane yield in the most carbon negative way

Synolys® Introduction

Synolys® is a game-changing technology that enables existing biomethane plants worldwide to reduce production costs, meet future regulations and maximize decarbonization effects. It combines biological and thermo-chemical processes to achieve double biomethane yield and negative carbon emission.

• Double biogas yield
• Convert non-conventional feedstocks to more biogas
• Convert negative value digestate to positive value biochar
• Eliminate microplastics and pharmaceutical residues
• Meet future regulations
• Maximize CO2 emission reduction
• Capture carbon in the biochar
