The purpose of this creative component is to tell the journey of our research in the form of customer discovery from ISU I Corps Cohort spring 2018 to NSF National Innovation Corps spring 2019. The use of siloxanes is increasing everyday due to the physicochemical properties that are appropriate to be included in the formulations of a large variety of consumer products. The aim of this creative component is to provide the current state of knowledge concerning the presence of siloxanes in digester/landfill gas. ESF Environmental Solutions through participation in NSF National Innovation Corps conducted 110 customer discovery interviews across 15 U.S. states. The interview question to different customer archetype in WWTP’s and landfill enterprise consisted of asking them the problems faced during energy generation. Over the journey of interviews, it was learnt that siloxane nuisance affects the operation and economy of energy generation equipment in the form of increased maintenance and downtime. The renewed interest of industry in biogas pretreatment is primarily owing to the Renewable Identification Number (RIN) credits which is a currency of Renewable Fuel Standards (RFS). Payback period is the main concerning factor for industry prior to technology adoption. Biogas pretreatment for RNG is being attributed to economic benefits in the form of decreased engine maintenance costs and environmental credits in the form of RINs.
