New legislation requiring diversion of food waste from landfills, along with the EPA's modified rules for Renewable Fuel Standard RIN qualification has presented both a challenge and an opportunity to Waste Water Treatment Plants. The mandated food waste diversion is driving localities to want to process food waste through anaerobic digestion, so the WWTP digester facilities are likely to be pressured to accept this feedstock. Coupling this with the revised EPA rules on D3 vs. D5 RIN designation for monetization of Renewable Natural Gas, WWTP can see a viable market to capture their biogas for considerable profit. This session will review the mandated diversion legislation and give a basic understanding of how the D3 vs. D5 RIN designation is calculated. The end result is that more biogas will be produced, which can be a profitable venture for the WWTP.
1. Review and describe the general trend in food waste diversion legislation
2. Describe how the diverted food waste legislation can impact WWTP digester operators
3. Describe the EPA's recent rulemaking concerning D3 vs. D5 RIN designation
4. Analyze how the Legislation and EPA Rulemaking affects the monetization of the processed Renewable Natural Gas
