Agriculture Environmental Stewardship Act of 2021
This bill allows energy tax credits through 2023 for investments in (1) qualified biogas property, or (2) qualified manure resource recovery property. The bill also permits new clean renewable energy bonds to be used for such properties.
Qualified biogas property comprises a system that (1) uses anaerobic digesters or other specified processes to convert biomass into a gas which is at least 52% methane, and (2) captures the gas for use as a fuel. The term includes property that cleans and conditions the gas for use as a fuel.
Qualified manure resource recovery property comprises a system that uses specified processes to recover the nutrients nitrogen and phosphorus from a non-treated digestate or animal manure by reducing or separating at least 50% of the nutrients, excluding any reductions during the incineration, storage, composting, or field application of the non-treated digestate or animal manure. The term also includes certain processing equipment.
The Department of the Treasury must enter into an agreement with the National Renewable Energy Laboratory for a study of biogas and report to Congress on the study.
To amend the Internal Revenue Code of 1986 to make qualified biogas 
 property and qualified manure resource recovery property eligible for 
   the energy credit and to permit renewable energy bonds to finance 
           qualified biogas property, and for other purposes.

    Be it enacted by the Senate and House of Representatives of the 
United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Agriculture Environmental 
Stewardship Act of 2021''.

SEC. 2. FINDINGS.

    Congress finds the following:
            (1) Incentives and encouragement for the conservation and 
        appropriate handling of nutrients contained in organic matter 
        are necessary.
            (2) Biogas systems will save Federal, State, and local 
        taxpayers money by converting waste into useful products, such 
        as fuel, fertilizer, thermal heat, feedstock for hydrogen fuel 
        cells, and renewable chemicals.
            (3) Manure resource recovery systems will save Federal, 
        State, and local taxpayers money by recovering the nutrients 
        contained in organic matter from their source, rather than 
        recovering the nutrients after they have entered landfills or 
        waterways.

              MANURE RESOURCE RECOVERY PROPERTY.

agreement with the National Renewable Energy Laboratory to undertake a 
study of biogas that addresses the following:
            (1) The quality of biogas, including a comparison of biogas

        biogas which make biogas unsuitable for injection into existing 
        natural gas pipelines.
            (2) Methods for obtaining the highest energy content in 
        biogas, including the use of co-digestion and identifying the 
        optimal feed mixture.
            (3) Recommendations for the expansion of biogas production, 
        including an analysis of the extent to which increasing the 
        methane content of biogas would result in the greater use of 
        biogas and an analysis of how the expanded use of biogas could 
        help meet the growing energy needs of the United States.
            (4) Methods for productive use of nutrients recovered from 
        qualified manure resource recovery property that benefits the
