The revised ASTM D6826-23 Standard Specification for Sprayed Slurries, Foams, and Indigenous Materials Used As Alternative Daily Cover for Municipal Solid Waste Landfills was published last week. Daily covers are an essential issue in managing odor release in landfills. This specification has been around for around 15 years, and this is the fifth revision of the text.
This specification defines procedures for determining the performance of certain landfill daily cover materials such as sprayed slurries, foams, and other materials generally described as an alternative daily cover (ADC) for municipal solid waste landfills. This standard specification does not apply to other types of landfills. Also, the text does not apply to geosynthetics used as ADC such as this one.
