The Spanish Association of Water Supply and Sanitation (AEAS) agreed in 2018 to create a specific sub-group dedicated to odour management (SGO) within the Operations, Technology and Energy group of AEAS. Five years later, AEAS has elevated the status of the SGO to become a fully-fledged group. This is fantastic news for any odour manager interested in this sector.

   On Wednesday 11th May, the plenary meeting of the Commission V of the Spanish Association of Water Supply and Sanitation (AEAS) took place. At this meeting, it was decided that the Odour Management Subgroup would become the Odour Management Group (GGO), no longer under the umbrella of the Operations, Technology and Energy Group. This decision adds more weight and responsibility to the group of people working on various odour management projects.

   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.
