Tarpomatic is a daily cover that is placed on the tip face of an active cell of a landfill. This solution was presented during the 2019 International Solid Waste Association world congress, although thiscompany has already a trajectory of 25 years delivering tarpaulin covers around the world.
Managing odour impact of landfills is usually challenging. There are not many useful methods to abate odour from these large surfaces with plenty of fugitive odours coming from everywhere. One of the main sources of odour emission is the working front of the landfill. A daily cover of the tip face of a landfill is a must, when there are odour complaints from the communities nearby. Tarpomatic offers a quick and cheap way to cover this surface.
CALPUFF Version 7.3.1 has been released. This version incorporates an agricultural spraying source type. In addition, several bugs were identified and fixed in Version 7.2.1 including issues with the use of multiple sub-hourly variable emissions files and processing missing layers in AERMET generated .PFL files. This model is out of the list of recommended models of the US EPA but it is the most appropriate under low wind/calm conditions that influence odour impact and with complex terrains.
