Politics of waste and waste management have been hotly contested topics in Lebanon since the trash crisis of 2015, with subsequent social movements connecting the mismanagement of waste to a mismanagement of the Lebanese state. Narratives on the circulation of waste abound in the city. One prominent example is the closed loop of solid waste circulating from coastal landfills to the sea, from the sea to the shore, and from the shore to the landfills. In this paper I look at the circulation of solid waste and sewage on the Beirut littoral. The paper is based on ethnographic fieldwork among Beirutis from different backgrounds on the topic of conflicts about littoral public space carried out in years 2015 and 2018. In Beirut, a city flanked north and south by allegedly mismanaged coastal landfills, the paper zooms in on a public beach in the city, flanked north and south by controversial sewage exhausts. In this paper I examine how flows of sewage and solid waste have been discussed, managed, engaged, and made sense of on the coastline of the Lebanese capital. I suggest that the spatial configuration of waste and the ways different people engage with it can be conceptualized as a convergence of spatial trajectories and changing temporalities. By this I mean that the actual flows of waste are tied to different expectations and understandings of futures and pasts. Connecting my ethnographic material to a collaborative radical cartographic endeavour that maps the circulation of waste and ensuing sites of resistance and spatial reconfigurations, I bring forth a novel understanding of how blockages and redirections, and connections and disconnections, in the circulation of waste unfold in a process of spatial and temporal reconfiguration. In conclusion, the paper argues that connecting ethnography and radical cartography can help us understand how perceived non-actualization of planned municipal waste-management projects in Beirut amount to a generalized sense of a deferral of future in relation to temporalities of waste. This perpetual postponement typical of the waste situation can be understood as a temporal alignment in understanding the Lebanese state - although such perceptions of eternal deferral are always subject to conflicting interpretations.
