A unique part of Amsterdam is currently being developed on Zeeburgereiland: the Sluisbuurt. A district with a very high population density. There will be no fewer than 5,500 apartments, most of them high-rise buildings. That means 375 homes per hectare. So a relatively large amount of waste will be generated. That is why the municipality has started looking for a new way of collecting waste, a system in which transport does not take place by road but underground.
It is therefore called: Underground Waste Transport System (OAT). Residents can dispose of their garbage bags within their building in a number of inlets. There are always four disposal openings next to each other: one for residual waste, one for GFE (Vegetables, Fruit and Food Waste), one for OPK (Waste Paper and Cardboard) and one for PMD (Plastics, Metals and Drinking Cartons). These inlets, equipped with an internal buffer, are connected to a pipe system in the ground.
They are suctioned in turn, if necessary even several times a day. The pipe system ends at a terminal, where the waste is collected one by one to be transported to the incinerators or other terminal stations.
