Highest waste concentration for a dump site

According to the D-Waste Association, the dumpsite with the highest waste concentration is Eneka in Port Harcourt, Nigeria; it has a waste concentration of 1,680,000–2,400,000 tonnes/ha. This would be enough to cover the football pitch in Wembley Stadium with up to 3,333,000 tonnes of waste – about half of the weight of the Great Pyramid of Giza. The site covers an area of 5 ha (0.05 km²) and contains 8.4–12 million tonnes of waste.
