Landfill restoration

Once a landfill is capped, restoring the land with vegetation has been considered as an appealing approach since it reconnects the degraded land with the surrounding natural environment. == Regional studies ==

Hong Kong A 10-year study done at the SENT landfill in Tai Chik Sha in Tseung Kwan O, Hong Kong, shows that plant and tree species could survive following the restoration of a landfill. The researchers of the study note that the Puglia region is "the most drought-ridden of Italy and a dry Mediterranean macroclimate characterizes the area", with an average annual precipitation of 500–700 mm and an annual average temperature of 16.8 °C. On these sites, there was a total of 63 species of insect pollinated plants found, with 19 found exclusively on the restored sites compared to the reference sites. - ultimately proving that landfill restoration provides an excellent resource in improving populations of pollinator insects. == Areas of further research ==

Canada Parc Frédéric-Back, located in Montréal, is a former limestone quarry which was also used as a landfill site that recently became transformed into a public park, with its completion expected in 2026. This site contains approximately 40 million tons of landfill waste since its initiation in 1986 until it was closed in 2009. The Master Plan of the park is expected to include a meadow, a forest, terraces, and a Crown area that hosts the cultural, sports and industrial-commercial-poles, in addition to the 17 entrances to the park. The objectives of the Master Plan include increasing knowledge of environmental rehabilitation, enhancing the quality of life of the surrounding residents, and protecting and improving biodiversity in Montréal—the latter which has yet to be evaluated since the construction of the park is still fairly new. == References ==
