Wetland development stimulates peat formation and peat layers serve as a natural barrier to infiltration. The peat layer absorbs almost all the precipitation, so almost no water infiltrates in the ground and through the waste material. This results in no or less leakage. Degradation of pollutants can take place in the peat layer through bacterial processes. <\/p>\n        <\/div>\n    <\/div>\n    <div class=\"block-before-after-column\">\n        <div class=\"block-before-after-title\">Traditional design<\/div>\n                    <div class=\"block-before-after-figure\">\n                <img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"179\" src=\"https:\/\/www.ecoshape.org\/app\/uploads\/sites\/2\/2020\/05\/vuilnisbelt-300x179.jpg\" class=\"attachment-medium size-medium\" alt=\"\" srcset=\"https:\/\/www.ecoshape.org\/app\/uploads\/sites\/2\/2020\/05\/vuilnisbelt-300x179.jpg 300w, https:\/\/www.ecoshape.org\/app\/uploads\/sites\/2\/2020\/05\/vuilnisbelt.jpg 639w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>            <\/div>\n                <div class=\"block-before-after-body\">\n            <p>In traditional designs, waste dumps are capped with metal or concrete sheets, bottom sealing and foil that has to be replaced over time.

The \u2018natural cap\u2019 concept combines natural peat and wetland development with waste encapsulation and degradation of pollutants in the peat layer.<\/p>\n\n\n\n<p>The Volgermeerpolder, North of Amsterdam, is an area that has been used as a toxic waste deposit site for years. The area used to be a peat excavation site where peat was exploited for fuel. In order to cope with toxic leakage from the 6 meter thick waste layer into the surrounding groundwater system, monitoring was initiated and a plan was developed to cover the mound. Monitoring of the water and soil quality showed that peat prevents leakage due to its impermeable character. This led to the innovative \u2018natural cap\u2019 design. The concept will be tested further in the coming years in order to verify and prove the full working of the concept. As such the Volgermeerpolder is one of the largest wetland development sites in the world.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Location: Volgermeerpolder, NetherlandsDate: 2001- presentInvolved parties: Advies Combinatie Volgermeerpolder (ACV, consisting of Witteveen+Bos and Tauw), Bouw Combinatie Volgermeerpolder (BCV, consisting of Boskalis, De.
