Yes, almost all of what is used during the construction phase can be recovered or recycled when it reaches the end of its useful life. In addition, a concerted effort is underway to advance solutions that further increase the amount of materials that can be recovered, including those used on construction sites and those that are already almost entirely recycled. The most important challenge in the circularity of hydropower processes is in the dismantling phase. As recommended by the European Commission, it is important to completely remove inefficient or obsolete plants from the river system , restoring the river in question to a good ecological condition. Today, the dismantling phase is taken into consideration even during the design stage, including the effects of associated infrastructure such as access roads, pipelines or power lines. Finally, on the topic of recycling and reuse, it should be noted that there is no waste or consumption of water during the power generation phase, as the water flows without being contaminated or made unusable.
