废弃口罩用于可持续绿色混凝土

Waste masks for sustainable green concrete

在COVID-19大流行期间,观察到一次性口罩的生产和使用突然激增,用过的口罩正在形成一种新的废物流,这是一种新形式的不可生物降解的塑料废物,需要数百年才能分解。因此,迫切需要以环保的方式对此类废物进行资源化回收利用。整理了许多有关废弃口罩纤维在建筑材料方面的使用案例,并且得到证实,废弃口罩可以可持续地用于帮助建造绿色建筑,通过重新利用废弃口罩生产具有更好强度和更高耐久性的改良混凝土,实现了循环经济和可持续性,以及有效的废物管理。

During the COVID-19 pandemic,a sudden surge in the production and use of disposable masks has been observed,and used masks are creating a new waste stream,a new form of non-biodegradable plastic waste that takes hundreds of years to break down.Therefore,it is urgent to recycle this kind of waste in an environmentally friendly way.To this end,many examples of the use of waste mask fibres in construction materials have been compiled and it has been demonstrated that waste masks can be sustainably used to help build green buildings.Circular economy and sustainability,as well as effective waste management,are achieved by reusing discarded masks to produce improved concrete with better strength and durability.
