The Construction Industry Rises to the Plastic Challenge

As the world wakes up to the environmental challenges posed by massive plastic consumption, the construction industry is reducing its reliance on single-use plastics and increasing its use of recycled plastics.

塑料物品可以占地一千千年来降低垃圾填埋场,但在近期,材料的声誉在更快的夹子上退化。提高对环境影响的认识促使企业和个人与塑料重新评估。188bet滚球投注

作为一次性塑料的主要消费者,建筑行业可以通过使用较少,相反,重用和回收更多,帮助彻底减少浪费。

The most common plastics used in construction are polyvinyl chloride (PVC), high-density polyethylene and expanded polystyrene. Plastic is used for various applications such as seals, windows and doors, pipes, cables, floor coverings and insulation.

该行业传统上也使用塑料薄膜进行包装。在存在设施和管理回收系统的情况下,包装可以捆绑并在能量 - 从废物植物中焚烧。

Plastics Are Not All Equal

并非所有塑料都不糟糕,并且在行业内的消费看起来延长,塑料管道,例如,已经考虑了大多数新的管道安装。

“与民众的信仰相反,承认建筑塑料往往是一个积极的事情,这是一个很好的事情,”可持续发展咨询资源期货的主要顾问艾伦桑迪兰斯说。“许多人都是高度耐用的,持久持久和永久安装,所以他们不太可能成为海洋垃圾,”他说。

此外,塑料具有成本效益,强大但光线,易于形成且易于维护。

“施工的主要挑战是在其生命结束时分离,重用和回收塑料废物的努力,”Sandilands国家。“福利并不总是经济上重要意义 - 这是企业社会责任和对最佳可持续实践的承诺 - 所以它可能是一个艰难的出售。”

He adds: “From our experience, there has not been a huge drive to tackle single-use plastics in the construction industry in the same way that we’re seeing elsewhere, because it’s insignificant in terms of tonnage compared with other waste streams and doesn’t greatly affect contractors’ bottom lines.”

保护企业环境声誉的必要性正在推出建筑业内的风险议程,相信摩尔188bet滚球投注斯能源和权力实践董事总经理的唐娜托马斯。“在建设项目对环境造成损害的情况下,已经有了高调的案例,或者随着尚未开始的项目,公众对损害的潜力有担忧;188bet滚球投注我们知道这些情况可能会对所涉及的公司的声誉产生负面影响,“她说。

How Are Companies Taking Action?

Some companies are trying to make a difference, recognizing the reputational benefit of doing so.

In 2019, German developer and builder Diringer & Scheidel Group used recycled plastic in the construction of a 13-story residential tower to save 1,613 tons of concrete and 136 tons in carbon dioxide emissions. The builder used a patented void-former system by Heinze Cobiax Deutschland that uses recycled plastic; essentially, steel-reinforced plastic air bubbles were used to replace up to 35% of reinforced concrete normally required in slabs.

In the U.K., Mace is one of several firms to set targets to reduce its use of plastics, through its “Time to Act” campaign.

与客户和公司的供应链一起,MACE采取措施减少一次性塑料,包括采用可重复使用的鞋盖,闭环系统,用于防护塑料薄片,以及用于混凝土冲洗的可重复使用的跳过衬垫的试验。

Mace has also worked with its mechanical and electrical supply chain to change how it uses plastic in goods — with one supplier ofMEP模块和cables reducing single-use plastics in its products — as well as packaging, saving the equivalent of 40 tons of plastic waste a year.

此外,MACE为北美,U.K.和爱尔兰到达迪拜和越南的各地都设有海滩和河流清理程序,并在塑料废物中收集了估计的两吨。现在正在研究如何增加循环材料的使用。

承包商Multiplep在2019年7月推出了一项计划,其中两个主要焦点区域:消除了单用塑料和促进现有塑料物品的圆形。

该计划称为“7:5:3”,通过禁止避免的单用塑料物品来解决15个塑料类别,用替代品取代塑料或在生命结束时为塑料寻找新用途。

For example, Multiplex switched from plastic mastic tubes to foil mastic tubes at its 200 million pound ($282 million) Principal Tower project in London, saving more than 9,290 single-use plastic tubes and reducing the volume of packaging waste produced by 96%. Small steps like this can make a big difference if performed collectively.

While the international construction sector has a long way to go, firms can be pressed to pay greater attention to plastic waste and materials as nations outline plans to reach net-zero emissions by 2050 under the 2015 Paris Agreement.

建筑公司可以检查碳材料数据库,如美国碳排放量的库存,以规范不同种类的塑料碳水平作为确定如何以环保方式减少消费的起点。188bet滚球投注

从消费者浪费到施工资源

消费者的废塑料有可能成为建筑的重要资源。一些建筑产品 - 如管道和UPVC门和Windows - 已经包括一部分再循环材料,但建设中的新应用正在快速出现。

From an embodied carbon perspective, plastic is far less energy intensive to produce than traditional materials such as concrete and steel, especially when recycled. It also has engineering benefits such as its high strength-to-weight ratio, durability and resistance to corrosion. Combine all those characteristics, and you have an environmentally attractive proposition.

再生废塑料也用于加强道路表面的沥青。一家位于U.K的公司Macrebur,从塑料废物中熔化到沥青混合物中的塑料废物,以产生更强,更耐抗裂的路面。

桥梁是再生塑料的另一个竞争者。世界上最长的回收塑料桥,跨越30米,于2011年安装在苏格兰的Peeblesshire的Tweed河上。美国有几个,在系统中也是开创的。

从回收材料创建任何产品时的挑战是保证原料的质量。这需要技术和态度的变化 - 以考虑使用塑料作为资源而不是浪费。

随着世界各地的经济与如何迁移到新的循环经济,建筑业将成为过渡的重要组成部分。
