高科技混凝土工艺减少二氧化碳排放

High-tech Concrete Procedure Reduces CO2 Emissions

Cement is responsible for 7% of global man-made greenhouse emissions, making it the world’s second largest industrial source of carbon dioxide, according to the International Energy Agency. Data from the United States Geological Survey — the scientific agency of the US government — reveals that global cement production was responsible for about 4 billion pounds of CO2 emissions in 2017 alone.

国际能源机构称,生产水泥产生的温室气体占全球人造温室气体排放量的7%,是世界第二大工业二氧化碳来源。美国地质调查局(美国政府的科学机构)的数据显示,仅2017年一年,全球水泥生产就造成了约40亿磅的二氧化碳排放。

But a Canadian startup has invented a new system for making concrete that traps CO2 emissions forever and at the same time reduces the need for cement.

但一家加拿大初创公司发明了一种新的混凝土制造系统,该系统可以永久性地抑制二氧化碳排放,同时减少对水泥的需求。

CarbonCure’s system takes captured CO2 and injects it into concrete as it’s being mixed. Once the concrete hardens, that carbon is sequestered forever. Even if the building is torn down, the carbon stays put. That’s because it reacts with the concrete and becomes a mineral.

CarbonCure系统吸收捕获的二氧化碳,并在混合时将其注入混凝土中。一旦混凝土硬化,碳就会被永远封存。即使建筑被拆毁,碳也会保持原状。这是因为它与混凝土发生反应,成为一种矿物。
