We could reduce the clinker ratio even more.

我们可以进步降低熟料比。

But producing high-quality clinker is a complex science.

然而，生高质量熟料是门科学。

To produce clinker, you need to maintain a temperature of over 1,400 degrees Celsius.

要生熟料，需要将温度维持在摄氏1400度以上。

So one strategy is to find a substitute for the clinker.

所以个策略是找到熟料替代品。

Most of the emissions come from the process of producing clinker, the key ingredient in cement.

大部分排放来自生水泥熟料过程，熟料是水泥关键成分。

In North America, clinker accounts for about 90% of cement due to safety standards.

在北美，由于安全标准，熟料约占水泥 90%。

Startups have been in a race to develop a new kind of green cement that avoids clinker altogether.

初创公司直在竞相开发种完全不含熟料新型绿色水泥。

They talked outboard-motors and debated clinker versus carvel until their mugs were empty.

他们谈论舷外发动机， 争论熟料还是卡维尔， 直到他们杯子都空了。

Once it goes through the kiln it becomes a material called clinker: the key binding ingredient in cement.

旦进入窑炉，它就变成了种叫做熟料材料：水泥关键粘合成分。

China uses less clinker in their cement than the global average and they have at least one carbon capture project in the works.

中国在水泥中使用熟料比全球平均水平要少，而且他们至少有个碳捕获项目正在进行中。

Experts emphasized one new cement mixture that gets the clinker ratio safely down to 50% by supplementing it with more clay and unprocessed limestone.

专家们强调了种新水泥混合物，通过添加更多粘土和未加工石灰石，可以将熟料比例安全地降低到 50%。

These reductions will help in reducing emissions… but until we find a scalable, zero-emission cement, any clinker production at all will inevitably have process emissions.

这些减少将有助于减少排放… … 但在我们找到可扩展零排放水泥之前，任何熟料生都将不可避免地生过程排放。

Ecocem, an Irish startup, is making cement that uses less clinker, the intermediate material derived from the heated limestone, and thus emits less carbon.

Ecocem 是家爱尔兰初创公司， 正在生使用较少熟料（从加热石灰石中提取中间材料） 水泥， 从而减少碳排放。

So the secret sauce is to produce cleaner and higher quality clinker, because the higher the quality of the clinker, the less of it you will need to produce cement ultimately, and therefore the less emissions you will generate.

而解决方法就是生更干净、更高质量熟料，因为熟料质量越好，生水泥所需熟料就越少，进而降低二氧化碳排放量。
