There is a connection. Just as plastic is derived from petrochemicals, bitumen is produced as a by-product of refining oil.

其中有一个联系。塑料源自石油化工，而生出的沥青是精炼油脂的副。

The vessels brought petrochemicals to Brazil early this year and were due to load corn before returning to Iran.

两只船于今向巴西输送了石油化工，在返回伊朗之前还要装载一些玉米。

We make the exact same petrochemicals, except we don't use the petroleum; we use waste plastic.

我们也生完全相同的石油化工，除了我们不使用石油，而是使用废弃塑料。

Whether it's heavy metals or petrochemicals.

无论是重金属还是石油化工。
