Probably right now we're talking about 30 or 50 pounds at a time, " Scheer says.
可能现在我们一次能得到30磅或50磅，”舍尔说。
Listen for a few moments as Warren Scheer reads the beginning of Chaucer's famous "Canterbury Tales."
让我们听听沃伦·舍尔朗读的坎特伯雷故事集的开始部分。
At the moment, Scheer says, his team has succeeded in displacing up to 35 percent of the petroleum in traditional plastics with algae.
现在，舍尔说，他们的研发小组已成功地将传统用来制造塑料的石油35%的成分替代为海藻。
Scheer stresses that his team's main goal is to derive a monomer—the building block of the polymers most of us call plastics—entirely from algae biomass.
舍尔强调他们的主要目标在于研发一种单体物质-我们大多数人称为塑料的一种聚合物的构件---完全来源于海藻这种生物质原料。
Creating plastics that are biodegradable is important, Scheer says, because just 3.5 per cent of polypropylene plastic in the United States gets recycled.
舍尔说，生产生物可降解塑料很重要，因为在美国，只有3.5%聚丙烯塑料得到回收利用。
The way people in their 40s and those in their 20s used the Web did not differ much, Scheer said, but the difference to someone in their mid-fifties was significant.
他说，40多岁的人和20多岁的人在使用互联网方面差别并不大，但若与50多岁的人相比，这一差别就很显著。
The success is bittersweet for Scheer, who was born in Paris but has become known as the one of the "grandfathers" of the bio-plastics industry in the United States, rather than in his home country.
对舍尔来说，这种成功苦乐参半。他出生在巴黎，但是，他的生物塑料业“始祖”的声誉是在美国确定的，而不是在他自己的家乡。
