阅读下面短文,回答题.When tom Szaky sees a juice container thrown away, he doesn' t see rubbish; he sees a pen- cil case. Sweet wrappers (包装纸) ? A beautiful kite. But these are not the imaginings of a dream- er. For the 28-year-old CEO of Trenton, New Jersey-based TerraCycle, they're a business model. The fast-talking Szaky is leading the new industry of upcycling. Instead of recycling ( shred- ding or breaking down materials and enabling them to be reproduced as other products), TerraCycle takes packaging headed for landfills(垃圾填理) and reuses it--more or less whole. TerraCycle' s85 employees make nearly 200 products, sold at shops such as Petco, Krnart, Whole Foods Mar-ket, and Target.
Szaky's $ 7.4 million company, now also moving ahead in Mexico, Canada. the United Kingdom and Brazil is a far cry from the business he founded with classmate Jon Beyer in 2002 as a freshman at Princeton University. The two entered a business competition with a plan to sell an organic plant fertilizer(有机肥料) made from worm waste. They lost the competition but started the business anyway.
With their goal--to make products entirely out of rubbish--suddenly clear, Szaky knew thetime was right to drop out of Princeton.
TerraCycle' s first product used dining-hall waste to feed the worms and thrown-away bottles to package the fertilizer. The result: a cheap, green breakthrough. Word spread, and in 2004, Home Depot began carrying the fertilizer in its Canadian stores.
to Szaky, waste does not exist in nature. TerraCycle is a "second chance" employer of, say, a piece of furniture, an ice-cream container. As Szaky points out: "The biggest problem with most green, fair-trade, and organic products is that they tend to cost more. At TerraCycle, everything is made from rubbish, and rubbish is free. People should be able to protect the planet without having to pay a cost for that right. "
Who is tom Szaky? A．A student at Princeton University.
B．The manager of a food company.
C．An employee of Home Depot.
D．CEO of TerraCycle.
