安德鲁·登特认为，没有什么东西是应该扔掉的——当你将用过的食品容器、玩坏的玩具或者旧袜子扔进垃圾桶时，它们最终将不可避免地被运到垃圾场。但我们可以改进产品的生产和再生产方式。登特分享了关于节俭的几个例子，如利用和重新利用你需要的东西而不总是买新的，材料科学的进步——如用纳米纤维制作的电子产品，以及用酶让塑料变得可无限循环利用。

- Ninety-five percent of every single car that goes on the road gets recycled here.
- 所有在路上跑的汽车中，有95%都会被回收循环使用。
- And of that car, about 75 percent of the entire car actually gets used again.
- 而每辆车75%的部分又会被回收重新使用。
- That includes, of course, the old steel and aluminum but then also the plastics from the fender and the interiors,
- 回收的部分包括，废弃的钢和铝，还有那些来自挡泥板和汽车内部的塑料制品，
- glass from the windows and the windshield and also the tires.
- 车窗玻璃和挡风玻璃，以及轮胎。
- There's a mature and successful industry that deals with these old cars
- 有一个成熟的、成功的产业，专门处理报废车辆，
- and basically recycles them and puts them back into use as new cars or other new products.
- 对它们进行回收，并重新利用到新的汽车或其他产品中去。
- Even as we move towards battery-powered cars, there are companies that claim they can recycle up to 90 percent
- 甚至我们的电动汽车，一些公司宣称，它们最多可以回收再利用
- of the 11 million tons of batteries that are going to be with us in 2020.
- 到2020年所生产的1100万吨电池中的90%。
- That, I think, is not perfect, but it's certainly good, and it's getting better.
- 我认为，这并不完美，但已经非常不错了，而且还有改善的空间。
- The industry that's not doing so well is the architecture industry.
- 在这一方面做得不太好的是建筑行业。
- One of the challenges with architecture has always been when we build up, we don't think about taking down.
- 其中一个原因是，我们只考虑建筑物建造，却不考虑拆卸的问题。
- We don't dismantle, we don't disassemble, we demolish.
- 我们不会拆卸或拆除建筑物，只会直接摧毁。
- That's a challenge, because it ends up that about a third of all landfill waste in the US is architecture.
- 这是一个挑战，因为美国垃圾填埋场中有三分之一都是建筑垃圾。
- We need to think differently about this. There are programs that can actually reduce some of this material.
- 我们应该想想怎么解决这个问题。有些做法可以减少建筑垃圾的产生。
- A good example is this. These are actually bricks that are made from old demolition waste, which includes the glass, the rubble, the concrete.
- 举一个比较好的例子，这些砖头是用建筑废渣料生产的，其成分包括玻璃、瓦砾和混凝土。
- You put up a grinder, put it all together, heat it up and make these bricks we can basically build more buildings from. But it's only a fraction of what we need.
- 把它们放进研磨机中加热，生产出的砖头又能被用于更多建筑中去了。但这只是很小的一部分。
- My hope is that with big data and geotagging, we can actually change that, and be more thrifty when it comes to buildings.
- 我希望，我们能利用大数据和地理定位改变这种状况，把节俭这个概念运用到建筑业中。
