Other thinkers have written before that “waste is material at the wrong place” and that “waste is a resource”. According to recent global statistics, more than 50% of the energy we extract from primary sources is wasted in the various transformation and storage steps, leaving less than 50% in use. The situation is even worst for materials, with more that 70% of the primary materials being wasted after a first use. We now fully realize that the planet's primary resources are finite and that the anthropogenic waste that accumulates in the soil, oceans and atmosphere has negative, widepsread and lasting impacts. These observations make us realize that we do not use primary resources efficiently and do not value waste. From the elemental standpoint, “waste” is made up of the same chemical elements as the materials we value (i.e. materials we use daily and want in our backyard) but that happens to be in the wrong molecular arrangement or place. The transition to a sustainable use of resources requires a system’s thinking that features the use of renewable energy and materials, as well as efficient and closed-loop processing at all scales.

其他思想家以前曾写道，“废物是放在错误地方的材料”，“废物是一种资源”。根据最近的全球统计数据，我们从一次能源中提取的能源中有50%以上被浪费在各种转换和存储步骤中，剩下的不到50%。材料的情况甚至更糟，超过70%的原材料在第一次使用后就被浪费了。我们现在充分认识到，地球的主要资源是有限的，积累在土壤、海洋和大气中的人为废物具有负面、广泛和持久的影响。这些观察使我们认识到，我们没有有效地利用初级资源，也不重视浪费。从元素的角度来看，“废物”是由与我们所重视的材料（即我们日常使用的材料和我们后院想要的材料）相同的化学元素组成的，但这些化学元素恰好处于错误的分子排列或位置。向可持续利用资源的过渡需要一种系统思维，其特点是使用可再生能源和材料，以及在所有规模上进行高效和闭环处理。
