这项工作的重点是制定一个简明的表示材料回收的潜力，产品在生命周期结束。要做到这一点，我们提出了一个类似于“舍伍德情节”的模型，但产品，而不是稀释的混合物。这种差异反映在材料成分和用于两种不同应用的处理系统上。产品回收系统的成本估计开发使用香农的信息理论。由此产生的模型是能够解决的材料回收潜力的范围广泛的最终的生命周期产品有很大不同的材料成分和回收率在美国的产品设计的历史趋势的初步数据表明，一个显着的转变，减少可回收的产品。
This work focuses on developing a concise representation of the material recycling potential for products at end-of life. To do this we propose a model similar to the "Sherwood Plot", but for products rather than for dilute mixtures. The difference is reflected in the material composition and the processing systems used for the two different applications. Cost estimates for product recycling systems are developed using Shannon's information theory. The resulting model is able to resolve the material recycling potential for a wide range of end-of-life products with vastly different material compositions and recycling rates in the U.S. Preliminary data on historical trends in product design suggest a significant shift toward less recyclable products.
