二十世紀，人們並不關注環境議題，對綠色產品興致缺缺，因此使用了許多破壞地球環境產品。隨著人口逐年增加，人們對需求也跟著年年上升，為了應付逐年上升之需求，則必需開採更多資源以滿足人們的需求，造成環境上的破壞日益嚴重。為使環境能永續發展，回收再製已是目前之趨勢。
本篇研究主要延伸Saadany & Jaber (2010)，製造商生產產品銷售至市場後，為使回收品的品質提升，因此投入一個努力值建立回收機構，藉由此機構回收品質較高之回收品，使再製、銷毀成本降低；同時也可提升再製品之售價，因而提升利潤。本篇主要探討是如何用最低價格從消費者身上收購較高品質之回收品，在回收價格及回收品質影響銷售價格情形下，能使訂出之售價最為合理，使成本大幅降低，且在回收價格、回收品質及再製品售價三者間取得最佳組合。

Twentieth century, people are not concerned about environmental issues, seem to not interesting in green products, so using a lot of product to damage the global environment. As the population increases of every year, demand are also followed an increase, year after year to meet rising demand, must extract more resources to meet people''s needs, resulting in increasingly serious environmental damage. Of the environment to sustainable development, recycling system is the current trend.
This study mainly extends Saadany & Jaber (2010), manufacturer sells to the market, in order to enhance the quality of recycled product, so investment of the effort in order to establish recovery mechanism, using the mechanism to recycle higher quality of recycled product, not only reduce the cost of the destruction, but also to enhance the price of remanufactured product, and thus improve profits. In this paper is to explore how consumers buy the lowest price from a recycled products of high quality, recycling prices and quality which is effect the sales price, set the price to make the most reasonable, so that significant cost reductions. In the purchasing price、recycle product quality、remanufactured product of price to achieve the best combination of price among the three.
