Recently, the recycling industry and researchers focus on the recovery of high value platinum group metals (PGMs) from spent automotive catalysts. However, the remaining carrier was usually buried as solid wastes. It’s not only resulted in the reduction of the landfill space but also wasting its characteristics similar with zeolites. The zeolite is a sorbent that has the advantage of high selectivity, water resistance, extensive use, high plasticity, good regeneration usage and suitable for adsorbing VOCs. Due to the rapid development of China, large quantities of air pollutant are exhausted and transported to Taiwan or other countries through the change of seasons. They pose a threat to human health and living environment. Therefore, the main purpose of the study is to combine the reduction of solid wastes with the removal of air pollution by following methods. First, the technology with the features of fast reaction and low cost is used to regenerate the carrier and enhance its specific surface area. Second, making a filter cloth which have the ability of adsorbing CO2. Third, the filter cloth would also be set into the air cleaner to execute the elimination experiment of indoor air pollutants (CO2, formaldehyde, PM10 and PM2.5) at the office (a small space with the intensive number of people) and laboratory (storage of various organic solvent). At last, the removal capacity of generated catalyst would be analyzed and investigated. In summary, the aim of the study is to reduce the amount of solid wastes and remove indoor air pollutants for a better living environment.

沸石為一具有選擇性、耐水氣、用途廣泛、可塑性高與再生使用率佳之吸附劑。此技術將達到固體廢棄物減量與空氣污染物的去除進行跨領域的結合，並發展一套快速且低成本的再生技術，將汽車廢觸媒載體予以活化及增加比表面積，利用將可吸收CO2之技術轉移至載體上，並製成濾網。應用於去除室內空氣污染物，達到改善室內空氣品質之目的。

此技術應用的層面主要可分為兩個區塊。
1.廢棄物再利用：此技術將廢棄物處理再生後加以改質，給予其新的附加價值與功用。
2.室內空氣清淨：本技術可以替代空氣清淨機的濾材。
