我國廢機動車輛回收數量有逐年增加之趨勢，而廢機動車輛經回收後，仍有部分非金屬物質，如廢泡棉、廢玻璃，因體積較大，價格較低，故過去都以直接粉碎送往焚化爐及掩埋場處理，但因現有焚化爐與掩埋場處理量能有限，因此若能回收再利用，提升其環境價值，對於廢棄物資源化亦有重大效益。 本研究已進行車用廢玻璃、廢泡棉與廢紙纖維及木材粒片進行生產水泥板材試驗，其中包含廢紙纖維與廢玻璃生產水泥複合板，廢玻璃添加率與水泥比例不同，複合板之板性因廢材的添加將使抗壓強度增加，抗彎強度雖無法增加，可能因其與水泥接著性較差，可用於建材裝飾板使用。 並利用車用廢玻璃生產耐燃材料，分析結果顯示，隨著廢玻璃的增加可以降低燃燒過程中所產生的熱量，同時也可以保護合板和延遲合板的燃燒。利用玻璃在高溫狀態下，熔融與溶解而形成玻璃體的過程，使其與無機物料相互作用形成共熔物質的特性，從而達到接替有機成膜物質，承受在高溫狀態下的耐熱、抗氧化、防腐蝕等物理機械作用。 另外利用車用PU泡棉進行生產吸附材試驗，將碳化後PU泡棉以比表面積分析儀進行分析，經過梯度升溫的比表面積較大，未來可吸附雜質的能力將會比直接升溫來的好，期末將嘗試以較低溫的條件試驗，以提高吸附材之比表面積提升吸附能力。 利用車用廢泡棉與廢棄生質物進行混合造粒後，熱值可達5000 kcal/kg以上，生產固態生質燃料，將可用於能源用途，因此本計畫已進行燃燒鍋鑪及熱交換器的製造，所造之顆粒進行燃燒後，可將木屑進行乾燥，所排放之污染物亦低於國家標準，可達成能源循環再利用用途。

The recycling quantity of waste motor vehicles in China has a trend of increasing year by year. After recycling of waste motor vehicles, some non-metallic substances, such as waste foam and waste glass, are used in the past because of their large volume and low price. It is sent to incinerators and landfills for treatment. However, due to the limited processing capacity of existing incinerators and landfills, if it can be recycled and reused, and its environmental value will be enhanced, it will also have significant benefits for waste recycling. In this study, vehicle waste glass, waste foam and waste paper fiber and wood pellets have been tested for cement board production, including waste paper fiber and waste glass to produce cement composite board. The addition rate of waste glass is different from that of cement. The board property will increase the compressive strength due to the addition of waste materials. Although the flexural strength cannot be increased, it may be used for building materials decorative panels because of its poor adhesion to cement. The use of waste glass for vehicles to produce flame-resistant materials, the analysis results show that with the increase of waste glass can reduce the heat generated in the combustion process, but also can protect the burning of the plywood and delayed plywood. The process of forming a vitreous body by melting and dissolving the glass at a high temperature, and interacting with the inorganic material to form a eutectic substance, thereby achieving the replacement of the organic film-forming substance and withstanding the heat resistance, oxidation resistance and prevention at a high temperature. Physical and mechanical effects such as corrosion. In addition, PU foam is used to test the production of adsorbent materials. The carbonized PU foam is analyzed by a specific surface area analyzer. The specific surface area after gradient heating is large, and the ability to adsorb impurities in the future will be better than direct heating. At the end of the period, attempts will be made to test at a lower temperature to increase the specific surface area of the adsorbent material to enhance the adsorption capacity. After mixing and granulating waste waste foam and waste biomass, the calorific value can reach 5000 kcal/kg or more, and solid solid fuel can be produced for energy use. Therefore, the project has carried out combustion boilers and heat exchangers. After the granules are burned, the wood chips can be dried, and the pollutants discharged are also lower than the national standards, and the energy recycling can be achieved.
