​An Introduction to the Circular Economy



Want to learn more from one of the top recycling nations in the world? Inside this report discover how Taiwanese companies are using waste as a resource in a variety of sectors with a special focus on heavy industry. You can explore how these companies capitalized on proven circular economy practices to develop environmentally and economically sound business models.



LCA of Recycling Cobalt Reactive Catalysts ​

全球消費性電子及電動車的使用量持續增加,但隨之而來的是電池生產對環境的影響越來越大,回收用於製造電池的元件是否會帶來任何環境效益? 本報告以生命週期評估法,分析再生觸媒對整體環境衝擊,並以新料觸媒作為比較基礎。主要結果顯示,再生觸媒因不須開採鈷錳金屬,在對環境具有顯著效益。


Globally consumer electronics and electric vehicle use continues to increase, yet with this comes increasing environmental impacts from battery production. Would recycling parts of the elements used to make batteries lead to any environmental benefits? This LCA report found that overall recycling battery catalysts have a lower environmental impact, and offer more benefits because they reduce the need for mining cobalt and manganese.



LCA of RDF from Waste Paper​

使用不可回收的廢物來減少公司的燃料費用,也可減少垃圾掩埋的費用,但是潛在的環境影響呢?本報告以生命週期評估法,分析紙廠製紙過程產生的廢紙排渣,透過製程再製為 RDF 作為鍋爐輔助燃料,對整體環境的衝擊。主要結果顯示,廢紙排渣再製為 RDF 對整體環境衝擊僅燃煤的20%。


Using non-recyclable wastes for energy reduces fuel expenses for companies and reduces landfill usage. But what about the potential environmental impacts?  Results from this life cycle analysis on paper waste fuel show that it is 80% better for the environment than coal. Using this type of fuel to replace coal would have noticeable environmental benefits. This has important policy implications for Taiwan as currently this type of RDF is limited to internal factory use only.



LCA of Wood Pellets and PKS ​



To improve air quality and fight climate change countries use plant-based energy, or biomass, as a substitute for fossil fuels. This report looks at the total life cycle impact of using wood pellets and palm kernel shells (PKS) as fuel for energy in Taiwan. This study shows wood pellets and PKS are at least 70% cleaner than coal.  These findings suggest that for Taiwan to quickly clean up it’s emissions it can use more biomass instead of coal.



LCA of Waste Tire Pyrolysis

隨著全球汽車里程總數的攀升,輪胎的使用隨之增加,但與此同時,這也使得全球每年增加 10 億噸的廢棄輪胎。本報告以生命週期評估法,分析廢輪胎熱裂解應用對整體環境衝擊,並以重油作為比較基礎。整體研究結果顯示,回收廢輪胎再製為熱裂解油的衝擊較重油低。


With an ever-rising increase in wheeled travel, from cars and trucks to scooters, tire consumption is also increasing. Currently the world produces 1 billion tons of waste tires each year. Pyrolysis is a common method to process waste tires into usable fuel. The main result this LCA report shows that environmental impact of pyrolysis oil is 80% of that of heavy oil.



The Case Studies of Industrial Symbiosis



Circular parks developed with the concept of industrial symbiosis have become one of the major policies for governments across the world to promote circular economy, increase resource utilization and reduce greenhouse gas emissions. This report focuses on introducing successful cases and related policies in Taiwan.
