Abstract: This paper explores the dynamics between nuclear plants, political parties, and anti-nuclear movements in Taiwan. By analyzing the development of anti-nuclear movements in Taiwan, this research highlights the complex role of political parties in the anti-nuclear movements. The environmental impact of nuclear power plants is a multifaceted issue that involves considerations ranging from emissions to waste management and potential accidents. Consequently, politics plays a significant role in shaping the environmental impact of nuclear power. The politicization of anti-nuclear energy in Taiwan is a complex and multifaceted issue. Taiwan has experienced significant debate and division over the role of nuclear energy in its overall energy strategy. One major factor contributing to the resurgence of anti-nuclear power in Taiwan is the Fukushima Daiichi nuclear disaster in 2011. This event heightened public concerns about the safety of nuclear power, leading to increased opposition to nuclear energy and calls for its phase-out. Furthermore, Taiwan's unique political landscape, with its own domestic and international pressures, has also contributed to the politicization of this issue. In recent years, the Taiwanese government has navigated this complex landscape by outlining plans to gradually reduce its reliance on nuclear power while increasing investments in renewable energy sources. However, the issue remains politically charged and continues to be a subject of ongoing debate and activism. Overall, the politicization of anti-nuclear energy in Taiwan reflects larger societal concerns about environmental safety, energy independence, and the balance between economic development and sustainable practices.

Abstract: Plastic waste has given rise to numerous environmental issues due to its non-biodegradable nature. This research suggested the incorporation of polyvinyl chloride (PVC) plastic powder as partial cement replacement in concrete. The replacement levels of PVC waste powder (PWP) were 0%, 4%, 8%, 12%, and 16% by mass of cement. The concrete was cured for 7, 14 and 28 days before being subjected to mechanical strength tests (compressive and flexural strengths) and durability tests (porosity, water absorption, gas permeability, chloride attack tests). Results revealed that the workability of concrete with substitution of PWP as partial cement replacement increased in which replacing 16% of cement with PWP increased the workability by 56% as compared to the control specimen. The mechanical strength of concrete and durability decreased with the increase in PWP content. Nevertheless, up to 12% of PWP can be added into the concrete as the compressive strength was only 9% lower than the control specimen. All specimens achieved the required strength of 13.8 MPa to be classified as loadbearing concrete masonry units as specified in ASTM C90 – 14. Overall, only low quantities of PWP should be used to replace cement in concrete to maintain the quality of the concrete.
