Analysis of scrubber technology use to control SO2 emission in incinerators as a sustainable solution in plastic waste processing
No full textBackground: The use of wet scrubbers and dry scrubbers in incinerators using activated carbon and zeolite adsorbents is applied to control SO₂ emissions, serving as environmentally friendly waste processing tools. Methods: The principle of this test is that the exhaust gas from burning plastic waste with an incinerator is washed in a wet scrubber using water. Any remaining gas emissions are absorbed by zeolite and activated carbon through a dry scrubber. Testing of SO₂ exhaust gas emission concentrations is carried out on the incinerator, wet scrubber, and final chimney. Findings: The SO₂ exhaust gas concentration in incinerator combustion was 0.9685 mg/Nm³, the concentration after scrubbing using a wet scrubber was 0.1389 mg/Nm³, and the concentration after scrubbing using a wet scrubber and dry scrubber was 0 mg/Nm³. Conclusion: The use of a wet scrubber is effective in reducing SO₂ exhaust gas emission concentrations. The use of a dry scrubber is also effective in further reducing SO₂ exhaust gas emissions to zero. Novelty/Originality of this article: The novelty of this study lies in the combined application of wet and dry scrubbers with activated carbon and zeolite to achieve complete elimination of SO₂ emissions from plastic waste incineration, demonstrating a practical environmentally friendly approach
The voice of #SaveRajaAmpat: Digital movements against nickel mining
No full textBackground: The movement to against nickel mining in Raja Ampat was raised in early July 2025. The movement began with a post from Greenpeace Indonesia who were kicked out by security personnels when they protested against nickel mining in Raja Ampat in the middle of an event attended by industry professionals, government officials, experts, and representatives from various countries. This resulted in the digital community joining in to voice their opposition to Raja Ampat with the hashtag #SaveRajaAmpat. This research presents the circumstances that led the digital community to engage in the #SaveRajaAmpat campaign on social media and examines the effectiveness of social media campaigns. Methods: Using qualitative methods with a netnographic approach. The author used secondary data from Greenpeace Indonesia, organizational documents, news articles, and posts by X accounts about Raja Ampat.

However, the movement on social media was short-lived and faded due to minor victories achieved through the revocation of several companies permits and distraction by other issues. Conclusion: Social movement through social media are less effective, therefore it is necessary to unite social media movements and direct action with the spirit of disappointment towards the state and a spirit of resistance against capitalism so that the movement can be sustained. Novelty/Originality of this article: This change explains the various motivations of the digital community to engage in activism and explains why digital movements are less effective
One-pot catalytic conversion of glucose to 2,5-furandicarboxylic acid over NiO-modified ZSM-5 zeolites: Effects of reaction temperature and solvent ratio
No full textBackground: 2,5-Furandicarboxylic acid (FDCA) has gained increasing attention as a key bio-based intermediate for the production of polyethylene furanoate (PEF) and other sustainable polyesters, offering a viable alternative to fossil-derived monomers. Although FDCA is conventionally produced via oxidation of 5-hydroxymethylfurfural (HMF), direct one-pot conversion of glucose remains challenging due to the requirement for integrated catalytic functions and the strong influence of reaction conditions. Hierarchical zeolites modified with transition-metal oxides are promising for one-pot glucose-to-FDCA conversion; however, the effects of reaction temperature and solvent composition have not been systematically evaluated and are examined here using hierarchical ZSM-5, NiO-modified ZSM-5, and NiO catalysts. Methods: Hierarchical ZSM-5 was synthesized via a dual-template method and modified with NiO through an impregnation–spray technique to introduce redox-active sites. The catalysts were characterized using X-ray diffraction, Fourier-transform infrared spectroscopy, nitrogen physisorption, and Scanning Electron Microscope-Energy Dispersive X-Ray to establish correlations between structural, compositional, and textural properties and catalytic performance. Catalytic reactions were conducted at varying temperatures using a γ-valerolactone–water solvent system with different volume ratios. Findings: NiO-modified hierarchical ZSM-5 exhibited superior catalytic performance compared to the parent zeolite and NiO, achieving a maximum FDCA yield of 2.36% at 150 °C with an optimal γ-valerolactone–water ratio of 1:1. Higher FDCA yield over NiO-modified hierarchical ZSM-5 reflects the combined effects of hierarchical porosity, NiO species, reaction temperature, and solvent ratio. Conclusion: This study demonstrates that NiO-modified hierarchical ZSM-5 can promote one-pot glucose-to-FDCA conversion, with reaction temperature and solvent ratio identified as key parameters for performance optimization. Novelty/Originality of this article: This study provides a systematic assessment of the effects of reaction temperature and γ-valerolactone–water solvent ratio on FDCA formation over NiO-modified hierarchical ZSM-5 in a one-pot glucose conversion system, establishing catalyst and process design principles
