Abstract

It is projected that global waste production will reach 3.4 billion tons by the year 2050, with 33% of this waste not managed in an environmentally sustainable manner. Since the beginning of the 21st century, there has been a significant increase in household and industrial waste, which poses major environmental, public health, and policy challenges. This study employed a systematic literature review (SLR) approach and bibliometric analysis to map global solid waste research trends. The data were collected in three stages: article identification, eligibility screening, and metadata extraction. These data were then analyzed using VOSviewer 1.6.20. A comparative analysis revealed a paradigm shift from a linear approach towards a circular economy model between 2004 and 2024. The period 2014-2024 signifies the consolidation of the concept of sustainability, marked by a 72% increase in network complexity. The research focus underwent a shift from municipal solid waste management to circular economy systems, which are now linked to 38% more derived concepts. New subjects, such as plastic pollution and post-consumption plastic waste, have emerged as predominant themes in 28% of recent publications. The density visualization demonstrates the most significant concentrations in the domains of circular economy and municipal waste management. There has been a marked increase in research activity in recent years, particularly with respect to plastic pollution and waste valorization.

Abstract

The increase in laundry service activities in Indonesia has an impact on the high water pollution due to the disposal of laundry waste containing chemicals such as COD, TDS, and Phosphate. Laundry waste, which is discharged directly into the environment without treatment, can lead to eutrophication, deterioration of water quality, and the death of aquatic biota. Phytoremediation with a constructed wetland system using genjer plants (Limnocharis flava) was chosen as an environmentally friendly, and low-cost treatment alternative. This study aims to analyze the effectiveness of reducing COD, TDS, and Phosphate levels of laundry waste with genjer plants in the constructed wetland system, as well as to analyze the relationship between the 0, 4th, 8th and 12th day stay time on the reduction of parameters before and after treatment. Preliminary experiments used a control reactor (without plants) and a treatment reactor (10 plants). The results of this study showed the ability to set aside the largest removal in the treatment reactor at COD levels of 88,147%, TDS of 12,776% and phosphate of 14,911% on day 12.. This shows that the constructed wetland method is relatively effective to be applied as laundry waste treatment.
