“…64 In addition, previous research confirms that plants can be used as a phytoremediation approach to treat synthetic dye; certain plants grown in hydroponics systems have shown to be effective. 65,66 Further research is necessary to confirm the viability of using natural dye plants to treat the dye effluent of the PCTW in the hydroponics system for a circular approach. This research aligns with broader intentions to close the circularity gap of material reuse, as proposed by scholars in the recent Circular Cut report.…”

Aligned with the circular economy framework, this study aims to address pertinent research gaps regarding material and chemical properties of clothing and suitability for closed-loop applications. Primary research questions include: (1) what are the material and chemical properties of post-consumer textile waste from a sustainable fashion take-back program; (2) which natural post-consumer textile waste is most suitable to support the growth of natural dye plants in a hydroponics system; and (3) can the use of post-consumer textile waste in a hydroponics system be scaled to support a circular fashion supply chain? This study focuses on wool, cotton, linen, silk, rayon, and Tencel® lyocell as substrates to nurture the growth of purple basil, a natural dye plant. Vertical hydroponics is a farming method that uses nutrient water to grow plants in place of soil throughout the year. The system can be indoors, making resourceful use of limited space available and the water is recirculated. Standard hydroponic substrates, like peat moss and rockwool, have good porosity for oxygen transport and suitable moisture holding capacity for nutrient delivery. In this study, we compared the performance of the standard hydroponic substrates with various textiles. The impact on water quality, color release, moisture wicking, stability against degradation, and survival rate of the plants was used to evaluate suitability in the application. Wool, silk, and Tencel lyocell demonstrated good durability in the hydroponic system, like peat moss and rockwool, during the first growth cycle. During the second growth cycle, protein fibers—wool and silk—supported plant survival at a greater capacity than Tencel lyocell. Future research can confirm that wool and silk can support the growth of natural dye plants with a larger sample size. This research aligns with several circular economy objectives and provides a model for future research to support circular fashion supply chains.

“…The introduction of synthetic dyes has substantially reduced the usage of natural dyes [3] because synthetic colors are brighter, cheaper, and allow mass production [4]. Despite these benefits, however, synthetic dyes are detrimental to human health, cause substantial environmental pollution [5,6], and damage ecosystems [7]. Synthetic dyes generate industrial waste, the largest contributor to water pollution.…”

Natural dye is one of the solutions to alleviate environmental damage caused by the textile industry. Existing synthetic dyes have been proven to adversely affect the environment and human. Hence, revisiting natural dyes becomes a correct decision to alleviate existing environmental problems. Eco-print is one of the natural dyeing methods done by using plants typically found in the surroundings. This method has become the subject of various developments, both in its mordanting and making processes. Its visual aesthetics should also receive attention to avoid stagnation. Further development and innovation are necessary. The purpose of this study was to develop the visual aesthetic aspect of the eco-print method. It particularly focused on developing the design and production technique in terms of concepts, materials, and working techniques. This work also adopted a screen printing technique to enrich the motifs and colors. The method utilized in this research was art-based research with the premise of adapting artistic creativity to social research using an artistic practice approach because both are holistic and dynamic. The result showed that eco-print and screen printing methods could be combined, as the latter significantly enhance the eco-print product’s visual aesthetics. However, the result of this combination exhibited poor color fastness, implying the need for further study.
