Summary
Natural textile waste can be transformed into biodegradable water-absorbing geocomposites (BioWAGs) to enhance plant growth and conserve water. This sustainable technology significantly boosts grass biomass and root development, aligning with circular economy principles.
Area of Science:
- Environmental Science
- Materials Science
- Agricultural Science
Background:
- Increasing environmental pollution from textile waste necessitates sustainable management solutions.
- Natural textile waste, particularly from sheep farming and fibrous plants, offers potential for environmental applications.
- Developing innovative technologies for waste valorization is crucial for sustainable development.
Purpose of the Study:
- To evaluate the effectiveness of biodegradable water-absorbing geocomposites (BioWAGs) derived from natural textile waste under field conditions.
- To assess the impact of BioWAGs on plant vegetation, specifically focusing on water conservation and biomass production.
- To analyze the influence of BioWAGs on key plant growth parameters, including fresh/dry matter, root system development, and relative water content.
Main Methods:
- Development of biodegradable water-absorbing geocomposites (BioWAGs) from natural textile waste.
- Field experiments to evaluate BioWAG effectiveness on selected grass species.
- Analysis of plant growth parameters: fresh and dry matter, root system development, and relative water content (RWC).
Main Results:
- BioWAGs significantly increased fresh mass of grass shoots by 230-420% compared to the control.
- The root system of grass species treated with BioWAGs showed increments of 130-200%.
- The study confirmed the high efficiency of BioWAGs in supporting plant vegetation and water saving.
Conclusions:
- Biodegradable water-absorbing geocomposites (BioWAGs) are a highly effective technology for enhancing plant vegetation and conserving water.
- The reuse of natural textile waste in BioWAGs aligns with circular economy principles and sustainable development goals.
- This innovative technology presents a viable solution for managing textile waste while promoting ecological benefits.
