This work aims to understand the requirements of converting denim waste (as source of cellulose) to biopolymer for fabrication of bioplastic as an alternative to the non-degradable plastics that are currently used as single-use packaging. The success of this project will lead to the reduction of the use of fossil-fuels and reliance on non-renewable resources. The annual production of jeans is about 3.6 billion pairs. While an average pair of jeans weighs 600g, the total textile Jeans consumption is 2.16 million tons a year, yet discarding of the used denim has a huge impact on the environment. Denim materials are recycled only on a limited scale, though few research projects are reported to convert denim to high added value products e.g. production of pigments or aerogel. It seems there is a long way for commercialisation of these outcomes. Furthermore, the proposed recycled solutions may not be the only resolution for recycling the huge amount of produced denim. Use of cellulosic based biopolymer for packaging is not new, however, the current products don’t meet the required shelf life. This project for the first time uses abundant denim waste to be converted to bioplastic with enhanced shelf life.
Dr Naebe's group has studied the development of bioplastic from cotton gin trash/PVA and fabricated transparent packaging film from PVA/ nanocrystal cellulose from hemp waste with enhanced mechanical properties and degradation. We also initiated preparation of gel solution from pure cotton linters and starch (unpublished data), using thermochemical technique. Based on our ongoing research, we aim to further investigate into fabricating biopolymer from denim waste, enforced with cellulose nanocrystal, to potentially convert it into plastic film while standing the required shelf life.
This work aims to understand the requirements of converting denim waste (as source of cellulose) to biopolymer for fabrication of bioplastic as an alternative to the non-degradable plastics that are currently used as single-use packaging.
This project will provide:
- A new route and purpose for denim waste to produce biopolymer/bioplastic.
- A new understanding on the thermo-chemical interaction of denim waste in producing cast-able bio polymer solution.
- A new knowledge on denim waste combination with other bio-based material, e.g., nanocrystal cellulose and starch.
The successful candidate will gain skills and knowledge in a broad range of techniques and scientific areas in this interdisciplinary project on the interface of chemistry, polymer and materials science. In addition they will gain knowledge of a range of characterisation techniques in material science. The understanding from this research will further assist our ongoing research in improving the properties of the biodegradable film made of cotton wastes that can be used as an alternative to the current synthetic plastics. This project aligns with IFM`s vision in leading innovative & transformative research in re-designing materials and advanced technologies for IFM`s Circular Economy strategy.
This research will assist in re-designing materials with extraordinary functionality from waste. The finding from this research will open up new opportunities for textile waste to be applied in new areas such as packaging to accelerate the transition to a circular economy.
Applications will remain open until a candidate has been appointed
