ABSTRACT
As global awareness of environmental sustainability increases, addressing the contamination of water sources has become a crucial priority. VersaBent 2.0 was made from natural resources of polysaccharides and biomass, which is proposed as a green chemistry strategy for the environment. VersaBent was prepared by immobilizing yeast into the matrix of sodium alginate beads. Interestingly, this innovation is upgrading from VersaBent 1.0. Innovatively, VersaBent 2.0 is made up of Polyvinyl alcohol (PVA) synthetic polymer that is cheap and non-toxic, which will be added to produce strong and durable beads compared to VersaBent 1.0. Thus, this innovation highlights the development of efficient adsorbents to treat contaminants such as dyes, food colouring and heavy metals. Then, the VersaBent 2.0 can be used to remove the target contaminants via adsorption process. This innovative product also has a high commercialization potential due to the low cost of raw materials and production.
Key words: dye, food colouring, textile, adsorption, biopolymer
