Green Chemistry for the Production of Biodegradable Polymers as Solid Substrate and the Formation of Sustainable Biofilm

Abstract:

Conventional plastics derived from the fossil fuels pose a threat to the global environment due to their non-degradable nature. Problems associated with global warming and solid waste management has generated interest in the development of novel plastics. Theses while retaining the desired properties of conventional synthetic plastics must also are degradable. Among the various biodegradable plastic available, there is growing interest in the group of polymers known as polyhydroxyalkanoate (PHA).The present investigation is based on (i) Biodegradation of Bioplastic with biological approaches (ii) Production of cost effective Bioplastic. Cost of bioplastics serves as a hindrance to the development of bioplastics for food and drink packaging as the plastic is produced by harvesting the natural resources thus there is utilization of the agricultural waste and also reduces the overall cost of the product. As in the case of petroleum based plastic production, there is the need of huge sum of energy which consumes the non renewable sources which is getting depleted. Thus, we can conclude that having a cost effective bioplastic in our near future. This plastic will be replacing the commercially available plastic very soon. The bioplastic produced is also degradable. It thus reduces the waste accumulation on the areas surrounding us. It is also suggested that on degradation it does not produces any toxic to the environment and no harmful gas is emitted thus no greenhouse gas and no global warming. This would be an environment friendly product.
