Abstract

Massive uses of conventional plastics have brought negative consequences to the aspects of sustainability and environmental friendliness of human activities, due to the problems concerning the availability of its raw materials and eventual wastes. One of the solutions to face these problems is by producing and using plastics that can degrade and be derived from renewable biomasses which are now known as bio-degradeable bioplastics.  At least, there are 4 kinds of plastics that can fulfill the criteria as being bio-degradeable bioplastics, namely starch-based plastic, cellulose-based plastics, PLA (polylactic acid), and PHA (polyhydroxylalkanoates). These four kinds of plastics have different characteristics, applications, strengths, and also weaknesses. In spite of the many challenges  in the uses of  bio-degradeable bioplastics to replace conventional plastics, newest technological development and the birth of stronger public awareness towards a more sustainable and more environmentaly-friendly life style have given stronger stronger forces to increase the uses and urgency of bio-degradeable bioplastics.

Abstract

As freshwater resource decreasing rapidly due to high rate of human population growth, many researchers have done studies to develop methods for producing freshwater supply. Seawater desalination is one of the method that has the credibility to be implemented. However, conventional seawater desalination processes suffer from a number of problems related to energy efficiency and cost. In spite of this, nanotechnology has been applied to the process. In this paper, we give an overview and explanations concerning the roles of nanotechnology in seawater desalination processes which consist of pretreatment, reverse osmosis (RO), and disinfection. In addition, the comparisons between conventional and nanotechnology-applied processes as related to its efficiency and effectiveness are also provided.
