Obligation to use the best available technology (BAT) in the protection of the environment is envisaged in many international treaties. It is not only legal, but also moral obligation. Treaties concluded under the auspices of the International Maritime Organization (IMO) that aim at the protection of the environment and the prevention of pollution from ships, enshrine the precautionary principle which encompasses the obligation to use the best available technology. Many IMO treaties consider technological development, some of them even drive it, however, not all standards are based on the best and the newest solutions. The discussion at the IMO’s Marine Environment Protection Committee regarding the energy efficiency design index demonstrates the impact of political and economic interests on the text of adopted standards. The Initial IMO strategy on the reduction of greenhouse gas emissions from ships identifies levels of ambitions consistent with the Paris Agreement. In the shipping industry this will be achieved, if the adopted standards were based on the best available technology.
The textile sector is considered as the 3rd largest source of water pollution and land degradation during 2020. 20% of the world’s water pollution is linked with textile production and utilisation. Textile washing releases 14 million tons of microplastics, according to European Environmental Agency estimates. Wastewater Treatment Plant [WWTP] has declared everyday normal releases of more than 4 million MP particles because of its tiny size (<5 mm) and low thickness (<1.2 g/cm3). Electrochemistry for the removal of tinny pollutants is recognised as an efficient treatment mechanism. The main aim of this research paper is to identify the efficiency of electro-coagulation technology using Fe and Al as anode and cathode in microplas-tic removal from Thailand’s textile industries. Results show the maximum 100% microplastic removal efficiency with pH 10 at a current density of 30 A/m2 within 60 minutes of the current supply. This paper helps to understand the role of electro-coagu-lation in Thailand textile wastewater plants and adopt the best available technique for microplastic removal.
