Zero Liquid Discharge (ZLD) technology is to pretreat and evaporate industrial wastewater, collect the condensed water distilled from the zero liquid discharge system for water recycling applications, and send unevaporated solids to landfills or use them as valuable salt. Class by-products are reused. In 2018, the global ZLD market demand was approximately 5,442 million U.S. dollars, with the largest industrial application being the energy and power industries, followed by the petrochemical and chemical industries.
In recent years, the world has been affected by extreme climates, and the supply of water services has begun to face major changes and tests, causing the world to face more serious water shortage problems. The fierce competition for water resources comes from the fact that the earth will face a 40% water shortage from 2030.
In response to the COVID-19 epidemic, various countries have issued a series of bans, city closures and traffic restrictions, driving the demand for housing, working at home, online shopping, and home entertainment. This in turn has driven the demand for 3C products such as information and communications products. Among these, display panels have shown one of the greatest increases in demand, and the global display screen equipment market grew by 19% in 2020, reaching USD 13.52 billion.
In 2018, the global audio and video equipment market was valued at approximately US$160.4 billion. It has declined at a compound annual growth rate (CAGR) of -1.86% since 2014. It is expected to decline slightly at a compound annual growth rate (CAGR) of -0.05% until 2022 of US$160.1 billion.
Transportation is the main artery of the city. A well-functioning transportation system must be closely linked with the three major elements of "people, vehicles, and roads." In order to optimize traffic efficiency and optimize the energy use and mobility efficiency of cities, countries have introduced smart mechanisms in recent years.
The United States, the European Union, and China are the world’s three largest economies, which together are estimated to account for 60.92% of the global economy in 2021.
South Korea is a country lacking natural resources. Its economic development is export-oriented, and its industrial structure is dominated by heavy chemical industries. The five major industries, including automobiles, shipbuilding, semiconductors, steel, and smartphones, earn a lot of foreign exchange for the country's economic growth.
The United Nations Industrial Development Agency (UNIDO) announced the July 2020 World Manufacturing Competitiveness Index (CIP) which is based on 2018 indicators. South Korea ranks third after Germany and China among 152 countries in the world. CIP is a composite index of 8 items including per capita manufacturing, value-added, and manufacturing export value. It reflects the overall competitiveness of the manufacturing industry in each country. UNIDO publishes the CIP every other year.
Although the share of manufacturing in Japan's GDP has declined in the past few decades, Japan still has a very large manufacturing base. In addition, Japanese manufacturers have extensive global connections, especially in Southeast Asia, many of which have substantial operations in countries such as Thailand.
There are many reasons for manufacturers to move their offshore or near-shore production bases to Mexico. The advantage of cheap labor is one of the most prominent.
