Development of energy consumption norms for ceramic industry of Vietnam

Abstract

Specific energy consumption (SEC) is calculated for many manufacturers, in a variety of industries, as a key energy efficiency indicator for process improvement and energy consumption control. The energy consumption norm is an SEC index that is regulated separately for each industry, as a reference value that manufacturers must adhere to. Vietnam has researched and published many regulations on energy consumption norms in industries such as the plastic industry, sugar industry, paper industry, steel industry, seafood processing industry, and beer and beverage production industry. This study aims to benchmark the specific energy consumption and energy consumption norm for the ceramic industry in Vietnam. We collected and analyzed information from 26 ceramic manufacturers across the country, represents approximately sixty percent of the total ceramic production. The results show that the average specific heat energy consumption is 1248.4 kcal/kg; the average specific electricity energy consumption is 145.3 kWh/ton. Combining the calculation results with the development orientations and policies of the Government, scenarios on Vietnam ceramic industry energy consumption norms have been given. The application of energy consumption norms can reduce about 10.7% of the total energy demand of the ceramic industry, but will also affect more than 50% of the current number of ceramic manufacturers. This will be an important tool for the Ministry of Construction to help Vietnam achieve energy-saving targets, sustainable development, and net zero emissions by 2050.
