Energy Conservation Measure

Since 2013, all diesel fuel steam generators have been suspended in our largest factory in Xinhui, China, and replaced by renewable fuel for steam generators. Solar energy panels have been installed in Xinhui plant and Hong Kong Tai Po plant to provide energy for water heating effectively. All factories and warehouses are installed with large windows to utilise natural sunlight and reduce energy use of lighting. All hot water pipes and steam pipes are insulated to minimise heat loss.

In 2014, Lee Kum Kee has become the first condiment enterprise in China to invest in photovoltaic power generation project, installing it on the rooftops of four warehouses totalling approximately 47,000 square metres in the Xinhui production base. The semi-conductor boards convert light energy directly into electricity, thereby reduce coal combustion and thus the emission of carbon dioxide and sulphur dioxide, contributing to the conservation of resources and the environment

In 2015, as a large scale renewable energy system, Geothermal Heat Pump, began operation in Xinhui plant, Lee Kum Kee prides itself as the first enterprise in the world to adopt geothermal energy in soy sauce production. With underground pipe network over 218,000 meters long over an area of 113,500 square metres, the system utilises geothermal energy from the ground to accommodate heating and cooling processes of soy sauce production, with an estimated annual saving of 6,000 MWh energy usage and 21,115 tonnes of water consumption in heating, ventilation and air conditioning.


All plants utilise natural sunlight and reduce unnecessary energy usage. Xinhui plant has utilised the Biomass completely in production.

Sealed water pipe network pumps water underground for heat absorption or emission to save water consumption in heating, ventilation and air conditioning.
