How much electricity can one grab of household waste generate? At Nanshan Energy Ecological Park in Shenzhen, south China's Guangdong Province, a single grab weighing several tonnes can generate around 3,000 kWh of electricity. With a designed daily processing capacity of 2,300 tonnes, the waste-to-energy plant manages to turn household rubbish into a valuable energy resource. Before incineration, waste is fermented for five to seven days to reduce moisture and improve combustion efficiency. Beyond its waste-to-energy operations, the park also features a recycling art gallery and a sky-high coffee bar overlooking the sea, bringing together environmental innovation and public leisure under the concept of building a factory while creating a park.
