With the signing of the contract to deliver two PF1800 Kompogas steel digesters to German Bio Energy Technology (GBE) for the biogas plant project in the Chinese city of Chongqing, Swiss clean-tech company Hitachi Zosen Inova (HZI) has successfully entered the Chinese market. Located in Sichuan Province and covering an area of 82,400km2, with a population of just under 30 million Chongqing is said to be the largest city in the world.

For HZI and its local partner GBE, the plant in Chongqing is their first joint project. “In China, the composition of mixed city waste is often unpredictable, which calls for a certain degree of solid technological experience in this field,” explains Markus Dicke, CEO of German Bio Energy Technology. “Kompogas technology is the only one which can prove to fit this requirement, promising optimal biogas production. The decision to choose technology leader HZI was therefore taken at an early stage,” he added.

The biogas plant will be constructed at a local waste disposal site, where the deliveries of household waste will first be sorted. The two digesters will then process up to 200 tonnes of the separated organic fraction every day, producing around 6.7 million Nm3/a of biogas and compost.
