Hill Garden Tea factory, then a non-operative plant, was acquired by the Evergreen group in 1990 and gradually guided it to the present successful status during last two decades. At present, Hill Garden runs a 90,000 MT of made tea production per month with 5M green leaf capacity per day. This success was achieved through an almost full conversion of the factory machinery acquiring modern technology and the use of 5S management practices. Today, the rolling room is converted into a full automated status where the factory was able to reduce the labour cost while ensuring the high quality of the production.

Hill Garden is also famous for the payment of a competitive price for green leaf which in turn facilitated the high quality of green leaf standards. Also, the factory has employed a well-qualified group of extension officers to look after a continuous supply of good quality green leaf through a personalized extension service.

Similar to all other Evergreen member, Hill Garden also maintains high profile relationships with both of its green leaf suppliers and staff through customer support scheme and a staff welfare scheme.

Hill Garden has also stepped into various environmental protection and other social responsibility activities. This includes a newly built bio-gas unit which runs on the waste of the factory and then the gas generated uses back for the factory needs.
