The Group is involved in oil palm cultivation and milling. It cultivates its own oil palm plantations through its ownership of plantation land in Indonesia. In addition, the Group has two oil palm seed breeding and research centers that provide services to oil palm estates.

The combined Group has 20 operational mills. In FY2011, the Group’s oil palm plantations produced approximately 838 thousand MT of CPO, most of which were supplied to other subsidiaries of the Group mainly for the manufacture of edible oils & fats. By-products from the FFB milling process such as palm kernel which are not required for the Group’s refining needs are generally sold to external parties.

IndoAgri through its subsidiaries PT SIMP and PT PP London Sumatra Indonesia Tbk (Lonsum), is a member of the Roundtable on Sustainable Palm Oil (RSPO). IndoAgri believes its business operations are conducted in accordance with the RSPO's Principles and Criteria for Sustainable Palm Oil.

On 30th April, 2009, all of Lonsum's North Sumatra estates and factories as being producers of crude palm oil had been certified fully conforming to the RSPO's Principles & Criteria for sustainable palm oil production. The certificate from RSPO's independent accredited auditor, TÜV Nord, had been achieved through the two month audit in late 2008, which itself follows Lonsum four year journey to conformity.

In October 2011, we achieved RSPO certification for an additional 25,000 tonnes of CPO, bringing the Group’s total certified CPO production to approximately 195,000 tonnes (roughly 23% of the Group’s total CPO production in 2011).
