Keresa Plantations Sdn Bhd

Keresa Plantations Sdn Bhd is a local bumiputra company with 22 years of experience in oil palm plantation. Currently, Keresa manages 8,551 hectares of oil palm plantation at Lavang Land District, Bintulu, Sarawak which started operation since 1996. Keresa Plantations Sdn Bhd wholly own subsidiary of Limar Group of Companies and has its headquarter in Kuching, Sarawak.

Keresa also provides direct processing service through the existing of Keresa Mill Sdn Bhd, a subsidiary of Rajang Wood Sdn. Bhd.. The mill started its operation in April 2007, boasting an area of 32.63 hectares, which comprises of mill proper, effluent ponds and water reservoir. Keresa Mill designed throughput is 45 metric tonnes per hour, which is expandable up to 60 metric tonnes per hour to escalate processing of daily oil palm production.

Since 11th November 2015, through hardwork and relentless effort, both Keresa Plantations Sdn Bhd and Keresa Mill Sdn. Bhd. was honorably certified with Malaysian Sustainability Palm Oil (MSPO) to offer concrete assurance to palm oil producers, importers and consumers in term of its credible sustainable value chain and origin starting from its production to consumption.

With the strive to excellence in its operations, Keresa became the first local Sarawak company to be certified with Roundtable Sustainable Palm Oil (RSPO) since 21st October 2010. In addition, Keresa also honoured with the International Sustainable Carbon Certification (ISCC) on 17th September 2012 for all its operations.

Vertical Sterilizer

This technology has been around for quite some time but its use has been limited to mills of small capacities of less than 10tph. It was only until recently that interest in this technology was revived, with Sime Darby Berhad building its Hadapan Mill in Johor and Perlis Plantation Berhad with its mill in Sampit, Indonesia.

Our adoption of this technology was based on the belief that the heat transfer between steam and the fresh fruit bunches is better in a vertical sterilizer, thereby improving the sterilization effect on the FFB. This is a key component in palm oil milling for optimal oil extraction. We were confident that the documented and well known problems associated with vertical sterilizers such as blockages at the fruit discharge outlets, oil loss in condensate and EFB due to compaction and throughput problems were surmountable through present day engineering solutions.

Our mill no longer required the normally extensive space for a marshalling station/yard with the associated rail tracks, transfer carriages, FFB cages, hydraulic winches, tippler, and elaborate conveying structures.

Kernel Extraction & Recovery

Our kernel extraction and recovery system is primarily based on the compact dry air separation system in particular for the:

  • Nut and fiber separation to separate the nuts from the fiber;
  • Destoner for stone removal; and
  • Crack mixture (CM) separation to separate the dirt and shell from the kernel

Our nut crackers are called Rolek Nutcrackers, manufactured by Hur Far Engineering with support and research back-up by MPOB. This particular type of nut cracker was chosen for its high cracking efficiency as part of our efforts to produce premium quality kernel for the local livestock feed industry.

The mixture of broken kernel together with dirt and shell from the CM outlet are separated using the combination of hydro-cyclone and claybath systems for the final recovery of kernel.

Oil Extraction & Recovery

In conventional mills hot water is added at the press to dilute the press liquor. Our oil extraction and recovery system requires some hot water dilution. However, the oily condensate produced from sterilization process is pumped to the crude oil gutter to the maximize oil recovery. This system essentially comprised two vibrating screens, a mini-clarifier, a sludge oil tank, a two stage de-sanding cyclone, a decanter, a pure oil tank and a centrifugal oil separator.

Where we are

Keresa’s existing plantation is located on the west of Lavang Land District and the nearest town to the plantation is Tubau.

Keresa Plantations is about one and half hours of driving or approximately 120 km from Bintulu.

From Bintulu drive through the Pan- Borneo highway and turn into Bintulu-Bakun Junction. Another 55km drives from the junction to reach Keresa Plantations main gate.

Our Journey Towards Sustainability

Keresa Plantations and Mill’s first steps towards sustainability was realized with the commitment of their senior management to be a member of the Roundtable for Sustainable palm Oil (RSPO). RSPO approved the company’s membership on 03 June 2009. This marks an important landmark for our company and sets a new vision for Keresa to be a responsible producer of crude palm oil.

Keresa has taken the first step in RSPO implementation in August 2008 by conducting a full independent review of our current operations against the RSPO Principles & Criteria. No land conflicts exist with local communities and the plantation was established from secondary jungle under a former rattan plantation. It is anticipated that Keresa will be ready to undergo its certification audit by 2010. It is hoped that our journey towards more responsible practices will provide a better environment for us to work and live in. Our work was recognised to meet the RSPO standards by independent auditors in October 2010 and today our certification scope includes our CPO Mill, Keresa Mill, and the supply base from both our own plantations and the neighboring indigenous smallholders. Our ambition is to demonstrate that our journey towards more responsible practices will provide a better environment for our people to work and live in.

Progress so far

Since December 2009, some of our biggest changes have been made with the development of new policies that will help us realize our goals towards sustainability. This has been our first step and the challenge now is to be able to make these policies implementable. The new policies we have introduced, or revised, include:
