SAR-ALAM Indah Sdn Bhd, a subsidiary of Weida (M) Bhd, has signed a RM15mil contract with Danish waste management firm Niras Consulting Engineers & Planners A/s to undertake the integration of a sludge digester or biogas plant facilities into the Matang septic sludge treatment plant in Kuching.
Sar-Alam Indah is managing the RM16.8mil Matang septic sludge treatment plant that is owned by state-owned Sarawak Inc Sdn Bhd.
The plant treats sludge from some 65,000 septic tanks in Kuching.
A memorandum of understanding (MOU) for the biogas plant project was signed in Kuching yesterday.
The signatories were Sar-Alam chairman Datuk Dr Stalin Hardin and Niras top executive Heanng Laudreson.
Sarawak Environment and Public Health Minister Datuk William Mawan Ikom and Danish Ambassador to Malaysia Lasse Reimann witnessed the ceremony.
There are 20 similar biogas plants in Denmark.
According to Sar-Alam, the project was expected to be completed in two years.
Upon completion, the biogas plant, the first in Sarawak, would be able to improve the treatment of the septic sludge, and provide treatment of new wastes like oil and grease from restaurants and eateries, organic waste from abattoirs and food processing factories as well as livestock manures, the company said.
According to Sar-Alam, the Matang treatment plant has the capacity to treat up fo 18,000 cu m of sludge a year.
The state government has made it a must for all septic tanks to be desludged from Jan 1.
This is to prevent the discharge of the sludge into the Sarawak River, which provides the city's drinking water.
