Mission

Premier Research Unit in Developing and Supporting the Malaysian Processing Industry.

Vision

To develop the Malaysian rubber processing sector as a globally competitive and sustainable industry.

The Processing and Pollution Research Unit (PPRU) plays a central role in supporting and enhancing the midstream sector of natural rubber industry. The R&D activities of this unit cover four main aspects of the midstream sector namely raw rubber processing, development of specialty rubbers, environmental management and zero-discharge technology. The unit also offers effluent testing services by the Pollution Control Laboratory (SAMM ISO17025 accredited laboratory) and technical advisory services in the areas of rubber processing and effluent treatment.

Raw Rubber Processing

Research activities are being carried out to address current problems in raw rubber processing including low efficiency and labour intensive technology. Improved and novel processing techniques are being investigated to increase processing productivity and efficiency while simultaneously minimizing waste discharge and pollution to the environment. New techniques particularly in rubber drying and packing are being actively researched to enable automation in rubber processing.

Development of Specialty Rubbers

Malaysia is the pioneer for production of specialty rubbers for niche markets such as epoxidised natural rubber, ENR (Ekoprena) and deproteinised natural rubber, DPNR (Pureprena). Improvement for Pureprena and Ekoprena production lines are being carried out to increase process efficiency and productivity. Development of new process for Ekoprena production is one of the primary research activities in view of an increasing trend towards the use of Ekoprena in the production of green tyres.

Pollution Control

Main R&D activities in environmental management cover three major sources of pollution from rubber processing namely effluent, solid and air pollution. Active research activities to address and minimize pollution from rubber processing industry include development of effective and high performance effluent treatment systems, malodour characterisation and control as well as solid waste treatment and utilisation.

Effluent Treatment by a Submerged Aeration System

Malodour Control by a Water Scrubber System

Zero-Discharge Technology

In response to global trends towards sustainable development and green manufacturing, the unit embarks on R&D activities with the ultimate aim of transforming the raw rubber industry into a green industry with zero discharge. Alternative rubber processing technologies based on membrane separation techniques and bioprocessing are being investigated to improve rubber processing by minimising waste discharge and by enabling utilisation of processing by-products especially non-rubber components in NR latex for production of value-added products.

Pollution Control Laboratory (PCL)

The Pollution Control Laboratory (PCL) under Processing and Pollution Research Unit of the Malaysian Rubber Board (MRB) was established in 1978 initially to support R&D activities of the MRB in effluent treatment and management. Since 1998, PCL started to provides testing services for environmental samples from rrubber processing and palm oil mill effluent, sewage, industrial effluent and water, sludge and other solid wastes as well as air and gases to MRB and its clients in rubber and other related industries

Vision

To be a persistent organization in providing quality services and solutions in pollution area for the benefit of society and industry.

Mission

To provide clients the quality support services in handling their pollutions cases as required by the Department of Environment (DOE).

Objectives

To help the rubber industry in analyzing their effluent discharge with the minimal charges
To give industry the appropriate advice in handling their effluent and pollutants
To help the industry by carrying out studies on sludge management and water pollutions
To provide the industry of odour concentration measurement by olfactometer

Core activities

PCL is organised in a manner as to have independence and adequate resources, facilities as well as personnel, to properly discharge its functions to carry out testing activities in conformance with the requirements of Malaysian Standard MS ISO/IEC 17025:2005 and other associated SAMM documents. Table 1-3 summaries the testing provided by PCL.
Among the facilities available in PCL are pH meter, atomic absorption spectrophotometer (AAS), digestion blocks, distillation units, Ultra Violet (UV) spectrophotometer, Total Organic Carbon (TOC) Analyzer, gas chromatograph and gas chromatograph-mass spectrometer (GC-MS).
For air and gases testing, the laboratory has IQ 1000 gas analyzer for analysis of gases such as carbon dioxide, carbon monoxide, methane, ammonia and hydrogen sulphide, Fuji gas analyzer for analysis of carbon monoxide and Dynascent digital olfactometer for determination of odour concentration in air samples and of the products. At present, PCL is the only facility in Malaysia providing odour concentration determination by the Dynamic Olfactometer which complies with the newly introduced Malaysian Standard MS 1963:2007 Air Quality-Determination of odour concentration by using dynamic olfactometry.

PCL under Processing and Pollution Research Unit, also provides advisory and consultancy services in the area of environmental management for rubber processing and rubber product manufacturing industries such as solving the operational problems of wastewater treatment plants, designing wastewater treatment plants and in the testing of the important effluent parameters.

Advisory & Consultancy Services

The Pollution Control Laboratory provides services for environmental samples such as water, wastewater, sludge, air and gases to MRB and clients in rubber and other related industries. It was established in 1978 to support R & D activities of the MRB in effluent treatment and management.

The PCL is one of four MRB’s laboratories that are accredited to SAMM (ISO/IEC 17025:2005) and is fully equipped with facilities for testing of the following parameters in water, wastewater and sludge samples:

Pollution Control Laboratory in Sungai Buloh

Alkalinity
Ammoniacal nitrogen
Biochemical Oxygen Demand (BOD)
Chemical Oxygen Demand (COD)
Metallic elements
Nitrate
Nitrite
Oil & grease
Organic nitrogen
pH
Phosphorous
Solids
Sulphide
Total Nitrogen
Total Organic Carbon (TOC)
Volatile Fatty Acids

Among the facilities available are atomic absorption spectrophotometer (AAS), Ultra Violet (UV) spectrophotometer, Total Organic Carbon (TOC) Analyzer, gas chromatograph and gas chromatograph-mass spectrometer (GC-MS).

COD Test

Testing of Air and Gas Samples

For air and gases testing, the laboratory has IQ 1000 gas analyzer for analysis of gases such as carbon dioxide, carbon monoxide, methane, ammonia and hydrogen sulphide, Fuji gas analyzer for analysis of carbon monoxide and Dynascent digital olfactometer for determination of odour concentration in air samples and of the products. At present, PCL is the only laboratory in Malaysia that provides odour concentration determination by olfactometer.

Advisory and Consultancy Services

The Processing and Pollution Research Unit provides advisory and consultancy services in the area of environmental management for rubber processing and rubber product manufacturing industries such as solving the operational problems of wastewater treatment plants, designing wastewater treatment plants and in the testing of the above mentioned parameters.
