“Tipco Asphalt Public Company Limited is very interested in future collaboration with MTEC. The company will help disseminate this collaborative achievement to other organizations and institutes, as well as publicize the competence of Thai researchers to provide sustainable solutions for industry.”

Managing Director

Tipco Asphalt Public Company Limited produces and distributes asphalt products for road construction and maintenance, which is essential to transportation within the country. Since its establishment 39 years ago, the company places a high priority on innovation and operational efficiency. The company provide customers high-quality products and services while maintaining social responsibility and fostering sustainable development.

Through the company’s mission “we are a globally preferred integrated asphalt and petroleum-related products company” and vision “we distribute 6 million tons of asphalt and petroleum products across 5 continents by 2020 in a sustainable and responsible manner.”

Mr. Chaiwat Srivalwat, Managing Director of Tipco Asphalt Public Company Limited, recounts that the company is the leading asphalt manufacturer in Thailand and Asia. It manufactures asphalt products in compliance with the government policy to promote natural rubber consumption. The product must comply with regulations of the Department of Highways. Since the asphalt for the road construction has to contain concentrated latex, it causes problems to manufacturing processes at temperatures of 140-160 °C during asphalt-additive blending. The emission of ammonia vapor has occurred during processing with strong repugnant odor. The manufacturer has invested in ammonia scrubbers to abate the vapor emitted so that its effects on the environment is minimized.

The problem has been provisionally solved by reducing production output. In addition, the ammonia emitted is highly corrosive, thus causing manufacturing equipment to prematurely wear out. These problems have never been effectively solved and the concentrated latex has been continuously consumed for asphalt production. The ultra-low ammonia product by MTEC was attractive but requires industrial production. Thus, MTEC research team has negotiated with the supplier of concentrated latex and transferred the know-how for ultra-low ammonia production. The supplier has received a 3-year contract to supply the ultra-low ammonia latex to Tipco Asphalt Public Company Limited.

Mr. Chaiwat mentioned the other benefits of ultra-low ammonia latex as follows:          

  1. The company can boost their purchasing capability for natural rubber latex with high fatty acid emission. Therefore, the rubber farmers are able to sell more field latex. The company can thus contribute to the government policy to promote local consumption of natural rubber.
  2. Ultra-low ammonia latex is not required to be kept for 21 days to achieve the desired mechanical stability time (MST). Therefore, it is ready to be sold without the need for storage.

The company has been certified Green Industry Level 3 (Green System) from the Ministry of Industry. In addition, the company has been awarded National Occupational Safety & Health Awards, indicating the recognition of its outstanding commitment to safety, health, working environment and social responsibility.

Mr. Chaiwat restates that Tipco Asphalt Public Company Limited is very interested in future collaboration with MTEC. The company will help disseminate this collaborative achievement to other organizations and institutes, as well as publicize the competence of Thai researchers to provide sustainable solutions for industry.
