Thailand's largest petrochemical producer PTT Global Chemical (PTTGC) is planning to invest up to $25bn to achieve net-zero greenhouse gas (GHG) emissions by 2050.
PTTGC expects its peak GHG production to reach 9mn t in 2025, without giving details of current levels. The company is spending $1.3bn to improve efficiency in order to reduce emissions by 20pc by 2030 and gradually towards net-zero by 2050, said Kongrapan Intarajang, chief executive officer of PTTGC, in an interview with Argus.
Steps to be taken include adopting cleaner fuels in the future such as hydrogen, utilising digitalisation to reduce feedstock consumption and investing in new technology.
Intarajang said the company has recently decided that there will be no further outright investments to build new basic petrochemical plants or refineries, and PTTGC will be looking to increase efficiency by de-bottlenecking its existing plants, increasing feedstock flexibility and reducing costs in order to enhance its current production. "We are not going to build, in Thailand, another one million tonnes of these kind of products," said Intarajang.
PTTGC is currently converting 52-53pc of its feedstock crude to chemicals at its Map Ta Phut complex. Depending on fuel demand, the company might possibly increase the conversion rates to improve efficiency on a need basis in future.
The company is also looking to adjust its portfolio by investing in building more recycling plants. PTTGC is constructing a new polyethylene and polyethylene terephthalate (PET) recycling plant in Map Ta Phut, and is targeting start-up by end of 2021. The plant in Map Ta Phut will consume 60,000 t/yr of high-density polyethylene and PET as feedstock and will produce 45,000 t/yr of recycled material. It firm also aims to increase the plant's capacity to 75,000 t/yr by 2025 in either chemical or mechanical recycling.
PTTGC currently has a joint venture with US-based biopolymer producer NatureWorks, with a 150,000 t/yr polyactic acid (PLA) plant in the US. The company has also committed to build a new 75,000 t/yr PLA plant in Thailand which is now in the engineering phase and is expected to come on line in 2024.
The capital expenditure for portfolio adjustment strategy is estimated to be $22bn in the next 30 years, which will account for another 25pc worth of carbon reduction. PTTGC aims to have 35pc of its portfolio focusing on performance and specialty chemicals by 2030 through mergers and acquisition. The current percentage of specialty chemicals in its portfolio is about 20pc and the company is looking to acquire more US- and Europe-based biochemical companies, particularly in the coating, high-performance and composite areas for now, to fill the gap.
"We go from the bigger picture, what businesses we want to dive in, and we narrow down to a few companies that we are interested in, and we start to approach and see whether it is feasible or possible. And we will continue to do the same", said Intarajang.
The remaining 55pc of GHG reduction will come from reforestation and new carbon capturing technologies. PTTGC is allocating $1.7bn to this area. The company has invested in venture capital in the US, Europe and China in clean technology start-ups which PTTGC hopes will pave the way to its net-zero ambition by 2050.
