By finding ways to reduce the carbon associated with some of the main products that we make, we are advancing low carbon in our own operations while helping our customers meet their carbon goals for the products and services they provide.
We invented2 a process for purifying terephthalic acid more than 50 years ago, and today it is a key ingredient for making recyclable PET bottles for water and soft drinks. PTA is also used extensively in manufacturing clothing, home textiles, carpets and industrial fibre products.
Through our research and development efforts, we introduced a latest generation PTA technology in our Zhuhai, China facility that delivers 65% fewer GHG emissions, 75% less water discharge and 95% less solid waste disposal in its manufacturing process than the manufacturing process for conventional PTA technology of the 1990s.3
This latest technology was also retrofitted into our production facilities in Geel, Belgium and Cooper River in South Carolina, in the United States. Our new technology has resulted in improvements to energy efficiency in these facilities. It has allowed us to offer a unique new product range that includes world-class PTA technology and BP Target Neutral’s carbon offsetting expertise.
In support of our wider sustainability agenda, we launched a new low carbon PTA4: PTAir in 2016, offering our customers in the polyester value chain the opportunity to purchase a lower carbon feedstock. A feature of PTAir is its use of proprietary PX and PTA technology which supports a 29% lower global warming potential than the average European PTA production,5 which has been independently assured. BP customers can also go further in advancing their low carbon objectives by accessing the additional benefits of PTAir Neutral and PTAir Neutral Products.
We have also launched PTAir Neutral, the world’s first certified carbon neutral PTA.6 PTAir Neutral offers customers the opportunity to purchase a carbon neutral product with net zero carbon emissions. This is accomplished through BP Target Neutral, which invests in various carbon emission reduction projects which are located around the world. These programs provide economic, social and environmental benefits to the communities they serve.
BP customers also have the opportunity to offset their entire product carbon footprint – over and above their PTA use – to achieve full carbon neutrality across their product portfolio. This unique offer is made possible through BP’s non-profit division, BP Target Neutral.
PTAir is available in Europe, the United States and China today.
