BEFORE the pandemic, GDP growth rates in the developing world were always higher than in developed economies.And because developing economies had much lower levels of petrochemicals consumption than their rich counterparts, it meant that the multiples over GDP were higher than in the rich word, where consumption was pretty much saturated.
For instance, polyethylene (PE) demand in a developed country such as Germany might have grown at 0.3% times GDP whereas in Indonesia the growth could have been one or more times higher than the rate of growth in GDP.But as The Economist wrote in this 11 July article: “In 2021 the poorest countries, which are desperately short of vaccines, are forecast to grow more slowly than rich countries for only the third time in 25 years.”
Might the multiples over GDP growth also be adversely affected in the developing world, trending lower than the historic norms?
They will almost certainly remain higher than the rich countries. But here is the thing: as millions more people are pushed back into extreme poverty by the pandemic or are denied the opportunity to achieve middle-income status, I believe that developing-world multiples may well decline.Escaping extreme poverty means being able to, say, afford a whole bottle of shampoo for the first time rather than a single-serve sachet, thereby raising per capita polymers consumption.

An enzyme-mimicking catalyst opens a new route to important organic molecules such as glycolic acid and amino acids from pyruvate, report researchers in Japan. Moreover, the new catalyst is cheaper, more stable, safer and more environmentally friendly than conventional metal catalysts used in industry, they note, adding that it also displays the high enantioselectivity required by the pharmaceutical industry.
“On top of these advantages, our newly developed organic catalyst system also promotes reactions using pyruvate that aren’t easily achievable using metal catalysts,” says Santanu Mondal, a PhD candidate in the chemistry and chemical bioengineering unit at Okinawa Institute of Science and Technology (OIST) Graduate University, Okinawa, Japan, and lead author of a study recently published in Organic Letters.
“Organic catalysts, in particular, are set to revolutionize the industry and make chemistry more sustainable,” he stresses.
The researchers use an acid and an amine mixture to force the pyruvate to act as an electron donor rather than its usual role as an electron receiver (Figure 1).
Effectively mimicking how enzymes work, the amine binds to the pyruvate to make an intermediate molecule. The organic acid then covers up part of the intermediate molecule while leaving another part that can donate electrons free to react to form a new product.
Currently, the organic catalyst system only works when reacting pyruvate with a specific class of organic molecule called cyclic imines.
So, the researchers now are looking to develop a more-universal catalyst, i.e., one that can speed up reactions between pyruvate and a broad range of organic molecules.
The challenge here is to try to make the electron-donating intermediate stage of pyruvate react with other functional groups such as aldehydes and ketones. However, different catalysts create different intermediates, all with different properties. For example, the enamine intermediate created by the researchers’ new reaction only reacts with cyclic imines. Their hypothesis, currently being investigated, is that creation of other intermediates such as an enolate, if possible, would achieve a broader pyruvate reactivity.
In terms of cost, the researchers note that a palladium catalyst used in similar reactions is 25 times more expensive than their organic acid — which also is made from eco-friendly quinine.
In addition, they believe scale-up of the process for industrial use definitely is possible. However, the researchers caution that the current amine-to-acid-catalyst loading ratio of 1:2 probably would need to be optimized for better results at a larger scale.

SEE THE END section of this blog post for a dystopian version of our environmental future. In a follow-up post – which I will publish on Thursday, 1 July – I will offer some suggestions about how we can avoid an outcome that nobody of course wants.Both posts are meant to be provocative, challenging and controversial because only through debate, and sometimes outright argument, will we get to the answers.
If you disagree after either or both posts have been published, great, that would be good. In fact, I would love to hear from you whatever your views at john.richardson@icis.com. The petrochemicals industry can do this; we can fix this if we create the right forums for ideas and then solutions.
Let me provide the background first. Let me start by examining developments in the refinery industry and the implications for petrochemicals as important background. Then I will look at a sample of ICIS petrochemicals demand growth forecasts for 2020-2040. I will conclude by providing the bleakest of bleak outcomes for the world in 2025

Petrochemicals themselves remain in short supply. This is partly because of reduced feedstock from refineries, a consequence of the pandemic-related collapse in transportation fuels demand.Global petrochemical supply is still edging back to something like normal following the US winter storms in February, during which most US capacity was shut down.
A point of discussion is whether containers will become available in the right places at the right prices to relieve tightness in the European polyethylene (PE) market, once US supply has normalised. The container issue is making it difficult to move PE and polypropylene (PP) cargoes from Asia to Europe.Market intelligence from the US-based ICIS CDI team indicates that enough container freight space will be available to resume significant shipments of US PE to Europe, albeit at high prices. It will be several more weeks before domestic pipelines have been refilled, enabling US producers to refocus on exports, added CDI.
