EPA to test new cleanup method for former chemical plant

The agency has directed $30,000 in grant money to study the possible use of activated charcoal as a way to remove concentrations of the chemical DDT in flood plain soil, the Morning Sun reported. DDT and other volatile organic chemicals, such as polybrominated biphenyls, were left behind at the site when the plant closed roughly 40 years ago. DDT seeped into the soil and was also found to have leaked into the nearby Pine River, costing more than $100 million to clean up. The first phase of the site cleanup was completed last fall, and the second phase is underway. Workers will be inserting metal rods into the ground to remove chemicals from the soil. The rods bring the chemicals to boiling, and then they're siphoned off and destroyed. The pilot study will spread activated charcoal over soil contaminated with DDT to test whether the chemical binds to carbon. The chemical would then remain in the soil but it would no longer be bioavailable to be taken up by organisms. The land currently lacks soil creatures and insects, while robins that have chosen to nest in the area show uncharacteristic behaviors, according to Jane Keon, secretary of the Pine River Superfund Citizens Task Force. The group is an EPA-sanctioned community group that's been overseeing cleanup of the Superfund site.

Southeast polyolefins demand growth could be negative again in 2021

Article | July 13, 2021

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.

Energy portfolio restructuring: Charting the future

Article | June 17, 2021

Consumer needs and preferences in the energy industry are evolving. Environmental, social and governance (ESG) concerns are becoming more acute—inspiring action and shifting value towards low-carbon solutions. These trends accelerated in 2020 and for the first time, market capitalization of leading low-carbon solutions companies began to overtake those of oil and gas (O&G) majors. This is despite the majors laying out energy transition strategies, setting low carbon energy targets and generating higher revenues by an order of magnitude.1 In response to this radically changing landscape, energy companies are charting divergent courses for their futures. Some continue to bet on their ability to generate returns from the O&G value chain. They are focusing on growing margins and lowering carbon intensity. Others are supplementing their capabilities with low-carbon energy solutions or exiting hydrocarbons altogether. This blog focuses on the path forward for the energy majors in Europe who are betting big on diversification.
