Assessment of the feed additive consisting of propionic acid for all terrestrial animal species for the renewal of its authorisation (Eastman Chemical B.V., Perstorp AB, Dow Europe GmbH, BASF SE).

Propionic acid is currently authorised as a technological additive (functional group: silage additives) for all animal species. The applicants requested for the renewal of the authorisation of propionic acid when used as a feed additive for all terrestrial animal species. The applicants have provided evidence that the additive in the market complies with the conditions of the authorisation. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP Panel) confirms that the use of propionic acid under the current authorised conditions of use is safe for the target species, the consumers and the environment. Regarding user safety, the additive is corrosive to the skin and any exposure to users is considered a risk. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.

An industrial case study on the combined identification and offset-free control of a chemical process

For three decades, model predictive control (MPC) has been the flagship advanced control method in the chemical process industries. However, most implementations still use heuristic methods for designing MPC estimators, especially for offset-free MPC implementations. In this paper, we present a recently developed maximum likelihood-based method for the identification of linear augmented disturbance models for use in offset-free MPC. This method provides noise covariances that are used to derive Kalman filters and moving horizon estimators, forgoing the need for manual design and tuning of the estimator. The method is extended to handle closed-loop plant data. The proposed identification method and estimator design are evaluated in industrial-scale, real-world case study of a process at Eastman Chemical’s Kingsport plant. Using this identified model, we reduced the mean stage cost by 38% compared to the performance of the existing, hand-tuned MPC model.

LyondellBasell is getting green bonds

LyondellBasell Industries is launching a public offering of green bonds. The principal of the bonds will be $500 million and will bear a 5.625% interest rate. The proceeds from the bonds will go toward circular economy, renewable energy, pollution prevention, and energy efficiency projects. Green bonds have become popular as a way to connect chemical companies with investors interested in backing sustainability. In March, Air Products raised more than $1.3 billion in two bond offerings that it intends to use for low-carbon ammonia and sustainable aviation fuels, and Eastman Chemical closed a $500 million green bond offering.

EPA proposes to allow chlormequat on food

US grain producers may soon have a new tool to help improve crop yields in the face of increasingly severe weather events related to climate change. Against the wishes of environmental groups, the US Environmental Protection Agency is proposing to allow outdoor use of the plant growth regulator chlormequat chloride on barley, oat, triticale, and wheat. Taminco US, a subsidiary of Eastman Chemical, petitioned the EPA to allow such uses in 2021. Regulators did not find any risks of concern to human health, including to infants and children, but they did identify risks to workers who handle the pesticide and to some wildlife. Chlormequat is currently allowed on ornamentals in greenhouses and nurseries in the US. The chemical blocks hormones that stimulate growth, resulting in shorter and thicker stems that are less prone to breaking and bending. Earlier this year, the Environmental Working Group (EWG) sounded the alarm after finding

Portfolio Design Based on Bigdata Analysis and Sharpe Ratio Optimal model

Sharpe ratio is a classic index that can comprehensively consider both return and risk. At the same time, it is only used to investigate the asset of the final venture capital portfolio. Therefore, Sharpe ratio is an important research topic in the financial field. This paper is based on big data analysis and minimum variance model. Thereinto, the companies selected in these five industries are AVIC Electrical Systems Co., Ltd., Archer Daniels Midland Company, Bank of America Corporation, Eastman Chemical Company and China XD Plastics Company Limited. Sharpe ratio is a representation of unit risk and return on investment. The greater the Sharpe ratio, the higher the unit risk return of this portfolio. Secondly, the data we use comes from Yahoo Finance, in which we select the year from 2015 to 2021, because the data of these seven years are more accurate. Meanwhile, the tool we use is RStudio, because RStudio is very excellent in graphics and charts. According to the analysis, these results indicate that one can find the portfolio with the highest risk return rate in these seven years. These results shed light on portfolio design based on bigdata analysis in terms of optimal approaches.

Framework for selecting carbon emission abatement projects in supply chains

ABSTRACT This article addresses the challenges for companies that seek to invest in carbon abatement projects. Traditionally, such companies would address their own operations, but it might be more efficient to invest in improving the operations of a supplier or customer. By adopting a supply chain perspective on carbon abatement projects, this study proposes a way to account for activities beyond the company’s boundaries. First, the proposed decision-support framework enables companies to define the appropriate boundaries for carbon emission measurement and abatement and identify the relevant optimisation problem. Second, this framework describes options for optimising the level of abatement effort linked to each selected action. Third, an application of the framework to the Eastman Chemical Company reveals several real-world implications, including recommendations for where to exert carbon abatement efforts in a supply chain. As this illustrative case shows, external abatement efforts can be worthwhile in practice.

FDA approves the Pfizer-BioNTech COVID-19 vaccine

The US Food and Drug Administration gave its full approval to the Pfizer-BioNTech COVID-19 vaccine on Aug. 23, making it the first COVID-19 vaccine to be licensed by the US government. The vaccine will be sold as Comirnaty and is approved for people 16 and older. Almost immediately, some companies, including Chevron, instituted vaccine mandates for some workers. And in advance of the Pfizer approval, many biotech and drug companies had implemented corporate vaccine requirements. But other companies, such as Dow, Eastman Chemical, and LyondellBasell Industries, are balking at requiring employees to be vaccinated, suggesting that the Pfizer approval will incentivize employees to get the shots. Eastman told C&EN that it has started a voluntary vaccine verification program, allowing people who have been inoculated to display their status with stickers to wear on their hats and helmets. Dow says it has been providing vaccines to its employees. At sites where

Green Chemistry : Challenges and Opportunities

Green chemistry has now been around for two decades, and it has been making a real difference in our world. The well-known companies and organizations that have embraced the discipline include Nike, BASF, Hewlett-Packard, the National Aeronautics & Space Administration, Eastman Chemical, United Soybean Board, Pfizer, the Environmental Protection Agency, Bayer Material Science, Codexis, Johnson & Johnson, Amgen, DuPont, and World Wildlife Fund. The global market for green chemistry is predicted to grow exponentially in the coming years, to $98.5 billion by 2020. The young discipline has produced thousands of scientific papers. Research networks in more than 30 countries on every settled continent have been formed along with at least four new international scientific journals. Green chemistry has been credited for decreasing the amount of chemical waste released to the air, water, and land. It has also spawned new areas of research including green solvents, bio-based transformations and materials, alternative energy science, molecular self-assembly, next-generation catalyst design, and molecular design for reduced hazard. Some industry reports predict green chemistry as the future of all chemistry
