Protection from microbes gives plastic products a longer life

Plastics, like other materials, are constantly exposed to the environment where they are located and, depending on the surrounding conditions, a broad array of microbes can exist on their surfaces, said Sustainableplastics.

This can potentially lead to a range of problems, from unpleasant odours to deterioration, that affect the sustainability of both virgin and recycled plastics in products. Whatever the industry, incorporating built-in antimicrobial additives into plastics to help reduce the growth of microorganisms and odours is one way to offer long-lasting product protection and sustainability.

Plastics are everywhere in our lives and, due to their versatility, have replaced steel in cars, paper in packaging, and wood in furniture. Its revolutionary discovery has led to the development of diverse, flexible and cost-effective materials that have influenced fashion and style, and made previously unattainable products available to all, from everyday necessities to once-in-a-lifetime luxuries. The demand for plastics is therefore continuing to skyrocket. However, single-use, disposable plastics have a long, none too complimentary history, with a bad reputation for posing environmental threats, from being pervasive in landfills and causing toxic pollution, to contributing to global warming and natural resource depletion.

Consequently, pressures from governments and consumers to offer more environmentally friendly plastic solutions are forcing a rise in demand for more durable, reusable or recyclable plastic products that result in less waste. However, plastic surfaces can sometimes succumb to the build-up of bacteria, moulds and mildew, leaving unpleasant odours and an unattractive appearance. This problem is exacerbated by reusing plastics that may already have been affected by microorganisms, for example, in storage containers, bottles and packaging used for products such as food, drinks and cosmetics. If these surfaces are not properly washed and disinfected, substances such as food debris or shampoo can collect in cracks and hard-to-clean corners, creating a nutrient-rich source for microbes. It is an issue that is prevalent in many sectors where manufacturers employ recycled plastics in their products, from toys and shower or hospital curtains to interiors and exteriors in buildings, automobiles and planes, in a move towards sustainability.

We remind, Technip Energies and Agilyx announced today the launch of the TruStyrenyx™ brand, the only all-in-one solution for the chemical recycling of polystyrene. TruStyrenyx™ combines Agilyx’s pyrolysis process and Technip Energies purification technology, yielding a recycled styrene monomer with exceptional high purity. Styrene monomer is used to make numerous plastics and other polymers. It is one of the three primary components of ABS (acrylonitrile-butadiene-styrene), can make the pure polymer polystyrene, and is an ingredient in various synthetic rubbers.

Leaders from Braskem and Shell Catalysts & Technologies (SC&T) met at Shell’s research center in Amsterdam recently to participate in a technical exchange, said Hydrocarbonprocessing.

During the meeting, SC&T and Braskem agreed to extend their 15-year relationship for an additional five years. SC&T provides technical support and works with Braskem to improve operational performance and maintenance.

“We appreciate the long-standing relationship between SC&T and Braskem,” said Aloisio Souza Azevedo, global process manager for Braskem. “Shell is a key partner to Braskem and this relationship has brought us safety and added value to our operations. We look forward to continuing this relationship for the next five years and to our efforts to explore areas of collaboration and navigate together our transformation agenda."

Braskem and SC&T have been working to define a transformation map of initiatives in order to reach targets for operational excellence and decarbonization. A new technical services agreement will continue to help strengthen facility processes and maintenance.

“We are thrilled and humbled to announce that Braskem and SC&T agreed to build upon their strong relationship with an extended agreement,” said Diego Esposito, SC&T sales director for Latin America. “This is result of the fruitful 15 year relationship based on trust, collaboration and learning from each other. SC&T is committed to continue partnering with Braskem and to working together with them on their energy transition agenda."

As per MRC, Shell said it had to cut output at its German Rhineland refining facility, which makes fuels, heating oil and petrochemicals, citing low Rhine levels that have made the transport of goods via the river more challenging. "Due to the low Rhine water level we have reduced the capacity of Shell Energy and Chemicals Park Rhineland. The situation regarding supply is challenging but carefully managed," the company said in an e-mailed statement. The company did not say to what level capacity of the site which can process up to 17 MMt of crude oil a year, or 345,000 bpd, had been cut.

China's Sinopec Corp said on Monday it has put into operation the country's largest carbon capture, utilisation and storage (CCUS) facility in east China, and plans to build two more plants of similar size by 2025, said Reuters.

The state oil giant is one of the leading companies building pilot CCUS projects in China, part of the country's goal to reach peak carbon emissions by 2030.

The new CCUS project, which started construction just over a year ago, involves capturing carbon dioxide produced from Sinopec's Qilu refinery in eastern Shandong province during a hydrogen-making process, and then injecting it into 73 oil wells in the nearby Shengli oilfield.

Sinopec has estimated that 10.68 MMt of carbon dioxide will be injected into the oilfield over the next 15 years, boosting crude oil production by nearly 3 MMt.

Currently the CO2 from the Qilu refinery is transported by trucks to the oilfield, but Sinopec expects to complete a pipeline by the end of the year to move the CO2, which will be the first of its kind in China.

"While China's CCUS remains at an experimental stage, it's on a par with the levels of global peers, although lagging in some key technological know-how," Sinopec said in a press release.

Sinopec will explore setting up a CCUS research and development center by 2025, focusing on developing frontier technologies such as combining CCUS with wind and solar power, CCUS with hydrogen energy and biomass, the company said.

Last year Sinopec captured and stored more than 1.52 MMt of carbon dioxide. It aims to build another two pilot projects over the next few years in nearby Huadong and Jiangsu oilfields.

We remind, Sinopec and PetroChina -- two of the world's biggest energy firms -- will apply for "voluntary delisting" of their American depositary shares, the companies said in separate statements. The Aluminum Corporation of China, also known as Chalco, as well as China Life Insurance and a Shanghai-based Sinopec subsidiary.

According to our latest Drilling Productivity Report, the EIA estimates that crude oil production in the Eagle Ford region in southern Texas will average 1.2 MMbpd during September 2022, said Hydrocarbonprocessing.

Despite recent increases, less crude oil is being produced in the Eagle Ford region than before the pandemic—1.4 MMbpd in April 2020—and much less than the all-time high of 1.7 MMbpd in March 2015.

Because prices increased, we estimate that economically recoverable oil resources (the amount of recoverable oil that producers believe can be profitably produced) in the Eagle Ford formation, increased to 8.4 billion barrels in the first half of 2022, an increase from 0.5 B barrels in 2020. Between 2020 and the first half of 2022, crude oil prices more than doubled, according to our analysis, incentivizing future development in previously marginal areas.

This analysis of the Eagle Ford formation focuses on proved reserves and economically recoverable resources. Proved reserves are volumes of crude oil and natural gas that data demonstrate with reasonable certainty can be recoverable in future years from known reservoirs, considering existing economic and operating conditions. In contrast, economically recoverable resources vary considerably depending on price and cost assumptions. Economically recoverable resources represent a less certain estimate of future crude oil and natural gas volumes and production.

If prices are too low to provide a return on the investment of developing the well, producers will not invest in drilling the well. The Eagle Ford formation produces both crude oil and natural gas, so profitability is not only based on past crude oil or natural gas production rates but also on producers’ forecasts of future prices for natural gas and crude oil.

We remind, UK imported no crude oil or refined products from Russia in June for the first time on record, according to UK trade data, following phased sanctions on imports of Russian oil over the invasion of Ukraine. As a result of the UK's phase-out of Russian oil and gas imports, there were no flows of refined oil, crude, gas or coal, coke and briquettes from Russia in June, the Office for National Statistics said. The UK government said early March the country would phase out Russian oil imports by the end of 2022 and end imports of Russian liquefied natural gas "as soon as possible" thereafter.

Tosoh Corp. has unveiled a Yen200 billion (EUR1.47 billion) investment plan to expand production capacity and improving earnings during the 2023-2025 period, said European-rubber-journal.

Under the medium-term business plan, Tosah will increase output of a range of products, including polychloroprene rubber, flame retardants and other additives in rubber production. Tosoh manufactures chloroprene rubber at its site in Nanyo, Japan.

In 2019, the Japanese supplier started a two-year debottlenecking project to raise capacity of the plant by 3 kilotonnes per annum (ktpa) to 37ktpa. The chemical group's business plan announcement, issued 10 Aug, did not provide details on the size of the capacity expansions.

Under the medium-term programme, Tosoh aims to increase its operating income to Yen150 billion by 2025, from the Yen144 billion forecast for 2022. The company also expects sales to increase from an estimated Yen890 billion this year to Yen1,160 billion by 2025.

As MRC informed earlier, Tosoh Corporation, a major Japanese petrochemical producer, has announced it will permanently stop producing and selling toluene diisocyanate (TDI) and TDI-related products from its Nanyo complex in Japan, effective April 2023. Despite the continuous implementation of measures to improve profitability, the environment surrounding this business has become increasingly severe in recent years, and there are no prospects for improvement, the company stated. Tosoh currently produce 25,000 t/y of TDI at the site.

As MRC reported earlier, Tosoh resumed normal production at its caustic soda plant in Nanyo City (Nanyo, Yamaguchi Prefecture, Japan) with the capacity of 1.188 million tons of caustic soda and 1.06 million tons of chlorine per year on June 24, 2021. The company experienced some technical issues when restarting after a scheduled repair. Since June 12, the caustic and chlorine production capacity utilisation was reduced by about 30%.

Founded in 1935, Japan's Tosoh Corporation, headquartered in Tokyo, is an international chemicals and specialty materials company. The main activity of the company is the production of chlor-alkali and petrochemical products, which include ethylene, propylene, polypropylene, polyethylene and synthetic rubbers. The Tosoh Group globally includes over 130 companies with manufacturing facilities and offices in Japan, China, the Philippines, Indonesia, Singapore, Taiwan, South Korea, Germany, Belgium, Holland, Italy, UK, Greece, Switzerland and the USA.
