Can Plastics Be Turned Into Oil?

January 15, 2019 | 47 views

The world has a plastic problem. Too much of the material is ending up in our environment, and recently microplastics were even found in humans for the first time. There’s a growing movement to curtail our use of the material, but what should we do with what we already have? According to Let’s Recycle, there are a growing number of companies exploring the possibility of recycling plastics into oil.

Organic Catalyst Boasts Big Benefits

Article | June 11, 2021

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.

Transporting biological and chemical materials - what you need to know

Article | June 6, 2022

The landscape of biological and chemical logistics has changed rapidly - as have the regulatory frameworks around it. What has not necessarily kept pace is the end-user understanding of the nature of these logistical processes, their opportunities and their constraints. Twenty years ago, the transmission of biological and chemical materials was limited to a small range of organisations: usually national and international research companies, hospitals, major university departments, police and military departments with forensic responsibilities.

Setting record straight on testing harm in chemicals

Article | June 15, 2021

The modern world is built on chemicals, be it the medicines we use, or cleaning fluids, crop protection products, or the raw materials for everything from laptops and mobile phones to clothes and furniture. Across all, we have created an entire modern society with chemicals, and, as a result, constantly stretched the size of the world population we can feed, clothe and shelter. Yet, balancing all the gains from the modern chemistry around us against any negative environmental and human impact has been a rising concern, making for ever greater focus on testing and on risk assessment.

Why chemical characterization is the best way to assess patient risk

Article | February 11, 2020

Everyone is very familiar with the phrase when buying a house: All that really matters are three things - location, location, and location. This same principle applies to extractables and leachables chemistry analysis – the three things that truly matter are identification, identification, and identification. The greatest growth in the past ten years in demonstrating the safety of medical devices and container closure systems for drugs has been using analytical chemistry to determine what chemicals can leach from the device and what the patient is exposed to during its intended use.

Tampa fire rescue working to clean up after chemical spill

Tampa | February 20, 2019

Tampa Fire Rescue officials responded to a hazmat situation Wednesday morning on Columbus Drive. According to a press release, a tanker trunk was transferring a cleaning chemical to another storage tank, which caused a chemical reaction and spill from the top of the holding tank. Residents next to the complex were moved to another place while crews cleaned up the spill, and the leak was stopped by 9:20 a.m. The shelter order was lifted, and residents were allowed back shortly thereafter. Two workers were seen at the hospital for observation following the spill, but there were no reported injuries. Crews are working to neutralize and clean up the chemicals, and there is currently no threat to the surrounding area or public, fire rescue officials say.

A catalyst for ‘greener’ hydrogen production

The Chemical Engineer | January 14, 2019

A RESEARCHER at the University of Delaware (UD), US has patented a process that could enable greener production of hydrogen. The process uses electricity and a copper-titanium (Cu-Ti) catalyst to make hydrogen from water. Hydrogen is an energy carrier and can be used to power fuel cells in vehicles, buildings, and other infrastructure. It can also be used to upcycle biomass, such as straw and grasses, into high-value chemicals to produce a range of products, such as plastics, paint, and personal care items. However, using hydrogen for these purposes is challenged by the unsustainable methods required for hydrogen production. Currently, the main processes for production use fossil fuels and produce carbon dioxide.

NGOs demand release of REACH studies submitted as confidential under TSCA

Chemical Watch | December 20, 2018

A coalition of NGOs has filed a public records request demanding the release of REACH studies submitted to the US EPA under TSCA that are being withheld as confidential. And the NGO action could represent an early test to the EPA's interpretation of what types of information can be protected as CBI under the law. At issue is the first of ten draft risk evaluations issued under the reformed TSCA, which focuses on pigment violet 29. Released to some controversy last month, the draft proposes to conclude that the substance does not pose an unreasonable risk to human health or the environment.
