respectively. In March, Bayer CEO Bill Anderson raised the specter of another eventual breakup that would create separate pharmaceutical and crop protection companies. “Not now—and this
mixtures by immersion in a decontami- nation solution, disassembly, testing and decontamination of floor materials, crushing of reinforced concrete, concrete and brick materials, thermal neutralization of debris, process- ing of used decontamination solutions, and disposal of solid waste at a landfill....
5.2 Incineration of process wastewater–waste-to-energy option Incineration is the most common (almost exclusive) treatment of PWWs, which is an accepted method for disposal. In many cases, the water content of the initial process wastewater is really high. In this case, it is advisable to ...
Residuals (disposal of sludge generated (solid waste) and CO2emissions into the atmosphere, a product of mineralization through sequential processes). The sludge generated in the primary process (CF) was considered hazardous waste. In this stage, more than 95% of the AB194 dye was removed from ...
The reclaimer is then shut in and dumped to a waste disposal. Therefore, the impurities are removed, but the MEA bonded to the salts is also lost. For DEA systems, a reclaimer is not required because the reactions with COS and CS2 are reversed in the stripper. The small amount of ...
In the mid-1980s, Dow Chemical, then one of the world’s largest chemical companies, was in the midst of a public advertising campaign designed to enhance its corporate image. Dow had been through a rough patch of bad press and corporate troubles stretching from the mid-1960s through the ...
In fact, it is a side production with a cost for disposal. Its valorization is often limited to thermal incineration. There are various attempts for alternative valorization methodologies to create a waste biorefinery [37, 38], but reuse is limited to very specific type of biomass waste. For ...
A first global inventory of radioactive waste disposal at sea was issued in 1991 by the International Atomic Energy Agency (IAEA) and subsequently updated in 1999 and 2015. This report provides data on the date and location of the disposal operations as well as the type, number and weight or...
And because most of the largest chemical companies operate globally, the Global Top 50 is also a good check on the health of the industry. For 2023, the fiscal year on which the survey is based, the diagnosis is that the world’s chemical sector experienced a downturn. ...
Processes for adsorption of CO2 from air at room temperature have recently been studied using silica-supported amines [49,50], which can be regenerated with low-cost waste heat such as steam. Nevertheless, amine-based systems have the limitations of toxicity, volatilization, and oxidative ...
