The United States Environmental Protection Agency unveiled on Monday proposals to implement more stringent nitrous oxide emissions limits on heavy-duty trucks beginning with model year 2027 vehicles. The proposals would encourage use of new emissions control technologies – rather than a switch to electric vehicles – and would also require trucks to comply with the standards for longer distances and periods of time.

Heritage-Crystal Clean’s oil business segment – including oil collection and rerefining activities and sales of recycled fuel oil – recorded increases in revenue and operating margin for the fourth quarter and full fiscal year. The company, which is based in Elgin, Illinois, cited an increase in base oil prices as the driving factor for the improvement.

The South American country’s output of base oil – primarily consisting of API Group I oils – declined to 44,000 metric tons in January, down from 46,000 tons in the same month last year and 21% lower than 56,000 tons in January 2020, according to data released by the National Agency of Petroleum, Natural Gas and Biofuels. Sequentially, January’s production this year was up 2% from December last year.
