 Perma-Fix Environmental Services NASDAQ:PESI Inc has announced that its second-quarter 2022 revenue rose 20.5 to 19.5 million, boosted by sequential and year-over-year sales growth in both its Treatment and Services segments. The nuclear services company said growth in both segments was due, in part, to the resumption of work and attaining complete operational levels on several projects that had been delayed due to the impact of the coronavirus COVID-19 pandemic, as well as a 54 increase in waste receipts, including both commercial and international waste.
