The Cleanup Artists: Zefiro Methane, 374Water, Befesa, and the Multi-Billion-Dollar Market for Contaminated Sites

Burning faucets, contaminated groundwater, toxic dust from steel furnaces - industry leaves behind contaminated sites that conventional disposal solutions are powerless to address. Three companies have identified a market niche precisely in this area. Zefiro Methane plugs millions of abandoned wells in the US, 374Water eliminates "forever chemicals," and Befesa turns the toxic filter dust from the steel industry into usable zinc. The logic behind all three business models is the same: the more severe the environmental damage, the larger the market and strict regulation becomes a revenue driver here, rather than a risk factor as in other industries.
