Today is June 9, 2026, and in Altamonte Springs, Florida, something pretty remarkable is happening. The city is embracing a game-changing technology called hydrothermal liquefaction (HTL) to transform sewage sludge into usable energy and clean water. This isn’t just any run-of-the-mill recycling project; it’s a bold move to tackle some serious environmental issues, including the notorious “forever chemicals” known as PFAS.
PFAS are widely found in waste and are making headlines for all the wrong reasons. These chemicals have a reputation for their extreme durability and their potential health risks. In Altamonte Springs, however, the HTL process is stepping in to reduce PFAS levels in biosolids by about 96%! That’s some impressive progress. Jim Oyler, the President and co-founder of Genifuel Corp., explains that HTL involves a hot, moist process where organic waste is converted into oil and gas. And guess what? The oil and gas produced can be refined into energy sources such as diesel, jet fuel, or biodiesel.
Turning Waste into Resources
The water generated by HTL is not just a byproduct; it’s clear, clean, and sterilized, making it suitable for industrial use. This is particularly crucial as Altamonte Springs has already been working on a pilot project called pureALTA, which treats wastewater to drinking water standards. It’s a two-for-one deal, really—reducing waste and creating valuable resources.
This innovative project was backed by a hefty $750,000 grant from the Innovative Wastewater Technologies Grant Program of the Florida Department of Environmental Protection (FDEP). It’s one of five projects funded through this program, with three others also kicking off in Central Florida. The preliminary results are encouraging, and a final project report is expected this fall. How cool is that?
But let’s circle back to the bigger picture. As Central Florida continues to grow, the challenges related to wastewater disposal will only intensify. HTL technology offers an alternative approach to managing biosolids, which are often used as fertilizers but can lead to harmful nutrient overloads in agricultural areas. By converting these biosolids into energy, the city is turning a potential problem into a solution.
The Bigger PFAS Picture
While Altamonte Springs is making strides, it’s essential to understand that the regulation of PFAS is still a bit of a patchwork. Some PFAS compounds have been banned or restricted, but many remain unregulated. Long-chain compounds like PFOS and PFOA have been outlawed since 2010, 2020, and 2022 under the Stockholm Convention—except for a few specific uses. Authorities are increasingly aware of the health risks associated with PFAS, and there’s ongoing collaboration among countries like Germany, Denmark, the Netherlands, Norway, and Sweden to limit these substances in the EU. The goal is to use PFAS only where absolutely necessary, which is a tall order given their widespread presence.
In Altamonte Springs, the HTL project represents a proactive response to these growing concerns. By tackling PFAS head-on, the city is not only addressing local waste management issues but also contributing to the broader fight against pollution. And with FDEP planning to launch an online dashboard to share information about this project and others, transparency is part of the game too. It’s an exciting time for environmental innovation in Florida!
