Safe containment solutions with geothermal energy in Costa Rica
March 17th, 2025
Contributed by SOTRAFA In 2024, SOTRAFA supplied ALVATECH geomembranes for the Borinquen geothermal project in Costa Rica. This project uses heat from volcanic areas to generate clean, renewable energy. The process includes digging wells, extracting hot water, generating electricity, and reinjecting the cooled water into the subsoil. This method protects the environment and reduces dependence […]

What does ‘weathering of geomembranes’ mean?
November 7th, 2024
By Felon Wilson The term “weathering” on first glance appears to be straightforward. Most in the geomembrane industry consider it to narrowly describe sunlight or UV resistance only. In fact, testing and property specifications are often only from a sunlight exposure standpoint. But the effects of changing temperatures, precipitation, wind, etc. can be factors of […]
Navigating unexpected contaminants with your geomembrane system
March 5th, 2024
By Felon Wilson Geomembranes are long-term containment barriers. As such, it is not uncommon for them to be called upon to contain liquids not originally planned. That is particularly true in applications which are more likely to produce changing or varying liquid containment requirements. This blog series will dig into how unexpected contaminants can be […]

By coincidence, two independent surveys were recently released which identified key issues in the U.S. water industry. The reports are listed in Table 1. Table 1 While both reports address respondents’ perceptions of current and anticipated market […]
How geomembranes help improve water quality, lower costs and increase efficiencies in wastewater treatment – Part 4
December 20th, 2023
By Felon Wilson “While the environment is a very emotional and even moral issue for most of us, to be effective in the area, as one practitioner put it, you need a good engineer, not a poet.” - James W. Conrad, Counsel, American Chemistry Council In the final segment of our look at geomembrane uses in […]
How geomembranes help to improve water quality, lower costs and increase efficiencies in wastewater treatment – Part 3
December 11th, 2023
By Felon Wilson “Old ideas are being evaluated and new concepts are being formulated.” George Tchobanoglous, University of California Davis, in Wastewater Engineering: Treatment, Disposal and Reuse, 3rd Edition. In this post and the next, geomembrane use in wastewater management will be discussed. The wastewater management system will be broken into two parts: Wastewater Collection and […]
How geomembranes help to improve water quality, lower costs and increase efficiencies in wastewater treatment – Part 2
November 30th, 2023
“We forget that the water cycle and the life cycle are one.” Jacques Yves Cousteau In Part 1: Wastewater Industry in North America,” a brief history of the efforts to deal with wastewater was explored along with estimates of the size of the industry itself. In this post, we will take a look at the current […]
The rise of BGMs: A decade of transformation in the geomembrane industry
November 13th, 2023
A decade ago, bituminous geomembranes (BGMs) were a relatively unknown player in the landfill and mining industries. Fast forward to the present day, and BGMs have emerged as a significant disruptor, posing a formidable challenge to traditional high-density polyethylene (HDPE) geomembrane manufacturers. The industry landscape has shifted dramatically, with BGMs steadily gaining market share and […]

November 8th, 2023
By Felon Wilson Part 1: Wastewater Industry in North America “We still think of air as free. But clean air is not free, and neither is clean water. The price tag on pollution control is high. Through our years of past carelessness, we incurred a debt to nature, and now that debt is being called.”– […]
