Cleaning Up Communities With HDPE

Reductions in greenhouse gas emissions and odors were among benefits when a lagoon cover was replaced with High-Density Polyethylene (HDPE).

The project, next in the IGS Sustainability Case Study series, describes Fabtech Australia’s work in Shepparton, Australia, replacing a cover on a wastewater treatment basin to improve methane capture.

Positive gains included better methane harvesting for conversion into clean energy, reduced carbon footprint, and the creation of a more pleasant amenity for residents. You can read the full case history here.

Launched in March, the IGS Sustainability Case Study series highlights how geosynthetics offer a more sustainable solution in construction projects. Available as one-page pdfs, the profiles are easily downloaded and shareable.

Access the latest case study and more on the IGS Sustainability web page here, where you can also find more resources including eBooks, videos, and papers.
