By Hermann Ng, Senior Technical Sales Manager, APAC FIGURE 1 Photograph courtesy of Solmax Biogas production from anaerobic waste stabilization ponds, typically used for treatment of wastewater from farms and industry, is a smart, sustainable, eco-responsible option. A key component of these systems is the geosynthetic material used for the sealing system. Why are polyethylene geomembranes a better choice and how do you select the right material? [...]
CSPE-lined Palos Verde Reservoir in Los Angeles County, Calif. Photograph courtesy of Raven Engineered Films Most polymeric liners undergo oxidative aging immediately after installation, and this continues over time, ultimately leading to a reduction of their molecular chain length (this destructive process is referred to as oxidative degradation). In particular, high-density polyethylene (HDPE), linear low-density [...]
Photograph courtesy of Solmax Tibet has an average elevation of more than 13,100 feet (4,000 m), reaching to 16,400 feet (5,000 m). At these heights, temperatures can remain below freezing all day in winter, plunging to –4°F (–20 °C). In 2018, Tibet’s first large solar thermal district heating system was designed and built at 15,000 [...]
There is more to shopping for a landfill cover than just selecting materials. While it is important to select a material capable of handling the UV rays and rough surfaces of a landfill cell, it is also a good idea to consider what the manufacturer of the cover can offer beyond just the right polymers.
