Geomembrane for Waste Management
-Landfill liner
durable and Highly resistant landfill HDPE liners have a primary function to create a low permeability barrier, which act as one of the essential lines of defence in protecting the groundwater. The groundwater is in potential danger of becoming contaminated from landfill leachate (which is liquid that migrates through the landfill); either from precipitation, or from that liquid already present in the waste. Both used in Municipal solid waste landfill and hazardous waste landfill.
-Landfill Capping/Cover
Landfill capping prevent rain and rainwater runoff entering the landfill which would increase the amount of leachate that has to be treated and disposed. in addition, landfill capping helps to collect and remove landfill gas (LFG) from the landfill. flexible LLDPE geomembranes limit seepage of rainwater into the landfill and are well suited to accommodate the strains and resulting stresses that arise from differential settlements of the waste. LLDPE Geomembrane landfill caps serve multiple functions including containment of landfill gas (methane), minimizing odours generated by decomposition of the waste and preventing infiltration of rainwater increasing volumes of leachate. Generally, they are covered with soil and grass to protect the geomembrane and form an attractive landscape.
-Animal and Bio wastes
Animal agriculture is important to global food, nutrition, and economic security. Animals are raised primarily for food and non-food purposes such as companions, leather and even manure in some production systems. Some potential wastes generated during animal production operations include waste or left-over feed, wastewater, hatchery wastes, abattoir wastes and manure. Anaerobic digestion of manure produce energy, mainly biogas. geomembranes are used to solve animal waste containment problem and helps in storage and reuse of methane gas.
Geomembrane for Mining Applications
-Heap Leach Pads
Geomembranes helps in the performance of mining facilities where they are used for containment of process solutions, particularly in heap leach pads. Heap leaching is a mineral processing technology whereby large piles of crushed or 'run-of-mine rock' (or occasionally mill tailings) are leached with acidic chemical solutions that extract valuable minerals.
-Tailing Dams
geomembrane can be used in Tailings dams and ponds to prevent the release of concentrated mine chemicals into the environment and to improve consolidation of the tailings. Solution ponds with Geomembranes helps retain mining chemicals and process water for retention, reuse, ortreatment. These ponds and dams accumulate the solids remaining from the mining operation, often in the form of a fine sand. Tailings ponds with liner allow the sand to settle and the liquid to separate for reuse.
-Liner for Salt Evaporation Ponds
Geomembranes Can be used to line salt evaporation ponds in warmer climates and even in harsh environments which are durable and offer excellent chemical resistance to salts, which is important because of the long-term exposure of the geomembranes to the brine.
-Caps and Closures
LLDPE geomembrane is good choices when the design criteria include high multiaxial strains in capping and closure of mines. geomembrane cover facilitate deformation caused by differential settlement without failure of the containment.
-Gypsum and potash stacking
Phosphogypsum stack system can create immediate and substantial hazard to human health, safety, or welfare, and to the environment by the chemicals, pollutants and hazardous substances, geomembrane can be used for the lining of phosphogypsum reservoirs for the placement of dredge material, also lining the reservoir used for storing contaminated process water.

1. How long does an HDPE liner typically last?
An HDPE liner can last for up to 50 years or more, depending on the application and environmental factors.
2. What is the installation process for an HDPE liner?
The installation process for an HDPE liner typically involves excavating the area where the liner will be installed, laying down a layer of geotextile fabric, and then placing the HDPE liner on top. The edges of the liner are then anchored to prevent movement.
3. Can an HDPE liner be used for potable water storage?
While HDPE liners are commonly used for storing water, they are not typically used for potable (drinking) water storage. Specialized liners are required for potable water storage to ensure that the water remains safe to drink.
4. What is the cost of an HDPE liner?
The cost of an HDPE liner varies depending on its thickness, size, and other factors. However, HDPE liners are generally considered a cost-effective option compared to other types of liners.
5. What are the specifications for HDPE geomembrane used in gold mining heap leaching liner?
The specifications for HDPE geomembrane used in gold mining heap leaching liner vary depending on the specific application, but typically include thickness, permeability, and chemical resistance.
