HDPE Landfill Liner Systems for Solid Waste Containment in Bangladesh

Landfill liner systems are the ideal geotechnical products applied for landfilling solid waste, rubbish garbage among mountains, excavated mines, etc. Landfill liner systems are generally composed of HDPE geomembrane liner and woven geotextile or other geosynthetic products. Due to their excellent corrosion resistance and acid and alkali resistance, HDPE Geomembrane liner and non-woven geotextile can resist more than 80 kinds of highly corrosive chemicals, and have strong tensile properties, UV resistance, anti-aging capabilities, etc.  Geotextiles and HDPE Geomembrane liner are widely used geotechnical materials in waste dumps and landfills.

With the fast economic development, urban modernization and vigorously promoting the industrialization process, it has brought huge economic benefits, and at the same time caused a large amount of industrial liquids and hazardous wastes in the industry, causing serious damage to the surrounding soil and ecological environment. Residual industrial liquids and hazardous wastes are extremely corrosive and need to be properly treated. Most countries are paying more and more attention to the ecological environment, and the national environmental awareness is gradually improving. Some domestic waste landfills and industrial factories produce residual hazardous waste landfill treatment projects in people’s field of vision, landfill liner systems, non woven geotextile and other geosynthetic materials are widely used in landfill treatment. These geosynthetic materials are made of non-toxic and environmentally-friendly raw materials.

The traditional reinforced concrete lining anti-seepage layer is complicated in construction, labor-intensive, time-consuming, and the construction cost is very high. Geotechnical materials have the advantages of low cost, convenient transportation, short construction period and simple construction. According to the statistics of the authoritative geotechnical materials association, it can save 50% of the cost and play an irreplaceable role. The landfill liner systems is the most important part of the whole project, and the non-woven geotextile plays a very important role as the protective layer and the permeable filter layer of the anti-seepage liner. In the single-layer anti-seepage layer, two layers of non-woven fabric are generally used as a protective layer to sandwich the HDPE geomembrane liner. The cloth protects the lower layer of water and the large particles adhere to the cloth to form a filter layer, allowing only fine soil particles. And water filtration, to prevent the loss of the lower layer of soil to maintain the stability of the soil layer, to avoid the occurrence of uneven settlement, thereby protecting the safety of the entire project of the landfill, while the geotextile prevents the upper layer of pollutant leachate and the underlying soil. Direct contact has played a role in isolation.

The landfill liner systems are powerful and efficient system to contain tons of solid waste garbage. Therefore, the HDPE geomembrane liner is 1.5mm and the width should be greater than 6 meters to reduce the welded joint. As practice has shown that 70% of the leakage from landfills occurs in welded joints. The selection of geomembrane is very important for environmental protection. The geotextile liner is 600g filament geotextile to protect HDPE geomembrane from damage, HDPE geomembrane in the buried area is acts as a special impermeable liner.

Landfill Liner System for Waste Containment in India

Landfill liner system is highly engineered containment systems, designed to minimize the impact of solid waste (refuse, trash, and garbage) on the environment and human health. BPM HDPE plastic liner has excellent impermeability, elongation, conformity and weld abilities which can offer stable steep slope lining and strong protection to avoid leakage, stress cracking for waste contamination. The primary purpose of the landfill liner system is to isolate the landfill contents from the environment and, therefore, to protect the soil and ground water from pollution originating in the landfill. The greatest threat to ground water posed by modern landfills is leachate. Leachate consists of water and water soluble compounds in the refuse that accumulate as water moves through the landfill. This water may be from rainfall or from the waste itself. Leachate may migrate from the landfill and contaminate soil and ground water, thus presenting a risk to human and environmental health.

Landfill liner system is designed and constructed to create a barrier between the waste and the environment and to drain the leachate to collection and treatment facilities. This is done to prevent the uncontrolled release of leachate into the environment. Society produces many different solid wastes that pose different threats to the environment and to community health. Different disposal sites are available for these different types of waste. The potential threat posed by the waste determines the type of liner system required for each type of landfill. Liners may be described as single (also referred to as simple), composite, or double liners.
Our customer from India had a landfill liner system project for waste containment. The landfill site covers 30,000 square meters. The pond liner fabric project management includes personnel, equipment, material entry and field process test. After negotiation, we
