1. Why should building a landfill be?
According to the Word bank report, Global garbage waste volume will increase by 70% by 2050, Because of the’s world rapid urbanization and population growth, annual global waste generation is expected to increase to 3.4 billion tons over the next 30 years, up from 2.01 billion tons in 2016, the report found.
High-income countries account for only 16% of the world’s population but generate more than one-third (34%) of the world’s total waste. The East Asia Pacific region produces a quarter (23%) of the world’s total waste. By 2050, sub-Saharan Africa is expected to generate more than three times the amount of waste from current levels, while South Asia is expected to double the amount.
Plastics are particularly problematic, the report noted. If not collected and managed, plastic can pollute and affect waterways and ecosystems for hundreds of thousands of years. In 2016, the world generated 242 million tons of plastic waste, accounting for 12% of the total solid waste.
The How Much Waste 2.0 report highlights that solid waste management is a critical, yet often overlooked, element of sustainable, healthy, and inclusive cities and communities. A third of waste in high-income countries is recycled through recycling and composting, compared with only 4% in low-income countries.
Depending on how much waste is generated, its composition, and how it is managed, it is estimated that 1.6 billion tonnes of carbon dioxide equal were generated in 2016 from waste treatment and disposal, accounting for about 5% of global emissions.
The report states that good waste management is essential to building a circular economy. In a circular economy, products are designed and optimized for recovery and recycling. As national and local governments embrace the idea of a circular economy, waste management is becoming a smart and sustainable way to help foster efficient economic growth while reducing damages to the environment.
Supporting countries to make important decisions on solid waste management financing, policy and planning are key. Solutions include:
Provide funding to build advanced solid waste management systems in countries most in need, especially the fastest-growing ones.
Assist major waste-producing countries to reduce plastic consumption and marine litter through comprehensive waste reduction and recycling programs.
Reduce food waste through consumer education, organics management, and coordinated food waste management programs.
Since 2000, the World Bank has claimed more than $4.7 billion and more than 340 solid waste management programs in countries all over the world.
Building a landfill project is an essential and right way for us to dispose of garbage and protect the environment. Landfill geomembrane is new designed anti-seepage material for landfill projects and it is used more and more.
Geomembrane is an ideal material for landfill liner
Geomembrane is a kind of designed anti-seepage material for landfill project programs. HDPE Geomembranes have the following advantages, such as high strength, good anti-seepage performance, strong anti-corrosion, anti-aging ability, and convenient construction. The reliability application is good. HDPE geomembrane is a kind of geomembrane, it is an ideal material for landfill liner, it is made of high-density polyethylene virgin resin and other additives such as carbon black, antioxidant, ultraviolet absorber, thermal stabilizer, which makes HDPE has the following advantages :
Good impermeability;
Corrosion resistance to most chemical substances;
Good mechanical and welding characteristics;
Good working characteristics at low temperature;
Can be made into various thicknesses;
Not easy to age with a long service time which can be up to 70 years.
Thus, it is used in the anti-seepage treatment of landfills. HDPE film has two kinds of the rough surface and smooth surface. The rough surface is used for slope surface to increase stability and prevent landslides. The smooth surface is used at the bottom of the landfill, which is cheap and applicable. The textured surface is used at the slope of the landfill project.
2. Landfill Geomembranes Thickness Selection
HDPE Geomembrane produced by Earth Shield, the Landfill Geomembranes thickness can be from 0.2~3.0mm. Different thickness has different applications.
