How can landfills be made more sustainable?

What are Landfills?

Landfills are sites for the disposal of waste materials. They go by other names as trash dumps, tips, dumps, rubbish dumps, and garbage dumps. The most traditional and widely used method of disposing of trash is through landfills, even though daily, intermediate, and ultimate covers were first systematically buried with rubbish in the 1940s. They are essential for the correct disposal of solid waste because they keep communities clean, lessen the quantity of garbage that enters the environment, and aid in the prevention of disease transmission.

Among the well-known landfills in India are:

  • Bhalswa Landfill, Delhi: This landfill is located in northwest Delhi and towers 53 metres over the Bhalswa Resettlement Colony, Bhalswa Dairy, and Shraddhanand Colony. It has significantly impacted the surrounding areas, leading to pollution and health hazards.
  • Ghazipur Landfill, Delhi: One of the largest landfills in Delhi, it stands at 65 metres (213 feet) and has been a significant source of environmental and health concerns due to its size and the release of harmful gases and leachate. At Strata Global, we have had the opportunity to work on a solution engineered by involving a system using StrataGrid™ geogrids and StrataWeb® geocells. From capping the landfill to beautifying the space to minimise foul odours, our products have worked to improve the quality of life for locals.

  • Okhla Landfill, Delhi: This is another major landfill in Delhi that has been a cause of environmental and health issues due to the unscientific disposal of waste.
  • Deonar Landfill, Mumbai: This is the largest and oldest landfill in Mumbai, receiving a substantial amount of waste daily and causing pollution in its surrounding areas.
  • Kodungaiyur Landfill, Chennai: This landfill has been a significant concern due to its impact on the environment and the health of nearby communities.

Strata Global is operational worldwide. We have successfully completed Villena’s landfill Project. It included designing and delivering rainwater drainage systems and gas collection using Strata’s comprehensive StrataDrain™ drainage composite range and other geosynthetic products.

Today landfill management is a far more environmentally sensitive process through the use of the right materials to address the hazards of waste. Landfills can be sustainable, and waste management itself doesn’t have to be an unsolved problem. At Strata Global, we have partnered with local authorities to provide solutions which are at an early stage such as leachate management, mid-stage such as landfill expansion through vertical expansion or end-stage oriented applications such as landfill capping.

What happens when landfills are not dealt with properly?

When landfills are not dealt with properly, they can have serious detrimental effects on both the environment and human health. They discharge leachate, which can contaminate surrounding water supplies and worsen ecosystem degradation, and methane gas, a strong greenhouse gas that plays a major role in climate change. Depending on the kind of trash, they release additional harmful gases that pollute the air and affect the health of the residents around. In addition to releasing unpleasant odors, the breakdown of garbage in landfills can draw bugs. Even though the majority of landfills were built before people lived there, most of them are now located in densely populated urban areas. Landfills demand vast quantities of land space. Even though they pollute the surrounding area, poorly managed landfills have significant governance costs since they cause people to avoid the area, depreciate real estate values, negatively affect public opinion, and cause governance problems.

As part of our mission to provide environmentally friendly alternatives for civil engineering procedures, Strata Global has worked on cutting edge landfill projects, such as building the first vertical landfill in history in Vapi, Gujarat, India. The existing landfill site was in a congested zone, and in order to fulfil the demand for larger storage volume, new containment techniques and StrataGridTM geosynthetic material were used. For vertical landfill expansion projects, Strata Global uses geogrids, geocells, and reinforced soil structures as landfill construction options. Our knowledge and products are designed to offer effective and long-lasting solutions for land development and waste containment. We have participated in the development of contemporary landfills, like the one in Model City, New York, where high-pressure gas lines were circumvented using their techniques. These initiatives show Strata Global dedication to cutting-edge and environmentally friendly landfill building techniques.

What are geosynthetic landfills?

The use of geosynthetic materials in landfill construction and closure to improve stability, stop erosion, and manage environmental effects is known as a geosynthetic landfill. As barriers to liquids and gases, drainage paths, liner system protection, geosynthetics like drainage geocomposites, geomembranes, geogrids, and geotextiles are very useful. These components are essential to the design of landfills in order to regulate waste cover applications, control odours, and stop water infiltration. On the other hand, poor geosynthetic system design or construction can cause stability problems and, in the worst case, even landfill collapses.

Here, geosynthetics are essential to landfill design because they act as drainage systems to gather liquids and stop leaks, as well as liners to stop liquid migration. Sturdy barriers that prevent the spread of fluids, geomembrane liners require rigorous construction standards to prevent damage. By lowering hydrostatic stresses and effectively draining accumulated liquids, Strata Global’s geosynthetic drainage system-StrataDrainTM composites and StrataGridTM for veneer reinforcement, improves landfill stability without damaging the soil. Errors in lined landfills highlight how crucial it is to use appropriate design and construction techniques when using geosynthetic materials. They are an obvious solution for any business trying to enhance its waste management procedures because of these advantages.

Environmental benefits of using geosynthetic products in landfills:

The value of using geosynthetics are many for agencies seeking improved operations and updated solutions. Geosynthetic helps in-

  • Preventing contamination: Geomembranes in geosynthetic liners prevent leachate leakage, reducing the risk of groundwater contamination from waste. At Strata Global, we have also introduced a leak detection layer to ensure any compromise in the structure is immediately addressed.
  • Improving Durability and stability: Geosynthetics resist chemical degradation, ensuring long-term durability and stability under various environmental conditions.
  • Controlling odour and erosion: Geosynthetic covers control odours, prevent erosion, and offer design flexibility in landfill applications.
  • Reducing Environmental Impact: By reducing the need for natural materials and minimising disturbance to existing soil during installation, geosynthetics help lower the environmental impact of landfill construction and maintenance.

Landfills using geosynthetics not only enhance containment efficiency and cost-effectiveness but also contribute to environmental protection by reducing contamination risks, ensuring durability, and minimising environmental disturbances during construction and operation.

Strata Global offers innovative solutions for landfill construction, such as geosynthetic drainage composites like StrataDrain™, which works to improve landfill performance and maintenance efficiency. In the design of lined landfills, geosynthetic components are essential for creating liners to prevent vertical liquid migration and drainage fields to collect liquids and prevent leaks. Geomembrane liners act as stable barriers against liquid spread but require high construction standards to avoid damage.

Strata Global provides a range of geotechnical products and comprehensive solutions for various applications, including landfills, mining operations, railways, container yards, and commercial and residential development projects. Our products like StrataWeb® and StrataGrid™ offer cost-effective and sustainable solutions for soil reinforcement, erosion prevention, and waste containment in landfills and mining operations. By utilising geosynthetics effectively, landfills can be built taller, allowing for higher waste storage capacity within the same land area.
