Solid waste management
In recent years, solid waste management has arisen as a major environmental challenge. Because of the tremendous development in industry and population, the amount of garbage created around the world is staggering. Discarded wastes when not treated properly cause clogging and more complex challenges for humankind. Thus effective implementation of solid waste management plays a crucial role, but what exactly is it?
Solid waste management refers to the process where wastes are collected and segregated into different categories. Then the process ends with waste treatments in plants to make them fit for proper disposal. Let’s learn more about the subject through this article.
Why is it necessary to practice Solid Waste Management techniques?
To minimise the devastating effect it can have on the ecosystem and to avoid the depletion of natural resources, it is important to effectively practice solid waste management. It protects the following:
- Environmental protection: When the disposal of waste is treated well it avoids soil and water contamination. It prevents the release of harmful greenhouse gases and reduces the environmental impact of waste.
- Public health: Public health and waste management go hand in hand. Improper disposal can cause a heap of garbage untreated which can become a breeding ground for rodents and can cause life-threatening diseases and environmental pollution.
- Resource conservation: Solid waste management helps to reduce carbon footprints and treats the usage of harmful chemicals. It ensures a safer and cleaner future for generations to come.
What are the most common types of solid waste?
Solid wastes can be classified into different categories to understand what exactly falls where and how they can be treated effectively. The most common types are the following:
- Municipal solid waste: These are the everyday item wastes that are generated from households, working places, and common public spaces like discarded goods, and food waste.
- Industrial waste: The word “industrial waste” refers to unprocessed wastes that are disposed of by manufacturing and other sorts of businesses. These leftovers include chemicals, machine parts, and metal scraps.
- Construction & demolition waste: Waste generated in the form of cement, debris, concrete, etc during civil engineering activities is called C&D waste.
- Agricultural waste: This is the kind of waste usually generated due to farming and agricultural activities. It includes agro-products and livestock wastes.
- Hazardous waste: Due to rapid industrialisation and the growth of health sectors, toxic and chemical substances are getting dumped in the open which are considered hazardous wastes.
What are the different ways of solid waste management?
Many innovative techniques and procedures for managing solid waste have emerged as a result of technical growth and innovation, including:
- Landfilling: Landfilling management is the technique of using contemporary landfills to capture methane and other hazardous emissions. This technology is not present in every landfill, and landfills that are older or poorly constructed may harm the ecosystem over time. Its goal is to lessen waste’s negative environmental effects. Systems including gas capture, leachate collection systems, and liners are used in modern landfills to reduce their negative environmental effects.
Strata Global faced a significant challenge to extend the land life of a landfill reaching full capacity. The currently operating landfill site by Vapi Green Enviro Limited (VGEL) required a solution to serve for the next two years without any horizontal expansion due to limited area and high costs. To deal with this challenge, Strata devised a special containment system by using a reinforced soil structure that was able to support the vertical expansion of the landfill. In addition to safety precautions, the challenge also was to optimise the use of available limited space at the site. The waste was placed in individual cells that were filled successively. Strata’s solution employed our proprietary systems, the StrataSlope™ and StrataBlock™ systems, to provide a structurally sound yet aesthetically appealing structure while preventing leachate collection into the surrounding environment.
This effectively increased landfill capacity by 2.5 times compared to conventional methods and proved to be a very cost-effective and sustainable solution for the management of solid waste. Strata’s innovative techniques not only fulfil the immediate storage needs but also set a role model for future landfills, showing the integration of advanced engineering solutions in waste management practices.
Strata Global faced a major challenge when tasked with extending the lifespan of a landfill site that was nearing capacity. The existing landfill, operated by Vapi Green Enviro Limited (VGEL), required a solution to accommodate an additional two years of waste without the option for horizontal expansion due to space constraints and high costs.
In response, Strata devised an innovative containment system utilizing a reinforced soil structure, allowing for vertical expansion. This approach not only maximized the available space but also adhered to safety standards. The landfill was organized into designated cells, with each cell being filled sequentially. Strata’s method involved the use of their proprietary technologies, StrataSlope™ and StrataBlock™, which provided a robust and aesthetically pleasing structure while preventing leachate from contaminating the surrounding environment.
This solution effectively increased the landfill’s capacity by 2.5 times compared to conventional methods, demonstrating a cost-effective and sustainable approach to solid waste management. Strata’s innovative techniques not only addressed the immediate storage needs but also set a precedent for future landfill designs, emphasizing the importance of integrating advanced engineering solutions in waste management practices.
- Composting: Organic material breaks down and decomposes into nutrient-rich components through the process of composting.
- Recycling: Converting waste into reusable items to minimize and save energy and resources is known as recycling.
- Waste to Energy: With the growing energy demand, converting waste into heat or electricity with the method of incineration, pyrolysis, and gasification is referred to as waste to energy method.
- Waste reduction: It is the process of using fewer resources to minimise waste and prevent trash from being produced.
What are the main obstacles to solid waste management?
- Absence of infrastructure: The systematic collection, sorting, and disposal of garbage is a part of solid waste management. Most developing nations still do not have the necessary infrastructure to complete the procedure.
- General knowledge: Wastes are inappropriately disposed of and left untreated because of a lack of public understanding about waste management and suitable disposal practices.
- Financial constraints: Solid waste management has high operating expenses, although the private sector is more likely to carry out the process with government policies and backing.
- Quick urbanisation: As a result of population growth, waste production has reached an all-time high, putting significant strain on the current management systems.
- Insufficient policy The implementation of environmental legislation is a significant concern, despite the mention of financial constraints.
- Technological gaps: Advanced technology for efficient waste treatment is sometimes lacking in developing nations.
- Problems with waste segregation: When waste is not appropriately separated at the source, management becomes more challenging.
Our ability to handle solid waste properly now will determine how the earth will fare in the future. Solid waste management is a global obligation that every one of us must take on to improve our planet for future generations. The main goal should be to raise public awareness and teach them about solid waste management procedures and how to apply them effectively.
