Waste Management - Introduction

Waste management is an important part of infrastructure for cities, towns and countries. Many consider today’s society to be a throwaway society where commodities are so inexpensive that it’s easier to throw things away that don’t work (rather than fix them) and the convenience of disposable items fits with a person’s busy lifestyle. Many people stuff everything they don’t need into a trash bagand put it outside their home once a week and don’t give it another thought. The result of that thinking is that waste management is huge resource glutton that takes people, money and fleets of vehicles to manage.



  • Waste Hierarchy

    The waste hierarchy refers to the "3 Rs" reduce, reuse and recycle, which classify waste management strategies according to their desirability in terms of waste minimization. The waste hierarchy remains the cornerstone of most waste minimization strategies. The aim of the waste hierarchy is to extract the maximum practical benefits from products and to generate the minimum amount of waste; see: resource recovery.The waste hierarchy is represented as a pyramid because the basic premise is for policy to take action first and prevent the generation of waste. The next step or preferred action is to reduce the generation of waste i.e. by re-use. The next is recycling which would include composting. Following this step is material recovery and waste-to-energy. Energy can be recovered from processes i.e. landfill and combustion, at this level of the hierarchy. The final action is disposal, in landfills or through incineration without energy recovery. This last step is the final resort for waste which has not been prevented, diverted or recovered. The waste hierarchy represents the progression of a product or material through the sequential stages of the pyramid of waste management. The hierarchy represents the latter parts of the life-cycle for each product.
  • Life-Cycle of a Product

    The life-cycle begins with design, then proceeds through manufacture, distribution, use and then follows through the waste hierarchy's stages of reuse, recovery, recycling and disposal. Each of the above stages of the life-cycle offers opportunities for policy intervention, to rethink the need for the product, to redesign to minimize waste potential, to extend its use.[24] The key behind the life-cycle of a product is to optimize the use of the world's limited resources by avoiding the unnecessary generation of waste.
  • Resource Efficiency

    The current, global, economic growth and development can not be sustained with the current production and consumption patterns. Globally, we are extracting more resources to produce goods than the planet can replenish.[24] Resource efficiency is the reduction of the environmental impact from the production and consumption of these goods, from final raw material extraction to last use and disposal. This process of resource efficiency can address sustainability.
  • Polluter Pays Principle

    the Polluter Pays Principle is a principle where the polluting party pays for the impact caused to the environment. With respect to waste management, this generally refers to the requirement for a waste generator to pay for appropriate disposal of the unrecoverable material.





Waste is not something that should be discarded or disposed of with no regard for future use. It can be a valuable resource if addressed correctly, through policy and practice. With rational and consistent waste management practices there is an opportunity to reap a range of benefits. Those benefits include:



  • Economic

    Improving economic efficiency through the means of resource use, treatment and disposal and creating markets for recycles can lead to efficient practices in the production and consumption of products and materials resulting in valuable materials being recovered for reuse and the potential for new jobs and new business opportunities.
  • Social

    By reducing adverse impacts on health by proper waste management practices, the resulting consequences are more appealing settlements. Better social advantages can lead to new sources of employment and potentially lifting communities out of poverty especially in some of the developing poorer countries and cities.
  • Environmental

    Reducing or eliminating adverse impacts on the environmental through reducing, reusing and recycling, and minimizing resource extraction can provide improved air and water quality and help in the reduction of greenhouse emissions.
  • Inter-generational Equity

    Following effective waste management practices can provide subsequent generations a more robust economy, a fairer and more inclusive society and a cleaner environment


Waste Management

  • Issue

    The first impressions, for a visitor in any setting, are based on the cleanliness of the surroundings. Waste management is also an important facet of environment management. Thus, solid waste management is important from both aesthetics & environmental viewpoints. Consequences of poor solid waste management include transmission of diseases, clogging of drains & sewers, contaminated leaching, visual & smell impacts.
  • Background

    Per capita waste produced has increased with the consumption driven economy. Mega cities produce huge quantities of wastes. Handling & disposal of this waste requires ever increasing investments in people, land, energy, transportation etc. Government legislations & guidelines cover:

    • Municipal Solid Waste
    • Bio-Medical Waste
    • Hazardous Waste
    • E-Waste
    • Plastic Waste
    • Mercury Waste
    • Construction and Demolition Waste
  • Relevance to DIAL

    Delhi International Airport (P) Limited (DIAL) is the gateway to Delhi, the capital of India. Perceptions about Delhi & our country are formed in this first interaction. Cleanliness & proper waste management is extremely important at DIAL for ensuring compliances, achieving high ASQ ratings, as a safety measure against bird strikes & for revenue generation.
  • DIAL Management and Actions

    DIAL works exclusively with waste management companies which employ the highest environmental standards to handle different kind of waste streams. DIAL regularly checks to ensure that these standards are maintained. Audits & Inspections are carried out at the waste facilities for this purpose. All waste is appropriately recycled if it makes ecological & economical sense. Despite these efforts to recycle waste wherever possible, there are unavoidable instances where waste cannot be recycled and must be disposed off in an environmentally- friendly way, according to government regulations.
  • At the New T3 terminal DIAL has incorporated:


    • Capability for separation at source by passengers, concessionaires and all service providers.

    • Twin bin system for waste management - Maximization of recycling.
