Waste Management
Adani Enterprises is committed to sustainable waste management practices and comply with all applicable regulations for different kinds of wastes being generated by its businesses. Our integrated waste management across the waste types from collection, segregation, recycle, reuse, transportation, disposal practices etc., such that there is minimum or no impact on surroundings, communities, and the environment.
1,16,584 MT
Waste diverted in FY 2022-23
Waste Management Practices and Commitments of AEL:
Environmental Laws and Regulatory Compliance
By staying abreast of evolving environmental legislation, we ensure that our waste management practices consistently meet the highest standards.
Extended Producer Responsibility (EPR)
We actively participate in Extended Producer Responsibility programs to responsibly manage specific types of waste, including e-waste, battery waste, and plastic waste.
Reverse Vending Machines (RVM)
To promote plastic bottle recycling, Reverse Vending Machines (RVM) are installed at Mumbai and Ahmedabad Airports, encouraging travelers to recycle their plastic bottles
Mining Overburden
Mining overburden is repurposed and used for backfilling within the mines, reducing waste generation and optimizing resource utilization.
Certified Landfill Sites
For waste that cannot be recycled or reused, we have established robust mechanisms for proper disposal via certified landfill sites which adhere to regulatory standards, ensuring the safe and environmentally sound handling of hazardous and non-hazardous waste.
Case studies
Organic Waste Management through Biogas Plant at TRV Airport
Thiruvananthapuram International Airport adopts a cradle-to-cradle approach to waste management, focusing on Refuse, Reduce, Reuse, Repurpose, and Recycle principles. With around 500 kg of organic waste generated daily, we have implemented an advanced Bioenergy Plant to treat this waste.
The Biogas plant converts the collected bio/organic waste into electricity using a 15 kVA Biogas Genset, which powers the in-house plant operations. The Biogas slurry generated from the process is used as manure for horticultural purposes, ensuring a closed loop waste management system.
This initiative also aims to create awareness among the workforce, promoting waste segregation and management practices within their communities. Monthly sessions on waste segregation and indigenous techniques further contribute to cleaner lifestyle choices for our employees and broader positive impacts on society.
Adani Solar: Selling 100% of the Calcium Fluoride (CaF₂) Sludge
As a responsible corporate entity, Solar Manufacturing business is committed to environmental sustainability and takes pride in its efforts to save the environment. In line with this commitment, we have successfully implemented a strategy to sell the sludge material generated from our processes to recyclers. The recyclers primarily utilize the CaF2 sludge as a raw material for wall putty production.
This innovative approach not only reduces the burden on solid landfill sites but also promotes the recycling and reuse of valuable resources in other industries. By offering the sludge material to recyclers, we actively contribute to the circular economy and the conservation of natural resources.
Utilization of Pond Ash in Road Construction
Disposal of pond ash generated by Thermal Power Plants (TPP) is a great challenge. The ash is generally stored in ash ponds in TPP which puts a huge requirement on land and causes negative environmental impacts. The Fly Ash Management Rules mandates use of it in road construction, ash-based products, soil conditioner etc. The TPPs had to supply it free of cost, including transportation cost, to users within 300 km of TPP.
Taking this as an opportunity, our roads business has started using pond ash for Reinforced Earth wall filling in road construction. The plan is to use 8 MMT of pond ash per year. This leads to protection of topsoil and other soil which is generally used for this purpose. The other benefits are in terms of preventing contamination of air, water & soil as the use of pond ash in road construction permanently locks the same. In addition to environmental benefits, the business gets benefitted financially too as pond ash is supplied free of cost by TPP at the point of use.
