Renewable energy has big potential for electricity generation

Ramesh Shivanna, former Chairman, Energy and Renewable Energy (E&RE) Committee, Federation of Karnataka chambers of commerce and Industries (FKCCI) and Founding President of Karnataka Renewable Energy System Manufacturer Association (KRESMA) speaks about the importance of renewable energy in India with Worldofchemicals.com & Waste Management Expo 2020.

What is the Scope of Green Energy/ Renewable Energy in the various sector? Shed some light on the concerns and challenges regarding this in India.

India is a fast growing country and second highest population in the world. The power generation Installed capacity in India is 364 GW, out of this Fossil generation is 79.8 percent and Renewable energy is only 17.3 percent. 

As per the Paris agreement, India has committed for 40 percent of the Energy source to be Renewable energy by 2030. We have scope of about 23 percent to build the capacity in the country. 

The different Renewable energy sources are Wind, Solar, Small hydro, Biomass, waste to energy, the present wind installed capacity is 45 percent, Solar is 36 percent, Biomass is 12 per cent, Small hydro power is 5.7 percent, and waste to energy is only 0.2 percent 

All the renewable energy resources are natural resources and have big potential for electricity generation. Perhaps they have different challenges.

Comparisons of costs per kilowatt-hour of electricity produced show that newly built solar and wind plants are considerably becoming cheaper. In the coming years solar and wind energy will compete more favourably with conventional energy generation.

Cement industries play major role in co-processing hazardous wastes

What are the concerns & issues regarding the waste generated in the industries (your focus industry) in India?

Segregation of waste from source level is the key matter of concern in Industries for recycling. However segregated storage followed by disposal may not be the main part of the industry’s priorities. Their commitment towards the environment will definitely motivate industry to do so.! 

What are the technologies used to treat the industrial waste and make it a sustainable or usable alternate thereafter? Also, elaborate regarding the national scenario of solid waste management and methods managing the hazardous constituents?

Waste disposal hierarchy pyramid shall be followed in the disposal of waste. The landfill may be last in the pyramid, despite co-processing of waste is kick-starting across the country. Mostly cement industries play a major role in co-processing these hazardous wastes.

However, policy-driven enforcement similar to hazardous waste shall be applied to other solid waste such as e-waste, plastic waste, domestic solid waste, especially on construction and demolition waste. Stricter enforcement and abiding Extended Producer Responsibility may better the scenario in the country.

BIAL takes the lead in waste management, plastics recycling efforts

Lakshminarayanan S, Vice-President, Engineering & Maintenance, Bangalore International Airport Limited, who is spearheading the sustainable initiatives of BIAL discusses about water, waste and power management with worldofchemicals.com & Waste Management Expo 2020.
Mention the concerns and issues regarding solid waste generated at the airports. How important is solid waste management for Bangalore International Airport Limited (BIAL)?

At BIAL, we aspire to be a role model in sustainable development and, accordingly have embedded principles of sustainability into all aspects of our business. Solid waste management is one of the focus areas of sustainability. 

Airports must manage all the regular concerns of waste management, including the lack of environmental awareness, complexities in influencing adaptation of waste management practices etc. In an airport ecosystem, solid waste generated is both from airport operations as well as from flights that land in the airport. Various countries and cultures have different ways of treatment and disposal, thus some issues specific to Airports include:

International travellers:
  • Lack of awareness of local regulations with reference to the use of plastic and segregation at source
  • Limited/ inability to read or understand local language and directions
Incoming aircraft
  • Receiving plastic which is banned
  • Segregation of waste and separation of liquids and food from plates, bottles etc on-board incoming aircraft 
  • Lack of identification of contaminated biowaste
