WASTE-TO-ENERGY

WASTE-TO-ENERGY GENERATION

SAEL is the Leader in the paddy straw-led, waste-to-energy generation business in India. It has expertise in the design, construction and operation of a waste-to-energy plant for large-scale generation of power.

SAEL has partnered with global technology suppliers such as BWSC, to develop waste-to-energy technology for Indian conditions. ​With over 10 years of experience, SAEL offers reliable and efficient solutions in the most advanced biomass technologies.

The biomass plants use paddy straw, a by-product of paddy harvesting, to produce energy. Paddy straw, which otherwise would be burned, leading to degradation of soil quality and air pollution, is efficiently converted to energy through an advanced boiler mechanism. ​The company also installs biomass plants for other customers on a BOT (build, operate, transfer) basis.

The Potential & Opportunity for

Waste-to-Energy

Waste-to-Energy power is carbon neutral electricity generated, from renewable organic waste, that would otherwise be dumped in landfills, openly burned, or left as fodder for forest fires. 

Graphic-4.png

Biomass is like solar energy but stored in organic matter. It is a renewable energy source because new plants, trees and crops grow and replenish the supply.

Augmentation of Rural Economy

Generates direct and indirect employment as well as income through the value chain.

Improves 
environmental health and air quality

Sustainably managed agricultural land is healthier. The biomass industry can divert millions of tons of agricultural waste, and prevent openly burning of waste materials and forest fires. It offsets the use of fossil fuels that produce smog and acid rain. 

Reduces reliance on fossil fuels 
Biomass represents a homegrown energy solution and enhances our National security by reducing our dependency on fossil fuels.

Biomass is solar energy stored in organic matter. It is a renewable energy source because new plants, trees and crops will grow and replenish the supply.

Affordable Energy harnessed from biomass is inexpensive, typically costing 1/3 less than energy from fossil fuels.

Key Issues Caused by Burning of Surplus Biomass Material (primarily agricultural residue)

Studies have indicated that the surplus biomass material (230 million metric tonnes) left is disposed of by burning it in the fields. A major cause of air pollution in North India. The ​AQI in Delhi typically reaches 450-1000 in the winter months of October to January due to stubble burning in neighboring areas, which is more than 20 times the limit deemed safe by the WHO and a major cause of deaths from respiratory issues, owing to air pollution in India every year.

The health of nearly 85% of people living in the vicinity of crop/stubble burning areas is directly impacted. ​A study by IFPRI (US-based International Food Policy Research Institute) found that the burning of agri-residue has caused significant air pollution in the country – leading to acute respiratory infection and an estimated economic loss of $35 billion annually.

Apart from smog and a sharp rise in CO2 levels, the paddy-straw burning by farmers also significantly reduces the organic matter. Loss of major nutrients and microbial biomass in the soil affects crops for the next season. One-ton burning accounts for the loss of 5.5 kg of Nitrogen, 2.3 kg of Phosphorus, 25 kg of Potassium and 1.2 kg of Sulphur in the soil. The farmers thus can save Rs. 300 per acre on Fertilizers/ Pesticides.

WASTE-TO-ENERGY SUPPLIER & TECHNOLOGY

SAEL has proven its expertise in the design, construction and operation of biomass plants for large-scale generation of electricity in India, without increasing the carbon footprint. Our biomass plants (15 MW each) are located at Ghazipur, UP, and Muktsar (Channu) Punjab.

 

The generation of electricity with biomass enables us to develop the rural economy, and also renew/replenish resources. With over 24 types of fuels identified, our biomass plants are known for their efficiency and scalability. With over 10 years of experience in this field, we offer reliable and efficient solutions in the most advanced technologies. We also install biomass plants for other customers on B.O.T (build, operate, transfer) basis.

Boiler Technology

SAEL’s boilers are optimized to deliver and maintain high boiler and steam efficiency, low maintenance and operation costs

EQUIPPED WITH THE BEST AVAILABLE TECHNOLOGY

By straw-firing, the bales are conveyed through seal-gate arrangements to the sacrificers where the bale is loosened before it is pressed through the water-cooled ducts to the grate.

SECURED 3 PASS

STRAW-FIRED BOILER

The straw feeding system is adaptable to different types of bales. It is designed to operate with corrosive and sticky ash caused by paddy straw combustion – giving lifetime sustainability.

ADAPTABLE AND LONG LIFE BOILER EQUIPMENT 

SAEL’s plants are equipped with the latest air-cooled boilers instead of the more commonly used water-cooled boilers.
