Waste to Energy
for a Sustainable, Circular Economy

What is Waste to Energy?

Ecologically Sound, Cost-Effective Energy

Waste to energy (WtE) is a vital part of a strong and sustainable waste management chain. Fully complementary to recycling, it is an economically and ecologically sound way to provide a renewable source for energy while diverting waste from landfills. 

Our WTE technology has been developed and proven around the globe, including:

  • 100 plants in North America,
  • 500 in Europe
  • and 1,600 in Asia.

 

  

How Does Waste to Energy Work?

A WtE plant converts solid waste into electricity and/or heat - an ecological, cost-effective way of energy recovery.
 
A waste-to-energy (or energy-from-waste) plant converts municipal and industrial solid waste into electricity and/or heat for industrial processing and for district heating systems – an ecologically sound, cost-effective means of energy recovery. The energy plant works by burning waste at high temperatures and using the heat to make steam. The steam then drives a turbine that creates electricity.

Energy-from-waste is a way to recover valuable resources
 
Energy from waste (EfW) isn’t just a trash disposal method. It’s a way to recover valuable resources.

Today, it is possible to reuse 90% of the metals contained in the bottom ash. And the remaining clinker can be reused as road material. 

The results and benefits are proven:

  • Avoids methane emissions from landfills
  • Offsets greenhouse gas (GHG) emissions from fossil fuel electrical production
  • Recovers/recycles valuable resources, such as metals
  • Produces clean, reliable base-loaded energy and steam
  • Uses less land per megawatt than other renewable energy sources
  • Sustainable and steady renewable fuel source (compared to wind and solar)
  • Destroys chemical waste / conventional HAPs
  • Results in low emission levels, typically well below permitted levels
  • Catalytically destroys NOx, dioxins and furans using an SCR

High efficiency and low emissions

Waste to energy is one of the most robust and effective alternative energy options to reduce CO2 emissions and replace fossil fuels.

Approximately 2/3 of household waste is categorized as biomass. Therefore, we can recover 2/3 as CO2-neutral energy and reduce our dependence on fossil fuels.

In Europe, 50 million tons of waste is converted into valuable energy through WtE technology, supplying 27 million Europeans with electricity. Still, 50% of municipal solid waste becomes landfill. This releases greenhouse gasses like methane which is 21 times more powerful than CO2. Our WtE technology eliminates these emissions.

Our goals are two-fold: to maximize production and efficiency to meet energy needs, and to reduce our environmental footprint. 

Waste facts

  • 4 tons of waste equals 1 ton of oil
  • 2 tons of waste equals 1 ton of coal

How waste to energy works

Waste-to-Energy Steam Generation

Mass-Burn or Refuse-Derived Fuel (RDF)
B&W provides two boiler options when using waste as a combustion fuel. Mass burning municipal solid waste uses the refuse in its as-received, unprepared state. The second technique uses prepared refuse, or refuse-derived fuel (RDF), where the as-received refuse is first separated, classified and reclaimed in various ways to yield salable or otherwise recyclable products. The remaining material is prepared for firing in the boiler.

Combustion Technologies
B&W Vølund DynaGrate® pivoting combustion grate and Precision Jet® overfire air system are advanced designs that provide environmental benefits during combustion:

  • Destroy dioxins and furans
  • Minimize formation of NOx and CO
  • Minimize unburned carbon


WASTE-TO-ENERGY TECHNOLOGIES

Combustion Grates & Stokers

Combustion Grate
In a waste-to-energy plant, the grate is where waste is converted into energy – the heart of the system. Over the past 80 years we have supplied more than 500 combustion grates worldwide. 

Waste Fuel Feeder Systems

Fuel Feeding Systems
Steady and continuous feeding of fuel in waste-to-energy plants is the key to stable operation, maximum efficiency, and lower operational and maintenance costs.

Water-Cooled Wear Zones

Water-Cooled Wear Zones
Water-cooled wear zones are a revolutionary, efficient, and economical way to improve operational accessibility and productivity for waste-fired power plants.

Energy   Recovery

L90 Waste-to-Energy Plant
Improved revenue and reduced greenhouse emissions are benefits that come from extended energy recovery by condensation of the hot flue gases.

VoluMix   Systems

VoluMix
Proper turbulent mixing of the flue gases in the boiler furnace provides a better combustion process and burn-out in the gas phase.

Emissions   Control

SCR System for NOx Reduction
As a single-source supplier, we can develop an integrated multi-pollutant strategy to match your long-term requirements.  Through every phase of the project, we take time to determine your needs and recommend a customized solution.

Conveyance Systems

Conveyor Systems for WtE
B&W Loibl's conveyance systems can be ordered in various shapes, designs or materials depending on need and conveyor arrangement. These environmentally friendly systems reduce emissions and are engineered for high operational safety.

Flue Gas Treatment

Flue gas cleaning
Our flue gas cleaning systems are purpose-designed to treat the gas so emission limits meet acceptable margins during fluctuations in the gas composition.
