A-S-H® Material and Ash Handling

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.

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.

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:

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. 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 to energy is one of the most robust and effective alternative energy options to reduce methane and CO2 emissions.

As urbanization and spending on consumables increases, more solid waste is generated. The amount of solid waste has grown over the last century to more than 3 million tons now generated per day globally, and the number is expected to double by 2025 (Organization for Economic Cooperation and Development).

Solid waste management is often one of the greatest costs to municipal budgets. Increasing the amount of municipal solid waste in landfills translates to increases in greenhouse gas (GHG) emissions, air and odor pollution, and soil and water contamination.

To reduce the size, cost and environmental impacts of landfills, many regions are shifting from a linear economy (make-use-dispose) to a more circular economy model, where materials are made, used and reused to their fullest extent. Complementary to recycling, WtE plants extend the useful life of the solid waste, converting it into electricity and/or heat for industrial processing and district heating systems, filtering out harmful substances and recovering metals and other material for reuse. WtE is one of the most robust and effective energy options to produce power while treating waste and reducing emissions as an alternative to fossil fuels.

Exceptional service and maintenance means improved availability and performance.

Parts wear out. Technology changes. Needs change. Throughout the useful lifetime of a waste-to-energy or biomass plant there will be many reasons to call a service specialist. And not just for service, but for plant improvements and upgrades, too.

Here are just some of the ways we can help keep your facility functioning smoothly and productively, both for short-term and long-term plant operation:

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.

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 are a revolutionary, efficient, and economical way to improve operational accessibility and productivity for waste-fired power plants.

Improved revenue and reduced greenhouse emissions are benefits that come from extended energy recovery by condensation of the hot flue gases.

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

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.

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

At our production facility in Denmark, capabilities such as spiral welding and cold metal transfer welding allow us to design and manufacture boiler tubes and wall panels that can withstand the special operating conditions of WTE applications.

Located in Copenhagen, Copenhill / Amager Bakke sets new standards for environmental performance, energy production and waste treatment.

In partnership with BE&K, B&W engineered, designed, procured and constructed SWA's Palm Beach Renewable Energy Facility No. 2. - one of the largest WtE facilities in the world. And through our subsidiary, we are providing O&M services.

For the first time in Ireland's history, in 2011 20,000 households in Meath County are provided with waste-powered electricity.
