Waste – a valuable fuel

Watch our video and hear the story of one of our customers. Around the world, waste generation rates are rising due to rapid population growth and urbanization. Poorly managed waste negatively impacts the entire planet instead of making use of this renewable energy source. Reliable and highly efficient equipment ensures an environmentally friendly and profitable Waste-to-Energy (WtE) process.

WtE is the best way to get rid of the garbage efficiently and environmentally friendly. With Siemens products for waste treatment the company aims to support a circular economy without landfilling unprocessed waste.

How to turn trash to cash?

Feeding electricity to the local grid can be a valuable byproduct and an additional source of revenue for WtE facilities. With modern technology solutions WtE plant operators can also generate heat power both at high and low temperatures and then distribute it for district heating purposes or utilized for specific thermodynamic processes, e.g. desalination.

Sustainable waste treatment

Siemens calls for an economic cycle that does not waste any of its raw material or fuel by recycling garbage in a closed cycle economy.

A Waste to Energy (WtE) plant contributes to a properly, environmentally friendly, and profitable way of managing waste. Siemens supports its customers in waste management. As a solution and consulting partner we want to get the most out of this valuable fuel.

Solid waste is part of our daily lives. Garbage, agricultural waste, wood chips but also industrial waste usually are in a solid state. As a reliable partner Siemens offers customized power generation solutions. The steam turbine generator set utilizes energy most efficiently and reliable equipment offers a sustainable business model for plant operators.

Industrial steam turbines

Most often used in WtE plants, power output 20 MW to 200 MW:

SST-200, SST-300, SST-400, SST-600

Industrial steam turbines

Generators up to 370 MVA

Most often used in WtE plants power output > 25 MVA:

SGen-100A/SGen-1000A generator series

Generators

Gasification technology can be used to produce low-carbon fuels from municipal solid waste. The synthesis gas needs to be compressed to high pressures. Highly efficient DATUM compressors, driven by Siemens steam turbine, reduce the plant’s demand for electricity.

Process Control and Plant Automation

Process Control and Plant Automation are vital elements of any Energy from Waste plant, whether this be the control of the energy conversion process itself or the automation of a material recovery facility. Siemens provides a standardized approach to both the continuous and discrete worlds of plant control and automation based on a standard hardware platform and open network systems such as Profibus designed to add value to the operation of the plant.

Process Instrumentation

Measuring, positioning, recording and controlling are key requirements for all industrial processes. Process instrumentation from Siemens satisfies these demands and provides an efficient means to increase plant efficiency and improve process quality.

Continuous Emissions Monitoring

Siemens expertise in process analytics can help you to meet all the legislative requirements for a Large Combustion Plant (LCPD), Waste to Energy unit (WID) or other pollution control needs (IPPC). We can also help you to make your installation as efficient as possible.

Fire and Security Solutions

Siemens designs, installs, and maintains security and fire protection solutions that deliver improved operational performance, greater economies of scale, and safeguard your people, processes, information and assets. We focus on your requirements, risks and business procedures and deliver fully integrated systems that will add real value, as well as protecting your organisation.

Energy Management

Siemens will work with you to help use energy more economically across your buildings, not only making the workplace more comfortable and able to react automatically to weather conditions but also to reduce energy consumption. We have developed a complete toolkit of products, services and solutions to assist all areas of industry and commerce to optimise energy and utility consumption.

Power Transmission and Distribution

Reliable energy supply is the key to success for every business. Siemens provides customized solutions to the individual requirements of your substation and monitors all relevant components of your electricity supply network – from transformers and switchgear to overhead lines and cables.

Water Management

Siemens provides a range of water technologies for the Energy from Waste market, including anaerobic digestion, water disinfection, odour abatement, membrane technology-based solutions for boiler feed water make-up, biological wastewater treatment, water re-use and rainwater harvesting.
