How waste-to-energy works
A waste-to-energy plant converts solid waste into electricity and/or heat - an ecological, cost-effective way of energy recovery.
Proper planning and financial constraints have limited many developing nations ability to meet simple health standards that provide healthy living conditions. In fact every nation faces the challenge of an ever increasing costly waste management solution.
Waste-to-energy is a way to recover valuable resources.
Waste-to-energy isn’t just a trash disposal method. It’s a way to recover valuable resources. Waste-to-energy is a vital part of a sustainable waste management chain and is fully complementary to recycling.
Convert waste to energy and you can recover 2/3 as CO2-neutral fuel.
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.

Modern waste-to-energy plants have the lowest level of emissions of all industrial sectors. In fact, emissions from our facilities are healthier to breathe than the air in many cities.

99% thermal efficiency, 95-99% clean flue gas with BAT (Best Available Technology).
Our BAT technology guarantees very high efficiency (99%) and ultra-low emissions (95-99%). BAT is the product of years of research, and is the answer to the needs of future generations of waste-to-energy plants.
Turning Waste into Energy
SYNERGY AMERICAS has implemented a number of breakthrough technologies that:
  • Allow using a wide range of waste types as feedstock.
  • Produce no toxic air emissions, and minimize solid by-products.
  • Highly improve the energy efficiency of transforming the waste-into-energy.
  • Enable the process to be cost-effective and profitable even at a very small scale.
The Four Stage Process
1. Pre-Treatment
The Process begins with Sorting, Crushing, and Dehydrating the feedstock. The conditions of this process depend on the type of waste that will be turned into energy. SYNERGY AMERICAS´ technology is suitable for a broad range of waste types and operating conditions. We have a number of pre-treatment processes that adapt to the waste's specific composition and water content. We have implemented solutions that process:
  • Municipal Solid Waste
  • Industrial Residues including plastics, mixed materials, paper, cardboard, etc.
  • Commercial and Institutional Waste including mixed waste from Hospitals, Airports, Malls, etc.
  • Agricultural Biomass including crop stocks, bagasse, pulps, hulls, grains, etc.
  • Forestry Biomass including woodchip, sawdust, bark, branches, etc.
  • Animal Biomass including manure, fats, etc.
  • Food Residues including raw and processed elements as well as used cooking oil.
  • Sewage Sludge, and other special applications.
2. Gasification
Our equipment generates very controlled conditions under which the specific waste type will decompose from complex into simple molecules. This combustion-free process results in minimal quantities of heavy gases and toxic materials. SYNERGY AMERICAS´ technological processes generate remarkably high yields of usable hydrocarbons across waste types. In addition, the energy consumed during the process is reduced, since a percentage of it comes from the use of by-products from later stages in the process. The result of this process is a highly rich synthetic gas (syngas) together with large amounts of super-heated steam.
3. Gas Conditioning
The gases are treated using our advanced BAT injection technologies that safely remove the heavy elements. This process results in plant emissions that comply with the most stringent air regulations. The result of this step is an exhaust gas without dioxins & furans and without any contents of sulfur, NOx, and SOx pollutants.
4. Heat Energy & Syngas for Potential Recovery and Power Generation
The Waste to Energy process produces high amounts of super heated steam and also synthetic gas that are both used for power production. Excess heat may also be used for industrial purposes or for communities.

The “SYNERGY AMERICAS Gasification System” is a highly efficient technology for converting variable wastes into useful and valuable thermal energy, offsetting the need for production elsewhere and thus reducing the total draw on the local grid.

The WtE Gasification System converts upwards of 99-percent of the energy available in the volatile portion of the annual waste stream and sends approximately 95-percent to the boiler or to other energy recovery equipment, like our Combined Cycle Turbine that operates both with steam & gas adding a surplus of 40% power to the system.
Smart and Clean, Efficient, Cost Effective & Proven Technology
The SYNERGY AMERICAS Gasification System uses tried and tested technology to harness this energy. Super-efficient boilers and steam turbines convert the hot exhaust gases into electricity and this process also generates large quantities of hot water, ideal for space heating, drying or chilling i.e. air- conditioning.

Additional Power Output by the Combined Cycle Turbine
Combined Cycle Power Plant
Gas and Steam Turbine
The Combined-Cycle unit combines the steam turbine and gas turbine thermodynamic cycles by using heat recovery boilers to capture the energy in the gas turbine exhaust gases for steam production to supply a steam turbine.
Core Advantages:
  • The ability to increase or decrease electricity production quickly and efficiently.
  • The emphasis on speed and efficiency is because other baseload power plants cannot do that, which complicates the process of compensating for/meeting sudden spikes in electricity demand.
  • Peaking power plants are usually powered by gasoline or natural gas burning engines which can be switched on and off quickly to meet demand, but they are not the most economical generators.
  • They are normally used to backup coal, nuclear, thermal natural gas (steam), combined cycle, geothermal, wind, and other types of power plants when electricity demand peaks.
  • SYNERGY AMERICAS says that this FlexEfficiency* 50 power plant enables its operators to increase its power production at a rate of up to 50 MW per minute.
  • SYNERGY AMERICAS says that this invention can also start operating within 30 minutes.
  • Combined Cycle power plants usually operate by first using a gas burning engine such as a gas turbine to generate electricity, and then use the heat radiated by the gas turbine to boil water into steam. The steam is then passed through the steam turbine which also generates electricity.
  • Gas burning engines generate mechanical, electrical, and heat energy. Mechanical energy is produced by turning the turbine blades. That mechanical energy is converted into electrical energy by an alternating current generator.
  • Less than 40% of the energy generated by a gasoline burning engine is electricity. The rest of it is heat, most of which is wasted by the engine itself. The alternating current generator does waste a little, though. Roughly 90% of the heat generated by the turbine is available to boil water.
  • Boiling water causes it to expand and then become steam (water vapour). The steam pressure is allowed to build up and rushes through the steam turbine, turning it.
  • SYNERGY AMERICAS says that this power plant can operate very efficiently (60% efficiency) at even 40% of the rated power production capacity.
