Monetizing wasteWOIMA® Benefits – Early Positive Cashflow Revenue

Due to the faster project development and delivery phases of the wasteWOIMA® WtE plant, it reaches positive net cashflow earlier that traditional stick-built plants. This early positive cashflow can significantly affect the project’s profitability and thus its feasibility. Faster project payback has also a positive impact on WtE plant owner’s gearing ratio, which affects their risk carrying capacity and cost of money. The e...

Monetizing wasteWOIMA® Benefits – Better Condenser Efficiency Revenue

The wasteWOIMA® WtE power plant’s electricity generation capability is somewhat dependent on the plant’s condensing capacity, i.e. the level of vacuum that the condenser(s) can generate to enable the turbine to extract every last ounce of energy out of the steam flow. As standard, the wasteWOIMA® plant uses modular air-cooled condensers (ACC) that are Easy to deliver Fast to install ...

Monetizing wasteWOIMA® Benefits – Better Turbine Efficiency Revenue

There are several steam turbine suppliers in the marketplace even in the small-to-medium-scale range that the wasteWOIMA® WtE power plant represents. Each supplier has slightly different approach to the business with emphasis on e.g. Maximal power output Reliability Low lifecycle costs Easy scalability Resilience to ambient conditions The selection of the right turb...

Monetizing wasteWOIMA® Benefits – Higher Steam Parameter Revenue

Currently, the wasteWOIMA® WtE power plant uses very conservative steam parameters (400oC / 40 barg) to ensure high availability, low maintenance costs and overall reduced risks related to fuel quality. These steam parameters are used independent of the fuel, i.e. even with “easy” fuels that pose less risks for heat corrosion. Several key factors affect the power plant’s power output, such as Steam quality

Monetizing wasteWOIMA® Benefits – Sludge Firing Revenue

The grate firing system in the wasteWOIMA® WtE power plant is quite flexible and can accept a wide range of heterogenous solid waste fuels with LHV above 7 MJ/kg and moisture content below 55%. On top of this, a small amount (up to 10%) of low-calorific-value sludges can be added to the fuel mix and reduced to easily disposable bottom ash (slag) in the grate incineration process. Although the sludges contain very little energy, their small quantity does not affect th...

Monetizing wasteWOIMA® Benefits – Wide Fuel Range Revenue

The waste fuel incineration process is one of the three key functions of any power plant besides the heat recovery boiler and flue gas treatment (FGT) system. Its purpose is to combust heterogeneous solid waste fuels flexibly to homogenous flue gas with good efficiency and with high tolerance for inert particles, such as metals, gravel and sand. Waste incineration is also a major source of income for the plant through tipping fees besides energy sales since w...

Monetizing wasteWOIMA® Benefits – Metals Recovery Revenue

The heterogenous waste fuels, in particular MSW and industrial waste streams, used in waste-to-energy power plants often include valuable materials that can be recovered either prior to or after incineration. Metals, both ferrous and non-ferrous are one group that can quite easily be recovered after incineration from the bottom ash using complementing technologies such as sieving, crushing, as well as ballistic, magnetic and eddy current separation. The bottom ash material co...

Monetizing wasteWOIMA® Benefits – Closed Cooling Circuits Revenue

Any power plant’s efficiency is affected by how much thermal energy is lost through radiation, convection and conduction. The closed cooling circuits of the wasteWOIMA® plant retain all the thermal energy transferred to it via waste incineration or cooling processes. Simultaneously, the closed circuit requires only minimal top up water and produces no wastewater There is significant amounts of thermal energy available in Co...

Monetizing wasteWOIMA® Benefits – Optimized Plant Self-consumption Revenue

Every power plant requires electricity to operate. There are dozens of pumps, fans, valves, actuators and similar required in everyday operations. Combined these form the plant’s self-consumption a.k.a. parasitic load which is the difference between generated electricity (gross MW) and electricity available for sale (net MW). The standardized WOIMAdesign allows us to spend time in finding and selecting the most optimal equipment not only from a quality point of view but also f...

Monetizing wasteWOIMA® Benefits – Long Plant Lifespan Revenue

Typically, waste-to-energy power plants are designed for a 20-to-25-year lifespan. The heterogenous waste fuel cause more wear and tear than traditional fossil or biofuels. The wasteWOIMA® is designed for a 30-year lifespan in the harshest of conditions and with difficult waste fuels. This will enable the plant to continue generating revenue for 5 to 10 years longer, when other similar plants have already been decommissioned. To ensure the long li...
