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...
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...
Typically, RFQs require 8,000h of annual plant availability. The wasteWOIMA® design is based on best available technologies (BAT) combined with optimized material and equipment selection to ensure at least 8,200h annual availability.
Better plant availability is achieved through
Longer MTBF
Less maintenance breaks
Shorter maintenance breaks
Less unplanned stoppages

The wasteWOIMA® WtE power plant uses circulation gas and advanced automation with several measuring points and methods to ensure that the incineration on the grate takes place at exactly the optimal temperature. Combined with optimal combustion and post-combustion chamber design, controlled air feed, high-quality thermal insulation / cooling and refractory / Inconel protection leads to extremely low losses on ignition (LOI), i.e. the unburnt carbon content in t...
The Waste Framework Directive (WFD) hierarchy prioritises waste prevention followed by preparing for reuse, recycling, recovery and finally, least favourably, disposal.
WFD Article 3 makes the following definitions:
Recovery means any operation the principal result of which is waste serving a useful purpose by replacing other materials
Disposal means any operation which is not recovery
A Municipal Solid Waste Inci...
The combined continuous savings during the operation and maintenance of the wasteWOIMA® plant amount up to 17,000,000 €.
The savings are mainly a result of
Highly automated plant operations & maintenance work
Optimized equipment in the WOIMAdesign
Waste management and power generation decentralization potential

The wasteWOIMA® WtE plant has been designed for a decentralized waste management and power generation program, where local waste is incinerated to energy locally for local people and businesses. Naturally, the decentralized business model only works for cities/areas large enough to generate enough waste for one large or at least five small-scale wasteWOIMA® plants.
The wasteWOIMA® plant saves on ...
Waste fuels are a quite heterogenous fuel group typically consisting of municipal, industrial and construction/demolition wastes. Their calorific value and moisture content can vary significantly complicating the incineration process and sometimes preventing full combustion.

A waste-to-energy power plant can be a significant source of wastewater, if not designed properly. The wasteWOIMA® WtE plant is a dry plant that only uses dry or semi-dry systems and produces no wastewater. The plant does use water in cooling the bottom ash in the slag pool beneath the grate and in the flue gas treatment (FGT) system, but this water evaporates prior to becoming wastewater.
The wastewater treatment savings in the wasteWOIM...
Water is an extremely precious, and often scarce or hard-to-reach, resource in many parts of the world. The WOIMAdesign ensures that as little water as possible is wasted in the wasteWOIMA® WtE plant mainly thanks to the closed steam-water –cycle. Unfortunately, it is still inevitable that some water (~500-600 l/h) is required to replenish the plant due to evaporation and water quality degradation.
All the water in the wasteWOI...
