Objectives

 

The specific objectives of ENERCOM are:

  • Demonstrating a polygeneration concept for electricity, heat, high-value compost/fertiliser and renewable solid substitute fuel from sewage sludge, greenery waste and biomass residues which, if replicated in the existing 3,000 composting plants in the EU, allows exploring an energy generation potential of at least 56 TWh, thereby solving the problem of sewage sludge disposal and responding to the increasing reluctance in the EU to compost-based produced food.
  • The demonstration plant shall produce 2 GWh electricity, 4 GWh heat, 3,200 tons (10GWh) pellets/ briquettes, and 2,300 tons of enriched compost per year. The decision if pellets or briquettes will be produced will be taken at milestone 1 in month 12.
  • Until the district heating grid for the new industrial site nearby is finished, the heat will be used entirely in the plant, thereby maximising the pellet/ briquette production. The plant will increasingly supply heat to the grid, reducing pellet/ briquette production in a first stage – still during the project. After successful demonstration in the project, the plant is planned to be successively extended by further gasification/ CHP modules. The fine-tuning of the energy and material flows for each stage of plant extension will be done in pattern with the results of the RTD on material flow management.
  • Demonstrating the very efficient drying of sewage sludge from 27% DS content up to 65% DS content by mixing with greenery waste and biomass residues and making use of low-temperature environmental heat and heat from composting.
  • Ehancing the overall efficiency by an atmospheric stationary fluidised bed gasifier (FBG) developed in a previous FP5 project.
  • Demonstrating the flexibility of the proposed polygeneration with regard to energy and material flows, responding in a flexible manner to varying market conditions and changing legal frameworks.
  • Providing a more efficient way to remove heavy metals and other harmful substances from sewage sludge by concentrating them up in the ash of a gasification process and removing them through an innovative separation process.
  • Providing a path for recovering minerals and nutrients not only from sewage sludge, but also from biomass used for energy generation, by combining energy generation with compost production, allowing for efficient Recycling of minerals and nutrients from ashes.#
  • Improving the general efficiency through application of material flow management methods.
  • Developing and certifying a new storable industrial substitute fuel.
  • Providing the basis for the creation of two new companies (SME):
  • Contracting company , selling energy and fuel to industry
  • Engineering and general Contracting company for fluidised bed gasifiers and energy plant concepts.
