Topic

The project is focused on the hydrothermal carbonisation (HTC) as an innovative conversion process to transform biogenic residual materials into high-quality biogenic solid fuels.

Aims

In close cooperation with the German Biomass Research Centre (DBFZ), the Halle Municipal Water Management and Waste Disposal Company (HWS) intends to use this project to design, set up and test an integrated process for the multiple-stage energetic utilization of biodegradable waste and further biomass fractions. This will represent an independent contribution to efficient exploration, development and utilization of biogenic residual materials. As similar problem situations exist in other communities, the created concept should be transferable to them and thus be subject to repeated use. Initially, the product from this process is planned to serve as lignite substitute for combustion in large-scale power plants. Manufacturing energy pellets will also be examined as a higher-quality utilization alternative.

Measures

DBFZ

The DBFZ analyses the chemical composition of the organic waste and determines its fuel properties, e.g. the heating value. The organic waste is hydrothermal treated in a laboratory autoclave to identify optimal operation parameters and to evaluate the quality of the HTC biochar. Furthermore pellets form HTC biochar are produced and combusted measuring the emissions. Overall assessments identify the energy and economic efficiency and evaluate the greenhouse gas emission saving.

SWH

 The project’s objective is to draw up a concept of innovative, economically advantageous and climate-friendly recycling of biogenic residual materials. Besides the established processes of composting and fermentation, hydrothermal carbonisation (HTC) is looked into as an innovative conversion process to transform biomass produced regionally into high-quality biogenic solid fuels and such materials’ potential of reducing greenhouse gases is evaluated.

Focus

DBFZ

  • Characterisation of raw materials
  • Hydrothermal Carbonisation in a laboratory autoclave
  • Scientific support of the plant operation
  • Energetic utilization of the HTC biochar
  • Concept evaluation, Energy and material balances, Quantification of greenhouse gas emission

SWH

 Altogether, seven work packages determine the focuses:

  • Characterization of raw materials and laboratory analyses as a basis for the technical and commercial preparation of the investment decision (milestone)
  • Erection and operation of the HTC plant, scientific support of the plant operation and energetic utilization of the HTC bio-coal
  • Concept evaluation, energy and material balances, cost accounting
