Topic

Economic and environmental optimization of the use of biomass residues

Aims

  • Development of an assessment matrix for the comparision of the energy and ressource effficiency of plants for energy and material use of biogenic residues
  • Analysis of Strenghts, Weaknesses, Opportunities and Threats (SWOT) on the basis of a comprehensive data colloection
  • Identification and development of energy efficiency optimizied plant systems by a indicator-based analysis

Measures

TUB

To record and evaluate existing processes and technical options, a data matrix is developed from which optimisation potentials can be derived. The deduction of optimisation potentials is allowed by a comparative examination of the resource protection potential and the energetic and material recovery potential. For that purpose a tool was developed that collects and weights relevant operational and process indexes. An evaluation index can be created from this which facilitates a ranking of the examined plants. In the first phase of the project the so far developed numerical tool was tested with archetype-plant. In the further course of the project the numerical tool will have to be evaluated by testing it with practical data.

As supplement to the numerical evaluation process under consideration of relevant conditions of a comparative approach, the use of a SWOT analysis for a comparative consideration of the resource protection potential and the energetic and material recovery potential is planned. The SWOT analysis is applied to a large number of technical solutions and processes. Therefore a suitable benchmark is to be created which will facilitate the comparison of the stages of development of single processes.

BUW

  • Development of an evaluation matrix for comparing energy and material recovery processes in regard to their energy and resource efficiency 
  • Registration and evaluation of existing strengths and weaknesses, especially process- and plant-specific factors, which influence the energy efficiency 
  • Development of solution strategies for optimisation - infrastructure, technology, operation, products
  • Outlining promising scenarios - plant- and process-combinations, overall systems
  • Implementation of results in form of demonstration projects in a second project phase, which has to be applied for

ATZ

The ATZ is examining thermal processes for the energetic utilisation of biogenic residues. Moreover data are provided for the implementation of a SWOT analysis. For this purpose the state of the art of the thermal utilisation of biomass is identified. Finally the optimisation potential is checked to enlarge the range of fuels.

Focus

TUB

  • Anaerobic processes to treat and utilize organic residues
  • Development of an assessment procedure to identify optimization potentials of different treatment steps respectively of the treatment plants
  • Identification of Strengths, Weaknesses, Opportunities and Threats of the treatment and utilization of organic residues
  • Identification of plant-specific optimization potentials to enhance the energy efficiency

BUW

  • Increasing the efficiency of biogenic waste exploitation through optimal processing

ATZ

  • Scanning of the state of the art of thermal processes using biogenic residues
  • Analysis of the potential of biogenic residues
  • Examination of fuels within the scope of combustion tests
  • Identification of optimization potential
