PART B: VALORISATION PLAN

SECTION I: Testing

1 Has the R & D result been tested?
YES x
     

 

1a In what mode has the result been tested?

•              Prototype

•              Pilot Application

•              Alpha/BETA testing

The anaerobic digester for CH4 production has been tested and pilot experimented for a period of three months for a small scale application 600 lit of dairy slurry. Furthermore, the lab experiments were carried out in two continuous stirred tank reactor (CSTR) (750 cm3 working volume), and simulated production environment focused in optimization of methane production from organic waste. Additionally, the effluent were chemically characterized for the fertilizer value of the effluents
1b. Please describe and discuss the testing results
The wastes used for the experiments are a mix of different organic waste in order to find the best mix analogies of organic matter. Furthermore, the pilot laboratory testing was aimed toward the optimization of the HRT (Hydraulic Retention Time) in conjunction with the highest level of organic loading level. Thus, the experimental phase reduced the HRT of the waste inside the reactors resulting in the reduction of the working volume required to degrade the organic matter and produce higher volume of biogas.

Usually, the HRT of animal waste under anaerobic conditions at the mesophilic range is 30-35 days. The experiment and testing phase has succeeding to reduce the HRT to 25 days. Therefore, the reactor’s volume requirements have been decreased by 25% achieving, so far, the reduction of the reactor cost. Additionally, a feeding system for a mixture of raw material (i.e. poultry and pig waste) was designed to improve the methane production due to the reduction of the ammonia toxicity.

     

 SECTION 2: Current Stage of Development

2a To what extent does the development team have technical resources for supporting the production of a new product? (Researchers, human resources, hardware, etc. )
Industrial design for anaerobic digester for CH4 production and bio-fertilizers is at the stage of market introduction. Moreover, there is interest from farmers, investors and business community to invest in this emerging alternative energy technology. The technology could be enhanced and expanded to the production not only of CH4 but also to H2. In the case of H2 production, additional human and material resources are required so as to prevent the loss of hydrogen produced during the anaerobic process. In order to achieve this result the appropriate instrumentation is needed for the online VFA and the partial hydrogen pressure measurements inside the liquid in the reactor. Additionally, a microbiologist researcher, specialized in the anaerobic treatment, is required to be included in the research team.

 

2b What are the technical issues that need to be tackled for full deployment, if needed?
Although the product has been reached deployment, parameterized optimization system software for optimal case design on each installation will be an attractive feature that minimizes the design cost. Also a complete user manual must be designed to assist users in understanding the usage of this anaerobic technology.

 

2c What additional technical resources are needed for the production of this new product?
Not needed.

 

2d Overall assessment of the current stage of technical development.
This is a well established technology for CH4 production that is already leading into the market. Additional research potentials can enhance the market potential with the production of H2.

SECTION 3: Deployment 

 

3a Define the demands for large scale production in terms of
  • Materials
There is not a plan for large scale production, rather than a customized approach
  • technologies, tools, machineries

SECTION 4: Overall Assessment

1 What is you overall assessment of the technical feasibility of the research result?
Industrial design for anaerobic digester for CH4 production and bio-fertilizers system is totally feasible industrial application of an R&D outcome. This feasibility is documented by the increasing interest of the market to invest on the application of these results in the energy sector. The notion of industrial design derives from the need to proceed for specialized in each application of technology according to testing results of the intended organic material mix in each application. At his stage there is conclusive self sustained service that could be expanded with enrichment of additional research results on H2 production.
