Assessment of Digestate Processing Local Utilization Systems

A bottleneck in the production of bio energy by the use of anaerobic digestion (AD) is the treatment, processing and utilisation of the fermentation end product, the digestate. A further development to existing technologies is particularly in term of finding new sources of raw materials (substrates) like distillers wash or by-products.

Aim of this project is to evaluate technically possible as well as developing technologies that have the capacity to solve existing and approaching problems in the utilisation of digestate.

The main requirements of the considered technologies are: reduced costs, increased efficiency and to gain valuable substances. The examined processes are mainly combinations of established operations that aggravate the complex assessment.

For the mentioned problem of digestate utilisation there is currently no detailed guidebook available. The results will be provided to the circle of potential users as a comprehensible, explicit guidebook. That book will contain reliable numerical data and praxis oriented case studies.

As a result of further development in digestate treatment technology the step from common AD, bio-ethanol and bio-diesel plants to modern and sustainable bio-refineries could become possible. A maximum utilisation of the input substrates increases the total efficiency and valuable output of those processes enormously and disproves the outmoded opinion that environmental care costs money.
