„BiWaRE“ - Biomass and Waste for Renewable Energy - Development of an integrated ‘decision support system’ for the application of renewable energy technologies from organic substrates with applied examples from Vietnam and Thailand - implementation through networked experience of technology and training
Renewable energy refers to energy resources that are replaced rapidly by natural processes, e.g. solar, geothermal, wind and biomass energy. Against the background of the worldwide increasing energy demand, the depletion of natural resources and global warming, renewable energy using biomass and organic waste represents a sustainable alternative for energy development all over the world.

Two forms of energy production are particularly interesting for decentralised applications in countries like Vietnam and Thailand: the generation of biogas by anaerobic digestion of organic substances and by thermal processes. Due to the climatic conditions and the economic structure, organic substrates from agriculture, forestry, households and industry or waste are very abundant. Renewable energy can provide environmentally, economically and socially sound energy supply to households and comanies. Furthermore the solid product can be utilised as a secondary fertiliser, representing the recycling of valuable substances, like phosphorus.

The application of renewable energy needs promotion. Typical constraints are legal and institutional barriers, the lack of technology transfer, know-how and systematic data for developing renewable energy policies on supply and demand.
The purpose of this project was to develop an integrated 'Decision Support System' (DSS) for the application of renewable energy technologies from organic substrates, by biogas and biomass combustion processes.

Furthermore training materials have been developed, to integrate the results into the curricula of the BiWaRe Partner Universities in Vietnam, Thailand, Germany and United Kingdom, contributing to a more practically oriented and innovative education.
Decision Support System (DSS)
Many factors need to be considered for the selection of energy options, e.g. energy demand, site conditions, socio-cultural framework, socio-economic implications, legislation and policy, and the economic feasibility. In addition, with biogas and biomass combustion, even more factors need to be evaluated, e.g. the quality and quantity of suitable substrates, seasonal distributions, shwlf life and logistics, etc. Therefore the assessment of the feasibility of potential projects is complex, especially for decision-makers or planners, who are not familar with renewable energy from organic substrates.

The Decision Support System supports decision-makers and planners for an initial evaluation, whether biogas or biomass combustion could be a feasible option for their energy project, e.g. the electrification of a particular community or the supply of an industrial firm.

The DSS integrates all relevant aspects, like energy production and utilisation, predimensioning, framework conditions, socio-economic and environmental impact as well as project economics. Thus it has a unique quality.

The DSS is intended to be applied during the first stages of the project development. Its application represents a pre-feasibility study and leads to an initial decision, whether or not biogas or biomass combustion is potentially suitable for the project in question and whether it is worth to proceed with a costly further project development.

The DSS is provided in form of a handbook and a digital version.
