Decision making process

Name of the case study
Municipal System for Biogas Extraction and Utilisation

Decision making process - stages
The process comprises several steps: the Municipal Council has made the decision to develop the project; a partner search for development of the project; project development; project assessment by the Municipal Environmental Commission; final decision for the project implementation; monitoring of the system exploitation and efficiency.

Decision making process - levels
The Municipal Environmental Commission employs experts to consider and discuss environmental project proposals. Their opinions are then reported to the Municipal Council that is to take a political decision.

Decision making process - sources of information
The assessment was based on information provided by E-Plus computer program which collected the database for the biogas production at Bratovo landfill. This program uses a first order decay function as a basis for calculating methane generation. The main inputs to the model were the quantities of annual waste disposal registered since the landfill opened in 1983 and a forecast of future waste disposal rates.

Decision making process - who are the decision makers
Both experts and municipal politicians were involved in the decision-making process at different stages.

Decision making process - who made the final decision for project implementation
The Municipal Council made the final political decision for the project implementation.

Name of tool
Multicriteria analysis (Brown, Vence and Associates, Inc.)

Decision making process - tools in decision-making process
The tool was implemented by experts at a preliminary project stage. The Multicriteria approach was applied to assess the economic, environmental and social benefits provided opportunities for choosing the sustainable solution of using biogas. The decision taken for applying the utilisation system for biogas extraction was a solution for solving the environmental problems whilst obtaining economic benefits.

Quantitative goals/benchmarks defined by the tool were:
Environmental goals
The biogas system implementation was expected to reduce greenhouse gas emissions, water and air pollution. Benchmarks used were consistent with national standards. The proposed ?LBG-to-electricity? Plant, reduced uncontrolled emissions of methane and carbon dioxide to the atmosphere, compared to a landfill without a conversion plant, where methane is released to the atmosphere.
Economic goals
The comparison of different system alternatives was based on expert-defined criteria. It was used to assess the project revenues from electricity sales.

Decision making process - how was the information for the dmp disseminated
A workshop on LBG utilisation technologies in Bulgaria involving multiple parties - local and national government representatives, private enterprises, and media representatives, further expanded the knowledge regarding LBG conversion. Also, by convening these different parties, an implementation network was initiated for promoting the installation of an LBG conversion system at Bratovo Landfill and for encouraging LBG use in other parts of the region.

Decision making process - how was the public involved
The municipality and BVA experts organised public demonstrations of principle approaches and results of biogas practical implementation during the project development in order to increase public awareness and commitment and to assess attitudes of different groups.

Decision making process - was there public discussion over the project
