Project report

Employment Analysis

The intention of this report is to estimate the possible job creation which can potentially be achieved through the digestion of grass. As will become clear, this potential will be assessed through the use of both hands-on experience and literature data. As certain assumptions have to be made to be able to estimate employment, based on different possible scenarios, the result will not be a clear-cut number of jobs, but rather a range, depending on the implemented measures and pathways.

Cost-Benefit Analysis

This report considers the financial and economic effects on the supply chain and the energetic or material usage of these grass residues. One established method to evaluate financial effects is the cost-benefit-analysis (CBA). In cooperation with the life cycle assessment there were several scenarios defined for the CBA of grass usage. These scenarios have been the basis for the following analysis. Cost-Benefit Analysis (CBA) is a tool for assessing economic advantages or disadvantages of one or more investments by calculating the costs and benefits in order to assess the common welfare change attributable to it. Normally a CBA is one of several tools or aspects of a comprehensive assessment like efficiency, effectiveness and ecological assessment. This CBA is primarily done to answer the question ‘does the expenditure of public money on one of these different grass value chains provide a net benefit to the national or regional economy and the European public, bearing in mind that these resources could also be used in alternative ways?’. The CBA offers decision makers a possibility to compare the relative merit of different alternatives in terms of their returns on the use of public resources and is also be used to judge the social aspects on the use of these resources. Following the financial assessment, the effects of different social actions will be considered.

LCA of management strategies for residual grass

The aim of this study is to assess the environmental consequences related to diverse uses of grass residues in Europe. It will answer to following questions :

  • Is the overall environmental performance increased when grass residues are used for biogas, in comparison to their current use
  • What are the differences in environmental performance between different strategies to manage residual grass, in comparison to it’s current management?

Feasibility study of a differentiated system of land owner management-fees

The objective of the study is the definition of the added financial need for farmers due to extensive permanent grassland management. To decrease these costs, the biogas production is taken into account as a possibility of strengthen the farmer income. For this reason, the possible income will be calculated. This to aspects are leading to a price per ha, the water suppliers’ should pay to the land owner. The level of this price will be compared with the willingness to pay by water companies. Therefore the study examines the differences in the economic value of maize silage from arable land in the one hand and grass silage from extensive permanent grassland in the other hand. From the view of a biogas producer, the study is looking for further income beside the energy feed in law mechanism. External wishes caused by water protection issues (grass versus maize) should be internalised due to a new income for biogas installation owners.

Public Financing strategies for the integration of social employment in the biomass chain

The intention of this report is to offer strategies for funding initiatives aimed at the integration of social employment in the biomass chain. In a first chapter, a broad overview of the Social Economy in Europe, and more specifically the institutions and legislation in a selected number of its member states is given, to indicate the recent evolution in this field. A second chapter will go into further detail on the possibilities of social employment in the biomass valorization chain, specifically in the context of the GR3 project. A third and final chapter will first analyze the framework of Services of General Economic Interest, enabling companies to be paid for services by public authorities, without this being designated as state aid. Secondly, the inclusion of social clauses in public procurement will be discussed, as social selection criteria can prove to be a valuable instrument in the encouraging of social employment.

SWOT analysis

The five participant countries have verified that a considerable amount of grass cuttings is poorly valorised in Anaerobic Digestion (AD). This substrate can either be planted for several reasons as soil protection and conservation against erosion and aesthetic, or it occurs from natural vegetation (e.g. road sides, natural parks) and has to be maintained for assuring bio-diversity. Green cover crops have many positive effects on the environment. Furthermore is available both close to the cities and on the countryside, offering an opportunity to increase biogas production. It is crucial to know about the possible cause of this lack of interest, namely to identify the non-technical barriers (NTBs) that hinder the investments. Consequently in this study the identification and role of non-technical barriers and drivers facing the use of grass cuttings in anaerobic digesters was investigated.
