Online tool for pig manure processing cost in Flanders

INTRODUCTION

The present tool has been designed to provide an online test for evaluating the economic feasibility of different nutrient recovery technologies.

The tool has been developed by a study simulating the competition of manure waste treatment technologies in Flanders. Since the model calculates the competition in all 331 communities in Flanders simultaneously, there are plenty of results to show, but only the most representative were selected. The online tool makes it possible to screen the results clustering them at province level and underlying these figures in more detail. This is done by interactive maps of the Flemish communities, in which the user can identify the most competitive manure treatment technologies in every community, for different cost scenarios.

HOW DO I USE THE TOOL?

This online tool provides a graphical overview of how much pig manure is processed depending on the type of technology and the cost, for the region of Flanders. Therefore, the user can select at which cost level and for which technology a map of Flanders is shown.

Each figure is associated to a single cost level and contains different maps for every manure processing technique. Only the techniques that are actually adopted in at least 1 community are shown. Techniques can be selected in the right upper corner of each map. By clicking on a community, the user is shown how much pig manure is processed by each technology.

WHICH ARE THE TECHNOLOGIES?

Every technology consists of different combinations of the ManureEcoMine unit processes.

Process unit(s)

  • Centrifuge + Biology liquid fraction
  • Centrifuge
  • Acidification + Centrifuge + Struvite +  Biology liquid fraction
  • Acidification + Centrifuge + Struvite
  • AD + N stripping
  • AD + N stripping + Centrifuge
  • AD + N stripping + Centrifuge + Biology liquid fraction
  • AD + N stripping + Centrifuge + Struvite + Biology liquid fraction
  • AD + N stripping + Centrifuge + Struvite

COST LEVELS

The ManureEcoMine technologies compete in waste treatment market, and these technologies deliver a service to its customers by accepting their unwanted waste product, namely manure. This monetary value is region dependent and logistically complex, e.g. it is dependent on the distance to the nearest disposal space, the manure treatment practice of neighbouring communities, the transport cost of waste products disposal, etc. This value is captured endogenously by the model and is not user-defined.

All other costs and benefits related to technologies (CAPEX, OPEX, revenues from fertilizer and biogas) are (fixed) parameters that are defined by the user prior to modelling. Together, these fixed costs and benefits (so excluding the revenues of accepting manure) constitute the financial gap. This value, if positive, equals the amount of money the technology lacks to be profitable. This financial gap serves as input for the model. In the simulation, the model calculates the value created by accepting manure in the manure market, in order to arrive at a final, spatially explicit analysis of competitiveness.

Simulation thus requires an estimation of the financial gap, and the user can choose between different cost levels L1-L10, where L1 refers to the baseline estimation of the cost of the technologies, and L2-L10 refer to costs decreased incrementally by 5%, as shown in the table below. Every map is associated with one cost level between L1-L10.

By clicking on each cost level (L1-L10), the user can visualise the technologies application in the region of Flanders at the corresponding cost reduction. The maps will open in a new browser tab.

AN EXAMPLE

Figure 1 shows the map that was generated by selecting cost level L5 on the MEM website and selecting the technological scheme “Acidification + Centrifuge + Struvite + Biology liquid fraction”. The map shows the distribution of the optimal application of this technological combination in Flanders, if costs of the technologies would be as specified in Table 2 at level L5, indicating a 20% cost reduction of the ManureEcoMine unit processes compared to the baseline estimation.

Communities in grey have 0 potential for this combination, indicating that benefits do not cover costs in these places. On the other hand, in blue communities the process is economically viable, and the darker the shade, the higher the potential amount of manure processed. By clicking on individual communities, we get an idea of the manure processing mix in those communities. For example, if we click the municipality “Hoogstraten” in the upper north, we learn that both schemes “Centrifuge + Biology liquid fraction” and “Acidification + Centrifuge + Struvite + Biology liquid fraction” are both economically viable at a potential capacity of respectively 193,743 and 63,584 ton pig manure.
