Welcome to the logistical component database which you can access underneath (click on numbers in last column)!

The database on logistical components was elaborated in WP3.  In the underneath table an overview is given of all logistical components included in the database organised in categories and sub-categories according to the main functionalities it has. In the last column of the table users can click on the icon to enter the detailed characteristics of every logistical components included in the database. It includes a long list parameters for pre-treatment, storage and transport technologies that are needed to deliver biomass feedstock of a specified quality at the correct moment to a processing technology. In the current version of the database per conversion technologies parameters are specified on general properties (e.g. functionality, technology readiness and number of systems already in operation), technical properties, biomass input and output specifications and financial and economic properties. 

A logistical component is one of the links in the biomass value chain from biomass to (final) conversion. Examples are pre-treatment, storage and transport technologies that are needed to deliver biomass feedstock of a specified quality at the correct moment to a processing technology. Before the database was filled a selection was made of relevant logistical components and how they needed to be characterised in the database. This is described in D3.1 together with an overview of the populated database.  Using the information on logistical componenents and making an inventory of existing logistical value chains developed in various European projects, the most important logistical concepts were characterised in D3.2

The logistical concepts selected and described in WP3 have been further tested in several case studies using different tools supporting the design and evaluation of biomass delivery chains through formalised steps and evaluation indicators. The LocaGIStics and BeWhere tools were developed and implemented in a stepwise approach for the regions of Burgundy and Aragon . The reports can be accessed here: Burgundy case study, Aragon logistical case study. For the Finish case study the BeWhere and the Witness simulation models were implemented and this is described here: Finland logistical case study. An overview of all 3 case studie approaches and key messages is given in deliverable D3.4 & 3.6

GENERAL PROPERTIES
Commercial name Dorset
Main category Drying
Subcategory Forced drying: belt dryer
Image url http://www.dorset.nu/en/page/home-gm/processes drying.html
Most common/suitable applications Drying solid biomass, manure
Main operating principle:
The Dorset Dryer is a conveyor belt dryer. The conveyor belt consists of perforated steel plates, which are covered with a smooth coating. This allows for greater layer thickness (15 - 40 cm), which guarantees a high drying efficiency. This, moreover, makes it possible to build a more compact dryer. The steel plates are pulled around by a roller chain. Dispensing starts on the top layer, after which the product is transported to the dryer via the conveyor. During this process, warm air is sucked through the dryer. If a liquid product is being dried, then this product is first transported to a mixer. The mixermixes a new moist product with a previously dried product. This has a number of advantages. The product can be transported into the dryer with a small percentage (a minimum of 8%) of dry material, which means that all of the nutrients in the product will be preserved. Furthermore, it is possible to dry systematically if the supplied product varies in dry material content. This will result in a consistent end product. In the case of separated products, a pivoting belt places the product loosely on the smooth plates, so that the moist product can be transported to the dryer without having to be dried in advance. A part of the dried products is saved in the storage bin for mixing. The remaining dried product is transported to the final storage location. Dorset uses air channels to transport the air from the heat source to the dryer, and then from the dryer to the outside air. These channels are made of sandwich panels. The advantage of these panels is that they offer sufficient space for a calm air stream, thus minimizing dust formation. At the final storage location, the dried product can be pressed into pellets. Another option is to pack the product.
