| description | The main aim of this study was to investigate and compare different methods for the extraction of forest fuel from environments close to an archipelago. The study was based on relevant literature and published reports as well as personal communications.
Forestry has traditionally been characterized by intense efforts to rationalize and mechanize the cutting technique used for timber and pulpwood. In line with the increasing importance of forestry, more concentrated efforts can be expected in the area of techniques and methods, especially for the above-mentioned product lines.
In Sweden, forestry is of major importance and the Swedish economy and standard of living have mainly been created based on the revenues generated from it. Thus, it is vital that Swedish forests are harvested in an efficient and responsible manner.
The demand for biofuel is growing and today accounts for 15% of total Swedish energy production, a share that will probably increase.
This study is based on three research questions, which are described under the heading of Aim. The results reveal that the most profitable method for handling forest fuel is the traditional one, which is also the most commonly used method in southern Sweden, namely the stockpiling of logs in a clearing by means of forwarders followed by splintering at the place from where they will be distributed.
Today, the high cost of barge transport required for the extraction of forest fuel in an archipelago environment renders such operations unprofitable. In this study, the EU subsidies available for the extraction of forest fuel in an archipelago environment have not been taken into account. However, even if such subsidies were to be included, it would still be difficult to achieve profitability. |

Mitt övergripande syfte med detta arbete var att undersöka och jämföra olika metoder vid uttag av GROT i skärgårdsnära miljö. Underlaget för mitt arbete har utgjorts av den litteratur och rapporter jag läst samt personliga kommentarer. Skogsbrukets historia har präglats av ett intensivt arbete med rationalisering och mekanisering av avverkningstekniken för sortimenten timmer och massaved. I takt med att skogsbränslets betydelse ökar bör vi förvänta oss en ökad satsning på tekniker och metoder också för det sortimentet. Skogsbruket har således en stor betydelse för Sverige. Intäkter från skogsbruket har till stor del byggt upp Sveriges ekonomi och välstånd. Därför är det viktigt att Sveriges skogar utnyttjas effektivt och ansvarsfullt. Efterfrågan på biobränsle ökar och idag står biobränslen för 15 % av den totala Svenska energiproduktionen och andelen kommer troligen att öka. I denna studie har jag utgått från tre stycken frågeställningar som jag har beskrivit under avsnittet syfte och frågeställningar. Studien visar att den mest lönsamma metoden att tillvarata GROT är den traditionella och likaledes den vanligaste metoden i södra Sverige. Det är att högar med skogsbränsle samlas ihop till vältor på hygget med skotare vidare att det senare flisas vid avlägget. Idag är pråmkostnaden som tillkommer vid skogsbränsleuttag i skärgården alldeles för hög för att det skall vara lönsamt att ta GROT. I denna studie har det inte tagits någon hänsyn till det EU stöd som kan sökas när det gäller att ta ut skogsbränsle i skärgårdsnära miljöer. Oavsett om vi skulle räkna med detta bidrag blir det svårt att få lönsamhet i det. SLU/Dept. of Forest Products 2006 L3 swe eng https://stud.epsilon.slu.se/11242/ |
