Biomass  from  wetlands  has  historically  been  an  important  resource,  but  today  it  is  difficult  to  take advantage  of  this  biomass,  besides  being  used  as  feed  on  the  farm.  A  very  important  goal  is  to  find rational  and  economical  viable  way  to  make  biogas  from  wetland  biomass,  including  biomass  from other   conservation   worthy   areas   of   high   biodiversity,   such   as   roadsides   harvested   frequently. Moreover,  the  residues  from  biogas  process  used  as  bio-fertilizer  to  the  fields,  so  that  nitrogen  and phosphorus is returned to the farm land. The biomass can be used for the production of biogas or for extracting valuable chemicals in bio refineries. These valuable chemicals may be potentially useful for making future plastic materials, i.e. bio plastics. Major focus will be on biogas technology, and above all, methods for the pretreatment of recalcitrant substrates such as biomass containing high levels of lignocelluloses, i.e., to make the material available to the biogas-producing bacteria. The work is based on  an  involvement  of  research  in  the  areas  of  environmental  engineering  and  landscape  science  and includes studies of biodiversity and water treatment function of the landscape.  Finally, it is important to stress that mowing of wet meadows mostly will result in a better capacity of such meadows to retain nutrients from water passing through them. Wetland with wet meadows and similar vegetation types will be more efficient in cleaning water and thereby fight eutrophication in the recipient. Summing up, the  main  advantages  using  harvest  hay  (mowing)  from  wet  meadows  and  roadside  meadows  as substrate for biotechnical industry are:

•Raw material for bio plastics

•Cheap and easy handled fertilizers to agriculture

•Important for biodiversity

•Better function of wetlands as nutrient traps fighting eutrophication of the sea
