1. 1. Beach-cast fertilizers for cultivation of carrots and radishes on Swedish Gotland : The effect on crop size and nutrient composition

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Sofie Ögren; [2020]
   Keywords : Eutrophication; marine biofertilizer; beach-cast management; nutrient analysis; NMR;

   Abstract : In the eutrophicated Baltic, algal blooms with toxin-producing algae and plant overgrowth is a large threat to the marine environment, humans and animals. The use of external nutrient inputs into agriculture, such as mineral fertilizers (NPK), is reaching the Baltic through runoff which causes a constant, linear nutrient flow from land to the sea, which is one of the main contributors to accelerated eutrophication.

3. 2. Utilizing beach-cast seaweed for biochar production in Gotland : A study of energy and carbon balances of algal biochar

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Johanna Sörbom; [2020]
   Keywords : ;

   Abstract : With global warming, rising environmental issues, and increased beach-cast production, climate change mitigation efforts are important for the future of the planet. Carbon dioxide removal technologies are now deemed essential to reach the Sustainable development goals and keep the temperature rise under 1.5 or 2 degrees °C. READ MORE

4. 3. Harvesting and utilizing beach cast on Gotland : A study of the benefits, challenges and opportunities of turning a waste into a resource

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Filip Dessle; [2017]
   Keywords : Beach cast; macroalgae; bioenergy; biofertilizer; eutrophication; cadmium;

   Abstract : Accumulation of beach cast biomass on coastal zones around Gotland is an increasing problem that reduce the recreational value of beaches and cause environmental degradation of coastal environments. Beach cast was once regularly harvested on Gotland, as it was considered a valued biofertilizer, but as it seized to be used in combination with the eutrophication of the Baltic sea, beach cast accumulation has increased in scale.

5. 4. Bioenergy production from beach-cast macro algae : The West Coast of Sweden

   University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

   Author : Meaza Tadesse Yohannes; [2015]
   Keywords : eutrophication; beach cast macro algae; cadmium; cadmium removal; energy extraction; anaerobic digestion; combustion; incineration; energy balance analysis;

   Abstract : Excessive algae growth/ bloom has become a commonly observed phenomenon in many water bodies globally due to eutrophication. This phenomenon has also been observed in the Baltic Sea which create nuisance in many Baltic coastal communities when the macro algae of different species is washed ashore by wind and wave, which is known as “beach cast algae”.

6. 5. Impact of Using Macroalgae from the Baltic Sea in Biogas Production : A Review with Special Emphasis on Heavy Metals

   University essay from Linnéuniversitetet/Institutionen för naturvetenskap, NV

   Author : Kristofer Bergström; [2012]
   Keywords : biogas; macroalgae; heavymetals; Trelleborg;

   Abstract : A consequence of eutrophication in the Baltic Sea is growth of algae that accumulates in the coastal areas and beaches. Dense algal mats may cause anoxia or hypoxia and greatly reduce the recreational value of the area. Algae also functions as hyper accumulators of heavy metals and their metal levels may become toxic to higher trophic levels. READ MORE
