COASTAL Biogas Steering Group Meeting and Conference, 12-14 November 2019, Roskilde, Denmark

The second COASTAL Biogas Conference was held on 13 and 14 November 2019 in Roskilde, Denmark. Prior to that, on 12 November, project partners met for the third Steering Group Meeting (SGM) to plan and discuss upcoming activities and further implementation of the project. At the beginning of the conference the critical eutrophication state of the Baltic Sea and possibilities to improve the situation were introduced in the keynote speech by a representative of HELCOM (Baltic Marine Environment Protection Commission – Helsinki Commission). Subsequently, first results achieved in the COASTAL Biogas project were presented and partners from connected projects gave an insight into how they try to tackle the issue of cast seaweed. In the last session the regulations and management of digestate in Denmark, digestate processing options and policy work on digestate management of the European Biogas Association were made subject of discussion. The study tour on the next day led the participants to the beach at Køge Bay (see photo) and the Solrød biogas plant, where cast seaweed is already utilised as co-substrate for anaerobic digestion.

The date and venue of the next conference will be released very soon on this website.

COASTAL Biogas at the event “Küstenforum Klimaschutz und -anpassung mit Treibsel”, 21 October 2019, Travemünde, Germany

On 21 October 2019 COASTAL Biogas German project partners participated in the event “Küstenforum Klimaschutz und -anpassung mit Treibsel” (coastal forum about climate protection and adaption with beach wrack) in Travemünde, Germany. The event was hosted by the two projects POSIMA and CONTRA. It was a great opportunity to meet and connect with representatives from companies, research institutes, SMEs and administrative bodies, which all have a joint interest in beach wrack and cast seaweed and their utilisation opportunities. Beach wrack can be utilised in various ways, for example as substrate for composting or biogas facilities, for coastal protection, as bio based resource for building insulation or even for bio-char production. However, there are still a number of open questions, which were discussed: The legislative framework for seaweed collection and handling at some points is unclear and the utilisation of fresh or digested seaweed as fertiliser on agricultural land is highly regulated by the fertiliser ordinance. Furthermore, the application process for exemption is complicated and time-consuming. This makes it difficult for coastal municipalities to choose an appropriate utilisation possibility. Nevertheless, there are positive examples, where coastal municipalities team up with local farmers and consistently work through the whole process.
