Opis:
Beach wrack is a unique issue. It is both an ecological problem for the eutrophicated reservoirs such as the Baltic Sea and the social one associated with nuisance for inhabitants and tourists visiting seaside resorts. This generates a problem for the institutions responsible for beach management (local authorities). Nowadays local authorities generally leave cleaning the beach to local companies and it is not known how the beach wrack material is utilized. According to the current trend, the nuisance of beach wrack should be turned into a resource that will bring benefits. In order to understand what beach wrack really is, it is necessary to establish a specific definition. The material washed out by the sea contains not only the natural substances of organic origin, but also human products: plastics, glass or metals, which in many cases forces to pre-select before using the technology. Good treatment of material the quantities of which are undefined and the occurrence is variable, constitutes a real challenge. The beach wrack processing on reed bed system, so far used mainly for the treatment of sewage sludge, seems to be a good idea. It is an innovative technology that is expected to have similar results as for the processing of sewage sludge from wastewater treatment, i.e. a high nutrient fertilizer. In accordance with European Union recommendations, the possible use of beach wrack as a fertilizer in agriculture or enrichment of compost, will close the circulation of organic matter in environment, thus entering the reed bed system into a circular economy. Many aspects related to the reed bed system favor the use of this technology in the practical processing of marine organic waste.

Opis:
This paper evaluates the second part of a three-year field study to investigate the effects of the beach macro- and meiofauna community structure on the decay of stranded wrack on Hel Beach (see Jędrzejczak 2002),f ocusing on successional changes and the colonisation of wrack by beach fauna. The investigation enabled the associated faunal assemblages to be characterised. Zostera marina tissue was colonised by the supralittoral fauna in two distinct phases. The macrofauna, including the talitrid amphipod Talitrus saltator,ad ult Diptera and Coleoptera, colonised the wrack within a day,with maximum numbers being recorded after 3 days. Thereafter,their numbers in the samples declined and the meiofauna, consisting of nematodes, oligochaetes,tur bellarians and dipteran larvae, became increasingly abundant. After 18 days,the wrack surface was dominated by meiofauna. This faunal succession was not directly related to the degradation of the seagrass tissue,whic h proceeded linearly throughout the study period. Exclusion of macrofauna from the wrack by the use of < 1 mm mesh litterbags had no appreciable effect on the rate of dry matter loss. Therefore,the major macrofaunal wrack consumers,including T. saltator and Coleoptera,d id not affect the rate of seagrass disintegration. The effect of meiofaunal nematodes, oligochaetes,gast rotrichs and turbellarians on wrack breakdown could not be accurately determined. However,the development of the meiofaunal community suggested that changes in the fauna community were linked more closely to successional changes in the chemistry and/or microflora of the beach wrack than to its physical breakdown.

Opis:
The effects of the beach community structure of macro- and meiofauna on the process of beach wrack decay were investigated by means of a simple field colonisation experiment in a temperate, fine quartz sediment, sandy beach at the end of the Hel Peninsula in Poland. 1260 replicate litterbags of three mesh sizes (12 mm, 0.5 mm, 48 μm) containing fresh wrack were used to assess the role of faunal and non-faunal components in the breakdown of stranded Zostera marina. Wrack breakdown was determined during a three-year field study. This paper presents the first part of the results of this field experiment, which refer to the effects of fragmentation detritivory, leaching and decay rates. Material was lost from the bags at a rapid rate, with only 22–32% of the original dry mass remaining after 27 days in the field. This degradation was not directly related to the faunal succession of the eelgrass tissue, which proceeded in two distinct phases throughout the study period. Exclusion of macrofauna from the wrack by the use of finer-mesh litterbags (< 1 mm) had no appreciable effect on the rate of dry matter loss. Microbial decay, and abiotic leaching and fragmentation are probably the major causes of seagrass weight loss from the litterbags.
