Biochemical methane potential of microscopic and macroscopic algae of the Baltic Sea and the effect of pre-treatment on biomass efficiency

Water issue adressed: Too much
Piles of polluting algae biomass on the coast of Baltic Sea

As the modern demand for energy resources grows along with the depletion of fossil resources and the need to take care of our environment, so grows the incentive to focus on long term growth and development.It can be expected that in Latvia the production of biogas and its multiple uses especially in terms of producing energy will continue growing. As it has been the case over the last 15 years in multiple countries within the European Union as well as elsewhere in teh world. It is produced from biodegradable domestic residue, byproducts of farming, byproducts of food production and from plants grown for this specific purpose.In Latvia there is potential for the use of the algea biomass that is currently polluting our shores.For example, the gathering of algea one the beaches of Liepaja for usage is a simple and cheap process due to the sandy and uncluttered beach. There is also a possibility to produce algea cultures within fotobioreactors. Therefore there is growing interest in more effective usage of available resources and producing biogas, while cleaning up the shores of the Baltic sea.

Project topic:The biochemical methane potential of microscopic and macroscopic algea from the Baltic sea and the effect of preprocessing on the effectivity of the biomass.

Project question:Does preprocessing affect the biochemical potential of algea?

Project goal: To determine the connection between biochemical methane potential, type of algea and preprocessing.

This is how I came up with the idea for this project:

On the Baltic Sea shoreline, tons of algae are washed out annually. Despite Latvia investing resources in maintaining its shoreline, algae makes beaches less attractive due to restricting water access and emanating unpleasant odors. Algae is used in the production of compost, but there are alternatives for making coastline clean.
