  1. 1. Life cycle assessment of hybrid systems for rural electrification in Bolivia

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Sandu Seres; [2021]
    Keywords : Diesel; Stirling; Photovoltaic; impact category;

    Abstract : Bolivia is a developing country in South America. Many rural communities still lack access to electricity. The extension of the National Grid System to all rural communities is not feasible due to economic and topographic challenges as well as the environmental problems that may arise. To tackle these problems, Off-grid solutions are implemented. READ MORE

    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.
