  2. 1. Life cycle assessment of renewable-based hydrocarbon plastics

    Author : Christin Liptow; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; renewable LDPE; biomass-based plastics; simplified LCA for conventional; LCA and process simulation;

    Abstract : Plastics are an important commodity of our daily life. And although their majority is still based on fossil feedstocks, numerous efforts are made to stem the environmental consequences related to their production. One approach is the use of renewable materials (biomass) to produce today’s conventional plastics. READ MORE

  4. 2. ALTERNATIVE POLYETHYLENE CROSSLINKING CONCEPTS FOR POWER CABLE INSULATION

    Author : Massimiliano Mauri; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epoxy; crosslinking; HVDC; polymer blends; click-chemistry; polyethylene; Renewable Energy; High-voltage insulation;

    Abstract : We currently witness an accelerating shift from fossil energy sources to renewables driven by the urgent need to reduce carbon emissions. Wind, solar and hydro power is most abundant in places far away from the end user, which necessitates the efficient transport of electricity over long distances. READ MORE

  5. 3. Novel Thermoplastic Material Concepts for High Voltage Cable Insulation - Engineering Immiscible Blends for a Sustainable Future

    Abstract : To cope with our growing demand for energy in a sustainable way, efficient long-distance power transmission via high voltage direct current (HVDC) cables is crucial – these cables facilitate the integration of renewable energy into our power networks. For reliable and efficient power transmission, underground and undersea cables require robust insulation materials that possess a high level of mechanical integrity, a low direct-current (DC) electrical conductivity and a high thermal conductivity at the elevated temperatures experienced during cable operation.
