    Sammanfattning : Wind turbines have been utilized for centuries to harness energy from the wind. Commercial wind turbine blades are typically made from composite materials, which are difficult to recycle, leading to blades ending up in landfills at the end of their lifecycle. Additionally, these materials contribute to microplastic pollution. LÄS MER

    Sammanfattning : Phenology is the study of the timing of natural events such as leaf-out, bud burst and senescence relative to climate change. It is important to understand how the climate change will affect the timing of these events as it in turn affects the carbon-, nutrient- and the hydrological cycles. LÄS MER
