    Sammanfattning : Organic chemists have the ability to create complex organic molecules by connecting molecular building blocks in different ways. To name a few, these molecules are used as medicines, pesticides or in our household electronics, and are therefore crucial to life as we know it. LÄS MER

  4. 13. Household food waste management – Evaluations of current status and potential improvements using life-cycle assessment methodology

    Författare :Anna Bernstad; Avdelningen för kemiteknik; []

    Sammanfattning : An increased understanding of the world’s limited resources and the negative environmental impacts connected to solid waste management has in recent years increased interest in separate collection and treatment of organic waste in many parts of the world. As an example, increased biological treatment of organic waste is an explicit goal within the Swedish national solid waste management strategy (SEPA, 2006) and the national environmental objectives state that 35% of all organic household waste should be treated biologically by 2010 (SEPA, 2007).
