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

   Author : Anna Bernstad; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste management; household waste; food waste; life-cycle assessment; anaerobic digestion; systems analysis;

   Abstract : 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).

   Abstract : The history of wastewater management tells us that efforts have been made at solving only one problem at the time; sanitation during the first half of the 20th Century followed by eutrophication of lakes and sea and, for the past ten years, recycling of nutrients. After the "Brundtland Report", 1987, a reversal of the debate occurred where water management was discussed in a more holistic manner than before. READ MORE
