  1. 1. Pressurized Fluid Extraction : A Sustainable Technique with Added Values

    Author : Monica Waldebäck; Karin Markides; Åke Bergman; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; ASE; biomass; green chemistry; household waste; lipid; pesticide; PFE; pressurized fluid extraction; sediment; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : The challenge for the future was defined by the Brundtland Commission (1987) and by the Rio Declaration (1992), in which the fundamental principles for achieving a sustainable development were provided. Sustainable chemistry can be defined as the contribution of chemistry to the implementation of the Rio Declaration. READ MORE

  2. 2. Industrial energy efficiency improvement – the role of policy and evaluation

    Author : Christian Stenqvist; Miljö- och energisystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement.; Pulp and paper; Decarbonisation; EU ETS; Energy management; Voluntary Agreement; Evaluation; Policy; Industrial energy efficiency;

    Abstract : At EU and to a varying degree at Member State (MS) level, industrial energy efficiency improvement (EEI) is considered an attractive means for reaching political objectives of different dimensions, not least environmental. For energy-intensive manufacturing industry in particular, EEI can lead to cost reductions, improved profitability and competitiveness. READ MORE
