  2. 1. Virtual Mobility and Pollution Prevention - The Emerging Role of ICT Based Communication in Organisations and its Impact on Travel

    Author : Peter Arnfalk; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; pollution control; Environmental technology; travel reduction; pollution prevention; telework; web-meetings; audioconferencing; videoconferencing; virtual mobility; virtual communication; IT; IKT; ICT; Miljöteknik; kontroll av utsläpp; Informatics; systems theory; Informatik; systemteori; Telecommunication engineering; Telekommunikationsteknik;

    Abstract : Information and Communication Technologies change the way we work and communicate, enabling us to telework and to have virtual meetings - collaborating without a physical meeting. This can influence the need for commuting and business travel by provision of access to an activity without mobility - virtual mobility. READ MORE

    Abstract : Preventative environmental approaches (e.g. Cleaner Production and Pollution Prevention) have been successfully implemented in the manufacturing industry. They are, however, far from being fully adopted by all society actors. READ MORE

  5. 3. Sources and fate of plastic particles in northern European coastal waters

    Author : Therese Karlsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; plastic pollution; microplastics; method development; polyethylene; FTIR spectroscopy;

    Abstract : Plastics are integral parts of our lives and have allowed for important technological leaps within society. However, an unwanted consequence of our current consumption of plas-tics is marine plastic pollution and in order to reduce its impact we need to understand its sources and fate patterns. READ MORE

    Abstract : Biomass is considered to be a sustainable energy source with significant potentials for replacing electricity and fossil fuels, not at least in the residential sector. However, present wood combustion is a major source of ambient concentrations of hydrocarbons (e.g. READ MORE

  7. 5. Enhanced Biological Phosphorus Removal -Processes, Competing Substances and Tools for Operation of Wastewater Treatment Plants

    Author : Eva Tykesson; Vattenförsörjnings- och avloppsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; pollution control; Environmental technology; chemical precipitation; glycogen accumulating organisms; polyphosphate accumulating organisms; wastewater treatment; biological phosphorus removal; kontroll av utsläpp;

    Abstract : The idea of phosphorus removal at wastewater treatment plants is to transfer dissolved phosphorus into a solid phase. Together with the rest of the produced sludge it is then removed from the water, resulting in a decreased concentration of phosphorus in the effluent and the prevention of the eutrophication in the recipient.
