  • Bio4Energy Environment and Nutrient Recycling

    environmental_600Scientists on the platform Bio4Energy Environment and Nutrient Recycling perform research with the aim to render waste products or surplus energy from biorefinery useful for other processes, or to check the efficiency and sustainability of products or processes over their life cycle.

    Researchers on the platform Bio4Energy Environment and Nutrient Recycling have set out to provide the checks and balances in the work of the overall research programme to create environmentally-sound and sustainable biorefinery processes. These should be made to operate efficiently and turn out energy-efficient products, as well as cause or produce no or only a minimum of environmental pollutants and undesirable by-products or waste.

    General objectives are:

    • To contribute to the development of environmentally-sound and sustainable forest-based biochemical and thermochemical industrial processes;

    • That the ecological footprint in terms of emissions of substances that are hazardous to soil, water and atmosphere should be minimised and;

    • That complete biomass use loops should be created.

    Specific goals include:

    • The recovery and purification of nutrients from waste streams. Deeper understanding of the impact of recycling various nutrient/ash mineral assemblies on soil chemistry and plant availability;
    • The generation of value-added products from waste streams: Adaptation of an algae satellite loop to a pulp-and-paper process environment;
    • Understanding the role of particulate matter from flue gas for the formation of persistent organic pollutants (POPs) in thermal conversion processes;
    • The minimisation of gaseous and particulate inorganic and organic hazardous emissions from thermal conversion processes and;
    • The revision of existing and future biochemical and thermochemical conversion processes to identify potential environmentally harmful impacts and incomplete use loops.

  • Bio4Energy-funded Projects Promoting Excellence, Collaboration Focus of Event

    Audience 210518 2 420Twice a year, the Bio4Energy scientists meet as a group to exchange ideas. Photo by Bio4Energy (archives).Bio4Energy offers its scientists the possibility to apply for so-called Strategic Funds to finance projects on new lines of research that are likely to advance the frontiers of science. The projects also have to promote collaboration between researchers from different disciplines or organisations; including universities, institutes and industry tied to the research environment.

    Today’s Bio4Energy Researchers’ Meeting, a biannual event for the research programme within the environment, learnt about projects enabled by those funds.

  • Conference on the Impact of Fuel Quality on Power Production and the Environment

    Call for papers - 28th International Conference Impacts of Fuel Quality on Power Production and the Environment

    cropped Final Logo
    When: Postponed until late September 2021

    Where: Åre, Sweden


    This conference, 28th in the series, will highlight solutions to the significant fuel-quality challenges facing power producers using current power technologies such as fluidised bed, sub-critical boilers, incineration, as well as newer technologies such as IGCC, PFBC, super- and ultra-super-critical boilers, oxy-fuel systems and gasifiers. These challenges involve fuel preparation and blending, slagging, fouling, corrosion, aerosol formation, ash disposal, catalyst poisoning, availability and capacity, as well as sensors and control strategies.

    The conference emphasises end-results and application of fundamental information to minimise fuel quality impacts on power
    production and the environment. The conference will focus on traditional fuels, particularly traded coals, low-grade and low-rank coals and opportunity fuels such as biomass, tires, black liquor, MSW, waste sludge and pet coke. Fundamental studies, pilot-scale investigations, full-scale evaluations and computer simulation papers are encouraged.

    Sessions for the conference will include, but are not limited toBio4energy cmyk

Photo by Bio4Energy© 2020.Scientists in Bio4Energy have taken a decisive step in a multi-actor project to provide sustainable bioenergy solutions for people in some of the least well-off countries in Africa, by designing a pilot installation that will produce energy-rich gas and biochar from pre-treated biomass residues.

    The construction of the two-metre tall pilot—which is still a miniature version of what a future commercial-scale gasification reactor would look like—is a collaboration between Bio4Energy researchers at Umeå University and at the Swedish University of Agricultural Sciences at Umeå, Sweden.

Photo collage by courtesy of Luleå University of Technology.Two of the partner universities in the research environment Bio4Energy are launching major initiatives to make researchers from different disciplines collaborate with each other and with industry to make northern Sweden lead the way in adapting to and countering climate change, in line with the United Nations’ Sustainable Development Goals (UN SDGs).

    Luleå University of Technology (LTU) in northernmost part of Sweden takes aim at basic industry in the region—sectors that draw on forest trees, mining ore or dams or waterfalls for hydropower—to carry out the transition to a sustainable economy.

    “Meeting the climate [change] goals and transforming basic industry requires an increased use of northern Sweden’s natural resources. We need new technology and new methods; new products and new solutions for fossil-free electrification, energy storage, efficient use of raw materials and use of byproducts”, said a press release from LTU.

    “Industry’s transition is going to require a great number of skilled people. We need to create attractive conditions for them to come here”, according to Söderholm.
