    Abstract : The direct variable costs for heat and electricity production based on solid biomass fuel combustion is approximately 3-5 times lower than the costs in a fossil fuel-oil based boiler in Sweden. In addition waste derived biomass fuels are typically much cheaper than biomass not classified as waste. READ MORE

  4. 17. Residues from biochemical production of transport biofuels in Northern Europe : combustion properties and applications

    Author : Gunnar Eriksson; Bengt Johan Skrifvars; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Residues from biochemical production of liquid transport biofuels will probably become available for energy use if more gasoline and diesel is substituted. For processes used in northern Europe they amount to 35-65 % of the feedstock energy and despite interest from energy companies, their fuel properties are largely unknown. READ MORE

    Abstract : Shortage of food is an alarming problem today, with up to 821 million people that are undernourished world-wide. At the same time, enough edible foodstuff to feed 1.9 billion people are wasted or lost in the food supply chain that for aesthetic reasons, handling and transportation inadequacies in the food supply chain and lack of market.

    Abstract : Fossil based energy resources are dominating the world’s primary energy consumption for the last century. However, with decreasing crude oil reservoirs and the role they play in global warming by emitting greenhouse gases, the focus has been turned towards improved utilization of renewable resources and the need for new, sustainable fuels and chemicals is more urgent than ever.
