FUELS

EFO is one of the major importer of solid fuels, for the purpose of heat and power generation, for our customers in Sweden with an approximate total annually tonnage of 750 000 of different quality fuels

Historic import volumes (metric ton)


Recycled Fuels

Energy from Waste plays an important role in the circular economy, as energy out of waste residues can efficiently be recovered for production of both heat and power in a combined cycle. By incinerating the waste in our customers CHP plants (Combined Heat and Power) the waste becomes an asset and with this we avoid waste to landfill and create a win for both the environment and EFO’s customers in Sweden where waste are scars

 

 

Waste Fuels

Waste fuels originates from municipal household waste, industrial, commercial or waste from construction and demolition.

Waste are categorized as Refuse Derived Fuel (RDF) containing, both wet and dry matter, or Solid Recovered Fuel (SRF) consisting dry matter only. RDF normally comes from waste residue which is too difficult or too complex to recycle and depending on what recycling measures a specific municipality have taken, it can be either with or without organic material. As the waste is collected it’s delivered to a processing facility where it through a number of processing steps is turned into an RDF. Typically these steps include sorting shredding and screening, sorting for collection of metals and some plastics suitable for recycling, shredding for more homogeny size distribution and screening to get rid of inert material such as glass and stones etc. The final product is compressed to a bale and wrapped with plastic for transportation to our customers. The SRF normally comes from industrial, commercial or construction waste, typically containing plastics, paper, and some waste wood. The industrial or commercial waste is collected and delivered to a processing facility. The SRF, in a way similar to the RDF, is sorted, shredded, screened and undergoes metallic separation prior to being compacted and wrapped to a bale for transport.

Solid Biofuels

Energy from solid biofuels have historically been the alternative for fossil free heat and power generation in Sweden and was introduced large scale in the 1990 tees, through incentive schemes with the aim to abandon traditional fossil fuels. What boiler type installed at a specific power plant, constitutes different demand for solid biofuels, which can be sourced as wood chips from forest residues, wood chips from round wood, bark, or sawdust either as lose material or as pellets. Typically if a power plant is purpose built for biofuels it will run on the lower quality fuels, being woodchips from forest residues. And vice versa if the power plant is converted from running on fossil fuels to bio fuels it will need higher quality fuels being wood pellets or saw dust

  

  

Wood Chips from forest residues (Hog Fuel)

As result of forest processing activities tree branches and tree tops becomes a byproduct when producing round wood. The residue have little value and will either be left in the forest or can alternatively be turned into a fuel through a process of crushing the material into finer size. If and when the residue becomes a fuel is determined by traditional market conditions i.e. if the fuel can find a demand nearby. Because of the low value of the product logistics cost can rapidly become 60% of the total value of the product and if exceeded it becomes too expensive and it will then be left in the forest

 

 

Wood chips from round wood

Round wood that for some reason do not meet the requirements of either the pulp or the sawmill industries can be sourced as solid biofuels. This requires the round wood to be cut into woodchips which is done either at the power plants facility or prior delivery to the plant. The supply of round wood is subject to normal market conditions where pulp, sawmill and MDF board industries have a higher paying capability, hence if those industries have little demand it constitutes possible supply for the energy sector
