  • Oil shale is not a viable fuel source - Study

    While many are celebrating the end of the 'Peak Oil' concerns because of abundent new sources of oil in shale deposits, a true accounting for all economic and environmental costs to exploit this energy source suggests it may not be a viable proposition at all. Scientists' best estimates of the Energy Return on Investment (EROI) of oil shale suggest it is very inefficient compared to conventional ...

  • Evaluation of fuel rod cladding failure during a loss-of-coolant accident

    This paper describes a methodology for the quantification of fuel rod cladding failure as a result of a Loss-of-Coolant Accident (LOCA). The methodology is based on external coupling of the RELAP5 code and the TRANSURANUS code. The thermohydraulic response of the unit to the accident is simulated by the RELAP5 code, providing initial and boundary conditions for the thermomechanical simulation by ...

  • Combating global warming via non-fossil fuel energy options

    Non-fossil fuel energy options can help reduce or eliminate the emissions of greenhouse gases and are needed to combat climate change. Three distinct ways in which non-fossil fuel options can be used in society are examined here: the capture/production of non-fossil fuel energy sources, their conversion into appropriate energy carriers and increased efficiency throughout the life cycle. ...

  • End-of-life Tires as an Alternative Fuel (TDF) in Cement Kilns: Now Easier than Ever!

    End-of-life tires are a challenging type of waste since they are difficult to shred and are expensive to treat and get rid of. However, tire derived fuel TDF is an extremely good alternative to the traditional fuels used in cement kilns, like oil, coal, and petroleum coke. The following blog presents a solution and explains how TDF can be used for heating cement kilns. ...

  • Mexico’s first commercial waste to energy facility to supply alternative fuel under agreement

    Mexico’s first Waste to Energy plant is up and running in Hermosillo, Sonora. The facility began to take shape two years ago, when total waste management specialist ...

  • What is RDF?

    "Refuse Derived Fuel" comes from Refuse Derived Fuel, literally: fuel from garbage. All kinds of garbage sorted, broken, eddy current in addition to aluminum, magnetic separation of iron, and then broken, wind selection, compression and drying processes made of solid form (cylindrical bar) fuel, referred to as RDF. RDF calorific value is 14595-20016 kJ / kg, much higher than coal (about 10870 kJ ...

  • Thermo dynamical assessment of the digestion process

    ABSTRACT Digestion of sludge was mostly seen as a stabilisation process prior to disposal or land application. During the last years there is an increased interest to use biogas as alternative energy source to replace the use of fossile fuels and giving the digestion process an economical value. In this paper a correlation is derived to combine the degradation of sludge with the amount of ...

  • RDF for cement kilns

    The use of the cement has significantly contributed to the worldwide economies. In fact cement is considered to be the second most consumed substance in our society and apparently the amount of it, used in construction, is more than double that of the total of all other building materials, including wood, steel, plastic and aluminium. Nowadays the cement industry has important environmental ...

  • UNTHA optimises WtE production and metal recycling at Turkish paper mill

    An UNTHA shredder is now fully operational in Turkey’s first solid waste incineration plant. The single step XR3000C has transformed Modern Enerji’s approach to metal recycling, at the same time as boosting the production of ...

  • Modelling performance of ultracapacitor arrays in hybrid electric vehicles

    This paper describes the development of a computer model to model performance of ultracapacitor arrays in hybrid electric vehicles. A Power-Based Model (PBM) was created and the results were compared with data from the University of Idaho's ultracapacitor hybrid Future Truck. The PBM accurately predicts vehicle fuel economy and allows quick simulation speed. This model includes a derived Internal ...

  • Hotter than Hungarian Salami – the new VR Series

    In Hungary, our existing customer Gepsystem needed a solution for refining the material pre-shredded by an XR2000 and thus increasing sales. Our newly developed VR Series proved to be the perfect solution. The company is now operating a VR120 and VR160 at full capacity and supplies a Hungarian cement plant with first grade refuse-derived fuels. One of the VR Series' numerous quality features ...

  • SRF – a class of its own

    Solid Recovered Fuel (SRF) is still classified as a waste material, not a product, despite the fact it is manufactured to a quality specification and is a resource from which energy can be recovered. Here, UNTHA UK’s alternative fuel production expert Marcus Brew considers the parameters within which SRF must be manufactured, before investigating the arguments for and against SRF being ...

  • Quality means money in shredding C&D and Industrial waste for RDF production

    A typical challenge in turning Construction and Demolition waste (C&D) and Industrial waste into high grade Refuse-Derived Fuel (RDF) is that elastic and stringy materials wrap around the rotor of the shredder. This causes hours of maintenance downtime weekly and has immediate effect on productivity. When using TANA Shark this has not been an issue for our customer Ekokem-TSJ Yrityspalvelut ...

  • The effect of surrounding temperature on liquefied petroleum gas behaviour during exhaustion process

    Liquefied petroleum gas (LPG) is considered to be a cleaner fuel because it has less impact on air quality. However, the potential benefit of LPG usage in domestic or residential sectors in Malaysia is hampered by LPG residue in cylinder. A few critical factors, such as LPG composition, exhaustion rate and surrounding temperature, have been identified to significantly contribute to the LPG ...

  • TR Series captures Irish market

    In the past year, we were able to achieve a prominent position on the Irish waste market: Following tough negotiations and numerous visits to reference sites, we could convince an Irish waste management company of our technology. The company put a post-shredder of the TR series into operation. Before that, our new customer operated a commercial-waste treatment plant with two shredders of a ...

  • Leveraging microgrids in waste-to-energy applications

    What do the waste-to-energy and real estate sectors have in common? In both, location is the key factor influencing the bottom line. Although waste-to-energy conversion technologies continue to improve their efficiency, energy will always be worth more when it is in the right location. With rising energy costs and increasing concern over electric power reliability and sustainability, the ...
