  • Addressing food waste through anaerobic digestion

    Food waste continues to be a problem worldwide, even with more and more attention being paid to reducing spoilage and to salvaging edible foods for redistribution or reuse. One approach to the problem is diverting inedible organic matter from landfills and treating it with anaerobic digestion, which has the side effect of capturing energy. The amount of food wasted worldwide was 2.3 billion ...

  • Is waste heat the silver bullet?

    The energy industry tends to get stuck on certain words. Silver bullet is one of them. Insiders and policymakers often like to say there is no silver bullet to fix US energy woes. We need a portfolio of solutions – renewables, efficiency, smart grid, transmission expansion, coal sequestration, etc. That may be true, but Tom Casten begs to differ. Casten is a bit of a rock star in the field of ...

  • Exergy or the entropic drive: waste heat and free heat

    The dissipation of exergy is conventionally held to be the inference of the entropy growth. In this conventional perspective, the universe is running down towards equilibrium or heat death. Recent cosmological findings of 1998–2000 give empirical evidence that the universe is instead moving away from equilibrium while its entropy increases. We can better comprehend this non–equilibrium world by ...

  • Recycling industrial waste heat for sustainable district heating: a multi-actor perspective

    Addressing the climate change and energy scarcity problems are two of the most complex sustainability challenges facing not only scientists, but also policy makers. Attempts at tackling these issues should be approached from two fronts: by increasing the energy efficiency (demand side) and by promoting the usage of renewables and non-Greenhouse Gases emitting energy sources (supply side). ...

  • Case study - Waste heat generates steam and savings

    OVERVIEW A coil coating facility purchased a new a 15,000 SCFM Regenerative Thermal Oxidizer (RTO) which had a nominal heat transfer efficiency rate of 90% thermal energy recovery. It was designed with supplemental fuel injection (SFI) which is used during low VOC loading conditions, to help save fuel cost.  The facility was looking for additional ways to decrease their exhaust ...

  • WEISS provides for the heat - and disposes of the waste case study

    The very first time PLIMOB learnt about Weiss was in 1995 at which time contacts at IKEA told about combustion plants from WEISS. IKEA is the most important customer for PLIMOB so the management listened to the recommendations. PLIMOB is producing wood furniture; large quantities of wood chips and sawdust are a spin-off effect from their production. Traditionally wood-working industries – ...

  • Seawater desalination utilising waste heat by low-temperature evaporation

    Utilisation of waste heat is one of the ecofriendly ways to produce low-cost desalted water. Keeping this in mind, Low-Temperature Evaporation (LTE) desalination technology utilising low-quality waste heat in the form of hot water (as low as 50?C) or low-pressure steam (0.13 bar) has been developed to produce high-purity water (conductivity ...

  • Thermodynamic and exergy efficiencies of magnetocaloric energy conversion utilising industrial waste heat

    An investigation under which conditions industrial waste heat utilised with magnetic energy conversion machines can be a possible alternative to conventional energy conversion technologies is presented. The application of a numerical model leads to the thermodynamic efficiency, the exergy efficiency, and approximate values of the total mass and the total volume of a magnetic energy conversion ...

  • Nuclear desalination by waste heat utilisation in an advanced heavy water reactor

    The use of thorium for nuclear power generation is an important element of the Indian atomic energy programme. The design and development of the Advanced Heavy Water Reactor (AHWR) is a step in this direction. Intensive design activity is underway to set up a 300-MWe AHWR. The design of the AHWR incorporates several features to simplify the design and to eliminate certain systems and components, ...

  • How to recuperate industrial waste heat beyond time and space

    Any fossil fuel energy, after industrial utilisation such as combustion and electric generation, is finally emitted in the form of waste heat to the atmosphere. A database on waste heat revealed that a large amount of energy can be saved by reusing the high-temperature industrial waste heat efficiently. Thus, this paper introduces cutting-edge technologies for heat recovery by three promising ...

  • Case-study - Utilising waste heat for water production and climate control

    Water purification is needed to produce high quality water for consumption, agriculture and industrial needs. Conventional water treatment processes, like distillation and reverse osmosis, consume vast amounts of energy. However, there is a large potential for significant reductions in energy consumption and CO2 emissions in this sector. It can be achieved by the exploitation of waste heat for ...

  • Heat Pumps – FAQs

    1. What is a Heat Pump? To put it simply; ground source heat pumps and geothermal heat pumps produce high grade heat from low grade heat which is found in the earth and our atmosphere.2. How does a Heat Pump Work?Heat pumps work in exactly the same way as air conditioners or refrigerators, but in reverse! Heat pumps capture latent energy which is stored in sources such as air, water and earth. ...


  • Combined Heat and Power (CHP) essentials

    'CHP essentials' introduces the concept of power and heat 'production possibility sets', starting at the cradle of CHP, i.e., the thermal power generation plant. The latter always occasions 'fatal' heat that is either recovered (the 'merit' of CHP) or wasted (condensing). This split paves the way to defining the production possibility sets of CHP plants, shown for steam turbines, internal ...

  • Women in waste

    The current climate can not be described as prosperous whatever the profession that you are in. It is not a way of ‘living’ but merely a means of ‘surviving’. This has never been more accurate than for the women in waste. The name Jane is defined as one of the many feminine forms of John whereas John is defined as an English masculine name. In the workplace in many industries today, focussing on ...


  • Oxidation characteristics of A588 steel and its applicability to high-heat-load nuclear waste package designs

    The ASTM A588 steel is proposed as the outer wall material for second-generation nuclear waste package designs (Armijo et al., 2006; Kar, 2006). Oxidation weight-gain kinetics was evaluated for the A588 steel by thermal-gravimetric method at a range of temperatures (475°C to 600°C). Isothermal oxidation tests were conducted in dry air. Oxidation at lower temperatures followed parabolic kinetics ...
