Advanced Heat Pump Systems Using Urban Waste Heat “Sewage Heat”
Mitsubishi Heavy Industries Technical Review Vol. 52 No. 4 (December 2015) 80 Advanced Heat Pump Systems Using Urban Waste Heat “Sewage Heat” YOSHIE TOGANO*1 KENJI UEDA*2 YASUSHI HASEGAWA*3 JUN MIYAMOTO*1 TORU YAMAGUCHI*4 SEIJI SHIBUTANI*5 The application of heat pumps for hot water supply and heating systems is expected. Through this, the energy consumption of hot water supply and heating, which account for a substantial proportion of the total energy consumption in a building, will be reduced. The level of reduction can be dramatically increased by use of "sewage heat," which is part of waste heat in an urban area. So far, however, it has been difficult to determine whether sufficient technical or basic data available to widely use sewage heat exists. Therefore, demonstrations on the evaluation method for the potential of sewage heat in an urban area and the actual- equipment scale of verification using untreated sewage were conducted to understand the characteristics of sewage heat, and major technologies for use of sewage heat were developed. The technologies were applied to the system using sewage heat, and the system achieved a 29% reduction in the annual energy consumption and a 69% reduction in the running cost in the hot water system in lodging facilities compared to the conventional system using a boiler. The depreciation timespan of the difference in the initial cost between the conventional system and the heat pump system is about four years, and this system has an economically large advantage. In this report, the results obtained through the development and the demonstrations are systematically organized and the technical information needed for introduction of use of sewage heat is provided. -

However, it has not been previously shown explicitly which key parameters are most crucial, how much each parameter affects results and conclusions and how different aspects depend on each other. The interconnection between waste incineration and the energy system is elaborated by testing parameters potentially crucial to the result: design of the incineration plant, avoided energy generation, degree of efficiency, electricity efficiency in combined heat and power plants (CHP), avoided fuel, emission level of the avoided electricity generation and avoided waste management. CO2 emissions have been calculated for incineration of 1 kWh mixed combustible waste. The results indicate that one of the most important factors is the electricity efficiency in CHP plants in combination with the emission level of the avoided electricity generation. -

The Compelling Facts About Plastics 2009 an Analysis of European Plastics Production, Demand and Recovery for 2008
The Compelling Facts About Plastics 2009 An analysis of European plastics production, demand and recovery for 2008 1 2008 – At a glance Global production fell back in 2008 to 245 million tonnes from 260 in 2007 on the back of the financial crisis. The plastics industry experienced a dramatic 3rd and 4th quarter triggered by the economic crisis – more for those serving capital markets and less in daily consumables. Europe produced 60 million tonnes and remained a major region contributing about 25% of the global total. The plastics industry – plastic producers, converters and machine manufacturers – employed 1.6 million people and many times more in industries depending on plastics for their business. The plastics producers and converters also contributed together around 13 billion € in trade surplus to EU27 which helped to reduce the 242 billion € trade deficit for the whole industry in 2008. Demand by European converters fell back 7.5% to 48.5 million tonnes in 2008. Waste generation increased by just under 1%. Both recycling and energy recovery increased to drive total recovery rate for plastics to 51.3% and disposal at landfill down to 48.7% thereby opening up a gap of 2.6%. Recycling increased by 4.3% over 2007, a lower year-on-year increase than in recent years, reflecting the severe impact of the economic crisis on this sector. Energy recovery increased 3.6% over 2007. Seven of the EU Member States plus Norway and Switzerland recover more than 80% of their used plastics. These countries adopt an integrated resource management strategy using a range of complementary options to address each different waste stream with the best environmental and economic option. -
Improving Resource Efficency to Combat Marine Plastic Litter
Improving Resource Efficency to Combat Marine Plastic Litter Issue Brief Prepared by the OECD as input for the 2019 G20 Ministerial Meeting on Energy Transitions and Global Environment for Sustainable Growth January 2019 Organisation for Economic Co-operation and Development │ 2 1. Introduction 1.1. Persistent growth in resource use is creating widespread environmental damage: marine plastics litter is a prominent example 1. Recent decades have seen unprecedented growth in demand for natural resources and the materials derived from them. Around 80 billion tonnes of minerals, fossil fuels, and biomass were fed into the global economy in 2015 and, in the absence of policy action, this will increase with ongoing population growth and improving standards of living. Modelling undertaken by the OECD suggests that resource use will more than double by 2060 under business as usual.1 2. The extraction, use, and disposal of natural resources at these scales is creating significant environmental pressure, with serious consequences for ecosystem health, economic growth, and human well-being. Biodiversity loss and climate change are perhaps the two most high-profile examples. However, nowhere are the damages associated with rapidly growing material use more visible than in the case of plastics pollution, which is now ubiquitous across much of the Earth’s surface. Plastic is present in all the world’s ocean basins, including around remote islands, the poles and in the deep seas, and an additional 5 to 13 million tonnes are estimated to be introduced every year to the oceans.2 This material will only decompose over the course of hundreds, if not thousands, of years. -

Smitha, , John D. Aberb a University of New Hampshire Department of Natural Resources, 105 Main Street (Nesmith Hall 222), Durham, NH 03824, USA b University of New Hampshire Department of Natural Resources, 105 Main Street (Nesmith Hall 126), Durham, NH 03824, USA HIGHLIGHTS GRAPHICAL ABSTRACT • Energy recovery rates from a com- mercial-scale composting facility are presented. • Compost vapor between 51 and 66 °C resulted in recovery rates of 17,700–32,940 kJ/h. • Energy recovery was directly related to compost vapor and heat sink tem- peratures. • Temperature lag times between in- itiation of aeration and system equili- brium existed. • Temperature lag times warrant unique aeration schedules to maximize en- ergy recovery. ARTICLE INFO ABSTRACT Keywords: This study reports operational information from a commercial-scale Aerated Static Pile (ASP) composting system Compost energy recovery with energy recovery, one of the few currently in operation globally. A description of this innovative system is Aerated static pile composting followed by operational data on energy capture efficiency for 17 experimental trials with variable compost vapor Compost heat recovery and heat sink temperatures. Energy capture was directly and predictably related to the differential between Alternative energy compost vapor and heat sink temperatures, with energy capture ranging from 17,700 to 32,940 kJ/h with a Waste to energy compost vapor temperature range of 51–66 °C. A 5-day temperature lag time existed between compost pile formation, and when compost vapor temperatures were sufficiently high for energy recovery (≥50 °C). -
Playing to One's Strengths
ISSUE 29 Quarterly Journal - December 2018 NEWS COMMENT and ANALYSIS on SPINOUTS from UK HEIs Playing to one’s strengths As we have frequently remarked, and as the figures given in our Quarterly Journals demonstrate, spinout activity—new spinouts created, investment, exits - is highly concentrated in the South East of England. While universities such as Oxford and Cambridge, Imperial and UCL, go from strength to strength, making the most of their favourable environment - business, technology, investment - outside the ‘golden triangle’ it is not possible for universities to replicate the same conditions, and they must identify their own strengths and put them to maximum effect. We have two examples in this issue: Univeresity of Birmingham Enterprise’s account of the commercialisation collaboration between eight Midlands universities (p17), and our Spotlight feature on Swansea University (p15), which has evolved a technology transfer model tailored specifically to its own circumstances. Encouragingly, the Knowledge Exchange Framework (KEF) currently under development acknowledges this issue, and has set out to group universities in clusters, so that universities in the most favoured environments can be assessed against their peers, and others judged by criteria more relevant to their own environments; see our report on p13. Since the publication of our previous Quarterly Journal, the sale of Spinouts UK to Beauhurst has been completed. Henry Whorwood of Beauhurst explains what this means in terms of tracking and profiling spinout companies on p8. There will be a transitional handover period, with Spinouts UK founder and editor Jonathan Harris continuing to produce the Quarterly Journals, while Beauhurst gradually takes over the data collection activities. -

The main objective of this study is to track the 18 global transport of e-wastes by compiling and constraining existing estimates of the amount of e-waste 19 generated domestically in each country MGEN, exported from countries belonging to the Organization for 20 Economic Cooperation and Development (OECD) MEXP, and imported in countries outside of the OECD 21 MIMP. Reference year is 2005 and all estimates are given with an uncertainty range. Estimates of MGEN 22 obtained by apportioning a global total of ~35,000 kt (range 20,000-50,000 kt) based on a nation’s gross 23 domestic product agree well with independent estimates of MGEN for individual countries.
