Landfill mining option: MBT role and landfill potential danger
The use of landfills for the disposal of municipal solid waste (MSW) has many technical and regulatory limits. An interesting solution is to recover the bales that have been previously stored in a landfill. After specific mechanical biological treatments (MBT), the contents of the bales can be used to produce a solid recovered fuel (SRF) that can be used for energy purposes. The possibility of producing SRF fuels from a landfill in northern Italy has been studied and is presented in this paper. The MSW extracted from the landfill, the bio-dried material produced by the waste hypothetically treated in a plant for bio-drying, and the SRF obtained after the extraction of inert materials, metals and glass from the bio-dried material have been characterized. Assessed the waste nature, the potential environmental impact of dioxin release from a possible landfill fire has been analysed, applying the Austal2000 model system.
Paradigm Shift in the British Waste Management Sector – from Landfilling to Incineration –
Twenty years ago, in 1994, the UK was still coming to terms with the advent of new legislation, principally the Environmental Protection Act 1990, under which many local government waste management operations were transferred to arm’s length companies, some of which were subsequently wholly or partly privatized. Other operations were the subject of public tenders in which the private sector to part. The author was involved in one of the first privately funded and operated energy from waste projects for Hampshire County Council, being a 400,000 tpa facility planned for Portsmouth.
Old landfills: Anthropogenic resources or reserves?
The overall objective of this study is to apply a primary resource classification framework to a landfill mining project in order to identify the whole landfill and its contained materials either as anthropogenic resources or reserves.
Innovative Design of Landfills
This paper discusses the possibility of higher landfill construction through steeper slopes. For this purpose the shear strength of the landfill material (municipal solid waste) and the stability of the final cover were analyzed using computer models. To acquire proper input parameter for this model, laboratory test were conducted partially in a purpose-built shear box and in a normal shear box. The results obtained from these tests were compared against known literature. Suggestions were made on the possibility of steeper slope landfill construction con-sidering the necessary final cover as well.
Security Risk of Landfill Gas - Hazard Potential and Defensive Measures
The present work “Security Risk of Landfill Gas” has the goal to analyze, identify and minimize risks and hazards resulting from the emergence of landfi ll gas through a comprehensive approach. The fact that accidents happen repeatedly in this area, shows the security policy defi cit and thus the relevance of this work.
Aeration of the Landfill Pill; Effects on Groundwater Contamination
At the former landfill Pill in Tyrol, Austria groundwater contamination was caused by high Ammonium loads of up to 20 mg/l. Biodegradable nitrogen was specified as the cause of groundwater pollution by ammonium. However, other substances were hardly noticeable. Ammonium is generated within the landfill body through anaerobic decomposition of organic matter.
Climate changeState of the art - options for mitigation and adaptation
A Prognosis, and Perhaps a Plan, for Geoengineering Governance
The idea of global climate engineering exists, but there are no global institutions capable of making legitimate choices about deploying and managing such an intervention. On the other hand, sub-global regions, mostly individual countries could, and in fact currently do, deploy smaller interventions against natural disasters without global decision-making. If governments actively plan to cooperate on developing and managing interventions to avoid, redirect or modify severe weather natural disasters related to climate change they may along the way learn about how to set intervention goals, make intervention choices, assess outcomes of the intervention and adapt the interventions accordingly. These crucial deliberation and management skills could grow as the interventions grow in response to more severe impacts. Governments should plan to use collaboration on natural disasters as a vehicle for developing the institutional capacity to manage the global climate.
Making Sense of Carbon Market Development in China
China has recently begun promoting market-oriented policy instruments to reduce carbon emissions as part of its domestic climate strategy. A centerpiece of this new policy approach has been the launch of pilot carbon markets in seven distinct regions. Based on extensive field visits to all pilot markets under development, this analysis assesses the implications of this “bottom-up” approach to carbon market development for the prospects for nationwide carbon trading in China. It concludes that initiating carbon trading in the seven regions across China with insufficient capacity building, an extremely compressed time frame, and little bureaucratic coordination has engendered challenges for the development of a national carbon market. Nevertheless, these pilots have advanced the prospects for sustained climate action in China at the local Level through their contribution to indigenous technical and human capacity as well as through engaging new stakeholders, including domestic and international actors, supportive of the development of an eventual national trading scheme.
Climate Change Mitigation from the Bottom Up: Using Preferential Trade Agreements to Promote Climate Change Mitigation
This paper proposes the introduction of a regional model for promoting climate change mitigation as an alternative to the present structure of the United Nations Framework Convention on Climate Change (UNFCCC)/Kyoto Protocol framework. Given the proliferation of preferential trade agreements (PTAs) – especially in the form of bilateral treaties – in the international trading system, this paper advocates creating PTAs with strong climate change chapters, thus embedding climate goals within bilateral/trilateral/plurilateral trade agreements. Involving major greenhouse gas (GHG) emitters through PTAs which include climate chapters can be an effective avenue towards reducing GHG emissions, and could therefore facilitate the ultimate goal of creating an effective global climate regime. This option may therefore be worth exploring.
Getting Ahead of the Curve: Supporting Adaptation to Long-term Climate Change and Short-term Climate Variability Alike
Climate change mitigation, the moderation of temperature increases through reductions in emissions or emissions growth, remains the central component of global climate change action under the United Nations Framework Convention on Climate Change (UNFCCC). Nonetheless, climate change adaptation is playing an ever more prominent role at the UNFCCC annual meetings, the Conferences of the Parties (COPs), as exemplified by the creation of the Green Climate Fund in 2009 in Copenhagen with the goal of mobilizing $100 billion per year by 2020 for climate change activities including adaptation. Many other entities are also financing adaptation, such as the World Bank’s Strategic Climate Fund, to which $920 million has been pledged.
IPCC report shows growing risks from already-present climate change
Climate change is already having substantial and widespread impacts around the world, according to the latest report from the Intergovernmental Panel on Climate Change (IPCC). Drawing on a larger body of evidence than ever before, it highlights a wide range of risks in vital areas such as food supply, human health and economic development.
ConsumptionHow much is sufficient, and how much is too much?

Food Waste Generation in Germany
Based on a study which aimed to calculate the generation of food waste in Germany along the food supply chain (FSC), to estimate the share of prevention, to demonstrate the causes of food waste as well as to design measures for food waste prevention in Germany, the paper focuses on generation and composition as well as on data gaps which lead to uncertainties in the estimations.
Composition Analyses of Food Waste – the Influence of Food Packaging
The disposal of food which would have been fit for human consumption, has become an increasingly discussed topic in recent years. In order to identify and implement effective measures for its reduction, data about the quantity and composition of food waste are required. However, currently available data are fragmentary and reveal significant information gaps and uncertainties.
Environmental Product Declarations for Complex Electronical Equipment
Environmental information about products is increasingly asked for by consumers or industrial clients. Depending on the target group this information is corresponding to the basic standards ISO 14021, 14024 and 14025 more or less complex. Well-known examples are the German "Blue Angel" or the Austrian eco-label which are predominantly designed for final consumers.
Food in Household Waste – Amounts, Indicators and Economic Relevance
Wasting food is an increasing subject for discussion because of increasingly importance of the food and resources security. This master thesis gives answers and insights to food waste related questions, but most importantly to the question which amount of food waste emerges in domes-tic households in Germany.
Europe's demand for resources reaching far beyond its borders
Demand for materials is so intense that between 20 and 30 % of the resources we use in Europe are now imported. With the boom in international trade, EU consumption and production damage ecosystems and human health far beyond Europe’s borders, according to a report published by the European Environment Agency (EEA).
Unsustainable consumption – the mother of all environmental issues?
Consumption of products and services impacts the environment in many different ways. For example, the things we buy contribute, directly or indirectly through the product lifecycle, to climate change, pollution, biodiversity loss and resource depletion in Europe and other regions of the world.
The ocean - biggest garbage dump on earthIt belongs to everybody and nobody, yet - or that's why? - we are so heedless about it.
Current State and Potential for Increasing Plastics Recycling in the U.S.
Plastics are a relatively new man‐made material that provides vast material benefits throughout their useful lifespan. However, their end of life disposal currently leaves much to be desired. The U.S. EPA estimates that 30 million tons (16.8% according to the EPA estimate of MSW and 8% according to the BioCycle/Columbia national survey) of the municipal solid waste (MSW) generated in the US annually is in the form of plastics.1 Of this amount only 7% is recovered for recycling , mostly in the form of polyethylene, and roughly 10% is combusted in waste‐to‐energy (WTE) facilities to generate electricity. The remainder of plastic wastes are landfilled, which is clearly a loss of non‐renewable, fossilbased resources. Also, plastics litter in some cases poses a threat to human health and also threatens other ecosystems. For example, there is an estimated 100 million tons of plastic litter in the oceans, with millions more tons added each year.
Biologists record increasing amounts of plastic litter in the Arctic deep sea
studies confirm that twice as much marine debris is lying on the seabed today compared to ten years ago.
Bremerhaven, 22nd October 2012. The sea bed in the Arctic deep sea is increasingly strewn with litter and plastic waste. As reported in the advance online publication of the scientific journal Marine Pollution Bulletin by Dr. Melanie Bergmann, biologist and deep-sea expert at the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association. The quantities of waste observed at the AWI deep-sea observatory HAUSGARTEN are even higher than those found in a deep-sea canyon near the Portuguese capital Lisbon.
Toxic Mine Waste Threatens Waters
Each year, mining companies dump more than 180 million tonnes of hazardous mine waste into rivers, lakes and oceans worldwide, threatening vital bodies of water with toxic heavy metals and other chemicals poisonous to humans and wildlife, according to a report released today by two leading mining reform groups.

Soil application of organic waste – sources or sinks of GHGs?
Organic waste material is used to return nutrients to soil to preserve and improve soil fertility. Several studies indicate that agricultural activities are contributors to greenhouse gas (GHG) emissions (Denman et al., 2007; USEPA, 2011). Release of Methane, Carbon dioxide and Nitrous oxide was measured from soil application of organic residues (“empty fruit bunch” (EFB), “fiber” and “shell”) on palm oil plantations in Indonesia using a flux chamber and a photoacoustic field gas monitor (INNOVA 1412-5). The results show that the application of organic residues onto soil resulting in the release of GHGs.
Potential and Constraints of Biochar for Carbon Sequestration and Soil Improvement
Current mitigation efforts of global climate change such as Carbon Capture and Storage (CCS) and land use change (especially no tillage agriculture, desertification control and agriculture to pasture conversion) are ineffective in reducing anthropogenic CO2 emissions. New promising techniques do not only remove atmospheric CO2 but also use it (Carbon Capture and Use, CCU). Such techniques comprise use of solid carbon (biochar) for soil improvement. The existence of intensively used anthropogenic soils in central Amazonia (terra preta) proves that this is principally possible in the long term (for millennia).
Environment: Commission calls for a stronger response to soil degradation
Soil degradation is a worrying phenomenon in the EU. Between 1990 and 2006, at least 275 hectares of soil per day were permanently lost through soil sealing – the covering of fertile land by impermeable material – amounting to 1,000 km² per year, or an area the size of Cyprus every ten years. Soil erosion by water is estimated to affect 1.3 million km² in Europe, an area equivalent to 2.5 times the size of France. Soil degradation affects our capacity to produce food, prevent droughts and flooding, stop biodiversity loss, and tackle climate change. These are some of the main findings of two new reports on the policy and scientific aspects of European soil presented by the European Commission.
Green potential of our industrial past
Manipulating the soil in urban and industrial areas in order to capture more carbon from the atmosphere is the “best resource we have to begin to mitigate human CO2 emissions”, experts claim.
DiversityThe variety of flora and fauna is called biodiversity - a frequently neglected part of this is cultural diversity, which the UNESCO refers to as being as important for humankind as biodiversity is for nature.

Marine Biodiversity and Climate Change
There is now a general consensus that global warming is real and that one of the factors forcing climate change is the anthropogenic addition of greenhouse gases to the atmosphere. The implications of climate change for ecosystems are, however, not yet entirely understood. As the oceans cover 71% of the earth’s surface and play a major role in the global carbon cycle, it is important to understand how a changing climate will affect the biota not only of terrestrial systems, but also of the marine environment.
Taking Adaptation Value Seriously: Designing REDD to Protect Biodiversity
The inter-related challenges of climate change and biodiversity loss present serious threats to the future of life on earth, while posing some of the most challenging issues in international law and policy. Climate change will exacerbate biodiversity loss, while continued loss of biodiversity will undermine efforts to adapt to a changing climate. The issues are nowhere more closely linked than in tropical forests, where challenging governance and equity questions have undermined prior international cooperative efforts.
Protected areas: a key element of Europe's sustainable future
Europe's protected areas play a key role in protecting biodiversity. But they are also a critical component of the continent’s economy, contributing over EUR 15 billion a year in jobs, food, and other services for the people of Europe. 2012 marks both the 20th anniversary of the most important international multilateral agreement on Biodiversity, the UN's Convention on Biological Diversity and of the most important EU piece of legislation on nature and biodiversity, the EU's Habitats Directive. As today, 22 May, is international biodiversity day, it provides an ideal opportunity to examine the state of protected areas today and the many benefits they provide.
Growing world trade makes food production cheaper – at the expense of the environment
Further opening of the markets for agricultural products leads to lower production costs for food. This will happen at the expense of the environment though, if for example forests are turned into cropland. The conflict of interests between food production and climate protection is now shown by scientists from the Potsdam Institute for Climate Impact Research (PIK) in calculations for the years 2005 to 2045. For the first time, the effects of an advancing liberalization of agricultural trade were comprehensively analyzed through computer simulations, focusing both on the economic impacts and on those on land use and nature.

Comparison of the Pretreatment Efficiency Between UF and Sand Filtration of a Desalination Process Using a Reverse Osmosis Membrane
The pretreatment process is known to be the dominant infl uence factor in the RO process. Therefore, this study was done to evaluate effi ciency by comparing membrane fi ltration (UF) with two-stage sand fi ltrations for pretreatment of the RO process. SDI and particle size distribution of feed sea water and pretreatment permeate water were measured to analyse the infl uence of the fouling factor of the RO membrane. The SDI removal effi - ciency of the UF membrane fi ltration process was better than that for the sand fi ltration. The particle fraction under 20 μm of feed sea water and sand fi ltration permeate water was more than 93 % and 97 %, respectively. As for results of operation, micro particles were not removed by the sand fi ltration. Furthermore, although the UF membrane process had a higher recovery than the sand fi ltration process, the UF membrane process represented low RO resistance.
Better ROI and Lower Emissions – Smart Decisions Based on Energy Efficiency Facts Reduce the Emissions and Improve Your OPEX –
Today`s world has many obligations; the energy consumption in general must be reduced, the emissions as per Kyoto protocol should be reduced to the 2005 level and there should be a shift from coal fired and nuclear power plants into renewable energy sources. Also the management in industry starts to request energy savings to compensate the high energy costs. Now, as by the end of 2011, the new ISO 50,001 Energy Management System shall be implemented for systematically saving the precious energy while reducing the greenhouse gas emissions. The world needs will soon be fundamentally changed. This ambitious goal must be achieved in less than 20 years. Each one of us is asked every day to save energy and resources and it all depends and starts with each human being.
EFFICIENCY CONTROL OF LANDFILL IN-SITU AERATION BASED ON LEACHATE CHARACTERISATION
The current emission potential of old municipal solid waste (MSW) landfills is mainly influenced by the degradation state of organic matter. During the phase of active landfill aftercare air supply affects the current and residual emission potential in a positive way. The shift from anaerobic to aerobic conditions is induced by the process of in-situ aeration. Accelerated organic matter transformation and mineralisation cause environmentally relevant emissions to decline. Reduction of substantial gaseous emissions is paralleled by decreasing concentrations of organic leachate compounds and inorganic mineralisation products.
Europe needs to use water more efficiently
Europe needs to redouble efforts in using water more efficiently to avoid undermining its economy, according to a new report from the European Environment Agency (EEA). Inefficient water use impacts hard on the resources needed by ecosystems and people, both vital assets for European productivity and security.
