"History teaches us that men and nations behave wisely once they have exhausted all other alternatives"

"Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs."

The Report of the U.N. Brundtland Commission, Our Common Future, 1987
"If there are to be problems, may they come during my life-time so that I can resolve them and give my children the chance of a good life."

Could waste to energy help to close the loop?
Wed / 31.01. @ 11:30
The world is facing ever increasing amounts of waste, which impairs public health and pollutes the environment. More than half the world’s population does not have access to regular waste collection, while some of the waste management practices are inadequate. Each year, nations around the globe generate 1.3 billion tonnes of waste, the figure which is expected to rise to 4 billion tonnes by 2100. Among the biggest waste producers in the world are the United States, China, Brazil, Japan and Germany. Furthermore, the United Nations Environment Program predicts that the amount of waste will probably double in lower-income African and Asian cities because of population growth, urbanization and rising consumption. The steady increase in solid waste quantities, especially packaging waste in which plastic waste makes most of it, is a direct consequence of economic growth, where product disposal after use is neglected. This is particularly pronounced in a "flood" of cheap but non-durable products on the market. Consequences are significant, and the problem of solid waste is recognized as a priority environmental problem all around the world. The European Union is strongly pushing the agenda of circular economy in which promotes recycling and recovery of waste as an imperative in waste management. Along with favoring the environment such new paradigm is consequence of the need to extract useful raw materials from waste streams (still one-third of plastic waste ends up on EU landfills). Despite the high recycling targets for near future in the EU, not all the waste can be favorably recycled due to technical, economic or environmental reasons. One way of dealing with waste is incineration, which if done properly can be used to recover energy from it. Also by thermally treating the waste, potentially harmful and/or toxic substances are removed from the material recovery flow to avoid inclusion of these dangerous components into material (e.g. intended for use in food chains). Apart from energy, different types of energy vectors and chemicals can be produced from various sorts of waste and waste materials using different technologies, like refuse derived fuels, transport fuels, synthetic gas, biomethane, monomers, etc. Finally, the presentation will try to address a central issue: Is there a place for energy recovery of waste in the circular economy paradigm? or Can recycling and incineration coexist?

Fear of Change

The transition of energy systems towards becoming completely based on renewable energy resources is absolutely not a new topic. Ways to go that way do exist for many regions, countries, and even continents. Advantages fo going these ways are clear. And the advantages are leading far beyond of avoiding climate change and global warming. Apart from few countries whose prosparity is based on export of carbon based fuels most also would benefit from this transition. Nevertheless, resistance towards the transition towards renwables is growing. Persistant forces are growing and discussions are getting harder. The presentation will touch the following topics: What is the difference between solving the ozon hole problem and the global warming problem? Why do politicians talk about the necessity of energy transition and even know details and necessities on the way to go for but are acting in contrary to their talks? Why is coupling of energy sectors of big importants but regulation is hindering its implementation. As the author konws best the German case of Energy Transition most examples are dealing with this part of the world. But outlooks to other countries - also Brasil - are provided, too.

Increasingly concerns about social, economic and environmental conflicts demand metrics to evaluate their consequences helping avoid or mitigate their negative impacts. The basic concept of sustainable development involves these three interdependent spheres: economic, environmental and socio-political proposing that the solutions preserve the ability of the future generations to meet their own needs. Quantitative accounting of these impacts requires tracking indicators from organizations, government, and individuals that reveal the path to sustainable development footprints. Sustainable development can be regarded as the path to achieve sustainability. Thus, sustainability is associated to multidimensional complex systems, and, today, there is no standard methodology in choosing the required indicators or in standardized methods capable to analyze the results and to achieve acceptance of perceived successes. There are various suggested ways of to achieve this objective. This lecture presents a theoretical framework that suggests a possible path to advance the understanding of quantitative sustainability. We discuss perspectives of adopting procedures of metrology into sustainability assessments and use established rules to aggregate commensurable indicators into a single composite sustainability indicator. We discuss the following features: (a) proper definition of the system; (b) consider specific subsystems or dimensions; (c) construct the composite indicator; (d) the choice of the appropriated metrics according to their ability to distinguish specific states of the system in relation to a predefined reference state; (e) use statistical methods to: (i) estimate uncertainties; (ii) use uncertainties to asses impacts of variations in the indicators on the output of the system (sensitivity analysis); (iii) use uncertainties and sensitivity analysis to assess the robustness of the model used to represent the sustainability system. This model framework applied to analyze the six BRICS´countries sustainability of a biofuel supply chain and their rank of sustainable competitiveness.
