30 August 2015, Science Daily, Discarded electronics mismanaged within Europe equals about 10 times the volume of e-waste exported. Mismanagement of discarded electronics within Europe involves a volume 10 times that of e-waste shipped to foreign shores in undocumented exports, according to a comprehensive 2-year investigation into the functioning of the used and waste electronics market. The European Union-funded project, Countering WEEE (waste electrical and electronic equipment) Illegal Trade (CWIT), was undertaken by INTERPOL, United Nations University (UNU), United Nations Interregional Crime and Justice Research Institute, the WEEE Forum, the Cross Border Research Association, Zanasi & Partners and Compliance and Risks. The project found that in Europe just 35% (3.3 million tonnes of 9.5 million tonnes) of used (but still functioning) and waste electronics and electrical equipment discarded by companies and consumers in 2012 wound up in official collection and recycling systems. The other discarded electronics — 6.2 million tonnes in all — was either exported, recycled under non-compliant conditions or simply thrown in waste bins. The study estimates 1.3 million tonnes of discarded electronics departed the EU in undocumented mixed exports, of which an estimated 30% (about 400,000 tonnes) was electronic waste; and 70% functioning equipment.

29 August 2015, Climate News Network, Climate models may misjudge soils’ carbon emissions. How soil organisms cope with decaying vegetation is much less certain than climate models suppose, researchers say, and carbon emission estimates may be wrong. Some of the microscopic creatures which live in the soil are able to digest dead plants and trees, turning their contents into gas and minerals. But researchers say their work show that our understanding of how organic material is decomposed is fundamentally wrong, calling into question some current climate models. The researchers, from Lund University, Sweden, and the University of New Hampshire, USA, have published their study in the journal Ecological Monographs. They say it means that climate models which include micro-organisms in their estimates of future climate change must be reconsidered. When plants or trees die, their leaves and branches fall to the ground and the organic matter which is absorbed by the soil is then decomposed, mainly by the activity of fungi and bacteria, which convert the dead materials into the main greenhouse gas, carbon dioxide, and mineral nutrients. Until now, the Lund team says, scientists had thought that high-quality organic materials, such as leaves that are rich in soluble sugars, were mainly decomposed by bacteria, leaving the lower-quality matter, like cellulose and lignin, to be broken down mainly by fungi. Expectations confounded. Previous research has suggested that organic material decomposed by fungi results in less CO2 and nutrient leakage compared with matter decomposed by bacteria. This is important for the climate models in use today, as any change in the loss of CO2 and mineral nitrogen would alter the soil’s contribution to greenhouse gases and eutrophication, the process in which the release of excessive chemical pollution causes algal blooms in watercourses.

28 August 2015, The Conversation, The ‘green-tech’ future is a flawed vision of sustainability. What does your vision of a sustainable future look like? Some people imagine a scenario whereby technology solves the world’s most pressing environmental problems. In this world we all drive electric cars and have solar panels on our roofs that power our air conditioners and flat-screen televisions. We purchase “eco” products that provide all the convenience and comfort but without degrading the planet. We continue consuming and growing our economies, yet Mother Nature wins too. But I and my colleague Josh (who co-wrote this article) would argue that this vision of sustainability is flawed, and will in fact drive greater damage to the world, its ecosystems, and us. So how has this vision come to dominate? Why is ‘green-tech’ so popular? There seem to be three main reasons why the “green-tech” conception of sustainability is dominant. First, it is good for business. Sustainability is presented as something we can either purchase as consumers or sell as green entrepreneurs. There is no conflict here between consumer capitalism and sustainability, so the powers that be need not feel threatened. As the sustainable design website Inhabitat declares: “Design will save the world”. Read More here
28 August 2015, Climate News Network, Drought becoming the ‘new normal’ for Californians. Human impacts on global warming and water resources are threatening to turn the landscape of the US west into a dustbowl. One way or another, humans are to blame for the catastrophic drought in California that scientists say may be emerging as a “new normal”. Either humans have mismanaged the state’s water, or human-triggered global warming has begun to help turn America’s landscape of wine and roses into a dustbowl, according to two new studies. And the arguments have relevance extending far beyond the US west, as the European Drought Observatory has warned that much of mainland Europe is now caught up in the continent’s worst drought since 2003. The consequences of any drought could also be more enduring than expected. A research team in the US reports in the journal Ecological Applications that trees that survived severe drought in the US southeast 10 years ago are now dying – because of the long-ended drought.
