New water billing system could cut usage whilst being fair and profitable

DG ENV - Thu, 12/07/2018 - 16:40
An innovative system for pricing household water is proposed in a new EU-funded study1 researched in the US and UK. The tariff is designed by combining the economic value of water with reservoir storage data, and is intended to cut water usage during times of shortage by charging large-volume consumers a higher rate which increases as water becomes scarcer. The tariff increase subsidises water for other users, whilst also ensuring the system is economically stable. A case study suggests that the tariff could cut water consumption in the city of Valencia by up to 18%.

Dietary exposure to neonicotinoid-contaminated plant material poses risk to leaf-shredding invertebrates

DG ENV - Thu, 12/07/2018 - 16:40
Neonicotinoids are pesticides applied to plants to protect them from insects. The use of neonicotinoids may lead to contamination of aquatic environments through, among other routes, the input of contaminated plant material into waterways. While it is well established that direct exposure to contaminated water endangers aquatic invertebrates, scientists have now published findings indicating that dietary exposure through the consumption of contaminated plant material puts leaf-shredding species at increased risk. The researchers recommend that policymakers registering systemic insecticides (those whose active ingredients are transported throughout the plant tissues) consider dietary exposure, and its potential implications for ecosystem integrity, in addition to other exposure pathways.

Kerbside waste-collection schemes may need optimisation, highlights Portuguese study

DG ENV - Thu, 12/07/2018 - 16:40
A new analysis of waste recycling systems in Portugal highlights where kerbside (edge of pavement) collection systems could be optimised, to decrease their environmental impact. In this case, researchers found that the kerbside system was less favourable economically and environmentally due to more packaging and more fuel consumption per tonne of waste, compared to a system where recyclable materials are deposited by residents in large containers. But the researchers suggest that measures such as re-usable boxes and efficient collection routes could help to mitigate the impact of kerbside collection. While there is an environmental impact from waste collection, processing and disposal, this study only focused on the collection phase.

Tackling mercury pollution in the EU and worldwide – November 2017

DG ENV - Thu, 12/07/2018 - 16:40
Mercury is a heavy metal that is well known for being the only metal that is liquid at room temperature and normal pressure. It is also a potent neurotoxin with severe global human health impacts. It can be converted from one form to another by natural processes, and, once released, actively cycles in the environment for hundreds to thousands of years before being buried in sediment. This In-Depth Report from Science for Environment Policy summarises the latest scientific studies and research results on mercury pollution in the global environment.

Potentially toxic elements in European soils mapped by researchers

DG ENV - Thu, 12/07/2018 - 16:40
A new study has mapped levels of chemical elements found in European agricultural soils. In most places, unusually high concentrations are linked to geology, such as high levels of arsenic in the Massif Central in France. Human activity is to blame in some small areas, for example high concentrations of mercury were found near London and Paris. Abnormal concentrations, both too low and too high, could pose an environmental risk. This new data can be used in conjunction with the REACH Regulation1 and can help identify areas where action may be needed in relation to toxic elements in the environment.

Renewable-energy technologies can help meet the increased cooling demand in cities due to climate change

DG ENV - Thu, 12/07/2018 - 16:40
The available and emerging renewable technologies suitable for urban environments have been assessed in a recent study. Wind and solar technology can now be integrated into building design, and smart grids and metering can more efficiently manage energy production and demand at a local level. Investing in community-level renewable-energy projects can, therefore, help meet the future energy needs of towns and cities.

Nanomaterial alternatives assessment: a powerful tool for identifying safer options

DG ENV - Thu, 12/07/2018 - 16:40
Judging whether to replace a hazardous conventional chemical in a product with a nanomaterial — i.e. to assess which is the safer alternative — is challenging for many reasons. A new study suggests that chemical-alternative assessment frameworks could be adapted to better assess engineered nanomaterials with the help of new tools which provide data on hazards of, and exposure to, nanomaterials.

Eco-innovation encouraged by regulatory measures and R&D — especially important for Eastern Europe

DG ENV - Thu, 12/07/2018 - 16:40
The factors enabling eco-innovation have been analysed across 19 European countries in a new study. Regulations and environmental subsidies were found to be more important factors in Eastern Europe than in wealthier Western European countries. External research and development (R&D) was also more relevant in Eastern Europe, demonstrating the need for specific technology transfers from other countries and competitors.

Volume of leachate and environmental impact from landfills reduced — but legacy effects remain

DG ENV - Thu, 12/07/2018 - 16:40
Landfill leachate is the liquid that seeps through or out of waste deposits in landfill sites. EU regulations, such as the Landfill Directive1, have significantly reduced the volume of leachate produced, a study on leachate management in Ireland has found. Leachate, mainly from younger landfills in Ireland is, however, stronger since implementation of the legislation, and the researchers say the future treatment of leachate under stricter environmental protection regulations will continue to be a long-term concern for landfill operators and regulators.
