Laboratory-scale wetlands remove toxic veterinary drugs from wastewater

Constructed wetlands can effectively remove veterinary drugs from wastewater, preventing contamination of the environment, research suggests. A recent study has demonstrated that laboratory-scale constructed wetlands were able to remove between 94 and 98% of two commonly used antibiotics from pig farm wastewater.

Producing environmentally friendly biodegradable plastics from vegetable waste

Using vegetable waste to produce bioplastics can provide sustainable alternatives to non-biodegradable plastic, new research has found. The biodegradable plastic developed for this study, produced using parsley and spinach stems, cocoa pod husks and rice hulls, have a range of mechanical properties comparable to conventional plastics which are used for products from carrier bags to kitchenware and computer components.

The impacts of large-scale Concentrated Solar Power on the local environment

Construction of Concentrated Solar Power (CSP) plants – electricity generation which concentrates sunlight to generate heat – can have a range of negative effects on wildlife, but these effects are short lived, new research has found. Once in use, CSP plants can even have some positive effects, reducing soil erosion, for instance.

Solar cell efficiency boosted with pine tree-like nanotube needle

‘Dye-sensitised solar cells’ (DSSCs) are an alternative to traditional silicon photovoltaic (PV) cells. They have a number of advantages over traditional PV solar cells, including greater flexibility and lower manufacturing cost, but they are less efficient at turning sunlight into electricity. Taking inspiration from nature, new research has doubled their efficiency using pine tree-shaped nanotubes.

New energy-efficient manufacture of perovskite solar cells that rivals silicon solar cells

‘Perovskite solar cells’ (PSCs) are less costly than conventional silicon solar cells, but one of their key components is energy-intensive to manufacture as high temperatures are needed. Now researchers have identified new alternative materials for this component which cut energy demands as they can be produced at low temperatures.

Titanium dioxide-water nanofluids enhance the performance of solar collectors

Adding nanoparticles to water in solar collectors, which are used to capture the sun’s energy, can considerably improve their performance, a recent study on nanofluids has found. The energy efficiency of the collector can be increased by up to 76.6% when using water containing 0.1% by volume of titanium dioxide nanoparticles, compared with water alone.

Methods to increase indium supplies for the manufacture of thin-film solar cells

Shortages of indium, a key metal found in thin-film solar cells, could limit their large-scale deployment in the future. A new study has outlined four ways that indium supplies could be increased to meet future demand. For example, indium could be extracted more efficiently from zinc ores, or historic wastes containing indium could be processed to extract the element.

Cool pavements to reduce urban heat islands: the state of the technology

Cool pavements, which can be used to reduce the Urban Heat Island (UHI) effect, where towns and cities are warmer than surrounding rural areas, have been reviewed in new research. The review found that reflective pavements can reduce temperatures by up to 20°C and are more durable than evaporative pavements, which are less effective at temperature reduction but may have other benefits, such as reducing runoff.

Wave and tidal energy plants are ‘green’ technologies

Environmental impacts for a wave energy device, tidal stream and tidal range plants are potentially eight, 20 and 115 times lower respectively than for coal-generated power, averaged over five impact categories. An assessment of the amount of metal used by these technologies, however, shows an impact respectively 11 and 17 times higher than for coal- and gas-based power generators. These are the findings of a recent study, which compared the life-cycle environmental impacts of various wave and tidal energy devices with other forms of energy generation. The researchers conclude that wave and tidal energy plants qualify as ‘green’ technologies according to their definition, but that their impacts on marine ecosystems need further research.

A carbon-free future for the Canary Islands possible by 2050

The Canary Islands have the potential to become carbon neutral by 2050, a new study indicates. This could be achieved by shifting to a 100% renewable energy supply, improving energy efficiency and building new grid connections between islands. Energy solutions for small island regions, such as the Canaries, could act as role models for larger systems, as well as similar islands, the researchers suggest.

ALMA finds unexpected trove of gas around larger stars

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) surveyed dozens of young stars -- some Sun-like and others approximately double that size -- and discovered that the larger variety have surprisingly rich reservoirs of carbon monoxide gas in their debris disks. In contrast, the lower-mass, Sun-like stars have debris disks that are virtually gas-free.

Planet found in habitable zone around nearest star

Astronomers using ESO telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This rocky world is a little more massive than the Earth and is the closest exoplanet to us -- and it may also be the closest possible abode for life outside the Solar System. A paper describing this milestone finding will be published in the journal Nature on 25 August 2016.

Discovery one-ups Tatooine, finds twin stars hosting three giant exoplanets

A team of Carnegie scientists has discovered three giant planets in a binary star system composed of stellar ''twins'' that are also effectively siblings of our Sun. One star hosts two planets and the other hosts the third. The system represents the smallest-separation binary in which both stars host planets that has ever been observed. The findings, which may help explain the influence that giant planets like Jupiter have over a solar system's architecture, have been accepted for publication in The Astronomical Journal.

Images from Sun's edge reveal origins of solar wind

Ever since the 1950s discovery of the solar wind - the constant flow of charged particles from the sun - there's been a stark disconnect between this outpouring and the sun itself. As it approaches Earth, the solar wind is gusty and turbulent. But near the sun where it originates, this wind is structured in distinct rays, much like a child's simple drawing of the sun. The details of the transition from defined rays in the corona, the sun's upper atmosphere, to the solar wind have been, until now, a mystery.

The economic impact of reducing food waste in Germany, Poland and Spain
