The EU-funded research project HyFlexFuel recently successfully produced biocrudes via hydrothermal liquefaction (HTL) from a variety of biomasses, including sewage sludge, food waste, manure, wheat straw, corn stover, pine sawdust, miscanthus and microalgae in a pilot-scale continuous HTL plant at Aarhus University (Denmark).
Researchers at the Swiss Federal Institute of Technology (ETH) Zurich, Switzerland, have developed a carbon-supported platinum nanoparticle catalyst that can achieve complete hydrocracking of polypropylene into liquid hydrocarbons (C 5 –C 45 ). Polypropylene constitutes about 30% of all plastic waste.
The Swiss company Climeworks is building the world’s largest direct air capture (DAC) and storage facility for converting atmospheric CO 2 to rock in Iceland. C using waste heat from a nearby geothermal plant to release the CO 2 molecules. Iceland is one of several places on Earth offering the ideal conditions for this process.
In this second stage, hydrogen from regenerative energy sources is converted into methane (CH 4 ), i.e. synthetic natural gas, using CO 2 from a bio-ethanol plant. Type of CO2 source (biogas; waste water; atmosphere). Local consumers (low consumption; municipal region; rural area).
Due to the high reaction temperatures, a proportion of the water is converted back into hydrogen by the water-gas shift reaction. Both hydrogen production and methanization continuously generate waste heat. Empa researchers see further potential for optimization in the heat required for this CO 2 desorption.
Together with the partners Ineratec GmbH ( earlier post ) and Energiedienst Holding AG , the company has plans for a new pilot facility for the production of e-diesel in Laufenburg, in Canton Aargau (Switzerland). To produce it, the power-to-liquid plant converts surplus hydropower into synthetic fuel.
It seemed to me that recent improvements in reactor designs gave nuclear plants even more potential to deeply decarbonize societies at reasonable cost, while operating safely and dealing with nuclear waste in a responsible way. Still, it turns out you can’t easily get a sample of nuclear waste like americium; you have to work up to it.
In addition to domestic waste, agricultural pollution and industrial waste are also to blame for the rise of micropollutants in our waterways. Pioneer in the Treatment of Micropollutants In 2016, Switzerland introduced legislation mandating that wastewater treatment plants remove micropollutants from wastewater. Their goal?
ABB India Asea Brown Boveri (ABB) is a Switzerland based multinational company and they manufacture electric motors for electric vehicles. Tork Motors has developed indigenous motor technologies that provide exceptional acceleration, range, and efficiency. On average, electric vehicle motors in India have an efficiency rating of 85% to 95%.
One of these intrepid road testers sent to try the fuel efficiency of Volvo’s new DRIVe models-the V70 and S80- was our reporter Tom Stewart, who kindly kept a diary to explain how Volvo converted a confessed ‘lead-foot’ to an eco-angel. The DRIVe Story. By Tom Stewart.
