Full of beans: Coffee grounds to help power London’s buses

LONDON: Waste coffee grounds will be used to help fuel some of London’s buses, Royal Dutch Shell and clean technology company bio-bean said on Monday.
A new biofuel, which contains part coffee oil, is being added to the London bus fuel supply chain where it can be used without the need for modification, the companies said in a statement.
Bio-bean and partner Argent Energy have so far produced enough coffee oil to power one bus for a year, if used as a pure-blend for the 20 percent bio component and mixed with mineral diesel to form a B20 fuel, they said.
Transport for London has been turning to biofuels to curb carbon emissions, trialling a fuel made with used cooking oil from the catering industry, the transport operator said on its website.
Bio-bean said the average Londoner drinks 2.3 cups of coffee a day, producing over 200,000 tons of waste a year. It collects waste grounds from high street chains and factories, which are dried and processed to extract coffee oil.
“It’s a great example of what can be done when we start to reimagine waste as an untapped resource,” bio-bean founder Arthur Kay said.
The coffee fuel technology has been supported by Shell.

Europe, Japan send spacecraft on 7-year journey to Mercury

  • Once the spacecraft arrives in late 2025, it will release two probes that will independently investigate the planet

TOKYO: European and Japanese space agencies say an Ariane 5 rocket has successfully lifted a spacecraft into orbit for a joint mission to Mercury, the closest planet to the sun.
The European Space Agency and Japan Aerospace Exploration Agency say the BepiColombo spacecraft successfully separated and was sent into orbit from French Guiana early Saturday to begin a seven-year journey to Mercury.
The mission is complicated by the intense gravity pull of the sun, forcing the spacecraft to take an elliptical path that involves two fly-bys of Venus and six of Mercury itself.
Once the spacecraft arrives in late 2025, it will release two probes that will independently investigate the surface and magnetic field of Mercury.
