AP Moller-Maersk is throwing its weight behind US-based start-up WasteFuel in a bid to increase sustainable bio-methanol production.

The Danish giant's corporate venture arm, Maersk Growth, is taking a stake in the California-based company with the goal of speeding up production and expanding the geographical network for sourcing the alternative fuel.

WasteFuel focuses on turning waste into sustainable aviation fuel, green bio-methanol and renewable natural gas.
