Meal planning, shopping lists, soup from shrivelled vegetables – all valid ways of lowering food waste.
Scientists, meanwhile, are constantly thinking of ways to reduce methane generated by food waste dumped at landfill sites. Using vegetables for solar cells, for example, or bread for drinks.
Now researchers have discovered that leftover food can be converted to sustainable aviation fuel (SAF) – rescuing the unused energy.
Paraffins, particularly suitable for SAF, are generated during the decomposition process before any methane is produced.
Thus, overall greenhouse gas emissions could be reduced by 165% compared with using standard aviation fuel.
The significant reduction in soot formation and aerosol emissions could also have a serious impact.
