As there is a huge problem building with plastics I really don't see that disposing of used cooking oil by putting it a plastic bottle (which should really be recycled) and sending it to landfill is a particularly good solution for anything but the short term.
Used cooking oil can be converted to fuel for cars, lorries etc. It must be possible to add used cooking oil to domestic waste recycling to increase the uptake of this fuel.
Orchids and other lovely plants that don’t need a lot of attention
